Realm.io [Java]通知 - 如何仅在某些表中监听更改？ [英] Realm.io [Java] notifications - How to listen for changes only in certain Table?

问题描述

我在realm java文档中看到这个示例代码。

I see this example code in realm java documentation.

public class MyActivity extends Activity {
    private Realm realm;
    // A reference to RealmChangeListener needs to be held to avoid being
    // removed by the garbage collector.
    private RealmChangeListener realmListener;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      realm = Realm.getDefaultInstance();
      reamlListener = new RealmChangeListener() {
        @Override
        public void onChange() {
            // ... do something with the updates (UI, etc.) ...
        }};
      realm.addChangeListener(realmListener);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        // Remove the listener.
        realm.removeChangeListener(realmListener);
        // Close the realm instance.
        realm.close();
    }
}

我有一些数据库模式包含几个表。数据总是在这些表中改变，但我只有一个表，我需要监听和刷新UI与这个表相关。我不想检查这是在Realm的更改在任何其他Realm对象中的任何小更新后完全在期望表。
您可以建议哪些最佳做法？

I have some database schema contain several tables. Data is always changing in these tables but I have only the one table I need to listen and refresh UI related to this table. I don't want to check is this changes in Realm was exactly in wanted table after any little updating in any other Realm Objects. What best practices can you suggest?

推荐答案

直到Realm具有精细粒度的通知，系统，通过使用ContentObserver，RxJava或您自己的Observer接口。

Until Realm has fine-grained notifications, I would implement my own notification system either by using ContentObserver, RxJava or your own Observer interfaces.
