text to speech

Android studio–kotlin语言

直接上代码

MainActivity.kt

package cn.edu.zhouimport android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import android.widget.Button
import android.widget.EditText
import android.widget.Switchclass MainActivity : AppCompatActivity() {override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_main)val editText = findViewById(R.id.editText) as EditTextval aSwitch = findViewById(R.id.switch1) as Switchval button = findViewById(R.id.button) as Buttonbutton.setOnClickListener { TTS(this@MainActivity, editText.text.toString(), aSwitch.isChecked) }}
}

TTS.kt

这个是我新建的另一个activity文件（右击–New–Activity–Empty Activity）

package cn.edu.zhouimport android.app.Activity
import android.speech.tts.TextToSpeech
import android.widget.Toast
import java.util.*class TTS(private val activity: Activity,private val message: String,private val br: Boolean) : TextToSpeech.OnInitListener {private val tts: TextToSpeech = TextToSpeech(activity, this)override fun onInit(i: Int) {if (i == TextToSpeech.SUCCESS) {val localeBR = Locale("pt", "BR")val localeUS = Locale.USval result: Intresult = if (br) tts.setLanguage(localeBR) else tts.setLanguage(localeUS)if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {Toast.makeText(activity, "This Language is not supported", Toast.LENGTH_SHORT).show()} else {speakOut(message)}} else {Toast.makeText(activity, "Initilization Failed!", Toast.LENGTH_SHORT).show()}}private fun speakOut(message: String) {tts.speak(message, TextToSpeech.QUEUE_FLUSH, null, null)}
}

界面布局

activity_main.xml

软件截图

该软件可以读 汉字 英语 数字。
当PT-BR关闭时，数字读的是英文，如：1读作one。反之，为正常阿拉伯数字发音

以上代码把package cn.edu.zhou修改为自己的地址就可以执行
