Android 谷歌地图没有出现任何错误

我试图在模拟器中加载给定纬度和经度的谷歌地图

地图正在模拟器中加载，但没有标记，并且始终显示相同的视图

我一直在关注这个问题。下面是我的代码

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
double latitude = getIntent().getDoubleExtra("lat", 0);
    double longitude = getIntent().getDoubleExtra("lng", 0);

    Log.d("Zumbare","lat value : "+latitude);
    Log.d("Zumbare","lng value : "+longitude);

    LatLng position = new LatLng(latitude, longitude);

    MarkerOptions options = new MarkerOptions();
    options.position(position);
    options.title("Position");
    options.snippet("Latitude:"+latitude+",Longitude:"+longitude);
    options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN));


    SupportMapFragment fm = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
    GoogleMap googleMap = fm.getMap();
    googleMap.setMyLocationEnabled(true);
    googleMap.getUiSettings().setMyLocationButtonEnabled(true);
    googleMap.getUiSettings().setZoomControlsEnabled(true);
    googleMap.getUiSettings().setCompassEnabled(true);

    googleMap.addMarker(options);
    CameraUpdate updatePosition = CameraUpdateFactory.newLatLng(position);
    CameraUpdate updateZoom = CameraUpdateFactory.zoomBy(4);
    googleMap.moveCamera(updatePosition);
    googleMap.animateCamera(updateZoom);

}

编辑2：

我正在使用android studio，并在gradle文件中添加了google play服务，如下所示

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.google.android.gms:play-services:3.1.36'
}

我认为你遵循的教程已经过时了<代码>播放服务现在是

6.5.87

请尝试一步一步地跟随，你最终会在你的手机上得到一张地图

维护活动

，示例代码：

public class MainActivity extends Activity {

    private static LatLng goodLatLng = new LatLng(37, -120);
    private GoogleMap googleMap;
    private EditText et_address, et_finalAddress;
    LatLng addressPos, finalAddressPos;
    Marker addressMarker;

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

        et_address = (EditText) findViewById(R.id.addressEditText);
        et_finalAddress = (EditText) findViewById(R.id.finalAddressEditText);


        // Initial Map
        try {

            if (googleMap == null) {
                googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        // Put a dot on my current location
        googleMap.setMyLocationEnabled(true);
        googleMap.setIndoorEnabled(true);
        googleMap.setTrafficEnabled(true);
        // 3D building
        googleMap.setBuildingsEnabled(true);
        // Get zoom button
        googleMap.getUiSettings().setZoomControlsEnabled(true);

        Marker marker = googleMap.addMarker(new MarkerOptions()
                .position(goodLatLng)
                .title("Hello"));
    }

您确定获取正确的lat和LAG吗？是的，我获取正确的lat long。我希望在Emulator中获得相同的lat和LAG，而不是在设备中。作为

Emulator

您需要设置

播放服务

，您可以参考

public class MainActivity extends Activity {

    private static LatLng goodLatLng = new LatLng(37, -120);
    private GoogleMap googleMap;
    private EditText et_address, et_finalAddress;
    LatLng addressPos, finalAddressPos;
    Marker addressMarker;

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

        et_address = (EditText) findViewById(R.id.addressEditText);
        et_finalAddress = (EditText) findViewById(R.id.finalAddressEditText);


        // Initial Map
        try {

            if (googleMap == null) {
                googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        // Put a dot on my current location
        googleMap.setMyLocationEnabled(true);
        googleMap.setIndoorEnabled(true);
        googleMap.setTrafficEnabled(true);
        // 3D building
        googleMap.setBuildingsEnabled(true);
        // Get zoom button
        googleMap.getUiSettings().setZoomControlsEnabled(true);

        Marker marker = googleMap.addMarker(new MarkerOptions()
                .position(goodLatLng)
                .title("Hello"));
    }
