Android的 - 如何得到通知时同步完成后，请求与ContentResolver.requestSync同步（时） [英] Android - how to get notified when sync finishes, when requesting a sync with ContentResolver.requestSync()

问题描述

我有自己的的ContentProvider 和 SyncAdapter 这两个做工精细。

I have my own ContentProvider and SyncAdapter which both work fine.

我将它们设置为与 ContentResolver.setSyncAutomatically（）的这项工作被自动同步。我还可以开发工具测试同步 - >同步测试仪

I set them to be automatically synced with ContentResolver.setSyncAutomatically() an this work. I can also test the sync with Dev Tools -> Sync Tester.

现在我想从我的应用程序请求同步（如果我们没有数据还），当它完成通知，这样我就可以更新了界面（我展示一个进度条带标志，而它的同步）。我与 ContentResolver.requestSync（）这样做，但我还没有找到一种方式来获得通知时同步完成。

Now I would like to request a sync from my app (if we have no data yet) and be notified when it finishes, so I can updated the interface (I'm showing a progress bar with logo while it's syncing). I'm doing this with ContentResolver.requestSync(), but I have not found a way to get notified when the sync finishes.

有谁知道如何做到这一点？谢谢你。

Does anyone know how to do this? Thanks.

推荐答案

使用<一个href=\"http://developer.android.com/reference/android/content/ContentResolver.html#addStatusChangeListener%28int,%20android.content.SyncStatusObserver%29\"相对=nofollow> addStatusChangeListener（） 会给你回调时，同步是 SYNC_OBSERVER_TYPE_ACTIVE 或 SYNC_OBSERVER_TYPE_PENDING 。这是非常奇怪的是没有完成的事件。

Using addStatusChangeListener() will give you callbacks when the sync is SYNC_OBSERVER_TYPE_ACTIVE or SYNC_OBSERVER_TYPE_PENDING. It is well weird that there is no finished event.

下面是一个解决方法通过菲利克斯建议。他建议，你应该沟 ContentResolver的赞成广播。

Here is a workaround suggested by Felix. He suggests that you should ditch the ContentResolver in favour of Broadcasts.
