Android RelativeLayout placing 2 views next to eachother one view is variable?

Tag: android,android-layout

I am looking at placing 2 views next to each other. 1 View has a fixed width while the other should take up the rest of the space (variable).

I have currently set the layout with the fixed width view with the alignParentRight="true" that is fine however it overlaps the variable width view.

I would like them to be side-by-side. Maybe a Horizontal LinearLayout is best for this task?

What I have currently is:

<ListView
    android:id="@+id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

<Selector
    android:id="@+id/side_selector"
    android:layout_width="30dp"
    android:layout_height="match_parent"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"
    />

Best How To :

You have to use LinearLayout with layou_weigth, just like this :

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <ListView
        android:id="@+id/list"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"/>

    <Selector
        android:id="@+id/side_selector"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"/>

</LinearLayout>
