Frame Layout

Frame Layout is designed to block out an area on the screen to display a single item. Generally this layout should be used to hold a single child view, because it can be difficult to position different child views in same layout. You can add multilple chlidren to Frame Layout and control their positions within the Frame Layout by assigning gravity to each field, using the android:layout_gravity attribute.

 Important attributes of Frame Layout:

Attribute
Description
android:id
This is the ID which uniquely identifies the layout.
android:foreground
This specifies the the drawable to draw over the content and possible values may  be a color value, in the form of #rgb, #argb, #rrggbb or #aarrggbb.
android:foregroundGravity
Defines the gravity to apply the foreground drawable. The gravity defaults to fill. Possible values are top, bottom, left, center, right, center_vertical, center_horizontal etc.
Android:measureAllChildren
Determines whether to measure all children or just those in the VISIBLE or INVISIBLE state when measuring. Defaults to false.
  
Example:
<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/frame1"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:contentDescription="@string/img"
        android:src="@drawable/ic_launcher" />
    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="@string/hint" />
    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        android:text="@string/text1"
        android:textSize="16sp"
        android:textStyle="bold" />
    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="200dp"
        android:layout_marginTop="20dp"
        android:text="@string/btn" />
    <TextView
        android:id="@+id/textView2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:padding="20dp"
