安卓實驗報告

1、安卓實驗報告班級：xxxxx學號：姓名：xxxx實驗一：Activity生命周期的測試一：實驗目的掌握使用Eclipse開發(fā)Android應用開發(fā)程序的方法；掌握Android虛構設施的創(chuàng)立方法；認識Android的程序構造；認識使用命令行創(chuàng)立Android程序方法；認識Activity生命周期，理解Activity事件回調，onRestoreInstanceState()和onSaveInstanceState兩個函數的使用。二：實驗設施Eclipse開發(fā)Android應用Android虛構設施（AVD）三：實驗內容1）正常啟動ActivityLife，而后單擊用戶界面的“結束程序”按鈕封閉

2、程序。2）正常啟動ACtivityLife，而后經過“撥號鍵”啟動內置的撥號程序，再經過“回退建”退出撥號程序，使ActivityLife從頭顯示在屏幕中。四：實驗核心代碼packageclassMainActivityextendsActivityprivatestaticStringTAG=LIFECYCLE;OverrideprotectedvoidonCreate(BundlesavedInstanceState)(savedInstanceState);setContentView(TAG,(1)onCreate();Buttonbutton=(Button)findViewById
