今天学习日期控件和时间控件

效果图：

activity_main.xml中的代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <!-- 日期 -->    <DatePicker        android:id="@+id/datePicker1"        android:calendarViewShown="false"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <!-- 时间 -->    <TimePicker        android:id="@+id/timePicker1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"                 /></LinearLayout>

代码解析：

android:calendarViewShown="false" 取消日历的属性

MainActivity.java中的代码：

package com.example.datepickerdemo;import java.util.Calendar;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.widget.DatePicker;import android.widget.DatePicker.OnDateChangedListener;import android.widget.TimePicker;import android.widget.TimePicker.OnTimeChangedListener;import android.widget.Toast;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);Calendar calendar = Calendar.getInstance();int year = calendar.get(Calendar.YEAR);int month = calendar.get(Calendar.MONTH);int day = calendar.get(Calendar.DAY_OF_MONTH);datePicker.init(year, month, day, new OnDateChangedListener() {@Overridepublic void onDateChanged(DatePicker view, int year,int monthOfYear, int dayOfMonth) {// TODO Auto-generated method stubToast.makeText(MainActivity.this,"您选择的日期是：" + year + "年" + (monthOfYear + 1) + "月"+ dayOfMonth + "日!", Toast.LENGTH_LONG).show();}});TimePicker timePicker = (TimePicker) findViewById(R.id.timePicker1);timePicker.setIs24HourView(true) ;//解决屏幕显示时间是24小时制，还是12小时制timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {@Overridepublic void onTimeChanged(TimePicker view, int hourOfDay, int minute) {// TODO Auto-generated method stubToast.makeText(MainActivity.this,"您选择的时间是：" + hourOfDay + "时" + minute + "分!",Toast.LENGTH_LONG).show();}});}}
