Question

I have screen with ScrollView and three different LinearLayouts.

One LinearLayout contains a Spinner and second contains ListView and third contains two Buttons ( horizontal ).

I want to display a screen that contains 3 LinearLayouts always displayed at bottom of screen and 1 LinearLayout always displayed on top. In middle part , i want to display ListView content. So that on whole screen there is no blank space present.

I want to create screen for multiple devices which has different sizes.

Screen Layout with what I want:

Answer 1

This is a very simple solution. You should be able to use this in your current layout.

Just populate the LinearLayouts with your desired contents.

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

    <LinearLayout
        android:id="@+id/ll1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1" >
    </LinearLayout>

    <LinearLayout
        android:id="@+id/ll2"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1" >
    </LinearLayout>

    <LinearLayout
        android:id="@+id/ll3"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1" >
    </LinearLayout>

</LinearLayout>
