我正在尝试ActivityGroup在另一个中运行嵌入
ActivityGroup。（例如：一个ActivityGroup里面的 a TabActivity）
这似乎可以正确显示，但是当我尝试显示模态框（如AlertDialog.
TabActivity
Tab1Tab2MyGroupActivityChildActivity1
ChildActivity2
如果 childActivity1 或 2 尝试显示一个DialogBox我得到这个
exception：
ERROR/AndroidRuntime(2449):
android.view.WindowManager$BadTokenException: Unable to add window --
token android.app.LocalActivityManager$LocalActivityRecord@43424620 is
not valid; is your activity running?
如果有人知道请回复...
这是我的对话框代码
final Dialog dialog = new Dialog(EditDeleteReqCardList.this);
dialog.setContentView(R.layout.customdialougbox);
dialog.setTitle("Request Card - "+reqid);
// set the custom dialog components - text, image and button
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Do You Want to Delete This request Card ?");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.dialougimage);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
Button cancelbutton = (Button) dialog.findViewById(R.id.cancel);
dialogButton.setText("Yes");
dialog.show();
