I get a result similar to http://i3.6.cn/cvbnm/e1/71/e9/19008bd7258eaf858be73dc6431b1f8b.jpg. I want to get two tabs; could you help me?

You need to use TabWidget : http://developer.android.com/reference/android/widget/TabWidget.html or http://developer.android.com/guide/tutorials/views/hello-tabwidget.html to show the buttons for the tabs if that's what you are looking for...

i answer my question: tabWidget is wrong and add LinearLayout:

<TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent">
<LinearLayout android:orientation="vertical"
    android:layout_width="fill_parent" android:layout_height="fill_parent">

    <TabWidget android:id="@android:id/tabs"
        android:layout_width="fill_parent" android:layout_height="wrap_content" />
      <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"  >
        <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/main">
            <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1"/>
            <TextView android:id="@+id/empty" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center" android:text="Loading"/>

        </LinearLayout>
        <RelativeLayout  android:id="@+id/mainlayout" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content">
            <com.google.android.maps.MapView android:id="@+id/mapview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:clickable="true" android:apiKey="0Ua9BENcUvNKEom7wvjrrtlCVIeJ9SNYAbLAkJA"/>
        </RelativeLayout>
      </FrameLayout>
  </LinearLayout>
