Delphi XE10讓android的介面設計擺脫繁雜

標籤：

設計一個選項卡。

大體圖樣：

 

1、建立一個multi_Device_Application;2、在form上放一個Rectangle1，設定align為top。設定fill屬性的kind為Gradient，編輯Gradient（顏色取值見樣圖）。3、再放一個Rectange2設定align為top,底色為白色。4、在Rectange2上放置三個RoundRect1，RoundRect2，RoundRect3。設定它們的Corners屬性的TopLeft和TopRight為TURE,BottomLeft和BottomRight為FALSE，則圓角出現了。然後分別設定它們的Fill屬性。5、放置一個Tabcontrol控制項，設定TopPostion為None;align為client。6、設定RoundRect1，RoundRect2，RoundRect3的tag屬性分別為:1,2,3
