NavigationGroup安卓在Titanium中

Question

嗨,我是钛的新手,允许开发人员创建跨平台的应用程序.我需要创建一个适用于Android和iOS的导航组.有没有明确的解决方案(因为Ti.UI.iPhone.createNavigationGrou()仅适用于iphone,

谢谢

Answer 1

我有以下NavigationController,它位于android和iphone文件夹中:

安卓

var NavigationController = function() {
    var self = this;

    self.open = function(windowToOpen) {
        //make "heavyweight" and associate with an Android activity
        windowToOpen.navBarHidden = windowToOpen.navBarHidden || false;

        if(!self.rootWindow) {
            windowToOpen.exitOnClose = true;
            self.rootWindow = windowToOpen;
        }

        windowToOpen.open();
    };

    self.close = function(windowToClose) {
        windowToClose.close();
    };

    return self;
};

module.exports = NavigationController;

苹果手机

var NavigationController = function() {
    var self = this;

    function createNavGroup(windowToOpen) {
        self.navGroup = Ti.UI.iPhone.createNavigationGroup({
            window : windowToOpen
        });
        var containerWindow = Ti.UI.createWindow();
        containerWindow.add(self.navGroup);
        containerWindow.open();
    };

    self.open = function(windowToOpen) {
        if(!self.navGroup) {
            createNavGroup(windowToOpen);
        }
        else {
            self.navGroup.open(windowToOpen);
        }
    };

    self.close = function(windowToClose) {
        if(self.navGroup) {
            self.navGroup.close(windowToClose);
        }
    };

    return self;
};

module.exports = NavigationController;

然后,您可以使用它(您将根据您的运行时自动获得正确的):

var NavigationController = require('NavigationController')
var MyView = require("ui/MyView");

var controller = new NavigationController();
var myView = new MyView(controller);
controller.open(myView);

您可以继续打开窗口,然后进入堆栈.注意我将控制器传递给第一个视图.你继续这样做:

controller.open(new SecondView(controller));

该back按钮会自动将物品从堆叠中移开.如果您需要以编程方式执行此操作,只需告诉控制器将其关闭:

controller.close(myView);
