我使用https://github.com/bulletnoid/StaggeredGridView這個庫來製作pinterest風格的佈局,並在此佈局上使用pulltorefresh。 ı有一個滑動菜單可供選擇不同的類別,並根據用戶選擇的類別,刷新並再次填充。StaggeredGridView只能正確刷新頂部
Pulltorefresh工作正常。
如果用戶頂部的佈局和選擇幻燈片菜單上的類別它的工作正常。但是,如果用戶在佈局的底部並在幻燈片菜單上選擇一個類別,它的工作就不正確。
場景,頂部佈局和選擇類別的幻燈片菜單和填充交錯佈局。它的正常工作
的情況下,對slidemenu佈局和選擇類別的底部和填充交錯的佈局。它無法正常工作

StaggeredGridView是一個開源項目,那麼你爲什麼不看看源代碼來看看哪裏出了問題?如果確實存在錯誤,請添加問題或分叉項目,修復問題並提出合併請求。開源不僅是免費使用某人的代碼,而且也是關於貢獻。 – Egor
對不起ı假設有人使用這個庫,並爭奪相同的問題。也可能是我的baseadapter或某個地方的錯誤。我只是想告訴我我錯在哪裏。並感謝您提供有關在github上開放問題的建議。 –
@MustafaErturk你有關於這個問題的解決方案嗎? –
