Question

I have ads layout under the ScrollView. In order to prevent the ScrollView overlapping ads layout, I have to use

<ScrollView 
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_weight="1" //          <--- THIS!
            >
                //...scrollview content
</ScrollView>

<include layout="@layout/ads_468x60"/>

What is the meaning of layout_weight if both width and height have been set to fill_parent?

According to documentation, this should not work, or to be precise, if both layout_height and layout_width have been set other than 0dp, then layout_weight is disregarded. But, in this example it works and bottom ads layout will not be shown without the attribute android:layout_weight="1" inside of the ScrollView.

Answer 1

use android:layout_height=”0dp”

android:layout_weight=”1″ tells layout manager to fill all the free space.
