<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <com.adamish.android.dmxapp.DmxView2d android:layout_width="match_parent" android:layout_height="fill_parent" android:id="@+id/laser_pos_panel" /> </LinearLayout>
