Question

I have a simple question for you: is it possible to force no screen overflow in a layout that contains a ScrollView?

For instance, if i have the following layout:

<LinearLayout
    android:id="@+id/wrapper_table"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">     
    </LinearLayout>

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TableLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
        </TableLayout>
    </ScrollView>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">     
    </LinearLayout>

</LinearLayout>

If The TableLayout has many TableRow the Scrollview is being expanded up to the end of the screen and the lower LinearLayout is no more visible. Is it possible to force, without set height, ScrollView height in order to let enough space to display the lower LinearLayout?

Thank you!!

Apply an android:layout_weight to the ScrollView; this way it will take up whatever space is not taken by the other elements.

In the adjustments below, the two LinearLayouts will take up enough space to accomodate their content, and the ScrollView will take up whatever is left:

<LinearLayout
    android:id="@+id/wrapper_table"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">    
    </LinearLayout>

    <!-- This should be weighted height -->
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="0px"
        android:layout_weight="1">

        <TableLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
        </TableLayout>
    </ScrollView>

    <!-- This should be wrap_content height -->
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">    
    </LinearLayout>

</LinearLayout>
