同样是为了解决有些时候采用uiautomater不能点击某个控件的问题，新增布局文件解析接口。

主要作用：代码中无法查找到控件时，我们使用dump布局文件，此段代码主要解析dump文件，可根据任意UiObeject的任意属性，获取它其余的属性。

例如布局文件下有text为Play music的控件，想获取其位置，具体效果如下：

import org.dom4j.Element;

/**
 * 数据实体类
 *
 * @author ***
 */
public class XMLBean {

public final Element element;
public final int index;
public final String text;
public final String resourceId;
public final String classText;
public final String packageText;
public final String contentDesc;
public final boolean checkable;
public final boolean checked;
public final boolean clickable;
public final boolean enable;
public final boolean focusable;
public final boolean focused;
public final boolean scrollable;
public final boolean long_clickable;
public final boolean password;
public final boolean selected;
public final String bounds;

public XMLBean(Element element) {
this.element = element;

index = Integer.parseInt(element.attributeValue("index"));
text = element.attributeValue("text");
resourceId = element.attributeValue("resource-id");
classText = element.attributeValue("class");
packageText = element.attributeValue("package");
contentDesc = element.attributeValue("content-desc");
checkable = Boolean.parseBoolean(element.attributeValue("checkable"));
checked = Boolean.parseBoolean(element.attributeValue("checked"));
clickable = Boolean.parseBoolean(element.attributeValue("clickable"));
enable = Boolean.parseBoolean(element.attributeValue("enabled"));
focusable = Boolean.parseBoolean(element.attributeValue("focusable"));
focused = Boolean.parseBoolean(element.attributeValue("focused"));
scrollable = Boolean.parseBoolean(element.attributeValue("scrollable"));
long_clickable = Boolean.parseBoolean(element.attributeValue("long-clickable"));
password = Boolean.parseBoolean(element.attributeValue("password"));
selected = Boolean.parseBoolean(element.attributeValue("selected"));
bounds = element.attributeValue("bounds");

}

@Override
public String toString() {
return "XMLBean [index=" + index + ", text=" + text + ", resourceId=" + resourceId + ", classText="
+ classText + ", packageText=" + packageText + ", contentDesc=" + contentDesc
+ ", checkable=" + checkable + ", checked=" + checked + ", clickable=" + clickable
+ ", enable=" + enable + ", focusable=" + focusable + ", focused=" + focused
+ ", scrollable=" + scrollable + ", long_clickable=" + long_clickable + ", password="
+ password + ", selected=" + selected + ", bounds=" + bounds + "]";
}

}
