Have no idea if you guys will know but firstly does the Excalibur support AT commands?
secondly, how would I connect using VC# 2008 Express
code follows
Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;
namespace phoneBackup
{
public partial class Form1 : Form
{
SerialPort sp = new SerialPort();
public Form1()
{
InitializeComponent();
programStatus.Text = "Connecting...";
}
private void Form1_Load(object sender, EventArgs e)
{
sp.Open();
if (sp.IsOpen == true)
{
programStatus.Text = "Connection: " + sp.IsOpen.ToString();
//status
sp.ReadTimeout = 500;
sp.WriteTimeout = 500;
getStatus();
}
else
{
programStatus.Text = "Not connected, relaunch";
}
}
private void button1_Click(object sender, EventArgs e)
{
try
{
textBox1.Text = "";
sp.WriteLine("AT+CGMM");
sp.Write("AT+CGMM");
getStatus();
}
catch (System.Exception ex)
{
textBox1.Text = ex.Message.ToString();
}
}
private void button2_Click(object sender, EventArgs e)
{
try
{
textBox1.Text = "";
textBox1.Text = "Reading..." + Environment.NewLine;
textBox1.Text += "Status: " + Environment.NewLine;
getStatus();
}
catch (Exception ex)
{
textBox1.Text = "error " + ex.Message.ToString();
}
}
private void getStatus()
{
textBox1.Text += "BaseStream: " + sp.BaseStream.ToString() + Environment.NewLine;
textBox1.Text += "BaudRate: " + sp.BaudRate.ToString() + Environment.NewLine;
textBox1.Text += "Bytes to read: " + sp.BytesToRead.ToString() + Environment.NewLine;
textBox1.Text += "Bytes to write: " + sp.BytesToWrite.ToString() + Environment.NewLine;
textBox1.Text += "ReadTimeout: " + sp.ReadTimeout.ToString() + Environment.NewLine;
textBox1.Text += "Port Name: " + sp.PortName.ToString() + Environment.NewLine;
textBox1.Text += "Handshake: " + sp.Handshake.ToString() + Environment.NewLine;
textBox1.Text += "Data bits: " + sp.DataBits.ToString() + Environment.NewLine;
}
private void sp_DataReceived(object sender,
SerialDataReceivedEventArgs e)
{
textBox1.Text += Environment.NewLine + sp.ReadExisting().ToString();
}
private void button3_Click(object sender, EventArgs e)
{
textBox1.Text = "";
getStatus();
}
}
}
Output is
BaseStream: System.IO.Ports.SerialStream
BaudRate: 9600
Bytes to read: 0
Bytes to write: 0
ReadTimeout: 500
Port Name: COM1
Handshake: None
Data bits: 8
no matter which button is pressed

anyone cna help?
I just want to share my code for reading app.config file. I wrote it earlier for my current project - JWMD Stuick.
I just want it simple and clean and my/an alternative of (I never used it though) OpenNETCF.Configuration.
here's the code
PHP:
using System;
using System.Collections.Generic;
using System.Xml;
using System.Xml.XPath;
using System.IO;
namespace ApplicationConfiguration
{
public class Configuration
{
XmlDocument xmldoc;
string _applicationname = string.Empty;
string _appconfigfile = string.Empty;
Dictionary<string, string> _appSettings = new Dictionary<string, string>();
public Dictionary<string, string> AppSettings
{
get { return _appSettings; }
}
public Configuration()
{
string startup = System.Reflection.Assembly.GetCallingAssembly().GetName().CodeBase;
FileInfo fi = new FileInfo(startup);
this._applicationname = System.IO.Path.GetFileNameWithoutExtension(startup);
this._appconfigfile = System.IO.Path.Combine(fi.DirectoryName.ToString(), _applicationname + ".exe.config");
Read();
}
void Read()
{
xmldoc = new XmlDocument();
xmldoc.Load(this._appconfigfile);
XmlNodeList nodeCol = xmldoc.SelectNodes("//add");
if (nodeCol != null)
{
foreach (XmlNode thisNode in nodeCol)
{
string key = thisNode.Attributes["key"].Value.ToString();
string value = thisNode.Attributes["value"].Value.ToString();
this._appSettings.Add(key, value);
System.Diagnostics.Debug.WriteLine(key + ", " + value);
}
}
}
}
}
to make this work, make sure app config file is named the way Windows Forms rename the app.config.
e.g. your application name is "mysuperapplication" then the app config file must be "mysuperapplication.exe.config"
below is a application test.
Hey Guys!
I'm sitting in front of an XML-Problem for five days now and really don't know what's to do. Expect of asking you.
I want to write a small shopping list application that manages the data in an XML-File looking like that:
Code:
<?xml version="1.0" encoding="utf-8" ?>
<Items>
<Item>
<Name>Bananas</Name>
<Store>supermarket</Store>
<Repeat>true</Repeat>
</Item>
<Item>
<Name>LG E900 Optimus 7</Name>
<Store>superhandy</Store>
<Repeat>false</Repeat>
</Item>
(...)
I have a ListBox called ItemShowcase that I fill with instances of my ShowCaseEntry-Class
Reading Data from the FIle works perfectly with this code:
Code:
private void updateItemList()
{
// load XML-File
var items = XElement.Load("MissingItems.xml");
foreach (var a in items.Elements())
{
ShowCaseEntry sce = new ShowCaseEntry(a.Element("Name").Value, "Store: " + a.Element("Store").Value, false);
ItemShowcase.Items.Add(sce);
}
}
No Problem until here.
But now I want to add a new Iem to my XML-File.
I have 2 Textfields in what I ask for the Item-Name and Store-Name. Repeat is always true.
I tried that:
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
// XML-Datei Laden
var items = XDocument.Load("MissingItems.xml");
// neues Item erstellen
XElement newItem = new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat) );
// Hinzufügen und spreichern
items.Root.Add(newItem);
FileStream F = new FileStream("MissingItems.xml", FileMode.Open);
items.Save(F);
}
The last line give me the following Error:
Attempt to access the method failed: System.IO.FileStream..ctor(System.String, System.IO.FileMode)
Is anyone here who would help me?
You would save my weekend!
Thank you so much!
Best wishes and greets
Robby
Try something like this:
Code:
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
xml.Save(isoStream);
isoStream.Close();
First of all thanks for your answer.
Unfortunately I don't really know how to add the XML-Items.
Like this?
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
var items = XDocument.Load("MissingItems.xml");
XElement newItem = new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat));
items.Root.Add(newItem);
items.Save(isoStream);
isoStream.Close();
}
Another answer would be very nice
Best regards
Robby
I don't have time to test it but hopefully this works for you.
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
XDocument items = XDocument.Load(isoStream);
items.Element("Items").Add(
new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat)));
items.Save(isoStream);
isoStream.Close();
}
Thank you really much for your engangement, but there is still one problem.
In this line the program throws an XML-Error called "root element is missing":
XDocument items = XDocument.Load(isoStream);
How to explain the Load-Method that "Items" is my root Element?
Greets
Robby
Sorry my code had errors. This is tested and working.
Code:
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument items = XDocument.Load(isoStream);
isoStream.Close();
items.Element("Items").Add(
new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat.ToString())));
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
items.Save(isoStream);
isoStream.Close();
That code results in this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<Items>
<Item>
<Name>Bananas</Name>
<Store>supermarket</Store>
<Repeat>true</Repeat>
</Item>
<Item>
<Name>LG E900 Optimus 7</Name>
<Store>superhandy</Store>
<Repeat>false</Repeat>
</Item>
<Item>
<Name>Test Name</Name>
<Store>Test Store</Store>
<Repeat>False</Repeat>
</Item>
</Items>
I really, really thank you for your anxiety. Thank you for your time, but I just have one more error.
This line throwes an Isolated Storage Exception called "Operation not permitted on IsolatedStorageFileStream.":
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
You would save my week with a short answer!
Thank you so much till yet
Robby
It sounds like the file stream is already open somewhere else. If you are doing any other reads or writes to the file prior to your addxmlitem method you need to close the stream before calling addxmlitem.
Not really
Sorry, I am sure that I'm annoying but I really need to fix that problem.
My last try to solve ist is to send you the full code:

Can you find any mistakes?
I'm getting desperate...
Thanks a lot for your engagement!
I'n not really sure why that's happening. The only thing I can think of is XElement.Load() is causing the problem so here's how to use XDocument.Load() instead. I really hope this works for you because I'm out of ideas.
Code:
private void updateItemList()
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument xml = XDocument.Load(isoStream);
var items = from c in xml.Elements("Items").Elements("Item")
select new {
name = c.Element("Name").Value,
store = c.Element("Store").Value,
repeat = c.Element("Repeat").Value
};
foreach (var item in items)
{
ShowCaseEntry sce = new ShowCaseEntry(item.name, "Store: " + item.store, false);
ItemShowcase.Items.Add(sce);
}
isoStream.Close();
}
Same Error on this line:
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
Operation not permitted on IsolatedStorageFileStream.
I'm at the end of my motivation
I really tried everything, you really tried everything and I cannot find anything helpful to this error message..
Does anyone has an idea?
Does this line works for you?
Big Thanks to Ren13B till yet!
Attached is my working test project. Maybe it will help you.
If you are accessing the Isolated Storage from within a referenced assembly, you will need to access the IsolatedStorageFile for that assembly
Thanks for your reply but how to do that?
Hello,
i started to wrote my first WO7 applicatin.
I got following code:
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum; i++)
{
...
}
...
}
My Problem is that the content of the Button doesn't change to "Calculating". Even my Progressbar:
Code:
private void PbStep()
{
if (Pb1.Value == Pb1.Maximum)
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
else
{
Pb1.Value = Pb1.Value + 1;
}
}
It is wrapped in s loop, and the bar begins with 0 and then switsch to 100%, but i cant see the steps between.
I think i need a refresh command. in visual basic it is Me.Update();.
I tried many codes from google, but nothing helped. I hope some1 can help me.
many thank
Try
Code:
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Calculating...";
});
i did already try this. but now when i press the button, while calculation nothing happens, and after the calculation is finished, the button content changes to "calculating" and don't changes back to "start".
so i put the code in both parts and now i got the same as before. the button did not change its content
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
LblDuration.Text = "";
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Calculating...";
});
Pb1.Value = 0.0;
Pb1.Maximum = Max;
DateTime StartZeit = DateTime.Now;
for (int i = 0; i < Pb1.Maximum; i++)
{
PbStep();//Count Up PorgressBar
}
DateTime EndZeit = DateTime.Now;
TimeSpan GemesseneZeit = EndZeit - StartZeit;
LblDuration.Text = "Duration: " + GemesseneZeit.ToString();
Dispatcher.BeginInvoke(() =>
{
BtnStart.Content = "Start";
});
}
private void PbStep()
{
try
{
Pb1.Value = Pb1.Value + 1;
}
catch
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
}
But thank you for your help. any other ideas?
you really need to be looking at a background thread (background worker control may allow you do do this)
any tight loop like that will freeze the UI until the loop has finished
in the 'old days' a doevents within the loop itself would have been suffice but this is not good practice
HTH
Try this one, it does what you've trying to implement but using a correct way:
Code:
using System.Windows.Threading;
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
BtnStart.Content = "Calculating...";
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromMilliseconds(100);
timer.Tick += (_, __) =>
{
// Here is replacement of your PbStep()
Pb1.Value++;
};
timer.Start();
}
i got it now this way:
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
LblDuration.Text = "Duration: Calculating...";
BtnStart.Content = "Wait";
DateTime StartZeit = DateTime.Now;
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromMilliseconds(1);
timer.Tick += (_, __) =>
{
for (int i = 0; i < Pb1.Maximum; i++)
{
Pb1.Value++;
}
timer.Stop();
LblDuration.Text = "Duration: " + (DateTime.Now - StartZeit).ToString();
BtnStart.Content = "Start";
};
timer.Start();
}
It is half working. When i press Start, the button changes its content imediatly and after finishing the loop it return to its default content.
now i got 2 problems:
1. the progressbar isnt smooth jet
and the bigger one:
2. i wanted to create a benchmark programm an measure how long it takes to count a progressbar from 0 to 1million. now with the timer i dont have the real cpu speed because it is always waiting for the timer to tick. so the benchmark is sensless
@ cameronm:
I know the DoEvent command from other languages, but i wans able to use this in c#. i mainly programm in visual basic, cause this seems to be easy (In this case i would use Me.Update). I have heard from the Background worker, but never tried it. Maybe this can help.
I will do some google search and try to use the Background worker. I'll post again if i got new code
Thanks you all !
hello again
im now that far:
Code:
public partial class MainPage : PhoneApplicationPage
{
//Globale Variablen
private BackgroundWorker bw = new BackgroundWorker();
public int Max = 0;
// Konstruktor
public MainPage()
{
InitializeComponent();

bw.WorkerReportsProgress = true;
bw.WorkerSupportsCancellation = true;
bw.DoWork += new DoWorkEventHandler(bw_DoWork);
bw.ProgressChanged += new ProgressChangedEventHandler(bw_ProgressChanged);
bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted);
}
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
if (bw.IsBusy != true)
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
Pb1.Value = 0.0;
Pb1.Maximum = Max;
bw.RunWorkerAsync();
}
}
private void BtnStop_Click(object sender, System.Windows.RoutedEventArgs e)
{
if (bw.WorkerSupportsCancellation == true)
{
bw.CancelAsync();
}
}
private void bw_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
DateTime StartZeit = DateTime.Now;
//Failure by any deklarion
//like int i = 0 or BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum; i++)
{
if ((worker.CancellationPending == true)) //Abbruchbedingung
{
e.Cancel = true;
break;
}
else //Progressbedingung
{
PbStep();//Count Up PorgressBar
}
}
DateTime EndZeit = DateTime.Now;
TimeSpan GemesseneZeit = EndZeit - StartZeit;
LblDuration.Text = "Duration: " + GemesseneZeit.ToString();
BtnStart.Content = "Start";
}
private void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if ((e.Cancelled == true))
{
this.LblStatus.Text = "Canceled!";
}
else if (!(e.Error == null))
{
this.LblStatus.Text = ("Error: " + e.Error.Message);
}
else
{
this.LblStatus.Text = "Done!";
}
}
private void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.LblPercentage.Text = (e.ProgressPercentage.ToString() + "%");
}
private void PbStep()
{
try
{
Pb1.Value = Pb1.Value + 1;
}
catch
{
Pb1.Value = 0;
MessageBox.Show("Progressbar Overflow");
}
}
In the DoWork Function i receive an error when i try to set a variable like int i=0.
The Failure:UnauthorizedAccessException: Invalid cross-thread access
i followed this instruction: http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx
but there they did the same. why did i have the error?

The exception you've got show exactly what's wrong: you are trying to access GUI thread variables from another (BackgroundWorker) thread.
Use Dispatcher.Invoke as I recommended to you a few posts above.
thank you sensboston. id dont understand why, because i just have one bgworker, but now it works
Code:
private void BtnStart_Click(object sender, RoutedEventArgs e)
{
if (bw.IsBusy != true)
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
Pb1.Value = 0.0;
Pb1.Maximum = Max;
bw.RunWorkerAsync();
}
}
private void bw_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
DateTime StartZeit = DateTime.Now;
Dispatcher.BeginInvoke(() =>
{
LblDuration.Text = "";
BtnStart.Content = "Calculating...";
for (int i = 0; i < Pb1.Maximum; i++)
{
if ((worker.CancellationPending == true)) //Abbruchbedingung
{
e.Cancel = true;
break;
}
else //Progressbedingung
{
Pb1.Value = Pb1.Value + 1;
//PbStep();
}
}
DateTime EndZeit = DateTime.Now;
TimeSpan GemesseneZeit = EndZeit - StartZeit;
LblDuration.Text = "Duration: " + GemesseneZeit.ToString();
BtnStart.Content = "Start";
});
}
private void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.LblPercentage.Text = (e.ProgressPercentage.ToString() + "%");
}
Just my progressbar isnt running fluently. still just 0% (before calc) or 100% (after calc) and no steps between

It's simple, dear Watson: your code updating progress bar too fast, without delays needed for GUI updates

yep agree with this .. what you are actually doing in the loop is not enough for you to acutally see the progressbar update .. fast little things these phones of ours
yeah, this was the first i tryed, before posting in this forum.
delay() did not work in c#.
Application.DoEvents() should work if i can believe google, but visual studio says there is no definition for doevents().
So i used
Code:
Pb1.Value++;
System.Threading.Thread.Sleep(1);
after each progressbar.value++, but this either didnt work...
what is the secret?

1 millisecond will not be enough to slow it down either
Maybe try 1000 instead ..
something else i thought of too ..
you may want to think about your design
If a progress bar is going to just flash up and complete as what you are doing is too fast .. you need to think 'is a progress bar the right control to use'
if you are going to increase the amount of work your background thread is going to do then I would say keep the progress bar
If the background thread is going to be this quick always .. then maybe a label saying 'please wait' ... and then hide the label when done .. or something similar
i tried with 1000 ms but this progress bar isnt running.
@cameronm: i want to create a "benchmark app" where the cpu counts the progressbar to 1million and measures the time. the time measuring is working correctly. i just want to get a nice GUI with a running bar, like it runs when you download and install apps from the market.
i was very long googling and found commands like progressbar.PerfomStep(); like described here http://www.java2s.com/Code/CSharp/GUI-Windows-Form/ProgressBarinC.htm
this is also c#, but i cant perfom this command. did i miss some assembly, headers or so? or is it because im doint a windows phone form and that there are less command than in a normal windows application?
You want to make a Benchmark app and you actually used :System.Threading.Thread.Sleep(*int)...!
This is not Benchmarking.
Background Worker like any other ThreadTypeClass should report it's progress via the BackgroundWorker_ProgressChanged_Event(..args).
Inside the Event either u PerformStep() either you implement your own code logic.
If even after this the worker fills instanly like "cameronm" said above then consider making the backgroundworker's Job a bit heavier or leave the progressBar and even the seperated background thread Idea cause it is not Needed.
yes, i am not luck with using a sleep command
PerformStep() is not accepted by the compiler
so you mean just counting up is to "easy". what progress could be "heavier". now i understand what cameronm meant^^
in the evening i will try more difficult calculations like sqare and multiplication of integers. would that be heavy enough?
Typing from LG quantum
Try this: make your calculations in a for loop 1-100..at each loop make progressbar.value++ .
You should be calling ReportProgress and then updating the Progress Bar in the Progress Changed function.
See: http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx
@PG2G
the link you posted was exactly the source where i learned to implement the bw_worker. but with the command you told me i got an failure in the marked line (see source code comment). It says: InvalidOperationException: Operation has already been completed.

Hello friends!
I"m trying to build xposed module for educational purposes.
I want the module to:
1. Change the navigation bar color to green - this one works OK.
2. Change the navigation bar icons to custom icons i provide from my drawable resources - this one partially works, as described below.
The "home" button is changed, but the "recent apps" and "back" buttons didn't. Please see picture attached.
Can some one tell me why i can change the "home" button but not the "recent apps" and "back" buttons?
Any suggestion how to fix this?
module code:
Code:
import android.content.Context;
import android.content.res.XModuleResources;
import de.robv.android.xposed.IXposedHookInitPackageResources;
import de.robv.android.xposed.IXposedHookZygoteInit;
import de.robv.android.xposed.XposedBridge;
import de.robv.android.xposed.callbacks.XC_InitPackageResources.InitPackageResourcesParam;
import de.robv.android.xposed.callbacks.XC_LayoutInflated;
import android.graphics.Color;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout;
public class TweakNavigationBar implements IXposedHookZygoteInit, IXposedHookInitPackageResources {
private static String MODULE_PATH = null;
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
MODULE_PATH = startupParam.modulePath;
}
@Override
public void handleInitPackageResources(InitPackageResourcesParam resparam) throws Throwable {
if (!resparam.packageName.equals("com.android.systemui"))
return;
resparam.res.hookLayout("com.android.systemui", "layout", "navigation_bar", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
XModuleResources modRes = XModuleResources.createInstance(MODULE_PATH, liparam.res);
LinearLayout NavigationButtonsLayout = (LinearLayout) liparam.view.findViewById(
liparam.res.getIdentifier("nav_buttons", "id", "com.android.systemui"));
NavigationButtonsLayout.setBackgroundColor(Color.GREEN);
Context mContext = NavigationButtonsLayout.getContext();
ImageView backButton = (ImageView) liparam.view.findViewById(liparam.res.getIdentifier("back", "id", "com.android.systemui"));
ImageView homeButton = (ImageView) liparam.view.findViewById(liparam.res.getIdentifier("home", "id", "com.android.systemui"));
ImageView recentButton = (ImageView) liparam.view.findViewById(liparam.res.getIdentifier("recent_apps", "id", "com.android.systemui"));
//this also didn't work
//ImageView backButton = (ImageView) NavigationButtonsLayout.getChildAt(2);
//ImageView homeButton = (ImageView) NavigationButtonsLayout.getChildAt(3);
//ImageView recentButton = (ImageView) NavigationButtonsLayout.getChildAt(4);
recentButton.setImageDrawable(modRes.getDrawable(R.drawable.blue_button,null)); // didn't work!
homeButton.setImageDrawable(modRes.getDrawable(R.drawable.red_button,null)); // WORKS!
backButton.setImageDrawable(modRes.getDrawable(R.drawable,yellow_button,null)); // didn't work!
XposedBridge.log("start scan:");
for(int i=0; i< NavigationButtonsLayout.getChildCount() ; i++) {
View viewChild = (View) NavigationButtonsLayout.getChildAt(i);
XposedBridge.log(viewChild.toString());
if(viewChild instanceof ImageView)
XposedBridge.log("Child At " + i + " is instanceof ImageView" ) ;
}
}
});
}
}
Use this:
resparam.res.setReplacement(SYSTEM_UI, "drawable", "ic_sysbar_back_ime", modRes.fwd(R.drawable.n_back_down));
resparam.res.setReplacement(SYSTEM_UI, "drawable", "ic_sysbar_recent", modRes.fwd(R.drawable.n_recents));
resparam.res.setReplacement(SYSTEM_UI, "drawable", "ic_sysbar_back", modRes.fwd(R.drawable.n_back));
Note: SYSTEM_UI="com.android.systemui"
Using my method, i wasnt able to change the home button. But using your method, it did!
Thanks man!
