                }       
        return null;

    }

    @Override
    protected void onPostExecute(Integer result) {
        super.onPostExecute(result);
        pd.dismiss();

}

错误是： android.view.WindowManager $ BadTokenException：无法添加窗口 - 令牌android.app.LocalActivityManager $ LocalActivityRecord@40e16110无效;你的活动在运行吗？

问题

我通过另一个tabhost调用活动。它只加载视图.Web服务和按钮不起作用。当我点击上面显示的按钮时出错。帮我继续下去..

参考： http://www.gamma-point.com/content/android-how-have-multiple-activities-under-single-tab-tabactivity

否则不推荐使用ActivityGroup ..，我现在应该使用什么..

Answer 1

对于您发布的内容，您似乎根本不需要使用ActivityGroup。只需从Feedback课程延长Activity即可。例如：

public class Feedback extends Activity

tabhost组活动不起作用（不建议使用）
