执行完成后关闭Realm实例

Question

我想executeTransactionAsync在执行完毕后关闭我的Realm实例.原因是我的应用程序主线程一直在冻结,我认为它的原因是后台域实例在执行完成后没有被关闭.请参阅下面的代码:

realm.executeTransactionAsync(new Realm.Transaction() {
                    @Override
                    public void execute(Realm realm) {
                        // Execute realm code
                        realm.copyToRealmOrUpdate(myData);
                        // Can I close the realm instance here without getting an 
                        // error? realm.close(); causes an error.
                    }
                }, new Realm.Transaction.OnSuccess() {
                    @Override
                    public void onSuccess() {
                        Log.i("CB", "success");
                        // looks like I cannot access the execute Realm 
                        // instance here.
                        // Closing realm.getDefaultInstance does not change my issue
                    }
                }, new Realm.Transaction.OnError() {
                    @Override
                    public void onError(Throwable error) {
                        Log.i("CB", "error - " + error.getMessage());
                    }
                });
            }

请看我的评论.我的应用程序屏幕变黑了.执行成功完成onSuccess()并被调用,但我无法访问execute领域实例以从此处关闭它.

你有什么建议可以尝试吗？难道我做错了什么？

先感谢您.

这是我的onSuccess被调用后的logcat.我认为领域的后台实例execute因某些原因而继续运行:(.

在这里传递的领域实例

@Override
public void execute(Realm realm) {

对你来说是封闭的.您不必担心自己关闭它.

如果您检查Realm.executeTransactionAsync()的源代码,您可以找到

bgRealm.beginTransaction();
try {
    transaction.execute(bgRealm);

    if (!Thread.currentThread().isInterrupted()) {
        bgRealm.commitTransaction(false, new Runnable() {
            @Override
            public void run() {
                // The bgRealm needs to be closed before post event to caller's handler to avoid
                // concurrency problem. eg.: User wants to delete Realm in the callbacks.
                // This will close Realm before sending REALM_CHANGED.
                bgRealm.close();
            }
        });
        transactionCommitted = true;
    }
}
...

所以首先它调用.execute()你的事务,然后关闭它传递给你的域实例.
