i have 2 linearlayouts of weight1,with 1st layout,if add occupies full width instead of half of screen,how avoid 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"      android:paddingbottom="@dimen/activity_vertical_margin"      android:paddingleft="@dimen/activity_horizontal_margin"      android:paddingright="@dimen/activity_horizontal_margin"      android:paddingtop="@dimen/activity_vertical_margin"      android:weightsum="2"      tools:context="com.example.testapp1.mainactivity" >        <linearlayout          android:layout_width="match_parent"          android:layout_height="wrap_content"          android:layout_weight="1"          android:background="@color/aqua"          android:orientation="vertical"          android:weightsum="2" >            <linearlayout              android:id="@+id/subview_1"              android:layout_width="match_parent"              android:layout_height="wrap_content"              android:background="@color/green"              android:orientation="vertical" >                <relativelayout                  android:id="@+id/insidelayout"                  android:layout_width="match_parent"                  android:layout_height="wrap_content"                  android:background="@color/yellow" >                    <linearlayout                      android:layout_width="wrap_content"                      android:layout_height="wrap_content"                      android:background="@color/aqua"                      android:orientation="vertical" >                        <view                          android:layout_width="wrap_content"                          android:layout_height="wrap_content"                          android:background="@color/darkgray" />                  </linearlayout>              </relativelayout>          </linearlayout>      </linearlayout>        <linearlayout          android:layout_width="match_parent"          android:layout_height="wrap_content"          android:layout_weight="1"          android:background="@color/blueviolet"          android:orientation="vertical" >      </linearlayout>    </linearlayout>

on adding view tag,it occupies full width instead of half specified in weight1,what problem making

let's simplify problem. below should work. recommend imagine weight percentage of 100 , if want half , half 50,50 (if wanted third each 33,33,33). no need weightsum have been removed. missing layout_height of 0dip allows weight define space taken.

<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:paddingleft="@dimen/activity_horizontal_margin"     android:paddingright="@dimen/activity_horizontal_margin"     android:paddingtop="@dimen/activity_vertical_margin"     tools:context="com.example.testapp1.mainactivity" >      <linearlayout         android:layout_width="match_parent"         android:layout_height="0dip"         android:layout_weight="50"         android:orientation="vertical">     </linearlayout>      <linearlayout         android:layout_width="match_parent"         android:layout_height="0dip"         android:layout_weight="50"         android:orientation="vertical" >      </linearlayout>  </linearlayout>
