1、语音播放直接用系统工具就好了，这个就不多说了，根据传入的路径（网络路径或本地路径均可）播放音频文件

/** * Created by zhb on 2017/1/16. * 音乐在线播放 */public class PlayManager {    private Context mcontext;    public PlayManager(Context context){        this.mcontext = context;    }    public void play(String song){        MediaPlayer mp = new MediaPlayer();        try {//          存储在SD卡或其他文件路径下的媒体文件//          例如：mp.setDataSource("/sdcard/test.mp3");//          网络上的媒体文件//          例如：mp.setDataSource("http://www...../music/test.mp3");            mp.setDataSource(song);            mp.prepare();            mp.start();        } catch (Exception e) {            e.printStackTrace();        }    }}

2.录制amr格式音频文件（微信语音便用的这种格式，至于音频文件格式之间的比较请自行百度）

/** * Created by zhb on 2017/1/16. * 本地录音 */public class RecordManager {    //录制成amr格式............................................................    private Context mcontext;    MediaRecorder mediaRecorder ;    public RecordManager(Context context){        this.mcontext = context;        //TODO 初始化安装路径，录音流程    }    /**开始录制*/    public void start_amr(){        mediaRecorder = new MediaRecorder();        /**         * mediaRecorder.setAudioSource设置声音来源。         * MediaRecorder.AudioSource这个内部类详细的介绍了声音来源。         * 该类中有许多音频来源，不过最主要使用的还是手机上的麦克风，MediaRecorder.AudioSource.MIC         */        mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);        /**         * mediaRecorder.setOutputFormat代表输出文件的格式。该语句必须在setAudioSource之后，在prepare之前。         * OutputFormat内部类，定义了音频输出的格式，主要包含MPEG_4、THREE_GPP、RAW_AMR……等。         */        mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);        /**         * mediaRecorder.setAddioEncoder()方法可以设置音频的编码         * AudioEncoder内部类详细定义了两种编码：AudioEncoder.DEFAULT、AudioEncoder.AMR_NB         */        mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);        /**         * 设置录音之后，保存音频文件的位置,一般是SD卡的位置         */        mediaRecorder.setOutputFile(String.valueOf(PathManger.getVoicePath()));        /**         * 调用start开始录音之前，一定要调用prepare方法。         */        try {            mediaRecorder.prepare();            mediaRecorder.start();        }        catch (IllegalStateException e) {            e.printStackTrace();        }        catch (IOException e) {            e.printStackTrace();        }    }    /**停止录音*/    public void stop_amr(){        mediaRecorder.stop();        mediaRecorder.release();        mediaRecorder = null;    }    /**重置录音*/    public void reset_amr(){        mediaRecorder.reset();    }}

3、录制MP3格式音频文件，配置转换工具包（这个比较简单，配置以下文件即可）

添加flame.jar，并在armeabi和armeabi-v7a文件夹添加libmp3lame.so

4、录制MP3格式音频文件（个人觉得这种格式能比较好的统一android端和iOS端的音频文件，虽然方法相对比较繁杂一些）

/** * Created by zhb on 2017/1/16. * 本地录音 */public class RecordManager {    //录制成MP3格式..............................................    /**构造时候需要的Activity，主要用于获取文件夹的路径*/    private Activity activity;    /**文件代号*/    public static final int RAW = 0X00000001;    public static final int MP3 = 0X00000002;    /**文件路径*/    private String rawPath = null;    private String mp3Path = null;    /**采样频率*/    private static final int SAMPLE_RATE = 11025;    /**录音需要的一些变量*/    private short[] mBuffer;    private AudioRecord mRecorder;    /**录音状态*/    private boolean isRecording = false;    /**是否转换ok*/    private boolean convertOk = false;    public RecordManager(Activity activity, String rawPath, String mp3Path) {        this.activity = activity;        this.rawPath = rawPath;        this.mp3Path = mp3Path;    }    /**开始录音*/    public boolean start_mp3() {        // 如果正在录音，则返回        if (isRecording) {            return isRecording;        }        // 初始化        if (mRecorder == null) {            initRecorder();        }        getFilePath();        mRecorder.startRecording();        startBufferedWrite(new File(rawPath));        isRecording = true;        return isRecording;    }    /**停止录音，并且转换文件,这很可能是个耗时操作，建议在后台中做*/    public boolean stop_mp3() {        if (!isRecording) {            return isRecording;        }        // 停止        mRecorder.stop();        isRecording = false;//TODO        // 开始转换（转换代码就这两句）        FLameUtils lameUtils = new FLameUtils(1, SAMPLE_RATE, 96);        convertOk = lameUtils.raw2mp3(rawPath, mp3Path);        return isRecording ^ convertOk;// convertOk==true,return true    }    /**获取文件的路径*/    public String getFilePath(int fileAlias) {        if (fileAlias == RAW) {            return rawPath;        } else if (fileAlias == MP3) {            return mp3Path;        } else            return null;    }    /**清理文件*/    public void cleanFile(int cleanFlag) {        File f = null;        try {            switch (cleanFlag) {                case MP3:                    f = new File(mp3Path);                    if (f.exists())                        f.delete();                    break;                case RAW:                    f = new File(rawPath);                    if (f.exists())                        f.delete();                    break;                case RAW | MP3:                    f = new File(rawPath);                    if (f.exists())                        f.delete();                    f = new File(mp3Path);                    if (f.exists())                        f.delete();                    break;            }            f = null;        } catch (Exception e) {            e.printStackTrace();        }    }    /**关闭,可以先调用cleanFile来清理文件*/    public void close() {        if (mRecorder != null)            mRecorder.release();        activity = null;    }    /**初始化*/    private void initRecorder() {        int bufferSize = AudioRecord.getMinBufferSize(SAMPLE_RATE,                AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT);        mBuffer = new short[bufferSize];        mRecorder = new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLE_RATE,                AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT,                bufferSize);    }    /**设置路径，第一个为raw文件，第二个为mp3文件*/    private void getFilePath() {        try {            String folder = "audio_recorder_2_mp3";            String fileName = String.valueOf(System.currentTimeMillis());            if (rawPath == null) {                File raw = new File(activity.getDir(folder,                        activity.MODE_PRIVATE), fileName + ".raw");                raw.createNewFile();                rawPath = raw.getAbsolutePath();                raw = null;            }            if (mp3Path == null) {                File mp3 = new File(activity.getDir(folder,                        activity.MODE_PRIVATE), fileName + ".mp3");                mp3.createNewFile();                mp3Path = mp3.getAbsolutePath();                mp3 = null;            }            Log.d("rawPath", rawPath);            Log.d("mp3Path", mp3Path);            runCommand("chmod 777 " + rawPath);            runCommand("chmod 777 " + mp3Path);        } catch (Exception e) {            e.printStackTrace();        }    }    /**执行cmd命令，并等待结果*/    private boolean runCommand(String command) {        boolean ret = false;

       } finally {            try {                process.destroy();            } catch (Exception e) {                e.printStackTrace();            }        }        return ret;    }    /**写入到raw文件*/    private void startBufferedWrite(final File file) {        new Thread(new Runnable() {            @Override            public void run() {                DataOutputStream output = null;                try {                    output = new DataOutputStream(new BufferedOutputStream(                            new FileOutputStream(file)));                    while (isRecording) {                        int readSize = mRecorder.read(mBuffer, 0,                                mBuffer.length);                        for (int i = 0; i < readSize; i++) {                            output.writeShort(mBuffer[i]);                        }                    }                } catch (IOException e) {                    e.printStackTrace();

                           }                        }                    }                }            }        }).start();    }}

5、最后在自己想调用的地方调用就好了，PathManger这个是我自己的路径管理工具，这里不贴了，反正自己直接放一个路径字符串进去就好了

/**初始化语音*/    private void initVoice() {        //录音        RecordManager = new RecordManager(                this,                String.valueOf(PathManger.getVoicePathToRaw()),                String.valueOf(PathManger.getVoicePathToMp3()));        bb.setOnTouchListener(new View.OnTouchListener() {            @Override            public boolean onTouch(View v, MotionEvent event) {                switch(event.getAction()){                    case MotionEvent.ACTION_DOWN:                        RecordManager.start_mp3();                        break;                    case MotionEvent.ACTION_MOVE:                        break;                    case MotionEvent.ACTION_UP:                        RecordManager.stop_mp3();                        break;                }                return false;            }        });        //语音播放        final PlayManager PlayManager = new PlayManager(this);        bb.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {            PlayManager.play(String.valueOf(PathManger.getVoicePathToMp3()));                                            }        });    }
