Android日期选择器实现年月日三级联动

最近项目里面用到了一个日期选择器，实现现在主流的WheelView滑动选择，整理了下，做了个Demo.废话不多说，直接上代码.

主布局：activity_main.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 xmlns:tools="http://schemas.android.com/tools" 
 android:layout_width="match_parent" 
 android:layout_height="match_parent" 
 android:paddingBottom="@dimen/activity_vertical_margin" 
 android:paddingLeft="@dimen/activity_horizontal_margin" 
 android:paddingRight="@dimen/activity_horizontal_margin" 
 android:paddingTop="@dimen/activity_vertical_margin" 
 tools:context="com.example.user.mydate.MainActivity"> 
 
 <TextView 
  android:id="@+id/selectDate" 
  android:layout_width="match_parent" 
  android:layout_height="30dp" 
  android:gravity="center" 
  android:onClick="selectDate" 
  android:clickable="true" 
  android:text="日期选择" /> 
</RelativeLayout>

MainActivity:

package com.example.user.mydate; 
 
import android.app.Activity; 
import android.os.Bundle; 
import android.view.Gravity; 
import android.view.View; 
import android.view.Window; 
import android.widget.TextView; 
import android.widget.Toast; 
 
import com.example.user.mydate.view.ChangeDatePopwindow; 
 
public class MainActivity extends Activity { 
 
 private TextView selectDate; 
 @Override 
 protected void onCreate(Bundle savedInstanceState) { 
  super.onCreate(savedInstanceState); 
  requestWindowFeature(Window.FEATURE_NO_TITLE); 
  setContentView(R.layout.activity_main); 
  selectDate= (TextView) findViewById(R.id.selectDate); 
 } 
 
 public void selectDate(View v){ 
  if (v.getId()==R.id.selectDate){ 
   selectDate(); 
  } 
 
 } 
 
 
 private String[] selectDate() { 
  final String[] str = new String[10]; 
  ChangeDatePopwindow mChangeBirthDialog = new ChangeDatePopwindow( 
    this); 
  mChangeBirthDialog.setDate("2016", "1", "1"); 
  mChangeBirthDialog.showAtLocation(selectDate, Gravity.BOTTOM, 0, 0); 
  mChangeBirthDialog.setBirthdayListener(new ChangeDatePopwindow.OnBirthListener() { 
 
   @Override 
   public void onClick(String year, String month, String day) { 
    // TODO Auto-generated method stub 
    Toast.makeText(MainActivity.this,year + "-" + month + "-" + day,Toast.LENGTH_LONG).show(); 
    StringBuilder sb = new StringBuilder(); 
    sb.append(year.substring(0, year.length() - 1)).append("-").append(month.substring(0, day.length() - 1)).append("-").append(day); 
    str[0] = year + "-" + month + "-" + day; 
    str[1] = sb.toString(); 
    selectDate.setText(year + "-" + month + "-" + day); 
 
   } 
  }); 
  return str; 
 } 
 
}

主要的类：
