系统 1383 0
本人利用WheelView写的一个DatePickerDialog
（还有一个TimePickerDialog，本人忘了在写在哪个项目里了，等找到了也贴上来）

先看图，有个直观的了解

基于WheelView自定义的DatePickerDialog


DatePickerDialog代码：

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
