android weightSum not working properly

Question

I have a layout with three elements and its orientation is 'horizontal'

I want to fix the size that each element occupy in my layout.

first element should take 40% of the total space then second element should occupy 5% and third one should occupy remaining 55% space.

My layout look like this:

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


<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="100" >

    <TextView
        android:id="@+id/outletname"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="40"
        android:text="@string/outlet_name2" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="5"
        android:text=": " />

    <TextView
        android:id="@+id/outletnamevalue"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="55"
        android:text="abcdefttt" />
</LinearLayout>
</LinearLayout>

text in 'TextView' will change dynamically , So I want to keep the constant space for elements irrespective of the content in views...

In order to make weight effective, you must also need to set the widths of your TextViews to 0dp.

android:layout_width="0dp"
