Android日期选择器实现年月日 * 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;
}

}
