1.介绍DatePicker和TimePicker两种实现动态输入日期和时间的功能
2.介绍DataPickerDialog和TimePickerDialog两种实现动态输入日期和时间的对话框
3，介绍两组针对监测日期时间改变的监听器包含：
OnDataChangedListener和OnTimeChangedListener()
OnDataSetListener和OnTimeSetListener()
>当用户更改了DataPicker里的年，月，日时，将触发OnDataChangedListener监听器的OnDataChange()事件
>当用户更改了TimePicker里的时，，分时，将触发OnTimeChangedListener监听器的OnTimeChanged()事件
>当用户更改了DataPickerDialog里的年，月，日时，将触发OnDataSetListener监听器的onDataSet()事件
>当用户更改了TimePickerDialog里的时，分时，将触发OnTimeSetListener监听器的onTimeSet()事件
1.xml布局：两个空间DatePicker 和TimePicker
<RelativeLayout xmlns:android="" xmlns:tools="" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" > <DatePicker android:id="@+id/datePicker1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="20dp" android:layout_alignParentLeft="true" android:layout_alignParentRight="true" android:layout_alignParentTop="true" /> <TimePicker android:id="@+id/timePicker1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/datePicker1" android:layout_centerHorizontal="true" android:layout_marginTop="20dp" /></RelativeLayout>
2.java代码部分
public class MainActivity extends Activity {private DatePicker datePicker;private TimePicker timePicker;private Calendar cal;private int year;private int month;private int day;private int hour;private int minute;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//获取一个日历对象cal = Calendar.getInstance();//获取年月日时分秒的信息year = cal.get(Calendar.YEAR);month = cal.get(Calendar.MONTH)+1;day = cal.get(Calendar.DAY_OF_MONTH);hour = cal.get(Calendar.HOUR_OF_DAY);minute = cal.get(Calendar.MINUTE);setTitle(year + "-" + month + "-" + day + " " + hour + ":" + minute);datePicker = (DatePicker) findViewById(R.id.datePicker1);timePicker = (TimePicker) findViewById(R.id.timePicker1);//datePicker初始化datePicker.init(year, cal.get(Calendar.MONTH), day, new OnDateChangedListener() {@Overridepublic void onDateChanged(DatePicker view, int year, int monthOfYear,int dayOfMonth) {// TODO Auto-generated method stubsetTitle(year + "-" + (monthOfYear + 1) + "-" + dayOfMonth);}});timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {@Overridepublic void onTimeChanged(TimePicker view, int hourOfDay, int minute) {// TODO Auto-generated method stubsetTitle(hourOfDay + ":" + minute);}});new DatePickerDialog(this, new OnDateSetListener() {@Overridepublic void onDateSet(DatePicker view, int year, int monthOfYear,int dayOfMonth) {// TODO Auto-generated method stubsetTitle(year + "-" + (monthOfYear + 1) + "-" + dayOfMonth);}}, year, cal.get(Calendar.MONTH), day).show();new TimePickerDialog(this, new OnTimeSetListener() {@Overridepublic void onTimeSet(TimePicker view, int hourOfDay, int minute) {// TODO Auto-generated method stubsetTitle(hourOfDay + ":" + minute);}}, hour, minute, true).show();}}
