I will copy the snippet

11/24/2016, 9:49 AM

you want to set

null

to field that not accept nulls, that is the problem

11/24/2016, 9:50 AM

looks like a cast

(null as TextView)

11/24/2016, 9:50 AM

oh sorry cast

null

to not-nullable type

11/24/2016, 9:51 AM

@User uploaded a file: Untitled

11/24/2016, 9:51 AM

I understand the problem with the cast

11/24/2016, 9:51 AM

When I run the app is all runnig ok

11/24/2016, 9:51 AM

private val mLabel by lazy { findViewById(R.id.navigation_section_title) as TextView? }

11/24/2016, 9:52 AM

the issue is just on Android Studio

11/24/2016, 9:52 AM

no)) issue is in the code

11/24/2016, 9:52 AM

try to writing lazy init yourself

11/24/2016, 9:53 AM

private lateinit var …

after inflation:

mLabel = findViewById(…)

11/24/2016, 9:53 AM

it also will be more efficient because default Kotlin’s

lazy

is synchronized

11/24/2016, 9:54 AM

Ok I'm going to try

Thank you so much

I tried the @miha-x64's solution but I got the same result

11/24/2016, 10:01 AM

@stepango advice throws my spected result

11/24/2016, 10:02 AM

I had the preview but without the setted value for the label

11/24/2016, 10:03 AM

finally, I just figure it out, I had my ids like :

<layout_descriptor>.<view_name>

11/24/2016, 10:04 AM

<TextView
            android:id="@+id/sexy_view.title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>

aapt shouldn’t allow this

11/24/2016, 10:04 AM

The dot there is making the problem u.U

11/24/2016, 10:05 AM

i just replaced it and now is all going perfect

11/24/2016, 10:05 AM

11/24/2016, 10:05 AM

I used my entire life

11/24/2016, 10:05 AM

for strings too

11/24/2016, 10:05 AM

android:text="@string/internal.example.dummy"

11/24/2016, 10:06 AM

don’t know, just saying it shouldn’t 🙂
