问题描述
我已经在这个主题上进行了很多搜索，查找了Jython和Chaquopy之类的选项，但是无论我做什么，总是有错误。
我想要做的是，当单击我的Android应用上的按钮时，python脚本（使用python中的gTTS API进行语音识别）将运行。
这是我的代码（使用Chaquopy）的样子：
MainActivity.java：
import androidx.appcompat.app.AppCompatActivity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.ImageButton;
import android.content.res.AssetFileDescriptor;
import com.chaquo.python.*;
import com.chaquo.python.android.Androidplatform;
import java.io.IOException;
public class MainActivity extends AppCompatActivity implements View.OnTouchListener{
ImageButton AutoCruiseButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (!Python.isstarted()) {
Python.start(new Androidplatform(this));
}
AutoCruiseButton = (ImageButton) findViewById(R.id.auto);
AutoCruiseButton.setonTouchListener(this);
final MediaPlayer beep1 = MediaPlayer.create(this,R.raw.beep1);
final MediaPlayer mp = new MediaPlayer();
AutoCruiseButton.setonClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
stopAndplay(R.raw.beep1,mp);
Python python = Python.getInstance();
PyObject file = python.getModule("voice_recognition");
PyObject command = file.callAttr("myCommand");
}
});
顶级构建文件：build.gradle
buildscript {
repositories {
google()
jcenter()
maven { url "https://chaquo.com/maven" }
}
dependencies {
classpath 'com.android.tools.build:gradle:4.0.2'
classpath "com.chaquo.python:gradle:8.0.0"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {

jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir

androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}
voice_recognition.py（位于Android Studio项目主文件夹下的python文件夹中）：
from gtts import gTTS
import speech_recognition as sr
import playsound
import sys
counter = 0
def myCommand():
r = sr.Recognizer()
global counter
if counter == 0:
playsound.playsound('C:/Users/Alya/Desktop/KITT/Audio_Clips/What_Can_I_Do.mp3')
with sr.Microphone() as source:
counter += 1
print('I am ready for your next command')
r.pause_threshold = 1
r.adjust_for_ambient_noise(source,duration=1)
audio = r.listen(source)
try:
command = r.recognize_google(audio)
print('You said ' + command + '\n')
#loop back in case not understood
except sr.UnkNownValueError:
print("I didn't hear that")
command = ""
playsound.playsound('C:/Users/Alya/Desktop/KITT/Audio_Clips/Go_Ahead.mp3')
assistant(myCommand())
return command
#if statements for executing commands
def assistant(command):
if 'introduce yourself' in command:
playsound.playsound('C:/Users/Alya/Desktop/KITT/Audio_Clips/KITT_Intro.mp3')
我知道Chaquopy可以工作，因为我测试了基本的python文件，并且模拟器没有崩溃。这是我单击按钮运行python脚本时遇到的错误：

关于如何进行的任何建议？我真的宁愿将我的Android应用程序保留在Java中，因为该接口已经实现。如何修复我的代码，使其与Chaquopy兼容？或者，如果它是更好的选择，我将如何在Jython中做到呢？
