Phonegap Android 后退按钮 - 在主页上使用后退按钮关闭应用程序

问题描述:

我正在使用 Jquery Mobile/Phonegap 开发一个 Android 应用程序.我有以下代码来控制手机的后退按钮:

I am developing a Android app using Jquery Mobile/Phonegap. I have the following code to control the phone's back button:

document.addEventListener("backbutton", backKeyDown, true); 


function backKeyDown() { 
    // Call my back key code here.
    $.mobile.changePage("#homepage", "slideup");
}

这一切正常,但我希望应用程序仅在按下主页上的后退按钮时关闭,这可能吗?

This all works fine, but I would like the app to close when pressing the back button on the homepage only, is this possible?

更新:这已停止使用最新的 Phonegap 更新(据说).如果您知道,请随时提供可行的解决方案.

这是我的做法:

document.addEventListener("backbutton", function(e){
    if($.mobile.activePage.is('#homepage')){
        /* 
         Event preventDefault/stopPropagation not required as adding backbutton
          listener itself override the default behaviour. Refer below PhoneGap link.
        */
        //e.preventDefault();
        navigator.app.exitApp();
    }
    else {
        navigator.app.backHistory()
    }
}, false);
