Answer 1

Try this xml. It contain 2 containers one for camera preview and other for hints whose background needs to be invisible to show the underlying camera preview inside FrameLayout which enables one container to be above the other.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
    android:id="@+id/camera_preview_linear_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <SurfaceView
        android:id="@+id/camera_preview_surface_view"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="match_parent">
    </SurfaceView>    
    <Button
        android:id="@+id/camera_takepicture_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Take picture">
</LinearLayout>
<LinearLayout
    android:id="@+id/camera_preview_hints"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#00000000"
    android:orientation="vertical"> 
    <!-- Your hint goes here-->
</LinearLayout>
</FrameLayout>
