Usage

From source file:Main.java

public static void hide(final View view, final boolean makeInvisible) {
    if (Build.VERSION.SDK_INT >= 11) {
        final Animation animation = new Animation() {
            @TargetApi(11)/*from  www . ja  va  2 s  .co  m*/
            @Override
            protected void applyTransformation(final float interpolatedTime, final Transformation t) {
                view.setAlpha(1.f - interpolatedTime);
            }
        };

        animation.setDuration(ANIMATION_DURATION);
        // return animation;
        view.startAnimation(animation);
    } else {
        view.setVisibility(View.INVISIBLE);
