Question

我在一项活动中运行了4个后台任务。但我在一个活动中遇到错误 pDialog.show（）。我无法理解。对于某些活动，我遇到了同样的问题，但我删除了进度对话框，因为这些是中等优先级，但这个我需要高优先级。这是我的错误。可以告诉我如何解决这个错误。

Answer 1

如果您在程序中使用Handler或AsyncTask，请使用Thread来显示对话框。如果问题仍然存在，请尝试发布您的代码以获得进一步的帮助：）

Answer 2

在退出活动之前，应关闭所有进度对话框。您可能忘记关闭progressDialog。

在onPostExecute（）方法中关闭它

    pDialog.dismiss();
