前言
安卓的按壓效果的傳統(tǒng)方式是shape.xml文件卦尊，不過如果當(dāng)項(xiàng)目比較多按鈕都需要自定義按壓效果的話，shape.xml的數(shù)量可是非常頭疼的（即使是ctrl c+ ctrlv）腾窝，故此可以采用動(dòng)態(tài)方式進(jìn)行按壓效果的實(shí)現(xiàn)。
上代碼
/**

* @param RADIUS
* 角度
* @param normalFileName
* 正常顏色
* @param pressFileName
* 點(diǎn)擊顏色
* @param type
* -1:left 0:center 1:right 2:四角圓角

小結(jié)
小建議，建一個(gè)獲取不同按壓效果的管理類虹脯，這樣就可以統(tǒng)一入口替換資源圖片了驴娃。歡迎各位大神有更好的做法分享到評(píng)論區(qū)~
