本文以实例讲述了android中DatePicker和TimePicker的使用方法，具体步骤如下：
下面是实现具体功能的代码，其中main.xml代码为：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="请选择购买本书的具体时间" />
<DatePicker
android:id="@+id/datePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal" />
<TimePicker
android:id="@+id/timePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal" />
<EditText
android:id="@+id/show"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:cursorVisible="false"
android:editable="false" />
</LinearLayout>
java代码为：
public class AndroidDemo5Activity extends Activity {
// 记录当前的时间
private int year;
private int month;
private int day;
private int hour;
private int minute;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
DatePicker date = (DatePicker) findViewById(R.id.datePicker);
TimePicker time = (TimePicker) findViewById(R.id.timePicker);
// 或许当前的年月日，小时，分钟
Calendar ca = Calendar.getInstance();
year = ca.get(Calendar.YEAR);
month = ca.get(Calendar.MONTH);
day = ca.get(Calendar.DAY_OF_MONTH);
hour = ca.get(Calendar.HOUR);
minute = ca.get(Calendar.MINUTE);
// 初始化DatePicker
date.init(year, month, day, new OnDateChangedListener() {
@Override
public void onDateChanged(DatePicker arg0, int year, int month,
int day) {
AndroidDemo5Activity.this.year = year;
AndroidDemo5Activity.this.month = month;
AndroidDemo5Activity.this.day = day;
// 显示当前时间和日期
showDate(year, month, day, hour, minute);
}
});
// 为TimerPicker指定事件监听器
time.setOnTimeChangedListener(new OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker arg0, int hour, int minute) {
AndroidDemo5Activity.this.hour = hour;
AndroidDemo5Activity.this.minute = minute;
}
});
}
protected void showDate(int year2, int month2, int day2, int hour2,
int minute2) {
EditText text = (EditText) findViewById(R.id.show);
text.setText("您的购买时间为：" + year2 + "年" + month2 + "月" + day2 + "日"
+ hour2 + "时" + minute2 + "分");
}
}
运行效果如下图所示：
