一、前言

　　昨天完成了加載頁，星球頁的設計，學習了Fragment實現(xiàn)底部導航欄。

　　今天將Cardview與傳感器結合起來，實現(xiàn)了發(fā)布表可以跟隨手機晃動。學習了Fragment的嵌套實現(xiàn)了我的頁面上“我的發(fā)帖”與“我的回帖”的切換。遇到的困難：一些控件或者版本之間的沖突，通過查閱資料，修改包解決問題；Fragment沒有很好的理解，導致在嵌套中出現(xiàn)了困難，通過查閱資料與重學Fragment實現(xiàn)嵌套，UI頁面方面出現(xiàn)問題，不知如何具體下去。

　　明天對登錄注冊頁面進行美化，以及學習頭部標題欄的運用。
