Android实现录音方法(仿微信语音、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

this(Environment.getExternalStorageDirectory()+"/record/");

}

public AudioRecoderUtils(String filePath) {

File path = new File(filePath);

if(!path.exists())

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 + TimeUtils.getCurrentTime() + ".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());

}

}

/**

* 停止录音

*/

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.reset();

mMediaRecorder.release();

mMediaRecorder = null;

audioStatusUpdateListener.onStop(filePath);

filePath = "";

}catch (RuntimeException e){

mMediaRecorder.reset();

mMediaRecorder.release();

mMediaRecorder = null;

File file = new File(filePath);

if (file.exists())

file.delete();

filePath = "";

}

return endTime - startTime;

}

/**

* 取消录音

*/

public void cancelRecord(){

try {

mMediaRecorder.stop();

mMediaRecorder.reset();

mMediaRecorder.release();

mMediaRecorder = null;

}catch (RuntimeException e){

mMediaRecorder.reset();

mMediaRecorder.release();

mMediaRecorder = null;

}

File file = new File(filePath);

if (file.exists())

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 = (double)mMediaRecorder.getMaxAmplitude() / BASE;

double db = 0;// 分贝

if (ratio > 1) {

db = 20 * Math.log10(ratio);

if(null != audioStatusUpdateListener) {

audioStatusUpdateListener.onUpdate(db,System.currentTimeMillis()-startTime);

}

}

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);

/**

* 停止录音

* @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

mImageView.getDrawable().setLevel((int) (3000 + 6000 * db / 100));

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 (event.getAction()){

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;

}

});
