当前回答

当我在AsyncTask中使用ProgressDialog时，这种情况发生在我身上。实际上，我在onPostExecute中使用hide()方法。基于@Alex Volovoy的答案，我需要使用遣散()与ProgressDialog删除它在onPostExecute和它完成。

progressDialog.hide(); // Don't use it, it gives error

progressDialog.dismiss(); // Use it

其他回答

当您尝试在活动有效完成后显示警报时，会出现“活动已泄漏最初添加的窗口…”错误。

AFAIK，你有两个选择:

重新考虑登录alert:在实际退出activity之前调用对话框上的dismiss()。将对话框放在不同的线程中，并在该线程上运行它(与当前活动无关)。

解决方案是在退出Activity之前在view .java:183中创建的对话框上调用dismiss()，例如在onPause()中。所有的窗口和对话框应该在离开一个活动之前关闭。

当您退出活动后试图显示对话框时，会出现此问题。

我只是通过写下下面的代码解决了这个问题:

@Override
public void onDestroy(){
    super.onDestroy();
    if ( progressDialog!=null && progressDialog.isShowing() ){
        progressDialog.cancel();
    }
}

基本上，从哪个类你开始progressDialog，覆盖onDestroy方法，这样做。它解决了“活动已泄漏窗口”的问题。

我在AlertDialog上错误地调用hide()而不是dismiss()触发了这个错误。

窗口泄漏异常有两个原因:

1)当Activity上下文不存在时显示对话框，为了解决这个问题，你应该只显示你确定Activity存在的对话框:

if(getActivity()!= null && !getActivity().isFinishing()){
        Dialog.show();
}

2)对话框不适当解散，解决使用以下代码:

@Override
public void onDestroy(){
    super.onDestroy();
    if ( Dialog!=null && Dialog.isShowing() ){
        Dialog.dismiss();
}
}
