本文实例为大家分享了Android实现语音播放与录音的具体代码，供大家参考，具体内容如下

项目用到的技术点和亮点

语音录音 (单个和列表)

语音播放(单个和列表)

语音录音封装

语音播放器封装

语音列表顺序播放

语音列表单个播放 复用问题处理

因为安装原生录音不能录mp3格式文件 而mp3格式是安卓和ios公用的，所以我们需要的是能直接录取mp3文件或者录完的格式转成mp3格式

下面添加这个库 能直接录mp3文件，我觉得是最方便的

compile ‘com.czt.mp3recorder:library:1.0.3'

1. 语音录音封装

代码简单 自己看吧

package com.video.zlc.audioplayer;

import com.czt.mp3recorder.MP3Recorder;

import com.video.zlc.audioplayer.utils.LogUtil;

import java.io.File;

import java.io.IOException;

import java.util.UUID;

/**

* @author zlc

*/

public class AudioManage {

private MP3Recorder mRecorder;

private String mDir; // 文件夹的名称

private String mCurrentFilePath;

private static AudioManage mInstance;

private boolean isPrepared; // 标识MediaRecorder准备完毕

private AudioManage(String dir) {

mDir = dir;

LogUtil.e("AudioManage=",mDir);

}

/**

* 回调“准备完毕”

* @author zlc

*/

public interface AudioStateListenter {

void wellPrepared(); // prepared完毕

}

public AudioStateListenter mListenter;

public void setOnAudioStateListenter(AudioStateListenter audioStateListenter) {

mListenter = audioStateListenter;

}

/**

* 使用单例实现 AudioManage

* @param dir

* @return

*/

public static AudioManage getInstance(String dir) {

if (mInstance == null) {

synchronized (AudioManage.class) { // 同步

if (mInstance == null) {

mInstance = new AudioManage(dir);

}

}

}

return mInstance;

}

/**

* 准备录音

*/

public void prepareAudio() {

try {

isPrepared = false;

File dir = new File(mDir);

if (!dir.exists()) {

dir.mkdirs();

}

String fileName = GenerateFileName(); // 文件名字

File file = new File(dir, fileName); // 路径+文件名字

//MediaRecorder可以实现录音和录像。需要严格遵守API说明中的函数调用先后顺序.

mRecorder = new MP3Recorder(file);

mCurrentFilePath = file.getAbsolutePath();

// mMediaRecorder = new MediaRecorder();

// mCurrentFilePath = file.getAbsolutePath();

// mMediaRecorder.setOutputFile(file.getAbsolutePath()); // 设置输出文件

// mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); // 设置MediaRecorder的音频源为麦克风

// mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB); // 设置音频的格式

// mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); // 设置音频的编码为AMR_NB

// mMediaRecorder.prepare();

// mMediaRecorder.start();

mRecorder.start(); //开始录音

isPrepared = true; // 准备结束

if (mListenter != null) {

mListenter.wellPrepared();

}

} catch (Exception e) {

e.printStackTrace();

LogUtil.e("prepareAudio",e.getMessage());

}

}

/**

* 随机生成文件名称

* @return

*/

private String GenerateFileName() {

// TODO Auto-generated method stub

return UUID.randomUUID().toString() + ".mp3"; // 音频文件格式

}

/**

* 获得音量等级——通过mMediaRecorder获得振幅，然后换算成声音Level

* maxLevel最大为7；

* @return

*/

public int getVoiceLevel(int maxLevel) {

if (isPrepared) {

try {

mRecorder.getMaxVolume();

return maxLevel * mRecorder.getMaxVolume() / 32768 + 1;

} catch (Exception e) {

e.printStackTrace();

}

}

return 1;

}

/**

* 释放资源

*/

public void release() {

if(mRecorder != null) {

mRecorder.stop();

mRecorder = null;

}

}

/**

* 停止录音

*/

public void stop(){

if(mRecorder!=null && mRecorder.isRecording()){

mRecorder.stop();

}

}

/**

* 取消(释放资源+删除文件)

*/

public void delete() {

release();

if (mCurrentFilePath != null) {

File file = new File(mCurrentFilePath);

file.delete(); //删除录音文件

mCurrentFilePath = null;

}

}

public String getCurrentFilePath() {

return mCurrentFilePath;

}

public int getMaxVolume(){

return mRecorder.getMaxVolume();

}

public int getVolume(){

return mRecorder.getVolume();

}

}

2. 语音播放器封装

package com.video.zlc.audioplayer.utils;

import android.content.Context;

import android.media.AudioManager;

import android.media.MediaPlayer;

import android.net.Uri;

/**

*

* @author zlc

*

*/

public class MediaManager {

private static MediaPlayer mMediaPlayer; //播放录音文件

private static boolean isPause = false;

static {

if(mMediaPlayer==null){

mMediaPlayer=new MediaPlayer();

mMediaPlayer.setOnErrorListener( new MediaPlayer.OnErrorListener() {

@Override

public boolean onError(MediaPlayer mp, int what, int extra) {

mMediaPlayer.reset();

return false;

}

});

}

}

/**

* 播放音频

* @param filePath

* @param onCompletionListenter

*/

public static void playSound(Context context,String filePath, MediaPlayer.OnCompletionListener onCompletionListenter){

if(mMediaPlayer==null){

mMediaPlayer = new MediaPlayer();

mMediaPlayer.setOnErrorListener( new MediaPlayer.OnErrorListener() {

@Override

public boolean onError(MediaPlayer mp, int what, int extra) {

mMediaPlayer.reset();

return false;

}

});

}else{

mMediaPlayer.reset();

}

try {

//详见“MediaPlayer”调用过程图

mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

mMediaPlayer.setOnCompletionListener(onCompletionListenter);

mMediaPlayer.setDataSource(filePath);

mMediaPlayer.prepare();

mMediaPlayer.start();

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

LogUtil.e("语音error==",e.getMessage());

}

}

/**

* 暂停

*/

public synchronized static void pause(){

if(mMediaPlayer!=null && mMediaPlayer.isPlaying()){

mMediaPlayer.pause();

isPause=true;

}

}

//停止

public synchronized static void stop(){

if(mMediaPlayer!=null && mMediaPlayer.isPlaying()){

mMediaPlayer.stop();

isPause=false;

}

}

/**

* resume继续

*/

public synchronized static void resume(){

if(mMediaPlayer!=null && isPause){

mMediaPlayer.start();

isPause=false;

}

}

public static boolean isPause(){

return isPause;

}

public static void setPause(boolean isPause) {

MediaManager.isPause = isPause;

}

/**

* release释放资源

*/

public static void release(){

if(mMediaPlayer!=null){

isPause = false;

mMediaPlayer.stop();

mMediaPlayer.release();

mMediaPlayer = null;

}

}

public synchronized static void reset(){

if(mMediaPlayer!=null) {

mMediaPlayer.reset();

isPause = false;

}

}

/**

* 判断是否在播放视频

* @return

*/

public synchronized static boolean isPlaying(){

return mMediaPlayer != null && mMediaPlayer.isPlaying();

}

}

3. 语音列表顺序播放

private int lastPos = -1;

//播放语音

private void playVoice(final int position, String from) {

LogUtil.e("playVoice position",position+"");

if(position >= records.size()) {

LogUtil.e("playVoice","全部播放完了");

stopAnimation();

MediaManager.reset();

return;

}

String voicePath = records.get(position).getPath();

LogUtil.e("playVoice",voicePath);

if(TextUtils.isEmpty(voicePath) || !voicePath.contains(".mp3")){

Toast.makeText(this,"语音文件不合法",Toast.LENGTH_LONG).show();

return;

}

if(lastPos != position && "itemClick".equals(from)){

stopAnimation();

MediaManager.reset();

}

lastPos = position;

//获取listview某一个条目的图片控件

int pos = position - id_list_voice.getFirstVisiblePosition();

View view = id_list_voice.getChildAt(pos);

id_iv_voice = (ImageView) view.findViewById(R.id.id_iv_voice);

LogUtil.e("playVoice position",pos+"");

if(MediaManager.isPlaying()){

MediaManager.pause();

stopAnimation();

}else if(MediaManager.isPause()){

startAnimation();

MediaManager.resume();

}else{

startAnimation();

MediaManager.playSound(this,voicePath, new MediaPlayer.OnCompletionListener() {

@Override

public void onCompletion(MediaPlayer mediaPlayer) {

//播放完停止动画 重置MediaManager

stopAnimation();

MediaManager.reset();

playVoice(position + 1, "loop");

}

});

}

}

4. 语音列表单个播放 复用问题处理

播放逻辑基本同上

private int lastPosition = -1;

private void playVoice(FendaListInfo.ObjsEntity obj, int position) {

String videoPath = obj.path;

if(TextUtils.isEmpty(videoPath) || !videoPath.contains(".mp3")){

Toast.makeText(this,"语音文件不合法",Toast.LENGTH_LONG).show();

return;

}

if(position != lastPosition){ //点击不同条目先停止动画 重置音频资源

stopAnimation();

MediaManager.reset();

}

if(mAdapter!=null)

mAdapter.selectItem(position, lastPosition);

lastPosition = position;

id_iv_voice.setBackgroundResource(R.drawable.animation_voice);

animationDrawable = (AnimationDrawable) id_iv_voice.getBackground();

if(MediaManager.isPlaying()){

stopAnimation();

MediaManager.pause();

}else if(MediaManager.isPause()){

startAnimation();

MediaManager.resume();

}else{

startAnimation();

MediaManager.playSound(this,videoPath, new MediaPlayer.OnCompletionListener() {

@Override

public void onCompletion(MediaPlayer mp) {

LogUtil.e("onCompletion","播放完成");

stopAnimation();

MediaManager.stop();

}

});

}

}

//核心方法

//点击了某一个条目 这个条目isSelect=true 上一个条目isSelect需要改为false 防止滑动过程中 帧动画复用问题

public void selectItem(int position, int lastPosition) {

LogUtil.e("selectItem"," ;lastPosition="+lastPosition+" ;position="+position);

if(lastPosition >= 0 && lastPosition < mDatas.size() && lastPosition != position){

FendaListInfo.ObjsEntity bean = mDatas.get(lastPosition);

bean.isSelect = false;

mDatas.set(lastPosition, bean);

notifyDataSetChanged();

}

if(position < mDatas.size() && position != lastPosition){

FendaListInfo.ObjsEntity bean = mDatas.get(position);

bean.isSelect = true;

mDatas.set(position,bean);

}

}

/**

* 适配器图片播放的动画处理

*/

private void setVoiceAnimation(ImageView iv_voice, FendaListInfo.ObjsEntity obj) {

//处理动画复用问题

AnimationDrawable animationDrawable;

if(obj.isSelect){

iv_voice.setBackgroundResource(R.drawable.animation_voice);

animationDrawable = (AnimationDrawable) iv_voice.getBackground();

if(MediaManager.isPlaying() && animationDrawable!=null){

animationDrawable.start();

}else{

iv_voice.setBackgroundResource(R.drawable.voice_listen);

animationDrawable.stop();

}

}else{

iv_voice.setBackgroundResource(R.drawable.voice_listen);

}

}
