How to write binding adapter to set background colour when the colour is coming from api as hex code?

Question

Background colour is coming from API in this form FFF9E6.I am using data binding.I am not able to understand how I can set it as background colour. I believe binding adapter would work but not sure how to write it. How can I write binding adapter for the same?

Answer 1

This code worked in my case.

@BindingAdapter("android:backgroundColor")
fun ViewGroup.setBackground(backgroundColor: String) {

val color: Int = try {
    Color.parseColor(background)
} catch (e: Exception) {
    Color.parseColor("#$background")
}
setBackgroundColor(color)
}

Answer 2

I ran into this same problem a few months back. what I did was stored the data coming from API to one POJO class. Then in an XML file using that POJO class member as data binding variable. i.e.

<TextView
            android:layout_width="0dp"
            android:layout_height="60dp"
            android:layout_margin="@dimen/_8dp"
            android:layout_weight="1"
            android:gravity="center"
            android:padding="@dimen/_8dp"
            app:color="@{item.color}" />

and it's binding adapter

@BindingAdapter("bind:color")
public static void setStatus(TextView textView, String color) {

}
