实现方法：
1.在xml文件中添加
2.别忘了申请录音权限
AndPermission.with(MainActivity.this) .permission(Manifest.permission.RECORD_AUDIO,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE) .onGranted(permissions -> { showSelect(); }) .onDenied(permissions -> { Toast.makeText(MainActivity.this,"请同意录音权限",Toast.LENGTH_SHORT).show(); }) .start();private void showSelect() { SoundTextView recordAudio = findViewById(R.id.record_audio); recordAudio.setOnRecordFinishedListener(new SoundTextView.OnRecordFinishedListener() { @Override public void newMessage(String path, int duration) { int index = path.lastIndexOf("/"); String fileName = path.substring(index + 1); Log.e("录音文件", "path=: "+path ); } }); }使用方法如上非常简单：
