android - 窗口管理器 $BadTokenException : Unable to add window -- token in popup window

Question

我根据 following link 制作了自定义弹出对话框这是我的对话。

我有按钮列表来显示弹出窗口。当我单击这些按钮时，将显示此对话框。我的问题有点奇怪。有时当我在对话框中选择笔记编辑文本时，我得到了 WindowManager$BadTokenException。

不知道为什么？我没有太多改变编码。我在 popupwindow 构造函数中添加了 mWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE) 以在键盘上方显示对话框。如果我在模拟器上运行，没有问题。在真实设备中，我遇到了异常。有什么想法吗？

在我这样实现的按钮监听器中

 if(dialogNote == null) {
  dialogNote = new QuickActionNote(AddNewNoteActivity.this);
 }
 dialogNote.show(btn);

谢谢。

此问题是由于您的手机键盘启用了自动提示，如果您尝试单击具有预填充数据的编辑文本。使用 android:inputType="textNoSuggestions"可以解决您的问题。
