Question

我使用本指南： https://developers.google.com/maps/documentation/android-api/

但它不起作用，我在谷歌控制台注册了API密钥，并在清单中添加，我添加了清单权限。

这是MapsActivity：

package aimprogman.mustwork;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}


/**
 * Manipulates the map once available.
 * This callback is triggered when the map is ready to be used.
 * This is where we can add markers or lines, add listeners or move the camera. In this case,
 * we just add a marker near Sydney, Australia.
 * If Google Play services is not installed on the device, the user will be prompted to install
 * it inside the SupportMapFragment. This method will only be triggered once the user has
 * installed Google Play services and returned to the app.
 */
@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
  }
}

这是activity_maps.xml

  <fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />

但它不起作用并显示错误：

Answer 1

对不起，我错过了添加

      <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

工作正常，谢谢

Answer 2

在你的xml中使用下面的代码

 <com.google.android.gms.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

在您的活动中，如下所示在OnCreate中启动 -

 mMapView = (MapView) rootView.findViewById(R.id.mapView);
    mMapView.onCreate(savedInstanceState);
  try {
        MapsInitializer.initialize(this);
    } catch (Exception e) {
        e.printStackTrace();
    }
 mMapView.getMapAsync(this);

这也是初始化地图的一种方式，它可以在所有设备上运行得更好。

如果你仍然想为你的地图使用地图片段，请告诉我你的清单，这样我就可以看到你错过了那里的东西。
