Question

每当我从/向MainActivity按回来时，都会收到此错误消息。该应用程序不会崩溃，但此消息将显示在logcat中。我搜索过这个问题，但大多数都与解雇对话有关。但我的情况是我没有在MainActivity上显示对话框。

我也有这个问题。做了一件事，它对我有用。

PullToRefreshLayout （扩展RelativeLayout）类实际上是将RelativeLayout动态添加到主活动中。我不明白它的一切。但是，我可以告诉你的一件事是，当用户退出主活动时，需要销毁RelativeLayout。

销毁相对布局实际上已经由PullToRefresh处理，但在我的情况下在某些时候失败了。我不得不在我的主要活动的onDetachedFromWindow（）中手动销毁RelativeLayout视图。

我在我的库中修改了 PullToRefreshLayout.java 并添加了：

public void manuallyDetachFromWindow(){
    onDetachedFromWindow();
}

在 MainActivity.java 中，我添加了以下代码：

public static WeakReference<PullToRefreshLayout> wrefMPullToRefreshLayout;
...

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    wrefMPullToRefreshLayout = new WeakReference<PullToRefreshLayout>(new PullToRefreshLayout(this));

}

@Override
public void onDetachedFromWindow() {
    super.onDetachedFromWindow();
    try{
         MainActivity.wrefMPullToRefreshLayout.get().manuallyDetachFromWindow();
    }catch(NullPointerException e){

    }
}

希望这有帮助。
