安卓開發(fā)實(shí)戰(zhàn)-記賬本APP（四）

今天實(shí)現(xiàn)的內(nèi)容有：添加賬本信息，個(gè)人頭像的切換，密碼的修改，退出登錄。

添加賬本信息有三個(gè)功能：

①記一筆支出項(xiàng)目

②記一筆收入項(xiàng)目

③清空所有項(xiàng)目


在此期間遇到的困難有：Activity與Fragment之間數(shù)值的傳遞問題，我利用Bundle對(duì)象來進(jìn)行傳值，但是布局文件中fragment里的name=“Account_Fragment”，這里暫時(shí)沒有想到如何傳值。

因此暫時(shí)將name="Find_Message"這個(gè)還未改變的一個(gè)fragment，當(dāng)再次點(diǎn)擊Account圖標(biāo)時(shí)，就可以傳進(jìn)去參數(shù)。

未解決的事：

①記完賬本后，按日期排序一直不對(duì)

②初始Fragment沒辦法傳參

明天要做的事：

先將上述問題解決，在設(shè)置長按項(xiàng)目進(jìn)行單獨(dú)刪除。

統(tǒng)計(jì)總的收入與支出的對(duì)比

找到合適的圖標(biāo)進(jìn)行替換

學(xué)習(xí)hellochart，將數(shù)據(jù)以餅狀圖展示。

?

今日成果：



?



?點(diǎn)擊更換頭像：會(huì)有幾個(gè)頭像供選擇



?

?當(dāng)點(diǎn)擊后自動(dòng)跳回個(gè)人信息界面：



?

?其次是更換密碼：需要輸入原密碼與新密碼



?

?再者就是記賬的頁面：有支出，收入，刪除所有，支出的會(huì)顯示紅色，收入的會(huì)顯示綠色



?

?當(dāng)點(diǎn)擊收入時(shí)，會(huì)彈出一個(gè)框來進(jìn)行記賬



?

?同理，當(dāng)點(diǎn)擊支出時(shí)，也會(huì)彈出一個(gè)框



?

?當(dāng)點(diǎn)擊刪除所有時(shí)，會(huì)將所有賬目全部刪除。
