Answer 1

Use Relativelayout as parent layout and it will work file

 <Relativelayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical">
<View
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_marginStart="40dp"
android:layout_marginEnd="40dp"
android:background="@color/dark_green">
</View>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="-100dp"
android:background="@color/green">
 </View>
 </Relativelayout >
