This article will explain in detail how to use Android to imitate Wechat to record voice. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The details are as follows

Preface

I divided the recording into two parts.

1.UI interface, pop-up window read seconds 2. A class (including start, stop, create file name functions)

The first part

Due to the 6.0 permission problem, click the button to apply for permission to pass the pop-up window, how to apply for permission

Pop-up window layout popw_record.xml

Bounce

/ * start recording * / private void showPopup () {final View contentView = LayoutInflater.from (Orderdeatil.this) .propagate (R.layout.popw_record, null); mPopWindow = new PopupWindow (contentView, ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.WRAP_CONTENT, true); mPopWindow.setContentView (contentView); TextView startRe = (TextView) contentView.findViewById (R.id.startRecord) StartRe.setOnTouchListener (new View.OnTouchListener () {@ Override public boolean onTouch (View v, MotionEvent event) {switch (event.getAction ()) {case MotionEvent.ACTION_UP:// loosens the area where the code is executed after the event if (mPopWindow! = null) {mPopWindow.dismiss (); sr.stopRecording ();} break; case MotionEvent.ACTION_DOWN:// holds down the area where the code is executed after the event Chronometer timer = (Chronometer) contentView.findViewById (R.id.timer) Timer.setBase (SystemClock.elapsedRealtime ()); / / timer zeroing timer.start (); / / prompt to start recording sr.startRecording (); break; case MotionEvent.ACTION_CANCEL: if (mPopWindow! = null) {mPopWindow.dismiss (); sr.stopRecording (); / / stop recording} break; default: break;} return true;}}); ImageView close = (ImageView) contentView.findViewById (R.id.close) Close.setOnClickListener (new View.OnClickListener () {@ Override public void onClick (View v) {mPopWindow.dismiss ();}}); mPopWindow.setTouchable (true); mPopWindow.setFocusable (true); mPopWindow.setBackgroundDrawable (new BitmapDrawable ()); mPopWindow.setOutsideTouchable (true); mPopWindow.setTouchInterceptor (new View.OnTouchListener () {public boolean onTouch (View v, MotionEvent event) {if (event.getAction () = = MotionEvent.ACTION_OUTSIDE) {mPopWindow.dismiss (); return true;} return false;}) View rootview = LayoutInflater.from (Orderdeatil.this). Evaluate (R.layout.activity_orderdeatil, null); mPopWindow.showAtLocation (rootview, Gravity.CENTER, 0,0);}

Part II tool class

Class SoundRecorder {public void startRecording () {mRecorder = new MediaRecorder (); mRecorder.setAudioSource (MediaRecorder.AudioSource.MIC); mRecorder.setOutputFormat (MediaRecorder.OutputFormat.DEFAULT); mRecorder.setAudioEncoder (MediaRecorder.AudioEncoder.DEFAULT); mRecorder.setOutputFile (newFileName ()); try {/ / ready to start recording mRecorder.prepare (); mRecorder.start ();} catch (IllegalStateException e) {/ / TODO Auto-generated catch block e.printStackTrace ();} catch (IOException e) {/ / TODO Auto-generated catch block e.printStackTrace () }} public void stopRecording () {if (mRecorder! = null) {/ / added by ouyang start try {/ / the following three parameters must be added, otherwise it will fail in mediarecorder.stop (); / / error: RuntimeException:stop failed mRecorder.setOnErrorListener (null); mRecorder.setOnInfoListener (null); mRecorder.setPreviewDisplay (null); mRecorder.stop ();} catch (IllegalStateException e) {/ / TODO: handle exception Log.i ("Exception", Log.getStackTraceString (e)) } catch (RuntimeException e) {/ / TODO: handle exception Log.i ("Exception", Log.getStackTraceString (e));} catch (Exception e) {/ / TODO: handle exception Log.i ("Exception", Log.getStackTraceString (e));} / / added by ouyang end mRecorder.release (); mRecorder = null; upRecord ();}} public String newFileName () {mFileName = Environment.getExternalStorageDirectory () .getAbsolutePath () String s = new SimpleDateFormat ("yyyy-MM-dd hhmmss") .format (new Date ()); return mFileName + = "/ rcd_" + s + ".mp3";}}

This is selected from my code, plus permissions should be possible.
