【问题描述】：

我想每 10 毫秒获取一次位置，但我的位置会在大约 30 秒或 40 秒内发生变化。我的错在哪里？有人帮助我吗？我正在使用这个代码块。我也用过，但我遇到了一些问题http://www.androidhive.info/2012/07/android-gps-location-manager-tutorial/

@Override
protected void onStart() 
    super.onStart();
    mGoogleApiClient.connect();


@Override
protected void onDestroy() 
    super.onDestroy();
    mGoogleApiClient.disconnect();


synchronized void buildGoogleApiClient() 
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();




@Override
public void onConnected(Bundle bundle) 
    mLocationRequest = LocationRequest.create();
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    mLocationRequest.setInterval(1); // Update location every second

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) 

        return;
    
    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);


    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
            mGoogleApiClient);
    if (mLastLocation != null) 
        lat = String.valueOf(mLastLocation.getLatitude());
        lon = String.valueOf(mLastLocation.getLongitude());

    


@Override
public void onConnectionSuspended(int i) 



@Override
public void onLocationChanged(Location location) 
    mLastLocation = location;
    Toast.makeText(MainActivity.this, location.getLatitude()+"+-+"+location.getLongitude(), Toast.LENGTH_SHORT).show();
    updateUI();


@Override
public void onConnectionFailed(ConnectionResult connectionResult) 
    buildGoogleApiClient();

void updateUI() 
    Log.e("Updated",lat+"---"+lon);

Android 版本 6.0.1

【参考方案1】：

你可以这样做：

mLocationRequest.setInterval(3000);
mLocationRequest.setFastestInterval(1000); // For 1 Second = 1000 millis

【讨论】：

它不起作用：/我再次每 40-50 秒获取一次位置。
