    The layout includes a Button to trigger the Bitmap creation and an ImageView to display the resulting Bitmap.

    <LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Create Bitmap from View" />

    <ImageView
    android:id="@+id/imageView"
    android:layout_width="match_parent"
    android:layout_height="0dp"
