I advise you to use the weight to keep interoperability with other formats tablet.
My solution :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#AAAAAA"
android:orientation="vertical" >
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1"
    android:orientation="horizontal"
    tools:ignore="DisableBaselineAlignment" >
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="horizontal"
        tools:ignore="NestedWeights" >
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:orientation="vertical" >

                android:layout_margin="10dp"
                android:layout_weight="1"
