I want to change this image:
I have researched how I can do this, but the only thing is:
Obviously I'm looking bad, What can I do to achieve my goal ???
Thanks in advance.
You can use the WallpaperManager class:
Button buttonSetWallpaper = (Button)findViewById(R.id.set);
ImageView imagePreview = (ImageView)findViewById(R.id.preview);
imagePreview.setImageResource(R.drawable.five);
buttonSetWallpaper.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View arg0) {
WallpaperManager myWallpaperManager
= WallpaperManager.getInstance(getApplicationContext());
try {
myWallpaperManager.setResource(R.drawable.five);
} catch (IOException e) {
e.printStackTrace();
}
}
});
and you must add to your file AndroidManifest.xml the permission to make the change:
<uses-permission android:name="android.permission.SET_WALLPAPER"/>
