To provide size distribution without hard coding it, in xml ,you need to do following steps

1. Use "android:weightSum" attribute in parent container and "android:layout_weight" in inner view.
2. In inner view when you are using android:layout_weight, you need to provide "android:layout_height='0'" (if you are dividing it vertically) or "android:layout_width='0dp'" (if you are diving it horizontally).
3. android:weightSum in parent should be summation if all layout_weight in inner view.

Example: Below code shows vertically two 50% linear layout design.

HTML

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:weightSum="2">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">50%</LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:removed="@color/colorAccent">50%
    </LinearLayout>
</LinearLayout>

Let me know if that helps.
