当颜色来自api作为十六进制代码时，如何编写绑定适配器来设置背景颜色？

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

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. ie

<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) {

}

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)
}
