FrameLayout is not the better way to do this:
Use RelativeLayout instead.
You can position the elements anywhere you like.
The element that comes after, has the higher z-index than the previous one (i.e. it comes over the previous one).
Example:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent" android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorPrimary"
app:srcCompat="@drawable/ic_information"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is a text."
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:layout_margin="8dp"
android:padding="5dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:background="#A000"
android:textColor="@android:color/white"/>
</RelativeLayout>
