Android原生控件中时间日期是分开的,但是有时我们的实际工作中可能是需要两个联动选择的,这时就需要我们自己将两个控件组合起来封装了一个工具类.

一. 创建工具类

关于控件主题以原生为主,大家可以修改themeId进行对应修改,上图就分别是主题2和主题4.绑定控件直接将TextView类型修改为对应控件对象就行.

package com.myllcn.specialdeal;

import android.annotation.SuppressLint;

import android.app.DatePickerDialog;

import android.app.TimePickerDialog;

import android.content.Context;

import android.os.Build;

import android.support.annotation.RequiresApi;

import android.widget.DatePicker;

import android.widget.EditText;

import android.widget.TextView;

import android.widget.TimePicker;

import java.util.Calendar;

public class DateTimePicker implements DatePickerDialog.OnDateSetListener,TimePickerDialog.OnTimeSetListener{

private static Context context;

private static DatePickerDialog datePickerDialog;

private static TimePickerDialog pickerDialog;

private static Calendar calendar;

private static TextView editText; // 绑定控件

private String dt = "";

Integer themeId = 2; // 主题ID

@SuppressLint("ResourceType")

@RequiresApi(api = Build.VERSION_CODES.N)

public void init(Context context1, TextView editText1)

{

calendar=Calendar.getInstance();

editText=editText1;

context=context1;

datePickerDialog=new DatePickerDialog(context,themeId,this, calendar.get(Calendar.YEAR), calendar

.get(Calendar.MONTH), calendar

.get(Calendar.DAY_OF_MONTH));

datePickerDialog.show();

}

@Override

public void onDateSet(DatePicker view, int year, int month, int day) {

dt = String.valueOf(new StringBuilder()

.append(year)

.append("-")

.append((month + 1) < 10 ? "0"

+ (month + 1) : (month + 1))

.append("-")

.append((day < 10) ? "0" + day : day));

// editText.setText( );

initTimePicker(context);

}

public void initTimePicker(Context context1){

context=context1;

pickerDialog=new TimePickerDialog(context,themeId,this,8,00,true);

pickerDialog.show();

}

@Override

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

String s=(hourOfDay<10?"0"+hourOfDay:hourOfDay)+":"+(minute<10?"0"+minute:minute)+ ":"+ "00";

dt = dt +" "+s;

editText.setText(dt);

}

}

二. 使用:

// 1.创建工具类对象

final DateTimePicker dateTimePicker = new DateTimePicker();

//2.引用对象的init方法

dateTimePicker.init(context, textView);

context: 上下文对象

textview: 我们需要绑定textview对象,如果想要适应editText,那么需要将第一步工具类里面的数据类型也换成edittext.

三. 如果还需要获取事件日期选择完的事件,那么可以采用addTextChangedListener监听.

textView.addTextChangedListener(new TextWatcher() {

@Override

public void beforeTextChanged(CharSequence s, int start, int count, int after) {

}

@Override

public void onTextChanged(CharSequence s, int start, int before, int count) {

}

@Override

public void afterTextChanged(Editable s) {

}

});
