推荐答案

有两种类型，如窗口， 轻量级和重量级。如果您在钛的android一个轻量级的窗口不是在后退按钮preSS会存在从应用程序。

There are two types of windows like, lightweight and heavyweight. If you create a lightweight window in Titanium android than on back button press it will exist from your application.

您可以实现你想要创建重量级窗口的内容。你可以打开它的模态窗口创建钛重量级窗口。所以，把参数模式：当您创建一个新的窗口真。新的窗口将被创建为模态窗口（窗口重量级钛机器人）。再后，如果你将preSS后退按钮也不会从申请退出。

You can achieve what you want by creating heavyweight window. You can create heavyweight window in titanium by open it as modal window. So put the parameter modal:true when you create a new window. New window will be created as modal window (heavyweight window for titanium android). And then after if you will press back button it will not exit from application.
