01）首次进入时

    01-01 01:29:17.473 I/LockScreenSettings( 7727): LockScreenSettings onCreate
    01-01 01:29:17.482 I/LockScreenSettings( 7727): LockScreenSettings onCreateView
    01-01 01:29:17.483 I/LockScreenSettings( 7727): LockScreenSettings onStart
    01-01 01:29:17.488 I/LockScreenSettings( 7727): LockScreenSettings onResume

02）上锁时或home回到桌面时

01-01 01:32:13.394 I/LockScreenSettings( 7727): LockScreenSettings onPause
01-01 01:32:13.449 I/LockScreenSettings( 7727): LockScreenSettings onStop

03）解锁时

01-01 01:32:55.346 I/LockScreenSettings( 7727): LockScreenSettings onStart
01-01 01:32:55.378 I/LockScreenSettings( 7727): LockScreenSettings onResume

04）按小返回时

01-01 01:34:47.918 I/LockScreenSettings( 7727): LockScreenSettings onPause
01-01 01:34:48.101 I/LockScreenSettings( 7727): LockScreenSettings onStop

01-01 01:34:48.101 I/LockScreenSettings( 7727): LockScreenSettings onDestroyView

另注：onPause和onResume成对，onStop和onStart一双。下为一个简单重载的方法代码

        /*onCreate是指创建该fragment，类似于Activity.onCreate，你可以在其中初始化除了view之外的东西；     onCreateView是创建该fragment对应的视图，你必须在这里创建自己的视图并返回给调用者。     部分代码在onCreateView中调用super.onCreateView。     其实有没有调用都无所谓，因为super.onCreateView是直接返回null的。*/           @Override        public void onCreate(Bundle savedInstanceState) {            super.onCreate(savedInstanceState);            Log.i(TAG,"LockScreenSettings onCreate");        }     @Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {     // 加载布局文件             layout = inflater.inflate(R.layout.bird_lockscreen_sign_setting, container,false);             Log.i(TAG,"LockScreenSettings onCreateView");             return layout;}@Overridepublic void onResume() {    super.onResume();            Log.i(TAG,"LockScreenSettings onResume");}        @Overridepublic void onPause() {    super.onPause();    Log.i(TAG,"LockScreenSettings onPause");}@Overridepublic void onStart() {    super.onStart();    Log.i(TAG,"LockScreenSettings onStart");}        @Overridepublic void onStop() {    super.onStop();    Log.i(TAG,"LockScreenSettings onStop");}    @Override    public void onDestroyView() {        super.onDestroyView();        Log.i(TAG,"LockScreenSettings onDestroyView");    }
