Appium 的 UIAutomator2 模式下使用 sendKeys 出现错误。

测试积点老人

问题描述
使用Appium做UI自动化测试，因为要获取到Toast信息，就用了UIAutomator2模式。登录App后，有一个设置6个密码的步骤。如下图

上面有阴影的地方就是用来输入密码。布局如下图：

我一开始的做法是想直接获取到“android.widget.LinearLayout” 然后输入6个数字的字符串。Appium能定位到元素的位置，但使用sendKey时候报了如下的错误：

然后我尝试定位下一级的每一个控件，然后输入密码，但还是显示是同一个错误。

第一个方法中，在Appium默认的模式下，也就是appium是可以输入内容的。
请问有什么方法可以在UIAutomator2模式下向非TextFiled控件进行sendKeys操作?。

项目环境
node.js version:v10.12.0
appium server version:v1.10.0
platform:Android
Android-Version:6.0
