java - Android 获取当前位置失败

Question

通过这个函数我得到经度 = 0 和纬度 = 0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 Google API 客户端提供的 onConnected() 回调中执行此操作，该回调在客户端准备就绪时调用。以下代码 fragment 说明了请求和响应的简单处理:

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()));
    }
}
}
