開發(fā)中碰到個需求，需要在一個空間中選擇完成開始和結(jié)束時間。實現(xiàn)的過程走的是程序員開發(fā)的老路子，找到輪子后自己改吧改吧就成了。

當(dāng)時做的時候有幾個需求：1.當(dāng)天為最大的結(jié)束日期，2.最大選擇范圍1年，3.開始時間和結(jié)束時間可以為同一天。如有其他需求實現(xiàn)，可以參考代碼改進(jìn)一下。先上效果圖：

視頻點擊后的虛影是屏幕錄制的原因。實現(xiàn)步驟：(如有缺失什么資源，請告知。開始時間和結(jié)束時間顯示自己布局內(nèi)添加就可以)

1.自定義控件屬性

<declare-styleable name='MyCalendar'> <attr name='dateformat' format='string'></attr> <attr name='titleSize' format='dimension'></attr> <attr name='titleColor' format='color'></attr> <attr name='goIcon' format='reference'></attr> <attr name='preIcon' format='reference'></attr> <attr name='dayInMonthColor' format='color'></attr> <attr name='dayOutMonthcolor' format='color'></attr> <attr name='todayColor' format='color'></attr> <attr name='todayEmptycircleColor' format='color'></attr> <attr name='todayFillcircleColor' format='color'></attr> <attr name='calendarbackground' format='color|reference'></attr></declare-styleable>

2.自定義控件代碼

3.自定義view用到的布局 appoint_calendarview.xml，對應(yīng)日歷控件如下面圖片的部分。

定義控件選擇后的背景部分：CalendarDayRelativeLayout.java

自定義控件內(nèi)日期的CalendarDayTextView.java
