Why layout_weight and weightSum aren't working for me?

Question

I have a small question about linearlayouts.

Let's say i have, 1 horizontal linearlayout that contains 6 vertical linearlayouts.

I can make all linearslayouts the same width size if i use weightsum=12(of horizontal ll) and layout_weight=2(for vertical ll)

Result :

Now i want the "test1" layout to be 2 or 3 times smaller than the others. I tried with weightsum=11, and layout_weigth=1(for the test1 layout) and layout_weight=2(for the others). I can't make it work, here is my code...

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:orientation="vertical">

 <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="11">

    <LinearLayout
        android:layout_width="match_parent"

        <TextView

How can i do it?

Thank you.

You need to use : android:layout_width="0dp" for the Linearlayout with the android:layout_weight="1" set as 1.

Now i want the "test1" layout to be 2 or 3 times smaller than the others

You can reduce the layout weight attribute of test1. to 0.5..

use this layout:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingTop="@dimen/activity_vertical_margin">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="6">

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight=".5"
            android:background="@drawable/border"
            android:orientation="vertical">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:text="test1" />


        </LinearLayout>

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1.5"
            android:background="@drawable/border"
            android:orientation="vertical">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:text="test" />

        </LinearLayout>

        <LinearLayout

            android:background="@drawable/border"
            android:orientation="vertical">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:text="test" />

        </LinearLayout>

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"

            android:background="@drawable/border"
