弹出窗口关闭服务
我试图在 InputMethodService 中显示一个 PopupWindow，但是当我使用此代码显示它时：
LayoutInflater inflater = ( LayoutInflater ) getSystemService( LAYOUT_INFLATER_SERVICE );
pw = new PopupWindow(
inflater.inflate(R.layout.info_dialog, null, false), 320, 480, true);
pw.showAtLocation(mInputView, Gravity.CENTER, 0, 0);
窗口将在关闭我的 InputMethodService 之前短暂闪烁。
我从 LogCat 得到的错误就是这样的：
12-21 15:22:20.530: E/InputMethodService(4075): Unexpected null in startExtractingText : mExtractedText = null, input connection = com.android.internal.view.InputConnectionWrapper@40a60150
有人以前见过这个或者知道如何处理它吗？
I am trying to show a PopupWindow within an InputMethodService, but when I show it using this code:
LayoutInflater inflater = ( LayoutInflater ) getSystemService( LAYOUT_INFLATER_SERVICE );
pw = new PopupWindow(
inflater.inflate(R.layout.info_dialog, null, false), 320, 480, true);
pw.showAtLocation(mInputView, Gravity.CENTER, 0, 0);
the window will flash briefly before closing my InputMethodService.
The error I get from LogCat is just this:
12-21 15:22:20.530: E/InputMethodService(4075): Unexpected null in startExtractingText : mExtractedText = null, input connection = com.android.internal.view.InputConnectionWrapper@40a60150
Has anyone seen this before or know how to deal with it?

您不使用 AlertDialog/Dialog 是否有任何真实原因？为什么根据您的代码，对话框适合这个。它将弹出在用户屏幕的中间，您可以填充那里的视图。而且，您甚至可以为其设置监听器！
Is there any REAL reason why you aren't using an AlertDialog/Dialog? Why based on your code, a dialog would suite this. It will popup right in the middle of the user's screen and you can populate the view that is there. And, you can even set listeners to it!
