一、前言
最近項(xiàng)目里面需要用到多個(gè)seekbar并且需要顯示不同的精度，于是參考了部分博客模仿華為的天氣刻度盤添加了精度控制和自己定義的seekbar實(shí)現(xiàn)了如下效果(畫面模糊是因?yàn)殇浿艷if圖的工具導(dǎo)致的)。
本控件最低兼容到API16 更低的版本沒有g(shù)etThumb()函數(shù)
二、刻度盤部分
1.刻度：刻度的繪制類似于繪制時(shí)鐘刻度繪制出一條刻度通過旋轉(zhuǎn)canvas繪制出其他刻度
2.波浪：波浪的繪制是通過兩個(gè)正弦函數(shù)y = Asin(wx+b)+h 實(shí)時(shí)變換sin的初相
3.精度控制：通過設(shè)定 精度模式，最大進(jìn)度值和顯示的最大值共同決定。最大進(jìn)度值/當(dāng)前進(jìn)度值=實(shí)際顯示的最大值/當(dāng)前顯示的值

三、自定義seekbar
1.thumb（滑塊）：通過擴(kuò)展已有的seekbar控件獲取滑塊位置并且通過canvas繪制圖像和進(jìn)度的數(shù)值
2.進(jìn)度線：進(jìn)度線條是一個(gè)圓角的矩形通過滑塊的位置繪制矩形的長(zhǎng)度,滑塊左邊一根右邊一根拼起來
3.尺寸的確定都是基于滑塊而繪制的所以在初始化時(shí)需要先有一個(gè)確定尺寸的滑塊，我是在drawable中定義的一個(gè)只有尺寸的滑塊，這樣做的缺陷在于在XML布局文件中的android:layout_height="" 任何設(shè)置均無效設(shè)置成wrap_content即可，要調(diào)整大小就修改drawable中繪制的滑塊的尺寸
4.精度控制：原理同刻度盤精度控制
