您好我正在开发一个包含四个标签的TabBar应用程序。每当打开应用程序时，第一个选项卡都会被选中。在第一个选项卡中，我正在加载一个由{5}内容（一些标签和文本框）组成的WebView。在TextBoxes中输入一些数据并能够导航到另一个WebView后，在这个WebView中我有一个微调器，即一个HTML微调器。但每当我点击该微调器时，我都会得到以下Exception：
**02-15 15:16:56.081: E/AndroidRuntime(6133): android.view.WindowManager$BadTokenException: Unable to add window -- token android.app.LocalActivityManager$LocalActivityRecord@449e45c8 is not valid; is your activity running?

答案 0 :(得分：2)
您使用的是活动组吗？
如果您正在使用try来夸大布局而不是setcontentview（yourlayout）
View viewToLoad = LayoutInflater.fromContext(this.getParent()).inflate(R.layout.rdcmobile,null);
this.setContentView(viewToLoad)
...find views from viewToLoad
mWebView = (WebView) viewToLoad.findViewById(R.id.webview);
