一、前言 昨天完成了加載頁(yè)，星球頁(yè)的設(shè)計(jì)，學(xué)習(xí)了Fragment實(shí)現(xiàn)底部導(dǎo)航欄。 今天將Cardview與傳感器結(jié)合起來(lái)，實(shí)現(xiàn)了發(fā)布表可以跟隨手機(jī)晃動(dòng)。學(xué)習(xí)了Fragment的嵌套實(shí)現(xiàn)了我的頁(yè)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(guò)查閱資料，修改包解決問(wèn)題；Fragment沒(méi)有很好的理解，導(dǎo)致在嵌套中出現(xiàn)了困難，通過(guò)查閱資料與重學(xué)Fragment實(shí)現(xiàn)嵌套，UI頁(yè)面方面出現(xiàn)問(wèn)題，不知如何具體下去。 明天對(duì)登錄注冊(cè)頁(yè)面進(jìn)行美化，以及學(xué)習(xí)頭部標(biāo)題欄的運(yùn)用。 二、成果展示
