Fragment中使用ViewFlipper在严格模式下抛出

今天遇到一个bug:IntentReceiverLeaked, 是在严格模式下报的：

12-20 01:04:17.503 E/StrictMode(14464): : Activity  has leaked IntentReceiver $1@42b37fc0 that was originally registered here. Are you missing a call to unregisterReceiver()?

开始以为是Activity中的BroadcastReceiver没有调用unregisterReceiver，排查了代码发现都正常调用了。那应该是其他的问题了， 我试着检索了ViewFlipper，发现DetailActivity中有个Fragment用到了ViewFlipper， 网上查了下资料：

(/)

大多是说重载onDetachedFromWindow，并在其中加入stopFlipping;或许我的情况与之不同，依然无效；

解决：重载Activity的onDetachedFromWindow在其中加入

if(mViewFlipper != null){
    mViewFlipper .onDetachedFromWindow();
}
即可


由于我使用的是Fragment， 后来在重载Fragment的onDetach：

@Override
    public void onDetach() {
        ();
        if(viewFlipper!=null){
            //防止
            ();
        }
    }

发现OK了。
