近接アラートで配列を受信しようとしています。私が送ることができたのは、1つのロングだけです。これは私が近接アラートを設定する方法です：
private void setProximityAlert(double lat, double lon, final long eventID, int requestCode)
{
float radius = 30f;
LocationManager locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Intent intent = new Intent(PROXIMITY_INTENT_ACTION);
intent.putExtra(ProximityAlert.EVENT_ID_INTENT_EXTRA, eventID);
intent.putExtra("pole", mPositions);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), requestCode, intent, PendingIntent.FLAG_CANCEL_CURRENT);
locManager.addProximityAlert(lat, lon, radius, -1, pendingIntent);
}
「intent.putExtra("pole", mPositions);」とコメントしてもクラッシュしません。
これは配列です：
private ArrayList<LatLonPair> mPositions;
そして、これはレシーバーです：
public class ProximityAlert extends BroadcastReceiver {
public static final String EVENT_ID_INTENT_EXTRA = "EventIDIntentExtraKey";
@Override
public void onReceive(Context context, Intent intent) {
long eventID = intent.getLongExtra(EVENT_ID_INTENT_EXTRA, -1);
ArrayList<LatLonPair> list = (ArrayList<LatLonPair>) intent.getSerializableExtra("list");
Toast.makeText(context, "Event: " + eventID, Toast.LENGTH_SHORT).show();
}
}
1つの putExtra がなくても機能しますが、その配列が必要です。したがって、これは私にとってはうまくいきません: インテントによるオブジェクトの配列リスト
