I feel like a newbi but cant find any answer :slightly_smiling_face:

I’m having issues with my own data binding adapter.

I have this adapter code:

@BindingAdapter(“value”)
fun setValue(view: TextView, value: Float?) {
    view.text = value.toString()
}

and this in the XML:

 &lt;TextView
            android:id=“@+id/result”
            android:value=“@{viewModel.value}”
            android:textSize=“128sp”/&gt;

viewModel.value is a LiveData&lt;Float&gt;()

And I’m getting this message:

Found data binding errors.
****/ data binding error ****msg:Cannot find the setter for attribute ‘android:value’ with parameter type android.arch.lifecycle.MutableLiveData&lt;java.lang.Float&gt; on android.widget.TextView.  ****\ data binding error ****

What I am missing?

in the annotation you said only `@BindingAdapter("value")` you should use `app:value="@{viewModel.value}` in the xml then.
If you want to use "android:value" add the android prefix to the annotation like `@BindingAdapter("android:value")`

Can you set lifecycleOwner on your binding?
