windows系统下Android studio使用Java语言调用百度api写语音控制程序，在界面按下“开始录音”的按钮时开始录音并识别，同时在文本框中展现识别结果，按下”清空”按钮清除文本框内容；当识别出“你好”或者按下界面上的”你好“按钮时首次通过无线蓝牙通过无线传输的方式而不用USB-TTL接口向hc-05型号的蓝牙发送字母a，识别出“好天“的时候通过蓝牙发送字母b代码生成

以下是一个示例代码，仅供参考：

        super("Speech Recognition Demo");
        setSize(400, 200);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JPanel panel = new JPanel();
        JLabel lblResult = new JLabel("Result:");

        txtResult.setEditable(false);
        btnStart = new JButton("Start Recording");
        btnClear = new JButton("Clear");
        btnHello = new JButton("Say Hello");
        btnGood = new JButton("Say Good");

        panel.add(lblResult);
        panel.add(txtResult);
        panel.add(btnStart);
        panel.add(btnClear);
        panel.add(btnHello);

        add(panel);

        btnStart.addActionListener(this);

        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == btnStart) {
            startRecording();
        } else if (e.getSource() == btnClear) {
            txtResult.setText("");
        } else if (e.getSource() == btnHello) {
            sendBluetoothCommand('a');
        } else if (e.getSource() == btnGood) {
            sendBluetoothCommand('b');
        }
    }

    private void startRecording() {
        try {
            JSONObject result = BaiduAPI.speechRecognition(line);
            String text = result.optString("result", "");
            txtResult.setText(text);
            if (text.contains("你好")) {
                sendBluetoothCommand('a');
            } else if (text.contains("好天")) {
                sendBluetoothCommand('b');
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private void sendBluetoothCommand(char command) {
        // TODO: 实现通过蓝牙发送命令的代码
    }

    public static void main(String[] args) {
        new SpeechRecognitionDemo();
    }
}

class BaiduAPI {
    private static final String APP_ID = "your app id";
    private static final String API_KEY = "your api key";
    private static final String SECRET_KEY = "your secret key";

    public static JSONObject speechRecognition(TargetDataLine line) throws Exception {
        // 保存录音文件
        File file = new File("record.wav");
        AudioSystem.write(new AudioInputStream(line), AudioFileFormat.Type.WAVE, file);

        // 调用百度语音识别API
        AipSpeech client = new AipSpeech(APP_ID, API_KEY, SECRET_KEY);
        byte[] data = FileUtils.readFileToByteArray(file);
        JSONObject result = client.asr(data, "wav", 16000, null);
        return result;
    }
}

需要注意的是，该代码中需要调用百度语音识别的API，因此需要引入相应的依赖包。同时，还需要实现通过蓝牙发送命令的代码，这部分需要根据具体的蓝牙设备和通信协议进行实现。
