前言:
公司項(xiàng)目彈窗的地方比較多蜒什,彈窗的樣式也有很多種测秸,所以就根據(jù)項(xiàng)目里的多種彈窗樣式,整合成一個(gè)可重復(fù)利用的全局彈窗灾常,可自己手動(dòng)再次自定義霎冯。
有多種樣式:最簡(jiǎn)單的文字提示彈窗(有標(biāo)題、詳細(xì)信息钞瀑,還有確定沈撞、取消按鈕,這些皆可單獨(dú)存在)雕什,首頁(yè)一張大廣告圖片彈窗缠俺,有單選显晶、多選(列表多選)、勾選彈窗壹士,輸入框彈窗(可以自己修改為幾個(gè)輸入框都行)磷雇,TextView彈窗,還有圖片和文字結(jié)合的說(shuō)明彈窗躏救,還有自定義彈窗(可以自行添加想要添加到彈窗上的視圖)唯笙;彈窗右上角有關(guān)閉按鈕,可以自行選擇是否展示盒使,等等功能自行探索.....
具體可以自己嘗試崩掘,先說(shuō)一下最簡(jiǎn)單的文字提示彈窗,如下圖所示:
部分具體實(shí)現(xiàn)如下:
