移動應用開發

Activity組件通信

一、實驗目的及要求：
（1） 掌握顯示啟動和隱式啟動的方式
（2） 掌握Activity間的資料通信

二、實驗內容及步驟任務：根據下述要求實作對應程式
1、 完成啟動界面的設計，要求采用合理布局，使界面效果與圖1所示結果保持一致，
（ “男”單選按鈕默認選中，學院下拉串列框的內容為：資訊技術學院、外國語學院、機電學院、商學院、藝術設計學院、珠寶學院、新聞傳播學院）；左列標簽名字體大小為24sp；點擊“使用顯示啟動”按鈕和“使用隱式啟動”按鈕，均能跳轉至界面
2，如圖2所示，前者使用顯示啟動方式，后者使用隱式啟動方式，兩種啟動方式均將界面1中的資料傳遞至界面2中，
