How to divide layout to 3 parts?

Question

I\'m trying to divide my layout to 3 equal rows, trying to use LinearLayout and weights, but it doesn\'t work, it doesn\'t make any change:

Answer 1

At first, I didn't realise, that problem was not there. I had ScrollView and it made these layouts not work with weights. I added android:fillViewport="true" to ScrollView and it got fixed.

Answer 2

This will work

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

<LinearLayout
    android:id="@+id/lay1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:background="#ff0000" >

    <TextView
        android:id="@+id/textView01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />
</LinearLayout>

<LinearLayout
    android:id="@+id/lay2"
    android:layout_width="fill_parent"
    android:layout_height="0dip"
    android:layout_weight="1"
    android:background="#00ff00" >

    <TextView
        android:id="@+id/TextView02"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />
</LinearLayout>

<LinearLayout
    android:id="@+id/lay3"
    android:layout_width="fill_parent"
    android:layout_height="0dip"
    android:layout_weight="1" 
    android:background="#0000ff">

    <TextView
        android:id="@+id/TextView03"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />
</LinearLayout>
