Question

我的导航抽屉使用listview，因此我将listview作为抽屉菜单。现在在我的项目中，我想DIY将列表视图更改为textview，imageview。这是抽屉主要布局：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/wallpaper01"
    android:id="@+id/drawer_layout">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/main_content">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="luis"/>
    </RelativeLayout>
    <ListView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/lv_sliding_menu"
        android:background="@drawable/wallpaper01"
        android:choiceMode="singleChoice"
        android:layout_gravity="start"></ListView>

</android.support.v4.widget.DrawerLayout>

我添加RelativeLayout和TextView，但模拟不起作用，我不知道为什么？我这样添加：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/wallpaper01"
    android:id="@+id/drawer_layout">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/main_content">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="luis"/>

    </RelativeLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start">
      <TextView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="hello"/>
      <ListView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/lv_sliding_menu"
        android:background="@drawable/wallpaper01"
        android:choiceMode="singleChoice"
        ></ListView>
    </RelativeLayout>
</android.support.v4.widget.DrawerLayout>

如何改变？

导航抽屉中的Listview xml设置为match_parent宽度和高度。这就是textview和imageview不可见的原因。
