android - 如何在5分钟的android系统中一次获取gps位置？

嗨，有人可以给我一个示例代码，每隔五分钟获取一次位置，请尝试一下，我只要按一下按钮就可以获取一次位置，
但我需要它显示一次五分钟。

谢谢你

这是我的代码:

public void checkLocation(View v) {

        //initialize location manager
        manager =  (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        //check if GPS is enabled
        //if not, notify user with a toast
        if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
            Toast.makeText(this, "GPS is disabled.", Toast.LENGTH_SHORT).show();
        } else {

            //get a location provider from location manager
            //empty criteria searches through all providers and returns the best one
            String providerName = manager.getBestProvider(new Criteria(), true);
            Location location = manager.getLastKnownLocation(providerName);

            TextView tv = (TextView)findViewById(R.id.locationResults);
            if (location != null) {
                tv.setText(location.getLatitude() + " latitude, " + location.getLongitude() + " longitude");
            } else {
                tv.setText("Last known location not found. Waiting for updated location...");
            }
            //sign up to be notified of location updates every 15 seconds - for production code this should be at least a minute
            manager.requestLocationUpdates(providerName, 15000, 1, this);
        }
    }

    @Override
    public void onLocationChanged(Location location) {
        TextView tv = (TextView)findViewById(R.id.locationResults);
        if (location != null) {
            tv.setText(location.getLatitude() + " latitude, " + location.getLongitude() + " longitude");
        } else {
            tv.setText("Problem getting location");
        }
    }

    @Override
    public void onProviderDisabled(String arg0) {}

    @Override
    public void onProviderEnabled(String arg0) {}

    @Override
    public void onStatusChanged(String arg0, int arg1, Bundle arg2) {}

    // Find the closest Bart Station
    public String findClosestBart(Location loc) {
        double lat = loc.getLatitude();
        double lon = loc.getLongitude();

        double curStatLat = 0;
        double curStatLon = 0;
        double shortestDistSoFar = Double.POSITIVE_INFINITY;
        double curDist;
        String curStat = null;
        String closestStat = null;

        //sort through all the stations
        // write some sort of for loop using the API.

        curDist = Math.sqrt( ((lat - curStatLat) * (lat - curStatLat)) +
                        ((lon - curStatLon) * (lon - curStatLon)) );
        if (curDist < shortestDistSoFar) {
            closestStat = curStat;
        }

        return closestStat;

        }

最佳答案

这是获取位置的代码，并将gps的监听器设置为在几分钟和距离上获取当前位置，我也使用了runnable对象在每几分钟上获取位置。

Location gpslocation = null;

private static final int GPS_TIME_INTERVAL = 60000; // get gps location every 1 min
private static final int GPS_DISTANCE= 1000; // set the distance value in meter

/*
   for frequently getting current position then above object value set to 0 for both you will get continues location but it drown the battery
*/

private void obtainLocation(){
if(locMan==null)
    locMan = (LocationManager) getSystemService(LOCATION_SERVICE);

    if(locMan.isProviderEnabled(LocationManager.GPS_PROVIDER)){
        gpslocation = locMan.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        if(isLocationListener){
             locMan.requestLocationUpdates(LocationManager.GPS_PROVIDER,
                        GPS_TIME_INTERVAL, GPS_DISTANCE, GPSListener);
                }
            }
        }
}

现在，使用此方法获取当前位置，并且每隔1分钟和1000米的距离，将在位置更改时调用监听器。

对于每5分钟一次的获取，您可以使用此处理程序并运行它以在设定好的时间段内获取此位置:

private static final int HANDLER_DELAY = 1000*60*5;

Handler handler = new Handler();
handler.postDelayed(new Runnable() {
        public void run() {
            myLocation = obtainLocation();
            handler.postDelayed(this, HANDLER_DELAY);
        }
    }, START_HANDLER_DELAY);

这是位置更改事件的GPS监听器:

private LocationListener GPSListener = new LocationListener(){
    public void onLocationChanged(Location location) {
        // update location
        locMan.removeUpdates(GPSListener); // remove this listener
    }

    public void onProviderDisabled(String provider) {
    }

    public void onProviderEnabled(String provider) {
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {
    }
};

您可以将监听器和处理程序的间隔时间设置为相同，以获取GPS位置。
