Question

因此，出于某种原因，在我的Samsung Galaxy S2（Android版本4.0.4）尝试从RelativeLayout中删除ImageView时，我得到了一个NPE。这是运行的代码行

mainView.removeView(someImageView)

然而，在我的Galaxy Nexus（Android版本4.1.1）上，它甚至没有打嗝。我在下面发布了NPE。这不是删除ImageView的正确方法吗？基本上我完成了图像，我不再需要它了。任何想法或想法都会很棒。

编辑：我认为这与问题没有任何关系，但是在翻译动画的“onAnimationEnd”方法中删除了这个。

尝试将imageView的可见性设置为GONE，如：

someImageView.setVisibility(View.GONE);

删除ImageView会导致某些手机崩溃
