How to wrap background color for some widgets?

Question

I want add background for a group of widgets

First I tried to use View, the app will crash

<View
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#FFC3D7">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="&lt;"
        android:textSize="20sp"
        android:textColor="@android:color/white"/>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="title"
        android:textSize="20sp"
        android:gravity="center_horizontal"
        android:textColor="@android:color/white"/>
</View>

Then I tried RelativeLayout, it is work, but it cannot wrap the content

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#FFC3D7">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="&lt;"
        android:textSize="20sp"
        android:textColor="@android:color/white"/>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="title"
        android:textSize="20sp"
        android:gravity="center_horizontal"
        android:textColor="@android:color/white"/>
</RelativeLayout>

What is correct way to add background color for widgets?
