Fragment中使用ViewFlipper在严格模式下抛出android.app.IntentReceiverLeaked

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): android.app.IntentReceiverLeaked: Activity com.video.test.DetailActivity has leaked IntentReceiver android.widget.ViewFlipper$1@42b37fc0 that was originally registered here.

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：

(http://www.eoeandroid.com/thread-159069-1-1.html)

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() {        super.onDetach();        if(viewFlipper!=null){            //防止android.app.IntentReceiverLeaked            viewFlipper.stopFlipping();        }    }

发现OK了。
