如何将 Android ViewBinding 用于从现有布局膨胀的自定义视图

Question

I see there is ViewBinding support for Activity and Fragment. But how about custom view?

My custom view likes this:

class MyView @JvmOverloads constructor(
        context: Context,
        attrs: AttributeSet? = null,
        defStyleAttr: Int = 0,
        defStyleRes: Int = 0
) : LinearLayout(context, attrs, defStyleAttr, defStyleRes) {

    init {
        inflate(context, R.layout.my_view, this)
    }
}

I try to create ViewBinding but it doesn't work.

    private val binding: MyViewBinding

    init {
        inflate(context, R.layout.my_view, this)
        binding = MyViewBinding.inflate(LayoutInflater.from(context))
    }

Do you have any solution for ViewBinding with custom view?

Answer 1

you try replace

   init {
        inflate(context, R.layout.my_view, this)
        binding = MyViewBinding.inflate(LayoutInflater.from(context))
    }

with

   init {
        binding = MyViewBinding.inflate(LayoutInflater.from(context),this, false)
    }
