安卓实验报告班级:xxxxx学号:姓名:xxxx实验一:Activity生命周期的测试一:实验目的掌握使用Eclipse开发Android应用开发程序的方法;掌握Android虚拟设备的创建方法;了解Android的程序结构;了解使用命令行创建Android程序方法;了解Activity生命周期,理解Activity事件回调,onRestoreInstanceState()和onSaveInstanceState两个函数的使用。二:实验设备Eclipse开发Android应用Android虚拟设备(AVD)三:实验内容(1)正常启动ActivityLife,然后单击用户界面的“结束程序”按钮关闭程序。(2)正常启动ACtivityLife,然后通过“拨号键”启动内置的拨号程序,再通过“回退建”退出拨号程序,使ActivityLife重新显示在屏幕中。四:.;;;;;;;;;;;;;;lassMainActivityextendsActivity{privatestaticStringTAG="LIFECYCLE";***@OverrideprotectedvoidonCreate(BundlesavedInstanceState){(savedInstanceState);setContentView();(TAG,"(1)onCreate()");Buttonbutton=(Button)findViewById();(newOnClickListener(){ publicvoidonClick(Viewview){ //TODOAuto-generatedmethodstub finish(); } });}***@OverrideprotectedvoidonStart(){ //TODOAuto-generatedmethodstub ();(TAG,"(2)onStart()");}***@OverrideprotectedvoidonRestoreInstanceState(BundlesavedInstanceState){ //TODOAuto-generatedmethodstub (savedInstanceState);(TAG,"(3)onRestoreInstanceState()");}***@OverrideprotectedvoidonResume(){ //TODOAuto-generatedmethodstub ();(TAG,"(4)onResume()");}***@OverrideprotectedvoidonSaveInstanceState(BundleoutState){ //TODOAuto-generatedmethodstub (outState);(TAG,"(5)onSaveInstanceState()");}***@OverrideprotectedvoidonRestart(){ //TODOAuto-generatedmethodstub ();(TAG,"(6)onRestart()");}***@OverrideprotectedvoidonPause(){ //TODOAuto-generatedmethodstub ();(TAG,"(7)onPause()");}***@OverrideprotectedvoidonStop(){ //TODOAut
