android本身具有文字转语音播放的TTS,一些第三方的sdk，像百度语音，科大讯飞语音等等都提供了文字转语音播放的功能，但这些第三方sdk大都收费，还挺贵的。

下面介绍一下两种播放的代码。

第一种播放方式 TTS

public class MyTTS extends UtteranceProgressListener {    private  TextToSpeech tts;    private boolean isSupportCN = true;    private static MyTTS instance;    public static MyTTS getInstance(Context context){        if(instance == null){            synchronized(MyTTS.class){                instance = new MyTTS(context.getApplicationContext());            }        }        return instance;    }    private MyTTS(final Context context){        tts =  new TextToSpeech(context , new TextToSpeech.OnInitListener() {            @Override            public void onInit(int status) {                if(status==TextToSpeech.SUCCESS){                    int result = tts.setLanguage(Locale.CHINA);                    tts.setPitch(1.0f);                    tts.setSpeechRate(1.0f);                    tts.setOnUtteranceProgressListener(MyTTS.this);                    if(result == TextToSpeech.LANG_NOT_SUPPORTED || result ==TextToSpeech.LANG_MISSING_DATA){                        isSupportCN = false;                        Toast.makeText(context,"抱歉，不支持中文播放",Toast.LENGTH_SHORT).show();                    }                }            }        });    }    @Override    public void onStart(String utteranceId) {        Log.d("xulc","onStart---utteranceId--->"+utteranceId);    }    @Override    public void onDone(String utteranceId) {        Log.d("xulc","onDone---utteranceId--->"+utteranceId);    }    @Override    public void onError(String utteranceId) {        Log.d("xulc","onError---utteranceId--->"+utteranceId);    }    public TextToSpeech getTts() {        return tts;    }    public boolean isSupportCN() {        return isSupportCN;    }}

第二种 Mediaplayer播放的方法

public class VoicePlayer {    private ConcurrentLinkedQueue
   
     voiceUnitList;    private int index = 0;   //播放的下标位置    private MediaPlayer mediaPlayer;    private Context mcontext;    private boolean isPlaying = false;    private static VoicePlayer instance;    public static VoicePlayer getInstance(Context context){        if(instance==null){            synchronized (VoicePlayer.class){                instance = new VoicePlayer(context.getApplicationContext());            }        }        return instance;    }    private VoicePlayer(Context context){        voiceUnitList = new ConcurrentLinkedQueue<>();        mcontext = context;    }    public void addVoiceUnit(VoiceUnit unit){        voiceUnitList.add(unit);    }    public void play(){   //调动播放        if(isPlaying){  //正在播放        }else{            isPlaying = true;            playVoice();        }    }    private void playVoice(){        if(mediaPlayer==null){            mediaPlayer = new MediaPlayer();        }        VoiceUnit voiceUnit = voiceUnitList.peek();        if(voiceUnit!=null) {     //内容不为空，播放当前信息            if (index < voiceUnit.getVoices().length) {   //当前信息未播放完成。播放下一条                final Uri uri = Uri.parse("android.resource://"+mcontext.getApplicationContext().getPackageName()+"/" +voiceUnitList.peek().getVoices()[index]);                try {                    mediaPlayer.setDataSource(mcontext, uri);                    mediaPlayer.prepare();                    mediaPlayer.start();                    mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {                        @Override                        public void onCompletion(MediaPlayer mp) {                            Log.d("xulc", "播放了一个音频(index = ):"+index+"   "+uri.getPath());                            mediaPlayer.reset();                            index++;                            playVoice();                        }                    });                } catch (IOException e) {                    e.printStackTrace();                }            }else{  //播放下一项                Log.d("xulvcheng","播放下一项....");                handler.postDelayed(new Runnable() {                    @Override                    public void run() {                        voiceUnitList.poll();                        index = 0;                        playVoice();                    }                },2000);       //确定是否会造成  内存泄漏                //200ms 读取下一条            }        }else{            isPlaying = false;  //播放完成            index = 0;            Log.d("xulvcheng","播放完成的状态....");        }    }    private Handler handler = new MyHnadler();    private static class MyHnadler extends Handler {}    public void destory(){        if (mediaPlayer != null) {            mediaPlayer.stop();            mediaPlayer.release();            mediaPlayer = null;        }        if(handler!=null){            handler.removeCallbacksAndMessages(null);        }    }}
