python idle使用kivy框架打包手机应用，在手机界面按下“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；当识别出“加载样品溶液”或者按下界面上的”加载样品溶液“按钮时调用手机api蓝牙向hc-05型号的蓝牙发送字母a，识别出“加载清洗液一“的时候通过蓝牙发送字母b；识别出“加载清洗液二”或按下按钮的时候发送字母c，识别出“加载洗脱溶液”时发送字母d，按下“总操作”的按钮时发送字母e完整代码生成

由于代码较长，无法在此处完整展示，请参考以下代码：

import os
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import ObjectProperty
from kivy.lang import Builder
import speech_recognition as sr
import serial

# 通过Builder.load_file加载.kv文件
Builder.load_file("app.kv")

class MainApp(App):
    def build(self):
        return RootWidget()

class RootWidget(BoxLayout):
    # 获取文本框对象
    txt_input = ObjectProperty(None)

    def __init__(self, **kwargs):
        super(RootWidget, self).__init__(**kwargs)
        self.recognizer = sr.Recognizer()
        self.microphone = sr.Microphone()
        self.ser = serial.Serial('/dev/tty.HC-05-DevB', 9600, timeout=1)

    def on_start_recording(self):
        with self.microphone as source:
            self.recognizer.adjust_for_ambient_noise(source)
            audio = self.recognizer.listen(source)

        try:
            text = self.recognizer.recognize_baidu(audio, appid='xxx', api_key='xxx', secret_key='xxx')
            self.txt_input.text = text
            if "加载样品溶液" in text:
                self.ser.write(b'a')
            elif "加载清洗液一" in text:
                self.ser.write(b'b')
            elif "加载清洗液二" in text:
                self.ser.write(b'c')
            elif "加载洗脱溶液" in text:
                self.ser.write(b'd')
        except sr.UnknownValueError:
            print("Baidu Speech Recognition could not understand audio")
        except sr.RequestError as e:
            print(f"Could not request results from Baidu Speech Recognition service; {e}")

    def on_clear_text(self):
        self.txt_input.text = ""

    def on_load_sample_solution(self):
        self.ser.write(b'a')

    def on_load_cleaning_solution1(self):
        self.ser.write(b'b')

    def on_load_cleaning_solution2(self):
        self.ser.write(b'c')

    def on_load_elution_solution(self):
        self.ser.write(b'd')

    def on_total_operation(self):
        self.ser.write(b'e')

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

同时，需要在同级目录下新建一个名为`app.kv`的文件，并添加以下代码：

<RootWidget>:
    BoxLayout:
        orientation: "vertical"
        TextInput:
            id: txt_input
            readonly: True
        BoxLayout:
            size_hint_y: None
            height: "48dp"
            Button:
                text: "开始录音"
                on_release: root.on_start_recording()
            Button:
                text: "清空"
                on_release: root.on_clear_text()
        BoxLayout:
            size_hint_y: None
            height: "48dp"
            Button:
                text: "加载样品溶液"
                on_release: root.on_load_sample_solution()
            Button:
                text: "加载清洗液一"
                on_release: root.on_load_cleaning_solution1()
            Button:
                text: "加载清洗液二"
                on_release: root.on_load_cleaning_solution2()
            Button:
                text: "加载洗脱溶液"
                on_release: root.on_load_elution_solution()
        BoxLayout:
            size_hint_y: None
            height: "48dp"
            Button:
                text: "总操作"
                on_release: root.on_total_operation()

请注意，代码中的`appid`、`api_key`、`secret_key`需要自己到百度API平台申请并填写。此外，代码中的`/dev/tty.HC-05-DevB`是串口号，需要根据实际情况进行更改。
