简介

下面以一个让用户选择日期、时间的例子来示范DatePicker和TimePicker的功能和用法

step1:新建一个项目DateAndTimePicker

step2:编写应用的UI界面 /layout/main.xml

[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextViewandroid:layout_width="fill_parent"
android:layout_height="wrap_content"android:text="选择购买此书的具体时间"/>
<DatePickerandroid:id="@+id/datePicker"
android:layout_width="wrap_content"android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"/>
<TimePickerandroid:id="@+id/timePicker"
android:layout_width="wrap_content"android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"/>
<EditTextandroid:layout_width="fill_parent"
android:layout_height="wrap_content"android:editable="false"
android:cursorVisible="false"
android:id="@+id/show"/>
</LinearLayout>

step3:主程序MainActivity.java

[java] view plain copy

packagecn.roco.picker;
importjava.util.Calendar;
importandroid.app.Activity;
importandroid.os.Bundle;
importandroid.widget.DatePicker;
importandroid.widget.DatePicker.OnDateChangedListener;
importandroid.widget.EditText;
importandroid.widget.TimePicker;
importandroid.widget.TimePicker.OnTimeChangedListener;
publicclassMainActivityextendsActivity{
privateintyear;
privateintmonth;
privateintday;
privateinthour;
privateintminute;
/**Calledwhentheactivityisfirstcreated.*/
@Override
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
DatePickerdatePicker=(DatePicker)findViewById(R.id.datePicker);
TimePickertimePicker=(TimePicker)findViewById(R.id.timePicker);
Calendarcalendar=Calendar.getInstance();
year=calendar.get(Calendar.YEAR);
month=calendar.get(Calendar.MONTH);
day=calendar.get(Calendar.DAY_OF_MONTH);
hour=calendar.get(Calendar.HOUR);
minute=calendar.get(Calendar.MINUTE);
datePicker.init(year,month,day,newOnDateChangedListener(){
@Override
publicvoidonDateChanged(DatePickerview,intyear,intmonth,
intday){
MainActivity.this.year=year;
MainActivity.this.month=month;
MainActivity.this.day=day;
//显示时间
showDate(year,month,day,hour,minute);
}
});
timePicker.setOnTimeChangedListener(newOnTimeChangedListener(){
@Override
publicvoidonTimeChanged(TimePickerview,inthour,intminute){
MainActivity.this.hour=hour;
MainActivity.this.minute=minute;
//显示时间
showDate(year,month,day,hour,minute);
}
});
}
privatevoidshowDate(intyear,intmonth,intday,inthour,intminute){
EditTextshow=(EditText)findViewById(R.id.show);
show.setText("您的购买日期为:"+year+"年"+month+"月"+day+"日"+hour
+"时"+minute+"分");
}
}

step4:部署应用到模拟器上，并选择日期和时间
