I have added some images statically and add them in HorizontalScrollView.There is a button for set wallpaper now I want to choose image from that and want to set wallpaper.please help me out.

Answer 1

u may need to setOnClickListener() on all of your ImageView, i would suggest you added your Images programmatically, that will make your onClick event handling easier.

as for setting up wallpaper, you need to declare android.permission.SET_WALLPAPER permission at your manifest file. And the following code will set Bitmap bmp as wallpaper

getApplicationContext().setWallpaper(bmp);
