Android中日期选择器怎么实现三级联动，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
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：
