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); })
