MainActivity(扩展活动)：

Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        startAnimation();
    }
});
 
 
public void startAnimation() {
    ImageView aniView = (ImageView) findViewById(R.id.imageView1);
    ObjectAnimator fadeOut = ObjectAnimator.ofFloat(aniView,"alpha",0f);
    fadeOut.setDuration(2000);
 
    ObjectAnimator mover = ObjectAnimator.ofFloat(aniView,"translationX",-500f,0f);
    mover.setInterpolator(new TimeInterpolator() {
        @Override
        public float getInterpolation(float input) {
            Log.v("MainActivity","getInterpolation() " + String.format("%.4f",input));
            return input;
        }
    });
    mover.setDuration(2000);
 
    ObjectAnimator fadeIn = ObjectAnimator.ofFloat(aniView,0f,1f);
    fadeIn.setDuration(2000);
 
    AnimatorSet animatorSet = new AnimatorSet();
 
    animatorSet.play(mover).with(fadeIn).after(fadeOut);
    animatorSet.start();
}
