Question

我正在做有很多屏幕的仪表板应用程序。当用户告诉基于我需要打开 Activity 的语音命令时。我不知道从哪里开始 我已经完成了所有屏幕，我想实现语音搜索。我的应用程序屏幕是 Advances、Leaves、Recruitment、Permissions、Notifications 等示例:当用户说“预付款”时，它应该打开预付款屏幕。请帮助我。

1) 启动语音识别 Intent

2) 处理onActivityResult()中的返回数据，决定启动哪个activity

<强>1。启动语音识别 Intent

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Choose Activity");
startActivityForResult(intent, REQUEST_SPEECH);

<强>2。处理返回的数据

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
        if (requestCode == REQUEST_SPEECH){
            if (resultCode == RESULT_OK){
                ArrayList<String> matches = data
                    .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                if (matches.size() == 0) {
                    // didn't hear anything
                } else {
                    String mostLikelyThingHeard = matches.get(0);
                    // toUpperCase() used to make string comparison equal
                    if(mostLikelyThingHeard.toUpperCase().equals("ADVANCES")){
                        startActivity(new Intent(this, Advances.class));
                    } else if() {
                    }
                }
            }
        }

        super.onActivityResult(requestCode, resultCode, data);
    }
