因此，我尝试使用Google Maps Fragment进行简单的应用程序。我从Android-Studio的预设开始。从新开始，显示工具栏但不显示地图片段。接下来，您将看到我的代码和堆栈跟踪：

@Override

mMap = googleMap;
// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-34, 151);

这一遍又一遍地重复。我使用的是带有Android 6.0.1的OnePlus One并显示了API 23.应用程序运行，但它没有显示地图片段。
答案 0 :(得分：0)
布局：
如果您使用的是自定义工具栏，请更好地将 样式 更改为 的 NoActionBar
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
使用相对布局， 对于工具栏，请保持
android:layout_alignParentTop="true"
和该地图片段
android:layout_below="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
这只会将工具栏放在顶部和下部作为地图片段。
现在地图没有显示：
您是否已将 Google Play服务依赖项添加到您的应用中？
同时将此文件添加到您的权限之上的清单文件中。
<permission
android:name="your_package_name.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/>
抱歉，我无法发表评论，所以发布了一个答案。
希望它有所帮助!!
