Is there a way to change android.R.layout.simple_list_item_1, to my custom layout?

Everytime i try to change to custom layout everything crashes, i dont know how to do it not losing dialog window, because text i am reading from is in my custom dialog. I know that maybe creating new adapter class can solve the problem but i want to try another way.

Use CTRL + Left click on android.R.layout.simple_list_item_1 to open it.
Copy the contents to your own XML layout file, and edit it as your wish.
Change
android.R.layout.simple_list_item_1
To
R.layout.your_layout

I am new to android app development, so this may be easy for you. I have searched this forum before I posted so please take a look before marking it as duplicate. I am not declaring static variables in the updatestandard method. Here is my program:

so in eclipse it says in the update standard lines that the variables are not used the tenPercentTotal,fifteenPercentTotal and twentyPercentTotal idk why it says that they are used in the next lines below it pls help this exact program worked before i right clicked my project and selected export android app option that messed up many things idk what happened.

You're spelling their names out in the formatting strings instead of actually using them as arguments in the String#format() method calls.

Eclipse is not wrong (maybe refresh project + Validate if hes outdated).
Assigning values to variable does not count as usage.

Android thread test does not work

Hi I'm beginner with android development and I have a problem with my following test code:

TestCLas.java:
package com.tutorial.sample;
import android.content.Context;
import android.widget.TextView;
import android.widget.Toast;
public class TestClass{
private boolean stopIter = false;
private TextView txtV = null;
private int count = 0;
private Context ctx = null;
public TestClass(Context ct, TextView tv) {
// TODO Auto-generated constructor stub
txtV = tv;
stopIter = false;
count = 0;
ctx = ct;
}
public boolean isStop() { return stopIter; }
public void Stop()
{
Toast.makeText(ctx, "stop the test" , Toast.LENGTH_LONG).show();
count = 0;
txtV.setText(Integer.toString(count));
stopIter = true;
}
public void DoSomeThing(){
txtV.setText(Integer.toString(count));
}
}
I want to manage my activity's viewer with threads. I launch a thread in order to modify TextView's text (each sec) when the start button is clicked and stop it when stop button is clicked. But it does not work, it crashes without any exception. Can someone help me please?

wait(1000);
This should NEVER be done on the UI thread.
The UI thread is the one that update the GUI, and communicates with Android to say everything is working as expected. When you have a thread delay on the UI thread, the message to and from the android system get held back, and you app appears to the system as if it has crashed.

How to set image as wall paper in viewpager app?

Edited code after following this link ...Set wallpaper from ViewPager .I developed simple viewpager app along with the background music. However, I want to modify my app so that image chosen by user will give them option to set as wallpaper....I don't want to implement any buttons in my app. User should be able to just touch the image , which will give them option to set as wallpaper...
I am getting error at this code curruntPosition=arg0;. It says "Current position cannot be resolve to a variable". I don't know what it mean ...
Following are my codes...
Mainactivity.java

return imageView;
}

public void destroyItem(ViewGroup container, int position, Object object) {

}
}
I just start with programming, so please give some explanations, or it will be great if you provide some codes .

First add this Permission to the Manifest
<uses-permission android:name="android.permission.SET_WALLPAPER">
Now for some code.
imageview.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
WallpaperManager myWallpaperManager
= WallpaperManager.getInstance(context);
try {
myWallpaperManager.setResource(GalImages[position]);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
Explantion : This will set that the Image will be clickable , when the image is clicked it will set the phone Wallpaper with the selected drawable.
getApplicationContext()
is the Context from the Activity.
This changes will take place inside the Adapter.
Activity
add this variable
int currentPosition;

unreachable code, counter = 0

hello,
i just started following tutorial to make android apps with eclips.
Now I get this error unreachable code at the line with "counter = 0"
I think it's has to do something with the line "return true" because, when i remove that the error is gone but then i get other errors :s, does someone know what the problem is here?
Thanks in advance

Any code after the return will never be executed. Therefore you get unreachable code.
Put return at the end of the method
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.startingpoint, menu);
counter = 0;
...
return true;
}
