出现这种情况很可能是因为设置了animation，并且调用了setFillAfter(true)，这就会导致setVisibility无效，只需要调用一下clearAnimation()方法或者去掉setFillAfter(true)语句即可。
实验证明只要在setVisibility之前设置View的mCurrentAnimation为null就可以，因此调用setAnimation(null)也是可以的。从源码来看setFillAfter为false时也会间接导致调用clearAnimation，而clearAnimation在这里使setVisibility有效的原因也是置mCurrentAnimation为null了。
setFillAfter为false时间接导致clearAnimation：
而mCurrentAnimation使GONE无效的初步分析很可能是下面的代码造成：
在dispatchDraw子View的时候，尽管不为VISIBLE，由于是||的关系，也会导致drawChild被调用。而drawChild的代码如下：
/**
* Draw one child of this View Group. This method is responsible for getting
* the canvas in the right state. This includes clipping, translating so
* that the child's scrolled origin is at 0, 0, and applying any animation
* transformations.
*
* @param canvas The canvas on which to draw the child
* @param child Who to draw
* @param drawingTime The time at which draw is occurring
* @return True if an invalidate() was issued
*/
protected boolean drawChild(Canvas canvas, View child, long drawingTime) {
return child.draw(canvas, this, drawingTime);
}
