I selected a Google Maps activity at the time the project was created, how do I add this button to the layout?
<Button
android:id="@+id/btn_draw_State"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_gravity="right|top"
android:layout_marginTop="55dp"
android:layout_marginRight="11dp" />
Layout:
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:id="@+id/map" tools:context=".MapsActivityWifi"
android:name="com.google.android.gms.maps.SupportMapFragment">
