Linearlayout not displaying anything

I using android:layout_weight to limit the size of my view but now I'm not seeing anything on the screen. Here are the codes:

<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">

    <LinearLayout 
                android:layout_width="0dp" 
                android:layout_height="wrap_content" 
                android:layout_weight="2" 
                android:orientation="vertical"/>
   <ScrollView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content">



            <LinearLayout 
                android:layout_width="0dp" 
                             android:layout_height="wrap_content" 
                             android:layout_weight="3" 
                android:orientation="vertical"
               >

You should use weightSum property in your parent Linear layout, like android:weightSum="number of child"

Try this:

<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">

    <LinearLayout 
                android:layout_width="100dp" 
                android:layout_height="wrap_content" 
                android:layout_weight="2" 
                android:orientation="vertical"/>
                <ScrollView
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content">

                     <LinearLayout 
                         android:layout_width="50dp" 
                         android:layout_height="wrap_content" 
                         android:layout_weight="3" 
                         android:orientation="vertical"
                      >

This will help you to see something. Change the width according to your requirement.

Setting android:layout_width="0dp" will make this layout invisible. Change it to wrap_content or something else.
