Question

I got such problem: i have a MapView and a ListView below it. Map size is fixed. But I need to scroll my views together. I, somehow, handled problems with non-scrolling map and one-itemed-list, but another one showed up – in a ScrollView there are lots of free space below ListView and I can’t get rid of it. I thought that setting for the list to “wrap_content” would help, but it did not.
What to do?
Here is my layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/scrollView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fillViewport="true">

        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <com.package.MyMapView
                     android:layout_width="match_parent"
                     android:layout_height="100dp"
                     android:clickable="true"
                     android:apiKey="key"
                     android:id="@+id/map"
                     android:layout_gravity="top"/>
        <ListView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/channelsList" >

        </ListView>

    </LinearLayout>

    </ScrollView>
</LinearLayout>

Its always not a good idea to wrap ListView inside ScrollView, because both are scrollable views.
