【问题描述】:
我有一个需要帮助的问题。我试图通过在前端使用角度控制器来调用 android 函数,但我无法让它工作。
主活动:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView)findViewById(R.id.activity_main_webview);
mWebView.setWebViewClient(new CustomWebViewClient());
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.addJavascriptInterface(new AngularJSInterface(this), "Android");
mWebView.loadUrl("http://192.168.70.101:3000/");
}
AngularJS接口:
public class AngularJSInterface {
Context mContext;
AngularJSInterface(Context c) {
mContext = c;
}
public void showToast(String toast) {
Toast.makeText(mContext, toast, Toast.LENGTH_SHORT).show();
}
}
角度控制器:
angular.module('app').controller('ComplaintCtrl', function ($scope, $http, complaintService) {
$scope.showToast = function(toast) {
Android.showToast(toast);
console.log("toast");
}
});
HTML:
<button label="toast" ng-click="showToast('Visar toast från angularJS')">toast</button>
来自控制台的错误:
ReferenceError: Android is not defined
at Scope.$scope.showToast (http://localhost:3000/scripts/controllers/addcomplaint.js:34:3)
at http://localhost:3000/bower_components/angular/angular.js:10567:21
at http://localhost:3000/bower_components/angular-touch/angular-touch.js:438:9
at Scope.$eval (http://localhost:3000/bower_components/angular/angular.js:12412:28)
at Scope.$apply (http://localhost:3000/bower_components/angular/angular.js:12510:23)
at HTMLButtonElement.<anonymous> (http://localhost:3000/bower_components/angular-touch/angular-touch.js:437:13)
at HTMLButtonElement.jQuery.event.dispatch (http://localhost:3000/bower_components/jquery/dist/jquery.js:4409:9)
at HTMLButtonElement.elemData.handle (http://localhost:3000/bower_components/jquery/dist/jquery.js:4095:28)
这是我第一次使用这种东西,我不太确定如何实际使用它。我尝试通过谷歌搜索寻找答案,但没有运气。我做错了什么?
