我從我的產品列表中獲取服務器的顏色代碼，顏色代碼越來越完美，但我試圖將其設置在我的textview但無法設置color，以下是我的代碼段代碼和adapter，任何幫助將不勝感激。如何使用顏色代碼使用JSON

顏色代碼，我從服務器獲取

    { 
     "colors": [ 
      "#000000", 
      "#7E3517", 
      "#C85A17"

這取決於你的顏色是存儲在您'JSONArray' ...是十六進制RGB的方式嗎？ –

我的顏色代碼是這種格式的＃000000 –

@BartoszLipinski參見我編輯的問題 –

，你需要以這種方式來使用它（如果它是十六進制代碼，如＃000000，#ffffff）

holder.firstcolor.setBackgroundColor(Color.parseColor(first));

論據parseColor將接受字符串，所以請小心爲

但firstcolor是int，..見 –

是@Lakhan我糾正了這一點，並提及它 –

它說java.lang。 NumberFormatException：無效int：「＃000000」 –
