android locationManager requestLocationUpdates

Question

有没有办法在特定的intervan上从locationManager请求位置更新并忽略minDistance？我试过了

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3600 * 1000, 1, this)

但是在日志中有时会显示位置会在几分钟内更新，有时会在半小时内更新......是否可以按固定间隔更新位置并忽略距离？

您可以使用此架构。创建新的Runnable，每当你想要它时都会调用它

private final Handler _handler = new Handler();
private static int DATA_INTERVAL =  60 * 1000;

private final Runnable getData = new Runnable()
{
    @Override
    public void run()
    {
        getDataFrame();
    }
};
private void getDataFrame() 
{
    requestGPS();
    Timer time = new Timer();
    time.schedule(new TimerTask() {
            @Override
            public void run() {
                _locationManager.removeUpdates(_connector);
                this.cancel();
            }
        }, 5000, 5000);
    _handler.postDelayed(getData, DATA_INTERVAL);
}
private void requestGPS() 
{
    _locationManager.requestLocationUpdates(
    LocationManager.GPS_PROVIDER,
                0,
                0,
                _connector);
}
