Android编程之DatePicker和TimePicke简单时间监听用法分析

本文实例讲述了Android编程之DatePicker和TimePicke简单时间监听用法。分享给大家供大家参考，具体如下：

DatePicker和TimePicker都是从FrameLayout派生而来。

简单的例子实现对时间监听。

<?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:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="选择时间"
 />
 <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/et"
   android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:editable="false"
 android:cursorVisible="false"
 />
</LinearLayout>

package com.ly;
import java.util.Calendar;
import android.app.Activity;
import android.os.Bundle;
import android.widget.DatePicker;
import android.widget.DatePicker.OnDateChangedListener;
import android.widget.EditText;
import android.widget.TimePicker;
import android.widget.TimePicker.OnTimeChangedListener;
/**

* 两个时间控件监听

*/
public class TimeExampleActivity extends Activity {
 private int year;
 private int month;
 private int day;
 private int hour;
 private int minute;
 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main);
   DatePicker datapicker = (DatePicker) findViewById(R.id.datepicker);
   TimePicker timepicker =(TimePicker) findViewById(R.id.timepicker);
   Calendar c =Calendar.getInstance();
   year =c.get(Calendar.YEAR);
   month=c.get(Calendar.MONTH);
   day=c.get(Calendar.DAY_OF_MONTH);
   hour = c.get(Calendar.HOUR);
   minute =c.get(Calendar.MINUTE);
   datapicker.init(year, month, day, new OnDateChangedListener() {
     @Override
     public void onDateChanged(DatePicker view, int year, int monthOfYear,
         int dayOfMonth) {
   TimeExampleActivity.this.year=year;
   TimeExampleActivity.this.month=monthOfYear;
   TimeExampleActivity.this.day=dayOfMonth;
   showDate(year,month,day,hour,minute);
     }
   });
   timepicker.setOnTimeChangedListener(new OnTimeChangedListener() {
     @Override
     public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
       // TODO Auto-generated method stub
       TimeExampleActivity.this.hour=hourOfDay;
       TimeExampleActivity.this.minute=minute;
     }
   });
 }
 private void showDate(int year, int month, int day, int hour,int minute) {
   EditText et = (EditText) findViewById(R.id.et);
   et.setText(year+"年"+month+"月"+day+"日"+hour+"时"+minute+"分");
 }
}

运行效果如图：

希望本文所述对大家Android程序设计有所帮助。
