ImageView will reset to original state after rotating?

Possible Duplicate: Android: Animation Position Resets After Complete I'm using `RotateAnimation` to rotate an `ImageView`. The code is simple: ``` this.button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Animation ani = new RotateAnimation( 0, /* from degree*/ 30, /* to degree */ Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); ani.setDuration(1000); imageView.startAnimation(ani); } }); ``` You can see I want the imageView rotate 30 degree. It works, but when rotating is done, the image go back to the original state, the same position and degree before rotating. I want to fix ImageView at last Animation position i.e want to fix the image tilted by 30 degree. How to fix it?
