实现日历控件:
- <RelativeLayout
- android:id="@+id/layout_calendar"
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:visibility="visible" >
- <TextView
- android:id="@+id/calendarCenter"
- style="@style/main_bar_text_style"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_centerHorizontal="true"
- android:layout_margin="8dp" />
- <ImageButton
- android:id="@+id/calendarLeft"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_alignParentLeft="true"
- android:padding="8dp"
- android:contentDescription="@null"
- android:src="@drawable/calendar_month_left"
- android:background="@null"/>
- <ImageButton
- android:id="@+id/calendarRight"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_alignParentRight="true"
- android:padding="8dp"
- android:contentDescription="@null"
- android:src="@drawable/calendar_month_right"
- android:background="@null"/>
- <com.techrare.view.CalendarView
- android:id="@+id/calendar"
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:layout_alignParentLeft="true"
- android:layout_below="@+id/calendarCenter" />
- </RelativeLayout>
<RelativeLayout android:id="@+id/layout_calendar" android:layout_width="fill_parent" android:layout_height="wrap_content" android:visibility="visible" > <TextView android:id="@+id/calendarCenter" style="@style/main_bar_text_style" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_margin="8dp" /> <ImageButton android:id="@+id/calendarLeft" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:padding="8dp" android:contentDescription="@null" android:src="@drawable/calendar_month_left" android:background="@null"/> <ImageButton android:id="@+id/calendarRight" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:padding="8dp" android:contentDescription="@null" android:src="@drawable/calendar_month_right" android:background="@null"/> <com.techrare.view.CalendarView android:id="@+id/calendar" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_below="@+id/calendarCenter" /> </RelativeLayout>
- <style name="main_bar_text_style">
- <item name="android:textColor">@color/white</item>
- <item name="android:textStyle">bold</item>
- <item name="android:textSize">18sp</item>
- </style>
<style name="main_bar_text_style"> <item name="android:textColor">@color/white</item> <item name="android:textStyle">bold</item> <item name="android:textSize">18sp</item> </style>
上一月图片:
- 调用 calendar.clickLeftMonth();
调用 calendar.clickLeftMonth();
下一月:
- 调用 calendar.clickRightMonth();
调用 calendar.clickRightMonth();
日历控件中的一些功能(可以自己加):
- //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();
- }
- }
//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{@Overridepublic 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!
