1. 前言

public void touch(By selector, TouchPressType type)
    {
        Point p = getElementCenter(selector);
        mDevice.getImpl().touch(p.x, p.y, type);
    }

public boolean visible(By selector)
    {
        ViewNode node = selector.findView(mHierarchyViewer);
        return mHierarchyViewer.visible(node);
    }

2. EaysyMonkeyDevice API List and Sample

EasyMonkeyDevice是在MonkeyDevice和HierarchyViewer的基础上出来的一个类，按照本人的理解，主要增加的功能就是：

• 在MonkeyDevice和HierarchyViewer的基础上针对部分API增加了对控件ID的支持以操作控件

3. EasyMonkeyDevice vs MonkeyDevice API Mapping Matrix

4. EasyMonkeyDevice vs HierarchyViewer Mapping Matrix

5. EasyMonkeyDevice Standalone API
