Question

我正在测试使用内置Eclipse工具将坐标发送到Android模拟器的选项。但它似乎没有收到它们。我有这个简单的代码：

public class Main extends MapActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    MapView view = (MapView) findViewById(R.id.themap);
    view.setBuiltInZoomControls(true);

    final MapController mp = view.getController();

    LocationManager manager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

    LocationListener listener = new LocationListener() {

        public void onStatusChanged(String provider, int status, Bundle extras) {
            // TODO Auto-generated method stub

        }

        public void onProviderEnabled(String provider) {
            // TODO Auto-generated method stub

        }

        public void onProviderDisabled(String provider) {
            // TODO Auto-generated method stub

        }

        public void onLocationChanged(final Location location) {
            // TODO Auto-generated method stub
            mp.setCenter(new GeoPoint((int)location.getLatitude(), (int)location.getLongitude()));

        }
    };
    manager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, listener);

}



@Override
protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    return false;
}
}

我在Manifest中拥有ACCESS_FINE_LOCATION和INTERNET的权限。如果有人有任何解释，我将不胜感激。

Answer 1

你添加了

吗？

<uses-library android:name="com.google.android.maps" />

清单中的应用程序标签？您还需要来自Google的SDK调试证书的MD5指纹才能接收Google地图数据。你可以得到它here。

尝试在onLocationChanged方法中放置一个断点，并查看在将位置命令发送到模拟器时是否停止。当你还没有证书时，这也应该有用。

Answer 2

这对我有用。

监听器实现......

public class MyLocationListener implements LocationListener {
    public static final String TAG = "MyLocationListener";

    private Context context;

    public MyLocationListener(Context c) {
        this.context = c;
    }

public void onLocationChanged(android.location.Location location) {
        Log.d(TAG,"LocationChanged: Lat: "+location.getLatitude()+" Lng: "+location.getLongitude());
    }
}

...用法

MyLocationListener locationListener = new MyLocationListener(this);
// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,locationListener);

将位置发送到模拟器
