听Android的日历变化。 (同步/删除/插入等。) [英] Listen to android calendar changes. (Sync/Delete/Insert etc..)
本文介绍了听Android的日历变化。 (同步/删除/插入等。)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我已经明白,我必须使用内容提供商
来让所有的变化,但我也意识到启动 API14
有一个现成的内容提供商
的,我可以用它来听,而不是建设自己的自定义的日历。
是否有任何地方,我可以看到这样的例子?
有人可以请张贴这个监听器的核心是什么?
I've understand I have to use Content Provider
to get all changes, but I also realized starting API14
there is a ready Content Provider
for the calendar which I can use to listen to instead of "building" my own custom one.
Is there anywhere I can see an example of this ?
Can someone please post the core of this listener ?
感谢
推荐答案
首先,你需要这种类型的接收器添加到清单:
First you need to add this type of receiver to the Manifest:
<receiver android:name="your.package.name.CatchChangesReceiver"
android:priority="1000" >
<intent-filter>
<action android:name="android.intent.action.PROVIDER_CHANGED" />
<data android:scheme="content" />
<data android:host="com.android.calendar" />
</intent-filter>
</receiver>
然后创建延伸广播接收器一个简单的类:
Then create a simple class which extends broadcast receiver:
public class CatchChangesReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// add processing here with some query to content provider
// in my project I use this selection for getting events:
final String SELECTION = CalendarContract.Events.CALENDAR_ID + "="
+ calendarId + " AND " + "("
+ CalendarContract.Events.DIRTY + "=" + 1 + " OR "
+ CalendarContract.Events.DELETED + "=" + 1 + ")" + " AND "
+ CalendarContract.Events.DTEND + " > "
+ Calendar.getInstance().getTimeInMillis();
}
}
