Question

I am trying to rotate an arrow to point to some specific location

  float bearing = myLoc.bearingTo(mecca);
      RotateAnimation rotate = new RotateAnimation(0, bearing, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
      arrow.setAnimation(rotate);
      rotate.start();

However it rotates and within less than one second it comes to its original place. How can i make it rotate like a compass.

Another simple way to rotate an imageView :

Matrix matrix=new Matrix();
imageView.setScaleType(ScaleType.MATRIX);   //required
matrix.postRotate((float) angle, pivX, pivY);
arrow.setImageMatrix(matrix);
