重构包含无参数方法的 switch 语句 [英] Refactoring switch statement containing methods with no parameters

问题描述

我目前正在重构我的代码并被阻止.我有一个 switch 语句，我只知道可以重构，我只是缺乏这样做的经验:( 处理开关的大多数模式和方法侧重于管理不同方法的参数，但是情况并非如此.有什么想法我可以做些什么吗?非常感谢任何提示.

I'm currently refactoring my code and got blocked. I have a switch statement that I just know that can be refactored, I just have lack of experience to do so :( Most of patterns and ways of dealing with switches focus of managing parameters which differs methods, but it's not the case here. Any ideas what can I do about it? Would really appreciate any hints.

public void manageMenuAction(MenuItem item, GiftListPresenterViewConnector activityConnector) {
    switch (item.getItemId()) {
        case R.id.nav_your_account:
            activityConnector.goToEditAccount();
            break;
        case R.id.help:
            activityConnector.goToHelpScreen();
            break;
        case R.id.nav_about:
            createInfoDialog();
            break;
        case R.id.nav_exit:
            activityConnector.exitApp();
            break;
        case R.id.nav_logout:
            clearLocalData();
            activityConnector.logout();
            break;
    }
}

我正在为 Android 编写代码，因此使用 java 1.7.GiftListPresenterViewConnector 是一个接口.

I'm coding for Android, so working with java 1.7. GiftListPresenterViewConnector is an interface.
