は私の定数クラスがされGeofenceTransitionsIntentServiceクラスここ
public class GTIS extends IntentService
{
protected static final String TAG = "GeofenceTransitionsIS";
public GTIS() {
super(TAG); // use TAG to name the IntentService worker thread
}
@Override
protected void onHandleIntent(Intent intent) {
GeofencingEvent event = GeofencingEvent.fromIntent(intent);
if (event.hasError()) {
Log.e(TAG, "GeofencingEvent Error: " + event.getErrorCode());
String description = getGeofenceTransitionDetails(event);
sendNotification(description);
return;
}
}
private static String getGeofenceTransitionDetails(GeofencingEvent event) {
String transitionString =
GeofenceStatusCodes.getStatusCodeString(event.getGeofenceTransition());
List triggeringIDs = new ArrayList();
for (Geofence geofence : event.getTriggeringGeofences()) {
triggeringIDs.add(geofence.getRequestId());
}
return String.format("%s: %s", transitionString, TextUtils.join(", ", triggeringIDs));
}
private void sendNotification(String notificationDetails) {
// Create an explicit content Intent that starts MainActivity.
Intent notificationIntent = new Intent(getApplicationContext(), Geofence.class);
// Get a PendingIntent containing the entire back stack.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(GeoFence.class).addNextIntent(notificationIntent);
PendingIntent notificationPendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
// Get a notification builder that's compatible with platform versions >= 4
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
// Define the notification settings.
builder.setColor(Color.RED)
.setContentTitle(notificationDetails)
.setContentText("Click notification to return to App")
.setContentIntent(notificationPendingIntent)
.setAutoCancel(true);
// Fire and notify the built Notification.
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());
}
}
ですNotificationは、Toastではありません。あなたは何のエラーはあなたがする必要がどのような
が起こらないので、あなたの場合にはトリガされませんif(event.hasError())文の中sendNotification()を呼び出しているので、それはあなたのために働いていないことである：
再び
@Override
protected void onHandleIntent(Intent intent) {
GeofencingEvent event = GeofencingEvent.fromIntent(intent);
if (event.hasError()) {
Log.e(TAG, "GeofencingEvent Error: " + event.getErrorCode());
}
String description = getGeofenceTransitionDetails(event);
sendNotification(description);
}
、このコードが表示されるでしょう
- アプリもちょうど示すジオフェンス遷移とトーストの時点でアクティブではないかもしれない○：これらの理由で実際の生活のアプリで
Toastより理にかなってNotificationあなたにとっては奇妙に見えることはありません。
- 通知は、あなたがより多くの情報（タイトル、テキスト）を表示し、多分あなたのアプリに戻って送ることができます
それは、ユーザを読み取り、あなたはまだしたい場合は、その利便性
でそれを却下する機会を与えてくれます
とにかくToastを表示するために、あなたはそれをあなたがActivityでそれを行うのと同じ方法を行う必要があります（IntentServiceがあまりにもContextです）： Toast.makeText(this, description, Toast.LENGTH_LONG).show();
は、次のステップに従ってください、と 'どこかonHandleIntent'で乾杯を示しました。 – stkent
@stkentだから、onHandleIntentに単純なToastステートメントを書くだけですか？ –
ガイドがやったようにonHandleIntentを実装したのですが、何も起こっていません...？ –
