Description

Indicates how much of the extra space in the LinearLayout will be allocated to the view associated with these LayoutParams.

By setting a layout_weight for the Views inside the LinearLayout, the parent layout divides the available space between its children according to their weights.

Implementation

A Vertical LinearLayout with 2 Views. Top View has layout_weight of 3 and bottom one has 1, which means total of 4. Top View will fill 3/4 of the Layout and bottom one will fill 1/4 of the Layout.

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

    <View
        android:id="@+id/view1"
        android:layout_width="match_parent"
        android:layout_height="0px"
        android:layout_weight="3"/>

    <View
        android:id="@+id/view2"
        android:layout_width="match_parent"
        android:layout_height="0px"
        android:layout_weight="1"/>    

</LinearLayout>
