クラス直下で宣言
private PendingIntent pi; LocationManager mLocationManager; ReceiveLocation receiver;
onCreate内に以下を記述
mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE); receiver = new ReceiveLocation(); //指定したIntentに反応するようにReceiverにIntentFilterを登録 final IntentFilter filter = new IntentFilter(); filter.addAction("com.android.practice.ACTION_LOCATION_UPDATE"); registerReceiver(receiver, filter);
onResume内に以下を記述
//Intentを作成 final Intent nextIntent = new Intent(); nextIntent.setAction("com.android.practice.ACTION_LOCATION_UPDATE"); pi = PendingIntent.getBroadcast(this, 0, nextIntent, PendingIntent.FLAG_UPDATE_CURRENT); mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, pi);
onPause、もしくはonDestroyに以下が必要
mLocationManager.removeUpdates(pi);
onDestroyに以下が必要
unregisterReceiver(receiver);
通知を受け取るブロードキャストを作成
class ReceiveLocation extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { if(intent.hasExtra(LocationManager.KEY_LOCATION_CHANGED)){ LocationManager lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER); String message = "Location\n" + "Longitude:" + location.getLongitude() + "\n" + "Latitude:" + location.getLatitude(); Toast.makeText(context, message, Toast.LENGTH_LONG).show(); } } }
これは必要なのかわかりませんが、念のため
AndroidManifest.xmlのapplicationタグ内に記述します。
<receiver android:name="com.android.practice.LocationUpdateReceiver"/>
