DatePicke和rTimePicker 一个日期小例子

 

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);
//组件
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"
    >

//文本组件
<TextView
android:id="@+id/date_textview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/text_title"
/> 
// 数据选择   
<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：
