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、AudioManager setOnLongClickListener长按事件--做好AudioManager的录音准备工作

AudioManager.setOnAudioStateListener(this)实现录音准备完毕的接口回调方法，方法中去发送MSG_AUDIO_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audioFinishRecorderListener.onFinish接口方法，方法是录音完毕的回调方法，在MainActivity中，mAudioRecorderButton.setAudioFinishRecorderListener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

activity_main.xml

dialog_recorder.xml---dialog布局文件

item_recorder.xml--listview中的每个item
