Question

我开始执行Activity时只看到白屏：

public class MapActivity extends AppCompatActivity implements OnMapReadyCallback {

    SupportMapFragment mapFragment;
    public static final String DISPLAY_MARKERS_LIMIT = "map_activity_display_markers_limit";

    public static final int MARKERS_LIMIT = 1000;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);


    }


    @Override
    public void onMapReady(GoogleMap googleMap) {

        googleMap.addMarker(new MarkerOptions()
                .position(new LatLng(37.4233438, -122.0728817))
                .title("LinkedIn")
                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));

        googleMap.addMarker(new MarkerOptions()
                .position(new LatLng(37.4629101,-122.2449094))
                .title("Facebook")
                .snippet("Facebook HQ: Menlo Park"));

        googleMap.addMarker(new MarkerOptions()
                .position(new LatLng(37.3092293, -122.1136845))
                .title("Apple"));

        googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(37.4233438, -122.0728817), 10));

    }
}

我看到的是logis

这是我的布局

<include layout="@layout/content_main" />

这是content_main

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context=".activities.MapActivity"
    tools:showIn="@layout/activity_main">

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_gravity="center"
        android:layout_height="match_parent"
        />

</RelativeLayout>

activity_main ::

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".activities.MapActivity">

    <include layout="@layout/content_main" />


</RelativeLayout>

我认为这导致海湾地区没有Google地图的api键。（如果尚未将SHA-1添加到密钥，则将新的SHA-1证书指纹添加到地图）。您可能会在下面的链接中找到帮助 https://developers.google.com/maps/documentation/android-sdk/signup
