实现日历控件：

[html]

  1. <RelativeLayout  
  2.     android:id="@+id/layout_calendar"  
  3.     android:layout_width="fill_parent"  
  4.     android:layout_height="wrap_content"  
  5.     android:visibility="visible" >  
  7.     <TextView  
  8.         android:id="@+id/calendarCenter"  
  9.         style="@style/main_bar_text_style"  
  10.         android:layout_width="wrap_content"  
  11.         android:layout_height="wrap_content"  
  12.         android:layout_centerHorizontal="true"  
  13.         android:layout_margin="8dp" />  
  15.     <ImageButton  
  16.         android:id="@+id/calendarLeft"  
  17.         android:layout_width="wrap_content"  
  18.         android:layout_height="wrap_content"  
  19.         android:layout_alignParentLeft="true"  
  20.         android:padding="8dp"  
  21.         android:contentDescription="@null"  
  22.         android:src="@drawable/calendar_month_left"   
  23.         android:background="@null"/>  
  25.     <ImageButton  
  26.         android:id="@+id/calendarRight"  
  27.         android:layout_width="wrap_content"  
  28.         android:layout_height="wrap_content"  
  29.         android:layout_alignParentRight="true"  
  30.         android:padding="8dp"  
  31.         android:contentDescription="@null"  
  32.         android:src="@drawable/calendar_month_right"   
  33.         android:background="@null"/>  
  35.     <com.techrare.view.CalendarView  
  36.         android:id="@+id/calendar"  
  37.         android:layout_width="fill_parent"  
  38.         android:layout_height="wrap_content"  
  39.         android:layout_alignParentLeft="true"  
  40.         android:layout_below="@+id/calendarCenter" />  
  41. </RelativeLayout>  


[html]

  1. <style name="main_bar_text_style">  
  2.     <item name="android:textColor">@color/white</item>  
  3.     <item name="android:textStyle">bold</item>  
  4.     <item name="android:textSize">18sp</item>  
  5. </style>  



上一月图片：

北京联动北方科技有限公司

[java]


调用 calendar.clickLeftMonth();   

调用 calendar.clickLeftMonth();

     

下一月：

北京联动北方科技有限公司

[java]


调用 calendar.clickRightMonth();   

调用 calendar.clickRightMonth();



日历控件中的一些功能（可以自己加）：

[java]
//获取日历控件对象   

  1. calendar = (CalendarView)findViewById(R.id.calendar); 
  2. //获取日历中年月 ya[0]为年，ya[1]为月（格式大家可以自行在日历控件中改） 
  3. String[] ya = calendar.getYearAndmonth().split("-"); 
  4. //点击上一月 同样返回年月 
  5. String leftYearAndmonth = calendar.clickLeftMonth(); 
  6. String[] lya = leftYearAndmonth.split("-"); 
  7. //点击下一月 
  8. String rightYearAndmonth = calendar.clickRightMonth(); 
  9. String[] rya = rightYearAndmonth.split("-"); 
  10. //设置控件监听，可以监听到点击的每一天（大家也可以在控件中自行设定） 
  11. calendar.setOnItemClickListener(new calendarItemClickListener()); 
  12. class calendarItemClickListener implements OnItemClickListener{ 
  13.        @Override 
  14.        public void OnItemClick(Date date) { 
  15.              Toast.makeText(getApplicationContext(), date+"", Toast.LENGTH_SHORT).show(); 
  16.        } 
  17.  } 


//获取日历控件对象
calendar = (CalendarView)findViewById(R.id.calendar);
//获取日历中年月 ya[0]为年，ya[1]为月（格式大家可以自行在日历控件中改）
String[] ya = calendar.getYearAndmonth().split("-");
//点击上一月 同样返回年月
String leftYearAndmonth = calendar.clickLeftMonth();
String[] lya = leftYearAndmonth.split("-");
//点击下一月
String rightYearAndmonth = calendar.clickRightMonth();
String[] rya = rightYearAndmonth.split("-");
//设置控件监听，可以监听到点击的每一天（大家也可以在控件中自行设定）
calendar.setOnItemClickListener(new calendarItemClickListener());
class calendarItemClickListener implements OnItemClickListener{
       @Override
       public void OnItemClick(Date date) {
             Toast.makeText(getApplicationContext(), date+"", Toast.LENGTH_SHORT).show();
       }
}



这些功能只是配合项目中的需要来添加的，大家如有其他需求，可以自行在控件中添加，应该也不怎么困难.
