安卓開發實戰-記帳本APP（四）

今天實現的內容有：添加帳本信息，我的頭像的切換，密碼的修改，退出登陸。

添加帳本信息有三個功能：

①記一筆支出項目

②記一筆收入項目

③清空全部項目

在此期間遇到的困難有：Activity與Fragment之間數值的傳遞問題，我利用Bundle對象來進行傳值，可是佈局文件中fragment裏的name=「Account_Fragment」，這裏暫時沒有想到如何傳值。

所以暫時將name="Find_Message"這個還未改變的一個fragment，當再次點擊Account圖標時，就能夠傳進去參數。

未解決的事：

①記完帳本後，按日期排序一直不對

②初始Fragment沒辦法傳參

明天要作的事：

先將上述問題解決，在設置長按項目進行單獨刪除。

統計總的收入與支出的對比

找到合適的圖標進行替換

學習hellochart，將數據以餅狀圖展現。

 

今日成果：

 

 點擊更換頭像：會有幾個頭像供選擇

 

 當點擊後自動跳回我的信息界面：

 

 其次是更換密碼：須要輸入原密碼與新密碼

 

 再者就是記帳的頁面：有支出，收入，刪除全部，支出的會顯示紅色，收入的會顯示綠色

 

 當點擊收入時，會彈出一個框來進行記帳

 

 同理，當點擊支出時，也會彈出一個框

 

 當點擊刪除全部時，會將全部帳目所有刪除。
