Android实现录⾳⽅法（仿语⾳、麦克风录⾳、发送语
⾳、解决5.0以上BUG）
先给⼤家展⽰下效果图，如果⼤家感觉不错，请参考使⽤⽅法，
效果图如下所⽰：
使⽤⽅法：
录⾳⼯具类：AudioRecoderUtils.java，代码如下：
public class AudioRecoderUtils {
//⽂件路径
private String filePath;
//⽂件夹路径
private String FolderPath;
private MediaRecorder mMediaRecorder;
private final String TAG = "fan";
public static final int MAX_LENGTH = 1000 * 60 * 10;// 最⼤录⾳时长1000*60*10;
private OnAudioStatusUpdateListener audioStatusUpdateListener;
/**
* ⽂件存储默认sdcard/record
*/
public AudioRecoderUtils(){
//默认保存路径为/sdcard/record/下
ExternalStorageDirectory()+"/record/");
}
public AudioRecoderUtils(String filePath) {
File path = new File(filePath);
if(!ists())
path.mkdirs();
this.FolderPath = filePath;
}
private long startTime;
private long endTime;
/**
* 开始录⾳使⽤amr格式
*  录⾳⽂件
* @return
*/
public void startRecord() {
// 开始录⾳
/* ①Initial：实例化MediaRecorder对象 */
if (mMediaRecorder == null)
mMediaRecorder = new MediaRecorder();
try {
/* ②setAudioSource/setVedioSource */
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);// 设置麦克风
/* ②设置⾳频⽂件的编码：AAC/AMR_NB/AMR_MB/Default 声⾳的（波形）的采样 */
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
/*
* ②设置输出⽂件的格式：THREE_GPP/MPEG-4/RAW_AMR/Default THREE_GPP(3gp格式
* ，H263视频/ARM⾳频编码)、MPEG-4、RAW_AMR(只⽀持⾳频且⾳频编码要求为AMR_NB)
*/
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
filePath = FolderPath + CurrentTime() + ".amr" ;
/* ③准备 */
mMediaRecorder.setOutputFile(filePath);
mMediaRecorder.setMaxDuration(MAX_LENGTH);
mMediaRecorder.prepare();
/
* ④开始 */
mMediaRecorder.start();
// AudioRecord audioRecord.
/* 获取开始时间* */
startTime = System.currentTimeMillis();
updateMicStatus();
Log.e("fan", "startTime" + startTime);
} catch (IllegalStateException e) {
Log.i(TAG, "call startAmr(File mRecAudioFile) failed!" + e.getMessage());
} catch (IOException e) {
Log.i(TAG, "call startAmr(File mRecAudioFile) failed!" + e.getMessage());
mkdirs方法}
}
*/
public long stopRecord() {
if (mMediaRecorder == null)
return 0L;
endTime = System.currentTimeMillis();
//有⼀些⽹友反应在5.0以上在调⽤stop的时候会报错，翻阅了⼀下⾕歌⽂档发现上⾯确实写的有可能会报错的情况，捕获异常清理⼀下就⾏了，感谢⼤家反馈！  try {
mMediaRecorder.stop();
mMediaRecorder = null;
filePath = "";
}catch (RuntimeException e){
mMediaRecorder = null;
File file = new File(filePath);
if (ists())
file.delete();
filePath = "";
}
return endTime - startTime;
}
/**
* 取消录⾳
*/
public void cancelRecord(){
try {
mMediaRecorder.stop();
mMediaRecorder = null;
}catch (RuntimeException e){
mMediaRecorder = null;
}
File file = new File(filePath);
if (ists())
file.delete();
filePath = "";
}
private final Handler mHandler = new Handler();
private Runnable mUpdateMicStatusTimer = new Runnable() {
public void run() {
updateMicStatus();
}
};
private int BASE = 1;
private int SPACE = 100;// 间隔取样时间
public void setOnAudioStatusUpdateListener(OnAudioStatusUpdateListener audioStatusUpdateListener) {
this.audioStatusUpdateListener = audioStatusUpdateListener;
}
/**
* 更新麦克状态
*/
private void updateMicStatus() {
if (mMediaRecorder != null) {
double ratio = (MaxAmplitude() / BASE;
double db = 0;// 分贝
if (ratio > 1) {
db = 20 * Math.log10(ratio);
if(null != audioStatusUpdateListener) {
}
}
mHandler.postDelayed(mUpdateMicStatusTimer, SPACE);
}
}
public interface OnAudioStatusUpdateListener {
/**
* 录⾳中...
* @param db 当前声⾳分贝
* @param time 录⾳时长
*/
public void onUpdate(double db,long time);
* @param filePath 保存路径
*/
public void onStop(String filePath);
}
}
使⽤很简单，主要就是开始录⾳startRecord()、取消录⾳cancelRecord()、结束录⾳stopRecord()和录⾳监听setOnAudioStatusUpdateListener()，注意，取消录⾳不保存⽂件，结束录⾳会保存⽂件！
在布局⽂件中添加⼀个控件（任意⼀个都⾏）
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="按住说话"
android:textColor="@android:color/white"
android:id="@+id/button"
android:background="@color/colorPrimary"
/>
在Activity中使⽤：
//当前布局⽂件的根layout
final RelativeLayout rl = (RelativeLayout) findViewById(R.id.rl);
mButton = (Button) findViewById(R.id.button);
//PopupWindow的布局⽂件
final View view = View.inflate(this, R.layout.layout_microphone, null);
final PopupWindowFactory mPop = new PopupWindowFactory(this,view);
//PopupWindow布局⽂件⾥⾯的控件
mImageView = (ImageView) view.findViewById(R.id.iv_recording_icon);
mTextView = (TextView) view.findViewById(R.id.tv_recording_time);
mAudioRecoderUtils = new AudioRecoderUtils();
//录⾳回调
mAudioRecoderUtils.setOnAudioStatusUpdateListener(new AudioRecoderUtils.OnAudioStatusUpdateListener() {
//录⾳中....db为声⾳分贝，time为录⾳时长
@Override
public void onUpdate(double db, long time) {
//根据分贝值来设置录⾳时话筒图标的上下波动，下⾯有讲解
mTextView.setText(TimeUtils.long2String(time));
}
//录⾳结束，filePath为保存路径
@Override
public void onStop(String filePath) {
Toast.makeText(MainActivity.this, "录⾳保存在：" + filePath, Toast.LENGTH_SHORT).show();
mTextView.setText(TimeUtils.long2String(0));
}
});
//Button的touch监听
mButton.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (Action()){
case MotionEvent.ACTION_DOWN:
mPop.showAtLocation(rl,Gravity.CENTER,0,0);
mButton.setText("松开保存");
mAudioRecoderUtils.startRecord();
break;
case MotionEvent.ACTION_UP:
mAudioRecoderUtils.stopRecord();  //结束录⾳（保存录⾳⽂件）
/
/      mAudioRecoderUtils.cancelRecord(); //取消录⾳（不保存录⾳⽂件）
mPop.dismiss();
mButton.setText("按住说话");
break;
}
return true;
}
});
