Android实现widget定时更新

核心提示：int appWidgetId=getNextWidgetId();List listNews = NewsContenttList.getNewsList(updateUrl);if (listNews != null) {updateViews = NewsWidgetProvider.updateAppWidge

int appWidgetId=getNextWidgetId();

List listNews = NewsContenttList.getNewsList(updateUrl);

if (listNews != null) {

updateViews = NewsWidgetProvider.updateAppWidget(this, listNews);

}

if (updateViews != null) {

appWidgetManager.updateAppWidget(appWidgetId, updateViews);

}

}

Intent updateIntent=new Intent(ACTION_UPDATE_ALL);

updateIntent.setClass(this, NewsService.class);

PendingIntent pending=PendingIntent.getService(this, 0, updateIntent, 0);

Time time = new Time();

long nowMillis = System.currentTimeMillis();

time.set(nowMillis+Long.parseLong(updateTime));

long updateTimes = time.toMillis(true);

Log.d(TAG, "request next update at "+updateTimes);

AlarmManager alarm=(AlarmManager)getSystemService(Context.ALARM_SERVICE);

alarm.set(AlarmManager.RTC_WAKEUP, updateTimes, pending);

stopSelf();

}

}

这个只是我的情况，如果大家有不一样的情况，稍微修改即可。
