onSaveInstanceState恢复Activity/Fragment/View状态

• onCreate(Bundle savedInstanceState)
• onSaveInstanceState(Bundle outState)
  onPause() -> onSaveInstanceState() -> onStop()
  调用时机，Activity 容易被销毁的时候调用：
  • 按下Home键 : Activity 进入了后台, 此时会调用该方法;
  • 按下电源键 : 屏幕关闭, Activity 进入后台;
  • 启动其它 Activity : Activity 被压入了任务栈的栈底;
  • 横竖屏切换 : 会销毁当前 Activity 并重新创建;
• onRestoreInstanceState(Bundle savedInstanceState)
