Answer 1

Use this line in your Frame layout:

android:layout_gravity="center_vertical|center_horizontal"
android:foregroundGravity="center"

<com.nexbits.digitechi.DrawCanvas
    android:id="@+id/SurfaceView"
    android:layout_gravity="center_vertical|center_horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Answer 2

I achieved it by adding to Child (something inside frame layout)

  android:layout_gravity="center"
