如果 ContentProvider 的访问者需要知道 ContentProvider 中的数据发生了变化，可以在 ContentProvider 发生数据 变化时调用 getContentResolver().notifyChange(uri, null) 来通知注册在此 URI 上的访问者，例子如下：

public class PersonContentProvider extends ContentProvider {

public Uri insert(Uri uri, ContentValues values) {

db.insert("person", "personid", values);

getContext().getContentResolver().notifyChange(uri, null);

}

}
