Android : dividing screen into 6 areas with detecting multi touches

I'm an absolute beginner with android, I found a code that detects multitouches and another code that splits the screen into 6 areas here is the layout for each code :

<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="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:orientation="horizontal" >

    <LinearLayout     
        android:background="@android:color/black"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="horizontal" >
    </LinearLayout>

    <LinearLayout
        android:background="@android:color/white"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="horizontal" >
    </LinearLayout>
</LinearLayout>


<LinearLayout   
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:orientation="horizontal" >

    <LinearLayout
        android:background="@android:color/black"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="horizontal" >
    </LinearLayout>

    <LinearLayout
        android:background="@android:color/darker_gray"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="horizontal" >
    </LinearLayout>


</LinearLayout>

<LinearLayout

    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:orientation="horizontal" >

    <LinearLayout
        android:background="@android:color/white"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="horizontal" >
    </LinearLayout>

    <LinearLayout
        android:background="@android:color/black"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="horizontal" >
    </LinearLayout>


</LinearLayout>

layout for detecting multitouches :

    <com.example.multitouch.MultitouchView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

my question is how to combine these two layouts? and how to know each touch in which area lies ? Thanks in advance
