我想要計算您當前位置和三個標記之間的距離。 一切工作正常,但如果我改變我的位置的距離等於前的距離,我沒有得到新的座標。這裏是我的代碼:如何獲得總是最新的當前座標
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Location current = locationManager.getLastKnownLocation(locationManager.getBestProvider(criteria, true));
latng = String.valueOf(current.getLatitude());
lngon = String.valueOf(current.getLongitude());
Location club = new Location("clubloc");
club.setLatitude(Double.parseDouble(marker_data.get("lat")));
club.setLongitude(Double.parseDouble(marker_data.get("lng")));
double distance = current.distanceTo(club);
distance = distance/1000;
distance = Math.round(distance * 100);
distance = distance/100;
TextView dis = (TextView) findViewById(R.id.distance);
dis.setText(String.valueOf(distance) + "KM");
}
所以我的問題是我怎麼可以更新我的座標,所以我總是得到正確的距離是多少?
感謝兄弟我解決了它使用onLocationChanged方法 –
