ApiDemo学习 setEmptyView的用法

其实应该吧emptyView放在 listView的下面

<!--
    The frame layout is here since we will be showing either
    the empty view or the list view.
    -->

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="0dip"
        android:layout_weight="1" >

        <!--
             Here is the list. Since we are using a ListActivity, we
             have to call it "@android:id/list" so ListActivity will
             find it
        -->

        <ListView
            android:id="@android:id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:drawSelectorOnTop="false" />

        <TextView
            android:id="@+id/empty"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="@string/list_8_no_photos" />
    </FrameLayout>

然后list.setEmptyView(findViewById(R.id.empty));

list有数据的时候 textView不会显示 否则就会显示那个 空View
