Set the tint of an ImageView using databinding

I use databinding to set the tint of my ImageView. And this is working well :

android:tint="@{plantEntity.isFavorite ? @color/favorite : @color/favorite_none}" />

The problem is android:tint is deprecated. When I try to use app:tint instead, I have this error :

Cannot find a setter for <android.widget.ImageView app:color> that accepts parameter type 'int'

If a binding adapter provides the setter, check that the adapter is annotated correctly and that the parameter type matches.

Why and what I have to do ? Create a BindingAdapter ?

Solution

  • similar to what has been discussed on Tint does not work <21 version in DataBinding

    add a binding adapter:

    @JvmStatic
@BindingAdapter("app:tint")
fun ImageView.setImageTint(@ColorInt color: Int) {
  setColorFilter(color)
}

    and you don't have to use any compat if your minSdk is > 21 (which is a good deal anyway in 2021 you should not support anything below 26)

    anyhow .. this seems to be a fug on the androidx.databinding expression https://issuetracker.google.com/issues/152953070
