Kotlin synthetic extension and several include same layout

Question

How to access to view using kotlin synthetic extension if I have a layout like below:

file:two_days_view.xml

Answer 1

As a general rule of thumb, you should not construct layouts that end up having multiple views with the same id - for this very reason.

But, to solve your problem: Instead of importing

kotlinx.android.synthetic.main.layout.day_row.*

you can import

kotlinx.android.synthetic.main.layout.day_row.view.* (Notice the additional .view at the end).

This will import the views not as properties on the Activity/Fragment level, but instead as extension properties for View. That way, you can do it the way you want, assuming that day1 and day2 contain the views you want:

day1.dayName.text = "xxx"
day2.dayName.text = "sss"

Answer 2

In this case, use:

(day1 as TextView).text = ""
(day2 as TextView).text = ""
