    App
    获取语⾳音输⼊入
    除了可以⽤用语⾳音操作启动activity，还可以获取⽤用户的语⾳音输⼊入内容并且处理它们，例如将语⾳音输⼊入内容作为搜索内容或者短信发送出
    去。
    调⽤用startActivityForResult()启动处理语⾳音识别的activity，并且intent设置action为ACTION_RECOGNIZE_SPEECH。
    并在activity中重写onActivityResult()⽅方法，来处理返回的语⾳音输⼊入结果。
    private static final int SPEECH_REQUEST_CODE = 0;
    private void displaySpeechRecognizer() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
    RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    startActivityForResult(intent, SPEECH_REQUEST_CODE);
    }
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) {
    List results = data.getStringArrayListExtra(
    RecognizerIntent.EXTRA_RESULTS);
    String spokenText = results.get(0);
    }
    super.onActivityResult(requestCode, resultCode, data);
    }
