Creating a chat layout?

Question

I attempted to create a android chat layout in xml, but I could not get things how I wanted. This is the closest I could get:

Answer 1

Try not giving the bottom section a weight, but just wrap content, then have the top scroll fill remaining space by giving it a weight of 1. Like this

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <ScrollView 
        android:layout_width="fill_parent"
        android:layout_height="0dip" 
        android:layout_weight="1"  >
        <TextView 
            android:text="@string/text" 
            android:id="@+id/textOutput"
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content"
            android:paddingLeft="5dp" 
            android:paddingRight="5dp" 
            android:paddingTop="5dp" />
    </ScrollView>

    <LinearLayout 
        android:id="@+id/linearLayout1"
        android:orientation="horizontal" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        android:paddingLeft="5dp" 
        android:paddingRight="5dp"
        android:paddingBottom="5dp"
        android:baselineAligned="true">
        <EditText android:layout_weight="1" android:id="@+id/textInput"
            android:layout_height="45dp" android:layout_width="0dip">
            <requestFocus></requestFocus>
        </EditText>
        <Button android:text="Send"
            android:layout_height="45dp" android:layout_width="125dp"
            android:id="@+id/btnSend"></Button>
    </LinearLayout>
</LinearLayout>
