A modern programming language that makes developers happier.

kotlinlang

```
@BindingAdapter("android:languageColor")
fun TextView.languageColor(color: String?) {
```

Usage

```
android:languageColor="@{repo.primaryLanguage.color}"
```

I’ve verified that
• TextView is the correct class (not appcompat)
• Input is nullable (also tried `Any?`)

And I’ve tried the label as `languageColor`.

The IDE correctly autosuggests the name, but I’m getting the error:

```
****/ data binding error ****msg:Cannot find the setter for attribute 'android:languageColor' with parameter type java.lang.String on android.widget.TextView.
```

Edit: Also just checked and it works fine with java

You can't put that in android namespaces.

You can, but usually it is confusing, better to omit namespace and use app or any own namespace (we use bind for custom bindings or methods, not related on view static attributes)

The examples actually used the android namespace. I ended up removing namespaces in declaration and used `app:` within the xml. Problem was with missing `kapt`
