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;
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;
public void startRecord() {
// 开始录音
if (mMediaRecorder == null)
mMediaRecorder = new MediaRecorder();
try {
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);// 设置麦克风
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
filePath = FolderPath + TimeUtils.getCurrentTime() + ".amr" ;
mMediaRecorder.setOutputFile(filePath);
mMediaRecorder.setMaxDuration(MAX_LENGTH);
mMediaRecorder.prepare();
mMediaRecorder.start();
// AudioRecord audioRecord.
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());
}
}
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;
}
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;
}
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 {
public void onUpdate(double db,long time);
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）
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;
}
});
总结
