我被困在一个特殊的场景中.用户从应用程序更新时间后,我需要立即更新我的小部件.我确实通过发送Intent Extras数据来尝试广播,但是没有这样做.当前,我的数据存储在AppWidgetProvider中,我需要将此数据发送到服务
公共类CountdownWidget扩展了AppWidgetProvider {
????// SharedPreferences userDefaults;
// update rate in milliseconds
public static final int UPDATE_RATE = 1800000; // 30 minute
public static String nameOne = "";
@Override
public void onDeleted(Context context, int[] appWidgetIds) {
for (int appWidgetId : appWidgetIds) {
setAlarm(context, appWidgetId, -1);
}
super.onDeleted(context, appWidgetIds);
}
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle extras = intent.getExtras();
nameOne = extras.getString("NAME_ONE");
Log.e("Name: ", nameOne);
super.onReceive(context, intent);
}
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
for (int appWidgetId : appWidgetIds) {
setAlarm(context, appWidgetId, UPDATE_RATE);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
public static void setAlarm(Context context, int appWidgetId, int updateRate) {
// Log.e("", "Updating Widget Service");
PendingIntent newPending = makeControlPendingIntent(context,
CountdownService.UPDATE, appWidgetId);
AlarmManager alarms = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
if (updateRate >= 0) {
alarms.setRepeating(AlarmManager.ELAPSED_REALTIME,
SystemClock.elapsedRealtime(), updateRate, newPending);
} else {
// on a negative updateRate stop the refreshing
alarms.cancel(newPending);
}
}
public static PendingIntent makeControlPendingIntent(Context context,
String command, int appWidgetId) {
Intent active = new Intent(context, CountdownService.class);
active.setAction(command);
active.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
// this Uri data is to make the PendingIntent unique, so it wont be
// updated by FLAG_UPDATE_CURRENT
// so if there are multiple widget instances they wont override each
// other
Uri data = Uri.withAppendedPath(
Uri.parse("countdownwidget://widget/id/#" + command
+ appWidgetId), String.valueOf(appWidgetId));
active.setData(data);
return (PendingIntent.getService(context, 0, active,
PendingIntent.FLAG_UPDATE_CURRENT));
}
}
如您所见,nameOne是一个静态变量.我可以使用getExtras在onReceive方法上接收数据,但是我无法将这些数据传递给CountdownService服务.
我确实尝试了CountdownWidget.nameOne,但仍然无法满足服务中的数据要求.
任何帮助将不胜感激.
