Setting wallpaper using onclick event of a button has no effect

Question

I'm following the tutorial trying to set the wallpaper using onclick event of a button.

My code for that is,

private OnClickListener startListener = new OnClickListener(){

    public void onClick(View v){

        setBg();}

    public void setBg(){
        WallpaperManager myWallpaperManager
         = WallpaperManager.getInstance(getApplicationContext());
        try {
         myWallpaperManager.setResource(R.drawable.shrek);
        } catch (IOException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
        }

       }

Also i've set the permission SETWALLPAPER.

But when i click, Nothing happens.

whats the problem here?

Answer 1

In this tutorial, he uses the OnClickListener a bit different:
buttonSetWallpaper.setOnClickListener(new Button.OnClickListener(){....

Try this, should work:

start.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) { 
    WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext());
    try {
     myWallpaperManager.setResource(R.drawable.shrek);
    } catch (IOException e) {
     e.printStackTrace();
    }
   }});

EDIT: Of course you can also just call your method in OnClick instead of handling it directly
