Question

I'm making an app for Android device and I'm trying to have a ScrollView inside a LinearLayout but when I try to do this the ScrollView take all the space and elements who are after the ScrollView in the LinearLayout disapear.

For example:
If the ScrollView is not "full":

If the ScrollView is "full":

As you can see the button disapear...
Here is the code of this Activity:

<LinearLayout
    android:id="@+id/linearLayout1"
    android:layout_width="fill_parent"
    android:layout_marginLeft="50dp"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:orientation="vertical"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:background="@drawable/linearlayoutbackground" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/nom_des_joueurs"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:layout_marginBottom="30dp" />

    <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

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

        </LinearLayout>

    </ScrollView>

    <Button
        android:id="@+id/okPlayersName"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@string/ok"
        android:background="@drawable/backgroundbutton"
        android:layout_marginTop="30dp" />
</LinearLayout>

After I add elements in the LinearLayout who are in the ScrollView.
Any solution?
Thanks.

Try the following:

android:layout_height="0dp"
android:layout_weight="1"

This tells your ScrollView to take all the remaining space not occupied by the other elements.
