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

[java] view
plain copy

<?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_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:<pre name="code" class="java">package com.example.user.mydate;

import android.app.Activity;

import android.view.Gravity;

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;

}

}
