How to implement this layout?

I would like to 开发者_运维百科divide my current view into 4 areas (not divide the screen into 4, but divide the view) like following:

I would like to have the following sized layout for the view:

That's horizontally divided into half of the view for each. vertically, the upper area has 1/3 view height and lower two areas holds 2/3 view height.

I do successfully divided my view into 4 equal sized areas by:

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
    <LinearLayout
        android:id="@+id/top_area"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"

            android:background="@drawable/content_blue_bg"
            >
            <TextView

                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:text="TOP LEFT"/>
        </LinearLayout>

        <LinearLayout

            android:background="@drawable/content_blue_bg"
            >
            <TextView

                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:text="TOP RIGHT"/>
        </LinearLayout>

    </LinearLayout>

    <LinearLayout
        android:id="@+id/bottom_area"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"    
        android:orientation="horizontal"
        >

        <LinearLayout
            android:id="@+id/bottom_left_area"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"

            >

                <TextView 
               android:layout_width="fill_parent"
               android:layout_height="fill_parent"
               android:text="BOTTOM LEFT"/>
        </LinearLayout>

        <LinearLayout
            android:id="@+id/bottom_right_area"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_weight="1"
            android:background="@drawable/content_blue_bg"
            >
            <TextView

                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:text="BOTTOM RIGHT"/>
        </LinearLayout>
    </LinearLayout>

</LinearLayout>

But how can I have the 1/3 view height for the uper areas and 2/3 view height for the lower areas?

All you were missing is setting the bottom layout to 70% and the top layout to 30%

This had just been posted on my Twitter http://blog.stylingandroid.com/archives/297 :-)

just change the android:layout_weight for the bottom_area LinearLayout to 2 instead of 1
