ListView drops to the bottom

问题

I am using the following layout. Basically, it has a custom toolbar, a Navigation Drawer, a menu, a ListView (listView1), and adlay.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/background">

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="@color/header_bg"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/toolbar">

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:ads="http://schemas.android.com/apk/res-auto"
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <ListView
            android:id="@+id/listView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="start"
            android:layout_above="@+id/adlay"
            android:layout_margin="7dp"
            android:cacheColorHint="#00000000"
            android:divider="@android:color/transparent"
            android:dividerHeight="3dp">
        </ListView>
        <LinearLayout
            android:id="@+id/adlay"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:orientation="vertical" >
        </LinearLayout>
    </RelativeLayout>

    <ListView
        android:id="@+id/drawer_list"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="#eee"
        android:dividerHeight="1dp"
        android:background="#fff"
        android:layout_below="@+id/toolbar"
        >
    </ListView>
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>

The layout is kind of like the following order:

1. Toolbar (with Navigation drawer and menu)
2. listView1
3. adlay

listView1 consists of a list of items loaded from external XML files.

Problem is this. If listView1's items is not much, then it drops to the bottom, sitting above adlay, and there is a gap above listView1, between the toolbar and listView1. The display is like the following:

1. Toolbar (with Navigation drawer and menu)
2. GAP! <--- I don't want the gap to be here!
3. listView1
4. adlay

This is not desired display.

Ideally, I want the following:

1. Toolbar (with Navigation drawer and menu)
2. listView1
3. GAP should be here
4. adlay

Any help is much appreciated. Thanks.
