Question

我在下面添加了我的代码。同步按钮后不显示列表视图项目。我正在使用相对布局

<Button
    android:id="@+id/button_sync"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/button_sync" />

<ListView
    android:id="@+id/company_factory_truck_list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/button_sync"
    android:divider="@android:color/transparent"
    android:dividerHeight="10.0sp"
    >

</ListView>

此代码同时显示按钮和列表视图

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <Button
        android:id="@+id/button_sync"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/button_sync" />

    <ListView
        android:id="@+id/company_factory_truck_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/button_sync"
        android:divider="@android:color/transparent"
        android:dividerHeight="10.0sp"
        >

    </ListView>

</RelativeLayout>
