Android 11 使用 TextToSpeech 实现文字转换语音 && 相关 bug:speak failed: not bound to TTS engine

代码

MainActivity.javapackagecom.example.myapplication;

importandroidx.appcompat.App.AppCompatActivity;

importAndroid.content.Intent;

importAndroid.os.Bundle;

importAndroid.speech.tts.TextToSpeech;

importAndroid.text.TextUtils;

importAndroid.util.Log;

importAndroid.view.View;

importAndroid.widget.Button;

importAndroid.widget.EditText;

importAndroid.widget.Toast;

importjava.util.Locale;

publicclassMainActivityextendsAppCompatActivity{

privateEditTextmain_edit_text;

privateTextToSpeechmTextToSpeech;

@Override

protectedvoidonCreate(BundlesavedInstanceState){

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

main_edit_text=(EditText)findViewById(R.id.message);

mTextToSpeech=newTextToSpeech(this,newTextToSpeech.OnInitListener(){

@Override

publicvoidonInit(intstatus){// 初始化 tts

if(status==TextToSpeech.SUCCESS){

// 初始化成功

Log.e("error","haha");

}

else{

Log.e("error","呕");

Toast.makeText(MainActivity.this,"初始化失败",Toast.LENGTH_SHORT);

}

}

});

Log.e("activityState","Activity_onCreate");

}

publicvoidspeak(Viewview){

Stringcontent=main_edit_text.getText().toString();

Log.e("error",content);

if(content.isEmpty()){

mTextToSpeech.speak("空空",TextToSpeech.QUEUE_ADD,null);

}else{

mTextToSpeech.speak(content,TextToSpeech.QUEUE_ADD,null);

}

}

@Override

protectedvoidonStart(){

super.onStart();

Log.e("activityState","Activity_onStart");

}

@Override

protectedvoidonRestart(){

super.onRestart();

Log.e("activityState","Activity_onRestart");

}

@Override

protectedvoidonPause(){

super.onPause();

Log.e("activityState","Activity_onPause");

}

@Override

protectedvoidonResume(){

super.onResume();

Log.e("activityState","Activity_onResume");

}

@Override

protectedvoidonStop(){

super.onStop();

// 不管是否正在朗读 TTS 都被打断

mTextToSpeech.stop();

// 关闭, 释放资源

mTextToSpeech.shutdown();

}

@Override

protectedvoidonDestroy(){

if(mTextToSpeech!=null){

mTextToSpeech.stop();

mTextToSpeech.shutdown();

mTextToSpeech=null;

}

super.onDestroy();

}

}

activity_main.xml

注意设置 button 点击动作为 speak<?xml version="1.0"encoding="utf-8"?>

Android:layout_width="match_parent"

Android:layout_height="wrap_content"

Android:orientation="horizontal"

>

Android:id="@+id/message"

Android:layout_width="wrap_content"

Android:layout_height="match_parent"

Android:layout_weight="1"

Android:hint="Enter a message">

Android:id="@+id/button"

Android:layout_width="wrap_content"

Android:layout_height="wrap_content"

Android:onClick="speak"

Android:text="Read">

BUG 记录

如果出现 speak failed: not bound to TTS engine 并且是 Android 11

注意: 模拟器是 Android11 版本要在 AndroidManifest.xml 中加入
