要開發Android 程式，一定先了解其程式執行的生命週期

利用Log 這個類別，做一下事件驅動測試

   public  void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        Log.d("Activity_LifeCycle","onCreate");

    }

    protected  void onStart() {

        super.onStart();

        Log.d("Activity_LifeCycle","onStart");

     }

    protected  void onResume() {

        super.onStart();

        Log.d("Activity_LifeCycle","onResume");

     }

    protected  void onPause() {

        super.onStart();

        Log.d("Activity_LifeCycle","onPause");

     }

    protected  void onStop() {

        super.onStart();

        Log.d("Activity_LifeCycle","onStop");

     }

    protected  void onRestart() {

        super.onStart();

        Log.d("Activity_LifeCycle","onRestart");

     }

    protected  void onDestroy() {

        super.onStart();

        Log.d("Activity_LifeCycle","onDestroy");

     }
