当前回答

这不是问题的答案，但与主题相关。

如果活动在清单中定义了属性

 android:noHistory="true"

然后在执行onPause()后，活动的上下文将丢失。所有使用这个context的视图都会给出这个错误。

其他回答

尝试下面的代码，它将在任何时候工作，你将解散进度对话框，它将看到它的实例是否可用。

try {
        if (null != progressDialog && progressDialog.isShowing()) {
            progressDialog.dismiss();
            progressDialog = null;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

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();
}
}

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。

  if (mActivity != null && !mActivity.isFinishing() && mProgressDialog != null && mProgressDialog.isShowing()) {
        mProgressDialog.dismiss();
    }

我最近也遇到了同样的问题。

这个问题背后的原因是在对话框被解散之前活动被关闭了。上述情况的发生有多种原因。上面的帖子中提到的也是正确的。

我陷入了一种情况，因为在线程中，我调用了一个抛出异常的函数。因此，窗口被关闭，因此出现异常。
