java - Android:alertdialog中的微调器崩溃

Question

我在Alertdialog中有旋转器。如果显示alertdialog并且屏幕方向已更改-一切正常。 Alertdialog仍显示。但是，如果微调器处于打开状态，并且屏幕方向发生了变化，则应用程序将崩溃，并且视图未附加到窗口管理器。我在onDestroy中尝试了alertdialog.dismiss（），但未成功。有任何想法吗？

LayoutInflater li = LayoutInflater.from(ScrollingActivity.this);
View promptsView = li.inflate(R.layout.popup_layout, null);
AlertDialog.Builder alertDialogBuilder = new 
AlertDialog.Builder(ScrollingActivity.this, R.style.MyAlertDialogStyle);

alertDialogBuilder.setView(promptsView);

alertDialogBuilder.setTitle(R.string.def_recipe_lang);
alertDialogBuilder.setIcon(R.drawable.ic_language_orange_24px);
// create alert dialog
alertDialog = alertDialogBuilder.create(); 
alertDialog.show();
alertDialog.setCanceledOnTouchOutside(false);

Answer 1

“我在onDestroy中尝试过alertdialog.dismiss（）”，----是正确的，但是您必须在Onpause（）中而不是在Ondestroy（）中进行。

毁灭将在屏幕被破坏时执行，而不是在方向改变时执行。

尝试此操作，如果遇到错误，请发布代码和android Monitor错误以获取适当的答案。
