我使用 Fused Location API 来获取位置更新。我在根据 setTimeInterval设置LocationRequest时收到更新。但我只需要更新 10m 运动。所以我放了 setSmallestDisplacement(10)。但是当我放setSmallestDisplacement(10)时，我没有得到更新。以下是我的 LocationUpdate 课程
public class LocationManger implements
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener, com.google.android.gms.location.LocationListener {
GoogleApiClient mLocationClient;
Location mCurrentLocation;
LocationRequest mLocationRequest;
Context mContext;
public LocationManger(Context context) {
super();
mLocationClient = new GoogleApiClient.Builder(context)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
mContext = context;
}
@Override
public void onLocationChanged(Location location) {
mCurrentLocation = location;
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Helper.showToast("failed", mContext);
}
@Override
public void onConnected(Bundle arg0) {
if (mLocationRequest == null) {
mLocationRequest = LocationRequest.create();
mLocationRequest.setSmallestDisplacement(10);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
LocationServices.FusedLocationApi.requestLocationUpdates(mLocationClient, mLocationRequest, this);
}
@Override
public void onConnectionSuspended(int i) {
mLocationClient.connect();
}
/**
* Function to start the location updates
*/
public void startLocationUpdates() {
if (!mLocationClient.isConnected())
mLocationClient.connect();
}
/**
* function to stop the location updates
*/
public void stopUpdatingLocation() {
if (mLocationClient.isConnected()) {
LocationServices.FusedLocationApi.removeLocationUpdates(mLocationClient, this);
}
mLocationClient.disconnect();
}
/**
* function to get the current latitude
*/
public double getCurrentLatitude() {
if (mCurrentLocation != null) {
return mCurrentLocation.getLatitude();
}
return 0;
}
/**
* function to get the current longitude
*/
public double getCurrentLongitude() {
if (mCurrentLocation != null) {
return mCurrentLocation.getLongitude();
}
return 0;
}
/**
* function to get the current location
*/
public Location getCurrentLocation() {
return LocationServices.FusedLocationApi.getLastLocation(mLocationClient);
}
}
如果有人知道这个问题，请给我一个解决方案。提前致谢
