这里有新鲜出炉的精品教程,程序狗速度看过来!

Android移动端操作系统

Android是一种基于Linux的自由及开放源代码的操作系统,主要使用于移动设备,如智能手机和平板电脑,由Google公司和开放手机联盟领导及开发。尚未有统一中文名称,中国大陆地区较多人使用“安卓”或“安致”。


这篇文章主要介绍了Android中TimePicker时间选择与DatePicker日期选择组件的使用实例,这两个组件加上去的效果就是我们平时在iOS上设置闹钟时调整时间类似的滚动选项,需要的朋友可以参考下

效果和代码都非常直观:

实例1:TimePicker


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  xmlns:tools="http://schemas.android.com/tools" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  android:paddingBottom="@dimen/activity_vertical_margin" 
  android:paddingLeft="@dimen/activity_horizontal_margin" 
  android:paddingRight="@dimen/activity_horizontal_margin" 
  android:paddingTop="@dimen/activity_vertical_margin" 
  tools:context=".MainActivity" > 
   
   
  <TimePicker  
    android:id="@+id/timePic1" 
    android:layout_height="wrap_content" 
    android:layout_width="match_parent"/> 
  <Button  
    android:id="@+id/buttone1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/timePic1" 
    android:text="获取TimePick时间"/> 
   
</RelativeLayout> 

package com.android.xiong.times; 
 
import android.os.Bundle; 
import android.app.Activity; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.TimePicker; 
import android.widget.TimePicker.OnTimeChangedListener; 
 
public class MainActivity extends Activity { 
   
   
  private TimePicker timePick1; 
  private Button buttone1; 
 
  @Override 
  protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    timePick1=(TimePicker)findViewById(R.id.timePic1); 
     
    buttone1=(Button)findViewById(R.id.buttone1); 
    OnChangeListener buc=new OnChangeListener(); 
    buttone1.setOnClickListener(buc); 
    //是否使用24小时制 
    timePick1.setIs24HourView(true); 
    TimeListener times=new TimeListener(); 
    timePick1.setOnTimeChangedListener(times); 
  } 
   
  class OnChangeListener implements OnClickListener{ 
    @Override 
    public void onClick(View v) { 
      // TODO Auto-generated method stub 
      int h=timePick1.getCurrentHour(); 
      int m=timePick1.getCurrentMinute(); 
      System.out.println("h:"+h+"  m:"+m); 
    } 
  } 
  class TimeListener implements OnTimeChangedListener{ 
     
    /** 
     * view 当前选中TimePicker控件 
     * hourOfDay 当前控件选中TimePicker 的小时 
     * minute 当前选中控件TimePicker 的分钟 
     */ 
    @Override 
    public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { 
      // TODO Auto-generated method stub 
      System.out.println("h:"+ hourOfDay +" m:"+minute); 
    } 
     
  } 
  @Override 
  public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
  } 
 
} 

实例2:DatePicker


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  xmlns:tools="http://schemas.android.com/tools" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  android:paddingBottom="@dimen/activity_vertical_margin" 
  android:paddingLeft="@dimen/activity_horizontal_margin" 
  android:paddingRight="@dimen/activity_horizontal_margin" 
  android:paddingTop="@dimen/activity_vertical_margin" 
  tools:context=".MainActivity" > 
 
  <DatePicker  
    android:id="@+id/datePick1" 
    android:layout_height="wrap_content" 
    android:layout_width="match_parent" 
    /> 
  <Button  
    android:id="@+id/button1" 
    android:layout_below="@id/datePick1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="获取DatePicker的值"/> 
 
</RelativeLayout> 


package com.android.xiong.datepicker; 
 
import android.os.Bundle; 
import android.app.Activity; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.DatePicker; 
 
public class MainActivity extends Activity { 
 
  private DatePicker datePicker1; 
  private Button button1; 
  @Override 
  protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    datePicker1=(DatePicker)findViewById(R.id.datePick1); 
    //设置默认的时间 比如2055年 9月9日 
    datePicker1.updateDate(2012, 8, 9); 
    button1=(Button)findViewById(R.id.button1); 
    OnClicLisers cl=new OnClicLisers(); 
    button1.setOnClickListener(cl); 
  } 
 
  class OnClicLisers implements OnClickListener{ 
    @Override 
    public void onClick(View v) { 
      // TODO Auto-generated method stub 
      int y=datePicker1.getYear(); 
      int m=datePicker1.getMonth()+1; 
      int d=datePicker1.getDayOfMonth(); 
      System.out.println("y:"+y+" m:"+m+" d:"+d); 
       
    } 
  } 
  @Override 
  public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
  } 
 
}
