如何让js函数SpeechRecognizer听者的反应？ [英] How to get SpeechRecognizer listner response in js function?

问题描述

我的工作SpeechRecognizer听者的活动。

I am working on SpeechRecognizer Listner activity.

我从网页视图按钮点击触发的意图（startListning（意向））扔的JavaScript

I am triggering the intent (startListning(intent)) from Webview button click threw javascript

act.startFun();

而startFun（）方法是在我MainActivity.java文件中声明

And the startFun() method is declared in my MainActivity.java file

public void startFun(){
        Log.d(TAG,"ONCLICK");
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);         
 intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
         intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test");
         intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,5); 
         sr.startListening(intent);
   }

和我SpeechRecognizer听者犹如

and my SpeechRecognizer Listner is like

class listner implements RecognitionListener{  
            public void onResults(Bundle results) {
            end=1;
            Log.d(TAG, "onResults");
        }

        public void onRmsChanged(float rmsdB) {
            Log.d(TAG, "onRmsChanged");
        }
    }

我的要求是我想通过onResults（捆绑的结果）的结果字符串到我的JavaScript方法。

My requirement is i want to pass the onResults(Bundle results) 's result string to my javascript method.

请有人帮助我实现这一目标。

Please some one help me to achieve this.

推荐答案

有一个变量传递给JavaScript函数没有简单的方法......但是你可以
创建一个类JavaScriptInterface和信号JavaScript的，当你拥有它准备好字符串。

There's no easy way to pass a variable to a JavaScript function... but you could create a class JavaScriptInterface and signal the JavaScript to get the string when you have it ready.

webview.addJavascriptInterface(new JavaScriptInterface(),"Interface");

列出要在JavaScriptInterface类调用的函数。
然后，在JavaScript ...

list the functions you want to call in the JavaScriptInterface class. Then in your javascript...

Interface.getStringResult();

您也可以创建一个函数来检查，看看是否在JavaScript中存在的接口：

You can also create a function to check to see if the interface exists in JavaScript:

function runningInAndroidApp() {
    if (typeof Interface != 'undefined') {
        return true;
    }
    return false;
}
