Android Alpha动画非常慢

Question

I have an app that show a SurfaceView that shows a camera preview, and on top of that a couple other UI elements (buttons). Basically, the user inputs their code, i FadeOut the UI leaving the normal preview and take a picture which is later uploaded. This all worked fine on an older tablet, however, switching to an XPERIA Z2 tablet this thing became VERY SLOW when calling view.animate(); I have noticed that the tablet starts OpenGL, (I didn't notice that on the old tablet).

: EGL 1.4 QUALCOMM build: () OpenGL ES Shader Compiler Version: E031.24.00.06 Build Date: 02/12/14 Wed Local Branch: au090 Remote Branch: Local Patches: Reconstruct Branch:

Now this might be the problem. How do I turn it off? I will paste the animation here anyway:

public static Animation fadeOut() {

    Animation fadeOut = new AlphaAnimation(1, 0);

    fadeOut.setInterpolator(new DecelerateInterpolator()); //add this

    fadeOut.setDuration(500);

    return fadeOut;
}

Any ideas?

Well, if anyone expiriences something like this, the problem was I was setting the animation on the view and then calling view.animate(). Using view.startAnimation(Animation) is working allright!
