Android自定義帶增長動(dòng)畫和點(diǎn)擊彈窗提示效果的柱狀圖DEMO
更新時(shí)間：2016年11月09日 10:32:03 作者：zzd_92
這篇文章主要介紹了Android自定義帶增長動(dòng)畫和點(diǎn)擊彈窗提示效果的柱狀圖的相關(guān)資料,非常不錯(cuò)具有一定的參考借鑒價(jià)值，需要的朋友可以參考下
項(xiàng)目中最近用到各種圖表，本來打算用第三方的，例如MPAndroid,這是一個(gè)十分強(qiáng)大的圖表庫，應(yīng)用起來十分方便，但是最終發(fā)現(xiàn)和設(shè)計(jì)不太一樣，沒辦法，只能自己寫了。今天將寫好的柱狀圖的demo貼在這，該柱狀圖可根據(jù)數(shù)據(jù)的功能有一下幾點(diǎn)：
1. 根據(jù)數(shù)據(jù)的多少，動(dòng)態(tài)的繪制柱狀圖柱子的條數(shù)；
2. 柱狀圖每條柱子的繪制都有動(dòng)態(tài)的動(dòng)畫效果；
3. 每條柱子有點(diǎn)擊事件，點(diǎn)擊時(shí)彈出提示框，顯示相關(guān)信息，規(guī)定時(shí)間后，彈窗自動(dòng)消失。
好了，先上演示圖：
