電商、商城類APP經常使用標籤"hot"--第三方開源--LabelView

 

LabelView是在github上一個開源的標籤庫。其項目主頁是:https://github.com/linger1216//labelview 
LabelView爲一個TextView,ImageView或者爲ListView中適配器getView返回的View,增長一個左上角或者右上角的標籤android

這種需求設計在商城類APP、電商類APP中比較經常使用,這些APP展現的商品,一般會增長一些促銷或者該類商品的特徵。
LabelView集成自Android TextView,能夠像使用Android TextView同樣使用LabelView,LabelView使用簡單,如代碼所示:git
