这就是我为我的小部件安排更新的方式。每个都允许是唯一的,因为它们具有唯一的小部件 ID 号。
Intent widgetUpdate = new Intent();
widgetUpdate.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
widgetUpdate.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, new int[] { appWidgetId });
widgetUpdate.putExtra(EXTRA_POSITION,0);
widgetUpdate.putExtra(EXTRA_URL, URL);
// make this pending intent unique by adding a scheme to it
widgetUpdate.setData(Uri.withAppendedPath(Uri.parse(URI_SCHEME + "://widget/id/"), String.valueOf(appWidgetId)));
PendingIntent newPending = PendingIntent.getBroadcast(context, 0, widgetUpdate, PendingIntent.FLAG_UPDATE_CURRENT);
// schedule the updating
AlarmManager alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarms.setRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime(), updateRateSeconds * 1000, newPending);
