* Activity的基类

* Usage:
* 1、发送广播：{@link #sendBroadcastMsg(Class)}
* 2、接受广播重写：{@link #receiverBroadcastMsg(Intent)}
* 3、加载Activity content layout {@link #inflateContentViewById()}
* 4、侧滑退出Activity {@link #isSupportSlideBack()}
* 5、设置点击事件：{@link #setCommonClickListener(View)}
* 6、接受点击事件：{@link #onClickImpl(View)}
* 7、设置Activity action title：{@link #setActionTitle(String)}
* 8、是否展示头部布局：{@link #showAppActionBar()}
* 9、是否支持点击焦点控件外的区域进行隐藏软键盘：{@link #isSupportHideOutside()} 焦点控件的设置 {....}
* 10、启动Activity：附带默认动画{@link #startActivityByDefaultAnim(Intent)}
* Transition ---> 启动位置调用：{@link #startActivityTransition(Intent)}
* 目标位置调用：{@link #showDefaultActivityTransition()}{@link #showFadeActivityTransition()}
* {@link #showBoundActivityTransition()} {@link #showExplodeActivityTransition()}.
