Fragment中使用ViewFlipper在嚴格模式下抛出android.app.IntentReceiverLeaked

今天遇到一個bug:IntentReceiverLeaked, 是在嚴格模式下報的：

12-20 01:04:17.503 E/StrictMode(14464): android.app.IntentReceiverLeaked: Activity com.video.test.DetailActivity has leaked IntentReceiver [email protected] that was originally registered here. Are you missing a call to unregisterReceiver()?

開始以為是Activity中的BroadcastReceiver沒有調用unregisterReceiver，排查了代碼發現都正常調用了。那應該是其他的問題了， 我試着檢索了ViewFlipper，發現DetailActivity中有個Fragment用到了ViewFlipper， 網上查了下資料：

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

大多是說重載onDetachedFromWindow，并在其中加入stopFlipping;或許我的情況與之不同，依然無效；

解決：重載Activity的onDetachedFromWindow在其中加入

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

即可

由于我使用的是Fragment， 後來在重載Fragment的onDetach：

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

發現OK了。
