当前回答

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

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)。

也许你在activity中使用了findViewById而不是dialog。findViewById，然后在空实例上设置OnClickListener，这可能会导致原始错误。

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。

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

通常这个问题是由于进度对话框发生的:你可以在你的活动中使用以下任何一种方法来解决这个问题:

 // 1):
          @Override
                protected void onPause() {
                    super.onPause();
                    if ( yourProgressDialog!=null && yourProgressDialog.isShowing() )
                  {
                        yourProgressDialog.cancel();
                    }
                }

       // 2) :
         @Override
            protected void onDestroy() {
                super.onDestroy();
                if ( yourProgressDialog!=null && yourProgressDialog.isShowing()
               {
                    yourProgressDialog.cancel();
                }
            }
