一、准备Toast插件插件地址：cordova plugin add https://github.com/EddyVerbruggen/Toast-PhoneGap-Plugin.git二：代码

.run(function ($ionicPlatform, $rootScope, $location, $timeout, $ionicHistory, $cordovaToast) {        $ionicPlatform.ready(function ($rootScope) {            // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard            // for form inputs)            if (window.cordova && window.cordova.plugins.Keyboard) {                cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);            }            if (window.StatusBar) {                // org.apache.cordova.statusbar required                StatusBar.styleDefault();            }        });        //双击退出        $ionicPlatform.registerBackButtonAction(function (e) {            //判断处于哪个页面时双击退出            if ($location.path() == '/tab/news') {                if ($rootScope.backButtonPressedOnceToExit) {                    ionic.Platform.exitApp();                } else {                    $rootScope.backButtonPressedOnceToExit = true;                    $cordovaToast.showShortTop('再按一次退出系统');                    setTimeout(function () {                        $rootScope.backButtonPressedOnceToExit = false;                    }, 2000);                }            }            else if ($ionicHistory.backView()) {                $ionicHistory.goBack();            } else {                $rootScope.backButtonPressedOnceToExit = true;                $cordovaToast.showShortTop('再按一次退出系统');                setTimeout(function () {                    $rootScope.backButtonPressedOnceToExit = false;                }, 2000);            }            e.preventDefault();            return false;        }, 101);    })
