img5.setImageResource(R.drawable.crown);
img5.setOnTouchListener(new View.OnTouchListener() {
float x,y=0.0f;
boolean moving=false;
@Override
public boolean onTouch(View arg0, MotionEvent arg1) {
// TODO Auto-generated method stub
switch(arg1.getAction()){
case MotionEvent.ACTION_DOWN:

break;
case MotionEvent.ACTION_MOVE:
if(moving){

x=arg1.getRawX()-img5.getWidth()/2;
