XML tool properties in Android

I'm a porter.

In summary, the tool property is intended to preview the layout effect in the IDE.

Example: We added a textview in the layout, in order to preview the effect, we might add

Android:text = "This is a test"

But often after previewing we will forget to delete this code. In the face of this, we can use the tool property

Tool:text = "This is a test"

We can get the results we want when we preview, and this property will be ignored at runtime.
