前言
前面我们已经使用 uiautomator2 成功连接到手机了，我们还需要一个工具来查看手机App上的元素，另外该项目作者也针对 uiautomator2 写了一个工具 weditor ，我们可以使用该工具来查看元素。
更多的介绍，大家可以前往 Github 进行学习：https://github.com/openatx/weditor
安装 weditor
通过 Python 的 pip 工具进行安装，命令如下：pip install --pre weditor 。

启动成功后，浏览器会默认打开一个Web网页：http://localhost:17310 ，之后我们将在该页面查看元素。
需要注意的是，我们在使用过程中，不要把命令行窗口关闭，否则将不能在上面Web页面中查看元素。
为了更方便使用，我们也可以创建启动 weditor 的快捷方式图标，执行命令：python -m weditor --shortcut 。
(venv) D:pycharmCodeatxDemo2venvScripts>python -m weditor --shortcut
Shortcut created. C:UserswintestDesktopWEditor.lnk
weditor 连接手机
首先，在命令行窗口输入命令：adb devices 查看连接状态，确保手机已经连接上电脑。
D:>adb devices
List of devices attached
c01bcd5d device
接着在Web页面上，点击 Connect 按钮，当看到出现一个绿色的小叶子，就说明连接成功。
页面元素定位
接下来，我们根据上面的计算器来对页面元素的定位进一步说明和实践。
- ResourceId 定位
# 点击键盘的数字 1
d(resourceId="com.sec.android.app.popupcalculator:id/bt_01").click()
# 点击键盘的加号 +
d(resourceId="com.sec.android.app.popupcalculator:id/bt_add").click()
- Text 定位
# 点击键盘的数字 5
d(text="5").click()
# 点击键盘的等号 =
d(text="=").click()
- Description 定位
# 点击键盘的加号 +
d(description="加号").click()
# 点击键盘的等号 =
d(description="等于").click()
- ClassName 定位
# 点击计算器最上方的文本区域
d(className="android.widget.EditText").click()
- XPath 定位
# 点击键盘的数字 1，对应 ResourceId 属性
d.xpath('//*[@resource-id="com.sec.android.app.popupcalculator:id/bt_01"]').click()
# 点击键盘的加号 1，对应 Text 属性
d.xpath('//*[@text="1"]').click()
# 点击键盘的等号 =，对应 Description 属性
d.xpath('//*[@content-desc="等于"]').click()
- 坐标 定位
# 点击键盘的数字 1，坐标大致为 (0.1, 0.8)
d.click(0.1, 0.8)
# 点击键盘的等号 =，坐标大致为 (0.8, 0.9)
d.click(0.8, 0.9)
