我有一个问题,我需要一些帮助。我试图通过在我的前端使用角度控制器来调用android函数,但我无法让它工作。
MainActivity:
@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/");
}
AngularJSInterface:
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>
控制台出错:
ReferenceError: Android is not defined

这是我第一次使用这种东西而且我不太确定如何实际操作。我试过通过谷歌搜索寻找答案,但没有运气。我做错了什么?
答案 0 :(得分:0)
将您的toast函数更改为static并直接调用它或首先实例化它。而且,您没有名为Android
的类,而是创建了AngularJSInterface
。将您Android.showToast
更改为AngularJSInterface.showToast
(如果使用静态)。
