的Android获取当前位置与此函数失败

Question

我得到经度= 0和纬度= 0 我不知道问题出在哪里

private void getCurrentLocation() { 

    Location location = LocationServices.FusedLocationApi.getLastLocation(googleApiClient); 
    if (location != null) { 
     //Getting longitude and latitude 
     longitude = location.getLongitude(); 
     latitude = location.getLatitude(); 

     //moving the map to location 
     moveMap(); 
    } 
} 

Answer 1

在由谷歌API客户端，提供的onConnected()回调做这里面在客户端准备就绪时调用。以下代码片段说明了请求并简单处理了响应：

public class MainActivity extends ActionBarActivity implements 
    ConnectionCallbacks, OnConnectionFailedListener { 
... 
@Override 
public void onConnected(Bundle connectionHint) { 
    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
      mGoogleApiClient); 
    if (mLastLocation != null) { 
     mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude())); 
     mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude())); 
    } 
} 
}
