在我的應用程序中，我有兩個複選框之一是PayByCredit和多一個是PaybySMS對於這兩個複選框不可見是什麼問題？要顯示覆選框我給這樣的代碼android:visibility="visible"，但仍然沒有用。任何人都可以幫我解決這個問題嗎？Android Check Box可見性問題？

請幫我出這個問題的？
你用什麼佈局XML？ – Mike
有可能這個錯誤在你的'layout-xml'中（你應該把它貼出來）。 F.E.複選框在高度爲'fill_parent'的佈局下面。因此請將複選框設置爲綠色背景並檢查您是否看到它 – longilong
@Mike，我正在使用Relativelayout。 – user3744932
