Android仿微信语音消息的录制和播放功能

概述一、简述效果：实现功能：长按Button时改变Button显示文字，d出Dialog（动态更新音量），动态生成录音文件，开始录音；

一、简述

效果：

实现功能：

长按button时改变button显示文字，d出Dialog（动态更新音量），动态生成录音文件，开始录音；

监听手指动作，规定区域。录音状态下手指划出规定区域取消录音，删除生成的录音文件；

监听手指动作。当手指抬起时，判断是否开始录音，录音时长是否过短，符合条件则提示录音时长过短；正常结束时通过回调返回该次录音的文件路径和时长。

4.点击录音列表的item时，播放动画，播放对应的音频文件。

主要用到4个核心类：

自定义录音按钮（AudioRecordbutton）；

d框管理类（DialogManager）；

录音管理类（AudioManager）。

1.AudioRecordbutton状态：

1.STATE_norMAL:普通状态

2.STATE_RECORDING:录音中

3.STATE_CANCEL：取消录音

2.DialogManager状态:

1.RECORDING：录音中

2.WANT_TO_CANCEL：取消录音

3.TOO_SHORT：录音时间太短

3.AudioManager：

1.prepare():准备状态

2.cancel()：取消录音

3.release():正常结束录音

4.getVoiceLevel()：获取音量

核心逻辑：

自定义button，重写ontouchEvent()方法。

伪代码：

class AudioRecorderbutton{ ontouchEvent(){ DOWN:  changebuttonState(STATE_RECORDING);          | DialogManager.showDialog(RECORDING)  触发LongClick事件(AudioManager.prepare() --> end prepared --> |       );          | getVoiceLevel();//开启一个线程，更新Dialog上的音量等级  MOVE:  if(wantCancel(x,y)){  DialogManager.showDialog(WANT_TO_CANCEL);更新Dialog  changebuttonState(STATE_WANT_TO_CANCEL);更新button状态  }else{  DialogManager.showDialog(WANT_TO_CANCEL);  changebuttonState(STATE_RECORDING);  }  UP:  if(wantCancel == curState){//当前状态是想取消状态  AudioManager.cancel();  }  if(STATE_RECORDING = curState){  if(tooShort){//判断录制时长，如果录制时间过短   DialogManager.showDialog(TOO_SHORT);  }  AudioManager.release();  callbackActivity(url,time);//(当前录音文件路径，时长)  } }}

二、MediaManager封装

简述：使用MediaPlayer播放录制好的音频文件，要注意MediaPlayer资源的释放。

代码：

import androID.media.*;import java.io.IOException;/** * 播放管理类 */public class MediaManager { private static MediaPlayer mMediaPlayer; private static boolean isPause; public static voID playSound(String filePath,MediaPlayer.OnCompletionListener onCompletionListener) { 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 {  mMediaPlayer.setAudioStreamType(androID.media.AudioManager.STREAM_MUSIC);  mMediaPlayer.setonCompletionListener(onCompletionListener);  mMediaPlayer.setDataSource(filePath);  mMediaPlayer.prepare();  mMediaPlayer.start(); } catch (IOException e) {  e.printstacktrace(); } } public static voID pause(){ if(mMediaPlayer != null && mMediaPlayer.isPlaying()){  mMediaPlayer.pause();  isPause = true; } } public static voID resume(){ if(mMediaPlayer != null && isPause){  mMediaPlayer.start();  isPause = false; } } public static voID release(){ if(mMediaPlayer != null){  mMediaPlayer.release();  mMediaPlayer = null; } }}

三、DialogManager封装

封装了6个方法：

1. showRecordingDialog()：用来设置Diaog布局，拿到控件的引用，显示Dialog。

2. recording()：更改Dialog状态为录音中状态。

3. wantToCancel()：更改Dialog状态为想要取消状态。

4. tooShort()：更改Dialog状态为录音时长过短状态。

5. dismissDialog()：移除Dialog。

6. updateVoiceLevel()：用来更新音量图片。

代码：

import androID.app.Dialog;import androID.content.Context;import androID.vIEw.LayoutInflater;import androID.vIEw.VIEw;import androID.Widget.ImageVIEw;import androID.Widget.TextVIEw;import com.tIDdlerliu.wxrecorder.R;/** * Dialog管理类 */public class DialogManager { private Dialog mDialog; private ImageVIEw mIcon; private ImageVIEw mVoice; private TextVIEw mLabel; private Context mContext; public DialogManager(Context context) { mContext = context; } /** * 显示Dialog */ public voID showRecordingDialog(){ //将布局应用于Dialog mDialog = new Dialog(mContext,R.style.theme_AudioDialog); LayoutInflater inflater = LayoutInflater.from(mContext); VIEw vIEw = inflater.inflate(R.layout.dialog_recorder,null); mDialog.setContentVIEw(vIEw); //成员控件赋值 mIcon = (ImageVIEw) mDialog.findVIEwByID(R.ID.recorder_dialog_icon); mVoice = (ImageVIEw) mDialog.findVIEwByID(R.ID.recorder_dialog_voice); mLabel = (TextVIEw) mDialog.findVIEwByID(R.ID.recorder_dialog_label); mDialog.show(); } public voID recording(){ if(mDialog != null && mDialog.isShowing()){  mIcon.setVisibility(VIEw.VISIBLE);  mVoice.setVisibility(VIEw.VISIBLE);  mLabel.setVisibility(VIEw.VISIBLE);  mIcon.setimageResource(R.mipmap.recorder);  mLabel.setText("手指上滑，取消发送"); } } public voID wantToCancel(){ if(mDialog != null && mDialog.isShowing()){  mIcon.setVisibility(VIEw.VISIBLE);  mVoice.setVisibility(VIEw.GONE);  mLabel.setVisibility(VIEw.VISIBLE);  mIcon.setimageResource(R.mipmap.cancel);  mLabel.setText("松开手指，取消发送"); } } public voID tooShort(){ if(mDialog != null && mDialog.isShowing()){  mIcon.setVisibility(VIEw.VISIBLE);  mVoice.setVisibility(VIEw.GONE);  mLabel.setVisibility(VIEw.VISIBLE);  mIcon.setimageResource(R.mipmap.voice_to_short);  mLabel.setText("录音时间过短"); } } public voID dismissDialog(){ if(mDialog != null && mDialog.isShowing()){  mDialog.dismiss();  mDialog = null; } } /** * 通过level更新音量资源图片 * @param level */ public voID updateVoiceLevel(int level){ if(mDialog != null && mDialog.isShowing()){  int resID = mContext.getResources().getIDentifIEr("v"+level,"mipmap",mContext.getPackagename());  mVoice.setimageResource(resID); } }}

四、AudioManager封装

4.1 添加必要权限

<uses-permission androID:name="androID.permission.RECORD_AUdio"/><uses-permission androID:name="androID.permission.WRITE_EXTERNAL_STORAGE"/>

4.2 代码

import androID.media.MediaRecorder;import java.io.file;import java.io.IOException;import java.util.UUID;/** * 录音管理类 */public class AudioManager { private String mDir;//文件夹名称 private MediaRecorder mMediaRecorder; private String mCurrentfilePath;//文件储存路径 private static AudioManager mInstance; //表明MediaRecorder是否进入prepare状态（状态为true才能调用stop和release方法） private boolean isPrepared; public AudioManager(String dir) { mDir = dir; } public String getCurrentfilePath() { return mCurrentfilePath; } /** * 准备完毕接口 */ public interface AudioStateListener{ voID wellPrepared(); } public AudioStateListener mListener; public voID setonAudioStateListener(AudioStateListener Listener){ mListener = Listener; } /** * 单例 * @return AudioManager */ public static AudioManager getInstance(String dir){ if (mInstance == null){  synchronized (AudioManager.class){  if(mInstance == null){   mInstance = new AudioManager(dir);  }  } } return mInstance; } /** * 准备 */ public voID prepareAudio() { try {  isPrepared = false;  file dir = new file(mDir);//创建文件夹  if (!dir.exists()) {  dir.mkdirs();  }  String filename = generatefilename();//随机生成文件名  file file = new file(dir,filename);//创建文件  mCurrentfilePath = file.getabsolutePath();  mMediaRecorder = new MediaRecorder();  mMediaRecorder.setoutputfile(file.getabsolutePath());//设置输出文件  mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);//设置麦克风为音频源  mMediaRecorder.setoutputFormat(MediaRecorder.OutputFormat.AMR_NB);//设置音频格式  mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);//设置音频编码  mMediaRecorder.prepare();  mMediaRecorder.start();  //准备结束  isPrepared = true;  if (mListener != null){  mListener.wellPrepared();  } } catch (IOException e) {  e.printstacktrace(); } } /** * 随机生成文件的名称 * @return */ private String generatefilename() { return UUID.randomUUID().toString()+".amr"; } /** * 获取音量等级 */ public int getVoiceLevel(int maxLevel) { if (isPrepared) {  try {  //mMediaRecorder.getMaxAmplitude() 范围:1-32767  return maxLevel * mMediaRecorder.getMaxAmplitude() / 32768 + 1;//最大值 * [0,1）+ 1  } catch (Exception e) {  } } return 1; } /** * 重置 */ public voID release(){ if(mMediaRecorder != null){  mMediaRecorder.stop();  mMediaRecorder.release();  mMediaRecorder = null; } } /** * 取消 */ public voID cancel(){ release(); //删除产生的文件 if(mCurrentfilePath != null){  file file = new file(mCurrentfilePath);  file.delete();  mCurrentfilePath = null; } }}

五、AudioRecordbutton封装

import androID.annotation.Suppresslint;import androID.content.Context;import androID.os.Environment;import androID.os.Handler;import androID.os.Message;import androID.util.AttributeSet;import androID.vIEw.MotionEvent;import androID.vIEw.VIEw;import androID.Widget.button;import com.tIDdlerliu.wxrecorder.R;/** * 自定义button */@Suppresslint("AppCompatCustomVIEw")public class AudioRecordbutton extends button implements AudioManager.AudioStateListener{ private static final int STATE_norMAL = 1;//默认状态 private static final int STATE_RECORDING = 2;//录音状态 private static final int STATE_WANT_CANCEL = 3;//想取消状态 private static final int disTANCE_Y_CANCEL = 50;//定义上滑取消距离 private int mCurState = STATE_norMAL;//记录当前状态 private boolean isRecording = false;//是否在录音状态 private DialogManager mDialogManager; private AudioManager mAudioManager; private float mTime;//记录录音时长 private boolean mReady;//是否触发OnLongClick事件 private boolean isComplete = true;//是否已经完成 public AudioRecordbutton(Context context) { this(context,null); } public AudioRecordbutton(Context context,AttributeSet attrs) { super(context,attrs); mDialogManager = new DialogManager(getContext()); String dir = Environment.getExternalStorageDirectory()+"/TIDdlerliu/recorder/audios";//最好判断SD卡是否存在可读 mAudioManager = AudioManager.getInstance(dir); mAudioManager.setonAudioStateListener(this); setonLongClickListener(new OnLongClickListener() {  @OverrIDe  public boolean onLongClick(VIEw v) {  mReady = true;  mAudioManager.prepareAudio();  return false;  } }); } /** * 录音完成后的回调 */ public interface AudioFinishRecorderListener { voID onFinish(float seconds,String filePath); } private AudioFinishRecorderListener mAudioFinishRecorderListener; public voID setAudioFinishRecorderListener(AudioFinishRecorderListener Listener){ mAudioFinishRecorderListener = Listener; } private static final int MSG_AUdio_PREPARED = 0x110; private static final int MSG_VOICE_CHANGED = 0x111; private static final int MSG_DIALOG_disMISS = 0x112; private static final int MSG_AUdio_COMPLETE = 0x113;//达到最大时长，自动完成 /** * 获取音量大小 */ private Runnable mGetVoiceLevelRunnable = new Runnable() { @OverrIDe public voID run() {  while (isRecording){  try {   Thread.sleep(100);   mTime += 0.1f;   if(mTime >= 60f){//60s自动触发完成录制   mHandler.sendEmptyMessage(MSG_AUdio_COMPLETE);   }   mHandler.sendEmptyMessage(MSG_VOICE_CHANGED);  } catch (InterruptedException e) {   e.printstacktrace();  }  } } }; private Handler mHandler = new Handler(){ @OverrIDe public voID handleMessage(Message msg) {  switch (msg.what){  case MSG_AUdio_PREPARED:   //显示应该在audio end prepared以后   mDialogManager.showRecordingDialog();   isRecording = true;   isComplete = false;   new Thread(mGetVoiceLevelRunnable).start();   break;  case MSG_VOICE_CHANGED:   mDialogManager.updateVoiceLevel(mAudioManager.getVoiceLevel(7));   break;  case MSG_DIALOG_disMISS:   mDialogManager.dismissDialog();   break;  case MSG_AUdio_COMPLETE:   complete();   reset();   break;  default:   break;  } } }; @OverrIDe public voID wellPrepared() { mHandler.sendEmptyMessage(MSG_AUdio_PREPARED); } @OverrIDe public boolean ontouchEvent(MotionEvent event) { int action = event.getAction(); int x = (int) event.getX(); int y = (int) event.getY(); switch (action){  case MotionEvent.ACTION_DOWN:  changeState(STATE_RECORDING);  break;  case MotionEvent.ACTION_MOVE:  if(isRecording){   //根据(x,y)坐标，判断是否想要取消   if (wantToCancel(x,y)){   changeState(STATE_WANT_CANCEL);   }else{   changeState(STATE_RECORDING);   }  }  break;  case MotionEvent.ACTION_UP:  if(!isComplete){//没有执行超时自动完成逻辑   if (!mReady) {//还未触发OnLongClick事件   reset();   return super.ontouchEvent(event);   }   if (!isRecording || mTime < 0.6f) {//还未开始录音 或者 录制时长过短   mDialogManager.tooShort();   mAudioManager.cancel();   mHandler.sendEmptyMessageDelayed(MSG_DIALOG_disMISS,1300);//1.3秒后关闭对话框   } else if (mCurState == STATE_RECORDING) {//正常录制结束   complete();   } else if (mCurState == STATE_WANT_CANCEL) {//想要取消状态   mDialogManager.dismissDialog();   mAudioManager.cancel();   }   reset();  }  break; } return super.ontouchEvent(event); } /** * 正常录制结束 */ private voID complete() { mDialogManager.dismissDialog(); mAudioManager.release(); if(mAudioFinishRecorderListener != null && !isComplete){  mAudioFinishRecorderListener.onFinish(mTime,mAudioManager.getCurrentfilePath()); } } /** * 恢复状态和标志位 */ private voID reset() { isRecording = false; mReady = false; mTime = 0; isComplete = true; changeState(STATE_norMAL); } /** * 根据(x,y)坐标，判断是否想要取消 * @param x * @param y * @return */ private boolean wantToCancel(int x,int y) { if(x < 0 || x > getWIDth()){//手指移出button范围  return true; } if(y < - disTANCE_Y_CANCEL || y > getHeight() + disTANCE_Y_CANCEL){//手指移出Y轴设定范围  return true; } return false; } /** * 改变状态 * @param state */ private voID changeState(int state) { if(mCurState != state){  mCurState = state;  switch (state){  case STATE_norMAL:   setBackgroundResource(R.drawable.btn_recorder_normal);   setText(R.string.str_recorder_normal);   break;  case STATE_RECORDING:   setBackgroundResource(R.drawable.btn_recorder_recording);

  mDialogManager.wantToCancel();   break;  default:   break;  } } }}
