Текущее местоположение работает в отдельном приложении,Но это не работает, если интегрировать его с блоком навигации.

Я добавил нижний лист в contentmain.xml , который показывает некоторые данные и карту Google.Но это не показывало текущее местоположение.без ошибок

Похоже, проблема в вашем макете.Вы можете использовать LinearLayout, чтобы справиться с этой проблемой.

Важная часть: свойство 

<RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_weight="1"
