Phonegap Android后退按钮 - 关闭应用程序与主页上的后退按钮 [英] Phonegap Android Back Button - close app with back button on homepage

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");
}

这一切都很好，但我想应用程序关闭时按

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

推荐答案

这是我的操作方式：

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);
