Question

I’m trying to make a app that allows you to drag shapes around. It works fine on smart phones, but not on my Acer a500 tablet

When I get the height by calling

ih=getWindowManager().getDefaultDisplay().getHeight()-25;

I get a value thats only 1/3 of what it should be, thus I can only drag the sahpes 1/3 the way down. If the tablet is horizonatl it goes 1/2 way down.

Why is this methed returning the wrong values for the height on my tablet??

public class cPlay extends  cBase  implements OnClickListener {
/** Called when the activity is first created. */
   @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
  //      setContentView(R.layout.play);


        int w=getWindowManager().getDefaultDisplay().getWidth()-25;
        int h=getWindowManager().getDefaultDisplay().getHeight()-25;

        BallView ballView=new BallView(this,w,h);
        setContentView(ballView);
   } // end function

   public void onClick(View v) {
       finish();

       } // end function

} // end class

Try this:

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