如何實現Android自定義日期段選擇控件功能

發布時間：2020-08-01 10:07:52 來源：億速云閱讀：622 作者：小豬欄目：移動開發

這篇文章主要講解了如何實現Android自定義日期段選擇控件功能，內容清晰明了，對此有興趣的小伙伴可以學習一下，相信大家閱讀完之后會有幫助。

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

當時做的時候有幾個需求：1.當天為最大的結束日期，2.最大選擇范圍1年，3.開始時間和結束時間可以為同一天。如有其他需求實現，可以參考代碼改進一下。先上效果圖：

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

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
