我使用的是一个没有Map的类，因此用户在输入已经建立的地理围栏之前不能单击某个按钮。我使用的是广播接收器，目前只能在用户进入区域时向其显示祝酒词，但我希望它更复杂一点，因为原始类中的元素在用户进入geofence时会发生变化。

public class GeofenceBroadcastReceiver extends BroadcastReceiver {

    private static final String TAG = "GeofenceBroadcastReceiv";

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        Toast.makeText(context, "Geofence triggered...", Toast.LENGTH_SHORT).show();

        NotificationHelper notificationHelper = new NotificationHelper(context);

        GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);

        if (geofencingEvent.hasError()) {
            Log.d(TAG, "onReceive: Error receiving geofence event...");
            return;
        }

        List<Geofence> geofenceList = geofencingEvent.getTriggeringGeofences();
        for (Geofence geofence: geofenceList) {
            Log.d(TAG, "onReceive: " + geofence.getRequestId());
        }
//        Location location = geofencingEvent.getTriggeringLocation();
        int transitionType = geofencingEvent.getGeofenceTransition();

        switch (transitionType) {
            case Geofence.GEOFENCE_TRANSITION_ENTER:
                Toast.makeText(context, "GEOFENCE_TRANSITION_ENTER", Toast.LENGTH_SHORT).show();
                notificationHelper.sendHighPriorityNotification("GEOFENCE_TRANSITION_ENTER", "", MapsActivity.class);
                break;
            case Geofence.GEOFENCE_TRANSITION_DWELL:
                Toast.makeText(context, "GEOFENCE_TRANSITION_DWELL", Toast.LENGTH_SHORT).show();
                notificationHelper.sendHighPriorityNotification("GEOFENCE_TRANSITION_DWELL", "", MapsActivity.class);
                break;
            case Geofence.GEOFENCE_TRANSITION_EXIT:
                Toast.makeText(context, "GEOFENCE_TRANSITION_EXIT", Toast.LENGTH_SHORT).show();
                notificationHelper.sendHighPriorityNotification("GEOFENCE_TRANSITION_EXIT", "", MapsActivity.class);
                break;
        }

    }
}

抱歉，如果这说不通的话，我是个新手；）
