<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginHorizontal="@dimen/button_horizontal"
        android:layout_marginVertical="@dimen/button_vertical"
        android:divider="@drawable/divider"
        android:orientation="horizontal"
        android:showDividers="middle"

            android:layout_height="wrap_content" />

    </LinearLayout>

</androidx.constraintlayout.widget.ConstraintLayout>

XButton.kt


class XButton : AppCompatButton {
    constructor(context: Context) : super(context) {
        init(
            context = context,
            attrs = null,
        )
    }

    constructor(
        context: Context,
        attrs: AttributeSet?,
    ) : super(
        context,
        attrs,
    ) {
        init(
            context = context,
            attrs = attrs,
        )
    }

    constructor(
        context: Context,
        attrs: AttributeSet?,
        defStyleAttr: Int,
    ) : super(
        context,
        attrs,
        defStyleAttr,
    ) {
        init(
            context = context,
            attrs = attrs,
        )
    }

    private lateinit var attributes: TypedArray

    private fun init(
        context: Context,
        attrs: AttributeSet?,
    ) {
        setAttributes(
            context = context,
            attrs = attrs,
        )
    }

    private fun setAttributes(
        context: Context,
        attrs: AttributeSet?,
    ) {
        attributes = context.obtainStyledAttributes(
            attrs,
            R.styleable.XButton,
        )
    }
}

I tried to inflate button.xml to XButton.kt but I can't..

Before, I implement custom button by extends LinearLayout.

Of course I can use my custom views in button.xml when I extends LinearLayout.

But I have to implement this button by extends AppCompatButton.

I can't use findViewById... because this return null object also binding not working.

I want how inflate my button.xml to XButton.kt!!

How to implement my custom button by extends AppCompatButton..?

Try to use view binding <- not working

Try to use findViewById <- return null object
