这是一个日期小例子
import java.util.Calendar;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.TimePicker;
public class DatePicker_TimePicker extends Activity {
TextView textView;
// 声明DatePicker对象
DatePicker datePicker;
// 声明TimePicker对象
TimePicker timePicker;
// 创建Calendar类
Calendar c;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.date_time);
// 获得日期实例
c = Calendar.getInstance();
// 实例化组件
Button button1 = (Button) this.findViewById(R.id.button1);
Button button2 = (Button) this.findViewById(R.id.button2);
textView = (TextView) this.findViewById(R.id.date_textview);
datePicker = (DatePicker) this.findViewById(R.id.DatePicker);
timePicker = (TimePicker) this.findViewById(R.id.TimePicker);
// DatePicker对象的设置
// 将日历初始化为当前系统时间，并设置其事件监听
datePicker.init(c.get(Calendar.YEAR), c.get(Calendar.MONTH),
c.get(Calendar.DAY_OF_MONTH), new DatePicker.OnDateChangedListener() {
@Override
public void onDateChanged(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
// 当日期更改时，在这里处理
// c.set(year, monthOfYear,dayOfMonth);
}
});
// TimePicker对象
timePicker.setIs24HourView(true);
// 设置监听事件改变
timePicker
.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay,
int minute) {
// TODO Auto-generated method stub
// 时间改变时处理
// c.set(year, month,day,hourOfDay,minute,second);
// c.set(hourOfDay, minute);
}
});
// button1事件
button1.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
new DatePickerDialog(DatePicker_TimePicker.this,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
// c.set(year, monthOfYear, dayOfMonth);
}
}, c.get(Calendar.YEAR),
c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH)).show();
}
});
// button2事件
button2.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
new TimePickerDialog(DatePicker_TimePicker.this,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
// c.set(hourOfDay, minute);
}
}, c.get(Calendar.HOUR_OF_DAY), c.get(Calendar.MINUTE), true)
.show();
}
});
}
}
下面是xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="@+id/date_textview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/text_title" />
<DatePicker
android:id="@+id/DatePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TimePicker
android:id="@+id/TimePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/date" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/time" />
</LinearLayout>
效果如下：
