背景：
本文通过代码实现listview滑动功能，主要适于用自己开发的自动化测试
预备知识：
adb shell sendevent /dev/input/event0 3 0 110 //x坐标
adb shell sendevent /dev/input/event0 3 1 70 //y坐标
adb shell sendevent /dev/input/event0 1 330 1 //按下状态，准确的说是有压力值
adb shell sendevent /dev/input/event0 0 0 0 //必要的一行数据
adb shell sendevent /dev/input/event0 1 330 0 //抬起状态，无压力值
adb shell sendevent /dev/input/event0 0 0 0 //必要的一行，相当于终止一段完整数据的标致
模拟滑动轨迹
如下例是画出一条开始于（100,200），止于（108,200）的水平直线
adb shell sendevent /dev/input/event0 3 0 100 //start from point (100,200)
adb shell sendevent /dev/input/event0 3 1 200
adb shell sendevent /dev/input/event0 1 330 1 //touch
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 3 0 101 //step to point (101,200)
adb shell sendevent /dev/input/event0 0 0 0
…………………… //must list each step, here just skip
adb shell sendevent /dev/input/event0 3 0 108 //end point(108,200)
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 1 330 0 //untouch
adb shell sendevent /dev/input/event0 0 0 0
核心代码：
注：下面代码只实现了从下往上拖拽的功能，至于向左、向右、向下拉等均可参照修改
