How to display a button in random screen position

For the second screen use absolute layout, but the button on X=0, Y=0

Once your second screen gets activated. onCreate Method

Button button = (Button)findViewById(R.id.my_button);
AbsoluteLayout.LayoutParams absParams = 
    (AbsoluteLayout.LayoutParams)button.getLayoutParams();

DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int width = displaymetrics.widthPixels;
int height = displaymetrics.heightPixels;


Random r = new Random();

absParams.x =  r.nextInt(width ) ;
absParams.y =  r.nextInt(height );
button.setLayoutParams(absParams);

EDIT User wanted to know how to write AbsoluteLayout

<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
  <Button
        android:id="@+id/my_button"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_x="0dp"
        android:layout_y="0dp"
        android:text="Yes" />
</AbsoluteLayout>

    displaymatrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displaymatrics);

    textview.setOnTouchListener(new View.OnTouchListener(){

        Random R = new Random();
        float dx = R.nextFloat() * displaymatrics.widthPixels;
        float dy = R.nextFloat() * displaymatrics.heightPixels;

        public boolean onTouch(View view, MotionEvent event){

            if(event.getAction() == MotionEvent.ACTION_DOWN){

                        view.animate()
                                .x(dx)
                                .y(dy)
                                .setDuration(0)
                                .start();
            }
            return true;
        }
    });

AbsoluteLayout is now deprecated, You can move a View(when it's touched) in random screen position this way easily.
