Make android layout child wider than parent?

Question

My code is:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="30dp"
    android:layout_marginRight="30dp">

    <View
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:layout_gravity="center"
        android:background="#00ff00"/>
</android.support.v7.widget.CardView>

My output is I want to green view to match the whole screen parent width. Is this possible? I want to use the card view as a parent, because it will have elevation.

Just remove this two line from your parent view.... `android:layout_marginLeft="30dp" android:layout_marginRight="30dp"` — Gowthaman M, Oct 15 '18 at 10:53
@GowthamanM the ideea is to have the margin on the parent, and not have on the child — Boldijar Paul, Oct 15 '18 at 13:45
well think logically how it will happen..child will perform based on parent attributes.. — Gowthaman M, Oct 15 '18 at 13:50

Here's your solution...

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <CardView
        android:id="@+id/cardView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginLeft="30dp"
        android:layout_marginRight="30dp"
        />
    <View
        android:id="@+id/fab"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:layout_centerVertical="true"
        android:background="#00ff00"
        />
</RelativeLayout>
