Android仿ios录音动画

太懒了，以前没有记录过开发用到的技术，时间久了发现脑子很乱，会什么接触过什么都无法想起，所以。。。

开整

1.先定义所需动画以dialog形式管理

2.自定义Button对其按下移动弹起事件进行管理

3.调用系统的MediaRecorder实现录音功能

只列出部分源码，下有源码地址

public class VideoButton extends Button {
Context context;
private VedioDialog dialog;//语音动画dialog
private Float onKeyDown,onKeyMove;//按下时坐标，移动后坐标
private long onKeyDownTime,OnKeyUpTime,recordTime;//按下时间，弹起时间,录音时间
private AudioRecorder mAudioRecorder;//实例录音
private boolean IsRecordOn = false;//是否在录音
private boolean IsCancle = false;//是否取消录音
private RecordListener listener;
private String path;

public VideoButton(Context context) {
super(context);
// TODO Auto-generated constructor stub
init(context);
}
public VideoButton(Context context, AttributeSet attrs) {

}

private void init(Context context) {
this.context = context;
this.setText(R.string.video_hold_speak);
dialog = new VedioDialog(context);

dialog.setOnDismissListener(new OnDismissListener() {

@Override

// TODO Auto-generated method stub

}
});

}
