Question

我一直在尝试将三种不同的活动分别添加到不同的标签中...... 一项活动是启动蓝牙发现和选择蓝牙设备进行配对

第二个将是基于蓝牙的鼠标垫

我正在关注许多在线资料..基本上这一个http://www.androidhive.info/2011/08/android-tab-layout-tutorial/

但不知怎的，它显示了这个错误

正如它在这里所说：

11-08 13：41：24.714：E / AndroidRuntime（22886）：引起：java.lang.RuntimeException：你的TabHost必须有一个FrameLayout，其id属性是'android.R.id.tabcontent'

您缺少具有正确ID的frameLayout，因此请查看我的代码并尝试执行相同操作。希望它有所帮助：）

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rootview"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<TabHost
    android:id="@+id/mainTabHost"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
     >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
           >
        </TabWidget>

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >

                 <include layout="@layout/view_offer_tab1" />
                 <include layout="@layout/view_offer_tab2" />


        </FrameLayout>
    </LinearLayout>
</TabHost>

选项卡式活动无效
