一、简述

效果：

实现功能：

长按Button时改变Button显示文字，弹出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)；

弹框管理类(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

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;

}

}

}
