在windows系统上python idle使用kivy框架开发应用，写一个界面按下“开始录音”的按钮时调用百度api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；并给出“连接蓝牙””加载样品溶液““加载清洗液一““加载清洗液二”“加载洗脱溶液”“总操作”按钮的正确代码

以下是代码示例，其中需要填写自己的百度API的APP_ID、API_KEY和SECRET_KEY：

import kivy
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.textinput import TextInput
from kivy.uix.button import Button
from aip import AipSpeech
import bluetooth

class MyBoxLayout(BoxLayout):
    def __init__(self, **kwargs):
        super(MyBoxLayout, self).__init__(**kwargs)
        self.orientation = 'vertical'
        self.padding = 20
        self.spacing = 10

        # 创建文本框和按钮
        self.text_input = TextInput(multiline=True, font_size=20)
        self.start_button = Button(text='开始录音', size_hint=(1, 0.2), font_size=20)
        self.clear_button = Button(text='清空', size_hint=(1, 0.2), font_size=20)

        # 将按钮与函数绑定
        self.start_button.bind(on_press=self.start_recognition)
        self.clear_button.bind(on_press=self.clear_text)

        # 将组件添加到布局中
        self.add_widget(self.text_input)
        self.add_widget(self.start_button)
        self.add_widget(self.clear_button)

    def start_recognition(self, instance):
        # 调用百度API进行语音识别
        APP_ID = '填写自己的APP_ID'
        API_KEY = '填写自己的API_KEY'
        SECRET_KEY = '填写自己的SECRET_KEY'
        client = AipSpeech(APP_ID, API_KEY, SECRET_KEY)
        result = client.asr(get_audio(), 'pcm', 16000, {'dev_pid': 1536})
        if result['err_no'] == 0:
            text = result['result'][0]
            self.text_input.text += text
        else:
            self.text_input.text += '识别失败'

    def clear_text(self, instance):
        self.text_input.text = ''

    def connect_bluetooth(self, instance):
        # 连接蓝牙设备
        addr = '填写蓝牙设备的MAC地址'
        port = 1
        sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
        sock.connect((addr, port))

    def load_sample_solution(self, instance):
        # 加载样品溶液
        pass

    def load_cleaning_solution_one(self, instance):
        # 加载清洗液一
        pass

    def load_cleaning_solution_two(self, instance):
        # 加载清洗液二
        pass

    def load_elution_solution(self, instance):
        # 加载洗脱溶液
        pass

    def total_operation(self, instance):
        # 总操作
        pass

class MyApp(App):
    def build(self):
        return MyBoxLayout()

if __name__ == '__main__':
    MyApp().run()

其中，需要自己填写百度API的APP_ID、API_KEY和SECRET_KEY，以及蓝牙设备的MAC地址和各种操作的具体实现。
