javascript - $ionicHistory.clearHistory 清除历史记录，但在 android 上单击 hardwareBackButton 时会转到上一个 View ？

Question

这是我的代码

.controller("HomeCtrl", function ($scope,$ionicHistory,SearchService) {

  $scope.history = $ionicHistory.viewHistory(); 
  $scope.clearhistory = function(){
    $ionicHistory.clearHistory();
    $scope.history = $ionicHistory.viewHistory();
  }
  
})


.state('eventmenu.home', {
  url: "/home",
  cache: false,
  views: {
    'menuContent' :{
      templateUrl: "templates/home.html",
      controller: "HomeCtrl"
    }
  }
})

ion-view title='<a href="#/event/home"><img class="title-image" src="img/acc.png" height = "40px" width = "120px"/></a>'>
  <ion-content class="padding" ng-hide="searchBarVisibility">
    <pre>{{history | json}}</pre>
    <button ng-click="clearhistory()">clear</button>
  </ion-content>
</ion-view>

我的应用程序中的同一 View 中有 10 个状态。第 10 个状态有一个到主页的链接。当我通过第 10 个状态进入主页时，{{history}} 显示遍历的所有状态，当我按下清除按钮时，所有历史记录也会被清除，我得到以下输出。

    "histories": {
    "root": {
      "historyId": "root",
      "parentHistoryId": null,
      "stack": [],
      "cursor": -1
    },
    "ion1": {
      "historyId": "ion1",
      "parentHistoryId": "root",
      "stack": [
        {
          "viewId": "ion33",
          "index": 1,
          "historyId": "ion1",
          "backViewId": null,
          "forwardViewId": null,
          "stateId": "eventmenu.home",
          "stateName": "eventmenu.home",
          "url": "/event/home",
          "canSwipeBack": true,
          "title": "<a href=\"#/event/home\"><img class=\"title-image\" src=\"img/acc.png\" height = \"40px\" width = \"120px\"/></a>"
        }
      ],
      "cursor": -1
    },
    "ion5": {
      "historyId": "ion5",
      "parentHistoryId": "root",
      "stack": [],
      "cursor": -1
    }
  },
  "views": {
    "ion33": {
      "viewId": "ion33",
      "index": 1,
      "historyId": "ion1",
      "backViewId": null,
      "forwardViewId": null,
      "stateId": "eventmenu.home",
      "stateName": "eventmenu.home",
      "url": "/event/home",
      "canSwipeBack": true,
      "title": "<a href=\"#/event/home\"><img class=\"title-image\" src=\"img/acc.png\" height = \"40px\" width = \"120px\"/></a>"
    }
  },
  "backView": null,
  "forwardView": null,
  "currentView": {
    "viewId": "ion33",
    "index": 1,
    "historyId": "ion1",
    "backViewId": null,
    "forwardViewId": null,
    "stateId": "eventmenu.home",
    "stateName": "eventmenu.home",
    "url": "/event/home",
    "canSwipeBack": true,
    "title": "<a href=\"#/event/home\"><img class=\"title-image\" src=\"img/acc.png\" height = \"40px\" width = \"120px\"/></a>"
  }

但是当我点击android的硬件按钮时，问题就出现了。应用程序再次遍历之前访问过的所有状态，而不是退出应用程序。并且当它返回到主页时，历史堆栈再次被填充。即使历史记录已被清除，为什么还会发生这种情况？如果历史记录被清除，我应该如何使应用程序在单击后退按钮后退出。

 $ionicPlatform.registerBackButtonAction(function () {
      if ($state.current.name == "signIn"){
        navigator.app.exitApp();
      } else {
        navigator.app.backHistory();
      }
    }, 100);
