我正在尝试构建一个语音控制的应用程序,该应用程序可以根据命令执行一些任务。
我还想在其中添加Google即时功能,这样,如果用户问一些有关天气信息,新闻,名人等问题,那么我就可以从Google即时获得结果。

有什么方法可以在我的应用程序中集成G​​oogle Now功能?

您可以如下实现:

在负责触发语音 Intent 的按钮的单击事件上编写以下代码。

/**
 * Instruct the app to listen for user speech input
 */
private void listenToSpeech() {
    //start the speech recognition intent passing required data
    Intent listenIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    //indicate package
    listenIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass().getPackage().getName());
    //message to display while listening
    listenIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say a word!");
    //set speech model
    listenIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    //specify number of results to retrieve
    listenIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
    //start listening
    startActivityForResult(listenIntent, VR_REQUEST);
}

当 Intent 回叫时,我们将显示转录的语音。
/**
 * onActivityResults handles:
 *  - retrieving results of speech recognition listening
 *  - retrieving result of TTS data check
 */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    //check speech recognition result
    if (requestCode == VR_REQUEST && resultCode == RESULT_OK)
    {
        //store the returned word list as an ArrayList
        ArrayList<String> suggestedWords = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
        //set the retrieved list to display in the ListView using an ArrayAdapter
        wordList.setAdapter(new ArrayAdapter<String> (this, R.layout.word, suggestedWords));

     //to open the result in browser
     Intent intent = new Intent(Intent.ACTION_VIEW,
     Uri.parse("https://www.google.co.in/?gws_rd=cr#q="+suggestedWords));
startActivity(intent);
    }
    //tss code here
    //call superclass method
    super.onActivityResult(requestCode, resultCode, data);
}
