前言
我把录音分成了两部分
1.UI界面，弹窗读秒
2.一个类（包含开始、停止、创建文件名功能）
第一部分
由于6.0权限问题，点击按钮申请权限通过则弹窗，如何申请权限
弹窗布局popw_record.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <RelativeLayout android:layout_width="match_parent" android:layout_height="260dp" android:layout_marginLeft="50dp" android:layout_marginRight="50dp" android:background="@drawable/take_phone" android:orientation="vertical"> <ImageView android:id="@+id/close" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:padding="10dp" android:src="@mipmap/guanbi" /> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginLeft="50dp" android:layout_marginRight="50dp" android:gravity="center" android:orientation="vertical"> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@mipmap/luyin" /> <Chronometer android:id="@+id/timer" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="20dp" android:format="%s" /> <TextView android:id="@+id/startRecord" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/playrecord" android:layout_marginTop="20dp" android:background="@color/background" android:padding="10dp" /> LinearLayout> RelativeLayout>LinearLayout>弹弹弹
/** * 开始录音 */ private void showPopup() { final View contentView = LayoutInflater.from(Orderdeatil.this).inflate(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://松开事件发生后执行代码的区域 if (mPopWindow != null) { mPopWindow.dismiss(); sr.stopRecording(); } break; case MotionEvent.ACTION_DOWN://按住事件发生后执行代码的区域 Chronometer timer = (Chronometer) contentView.findViewById(R.id.timer); timer.setBase(SystemClock.elapsedRealtime());//计时器清零 timer.start();//开始录音的提示 sr.startRecording(); break; case MotionEvent.ACTION_CANCEL: if (mPopWindow != null) { mPopWindow.dismiss(); sr.stopRecording();//停止录音 } 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).inflate(R.layout.activity_orderdeatil, null); mPopWindow.showAtLocation(rootview, Gravity.CENTER, 0, 0); }第二部分 工具类
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 { // 准备好开始录音 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 { //下面三个参数必须加，不加的话会奔溃，在mediarecorder.stop(); //报错为：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"; } }这是从我代码中择出来的，加上权限应该是可以的。
