Animate a Chat Head

Question

I am developing an app to show chat head.
I have to implement translate animation on chat head, but it is not animating.

TranslateAnimation trans = new TranslateAnimation(0, 
    windowManager.getDefaultDisplay().getWidth() / 2, 0, 
    windowManager.getDefaultDisplay().getHeight());
trans.setFillAfter(false);
trans.setDuration(1000);
view.setAnimation(trans);

trans.setAnimationListener(new AnimationListener() {
    @Override
    public void onAnimationStart(Animation animation) {

    }

    @Override
    public void onAnimationRepeat(Animation animation) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onAnimationEnd(Animation animation) {

    }
});

Answer 1

You have to start animation on view:

view.startAnimation(trans);
