Кнопки управления картой Google (такие как mylocation et c) исчезают при реализации в фрагменте

/ 22 марта 2020

Я использовал Google map API в приложении android, я использовал навигацию с вкладками, которая состоит из трех фрагментов, я внедрил карты Google в один из фрагментов, но теперь я не вижу кнопок управления. Я перепробовал все, включая перемещение кнопок управления, но ни одна из них не помогла.

Вот моя java активность MapActivity

Ваши кнопки не отображаются из-за того, что width_and_height фрагмента карты соответствует ширине родительского width_and_height. 

<RelativeLayout
    ...
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    ...
    tools:context=".MapsActivity">

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
    ...
        android:layout_width="match_parent"
        android:layout_height="match_parent"
    ...
        tools:context=".MapsActivity" />

Одно решение можно увидеть в примере ниже. Высота карты будет соответствующим образом скорректирована в зависимости от содержимого внутри LinearLayout.
