1、因为Android界面上的全部控件一般都位于Layout控件（比方RelativeLayout）之上，而布局控件能够设置响应touch事件，所以能够通过布局控件的setOnTouchListen来截获touch事件。做进一步的处理。

2、关于界面滑动。涉及到gesture的处理，而gesture（手势）是touch事件的更高一层的事件，能够将touch事件传入GestureDetector对象进行处理，而创建GestureDetector对象，要首先创建OnGestureListener对象，在OnGestureListener的OnFling函数中能够进行手势识别。

3、详细流程。

实现OnTouchListen和OnGestureListen两个抽象类，同一时候实现当中的抽象函数就可以。

（1）IntellisenseActivity中继承抽象类

（2）创建布局控件RelativeLayout的id为relativelayout

（3）代码编写
