Android/Kotlin databinding error during runtime

Question

When you use a included layout

<include android:id="@+id/included" layout="@layout/content_fft"/>

and use

mBinding = DataBindingUtil.setContentView(this, R.layout.activity_record)

I see this

but it builds and runs properly .

Does anyone has a clue how to get rid of it. It's very annoying because Android Studio shows me a lot of errors.

To demonstrate the error, I made a demo repo https://github.com/hannesa2/AndroidBinding3.2

Answer 1

mBinding的类型错误，应为ActivityRecordBinding。

private lateinit var mBinding: ActivityRecordBinding

Answer 2

Just be sure if your layout file name is in snake_case then your binding class name would be in CamelCase .

For example

Layout Name is activity_main.xml

Binding class name would be ActivityMainBinding.class

So your binding class name will be ActivityRecordBinding .
