本文实例为大家分享了java获取不同路径的方法，供大家参考，具体内容如下
思路：
自定义button
获取DialogManager、Au@R_404_6901@Manager setonLongClickListener长按事件--做好Au@R_404_6901@Manager的录音准备工作
Au@R_404_6901@Manager.setonAu@R_404_6901@StateListener(this)实现录音准备完毕的接口回调方法，方法中去发送MSG_AU@R_404_6901@_PREPARE消息代表录音准备工作完毕
在mHandler中接收消息，开始开启线程录音，并且计时，计时的过程中，去发送MSG_VOICE_CHANGED消息，去updateVoiceLeve更新音量图标，另外在MotionEvent.ACTION_UP事件中，去定义au@R_404_6901@FinishRecorderListener.onFinish接口方法，方法是录音完毕的回调方法，在MainActivity中，mAu@R_404_6901@Recorderbutton.setAu@R_404_6901@FinishRecorderListener实现录音完毕回调方法去更新ListVIEwUi界面
点击ListVIEwItem条目播放动画， MediaManager.playSound并且播放音频
