public class MainActivity extends Activity {

       int windowwidth;
       int windowheight;

       private LayoutParams layoutParams;

       @Override
       public void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.activity_main);

              windowwidth = getWindowManager().getDefaultDisplay().getWidth();
              windowheight = getWindowManager().getDefaultDisplay().getHeight();
              final ImageView img = (ImageView) findViewById(R.id.imageView1);

              img.setOnTouchListener(new View.OnTouchListener() {

                     @Override
                     public boolean onTouch(View v, MotionEvent event) {
                           LayoutParams layoutParams = (LayoutParams) img
                                         .getLayoutParams();
                           switch (event.getAction()) {
                           case MotionEvent.ACTION_DOWN:
                                  break;
                           case MotionEvent.ACTION_MOVE:
                                  int x_cord = (int) event.getRawX();
                                  int y_cord = (int) event.getRawY();

                                  if (x_cord > windowwidth) {
                                         x_cord = windowwidth;
                                  }
                                  if (y_cord > windowheight) {
                                         y_cord = windowheight;
                                  }

                                  layoutParams.leftMargin = x_cord - 25;
                                  layoutParams.topMargin = y_cord - 75;

                                  img.setLayoutParams(layoutParams);
                                  break;
                           default:
                                  break;
                           }
                           return true;
                     }
              });
       }
}
