在Activity中定义方法(dialogClicked).并修改 TestDialog 如下代码:

Define the method (dialogClicked) in Activity. And modify TestDialog like the following code:

public class TestDialog extends Dialog {
 Context mContext;
 public TestDialog(final Context context)
 {

  super(context);
  mContext=context;
 }

 @Override
 protected void onCreate(final Bundle savedInstanceState)
 {
  super.onCreate(savedInstanceState);
  LinearLayout ll=(LinearLayout) LayoutInflater.from(mContext).inflate(R.layout.dialog, null);
  setContentView(ll); 
 }
}

我认为它有效:)
