Can anyone help me :/ I'm really appreciate your time and help for consideration for solving my error. Thanks in Advance!

Answer 1

You have a custom view referenced in your layout XML, and the custom view doesn't have the required public constructor that takes in Context,AttributeSet arguments.

Answer 2

If you arrived at this post but are using Kotlin, annotate your constructor with @JvmOverloads.

Doc: Kotlin - Overloads Generation

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

Answer 3

An improvement to @Shazbot's answer for Kotlin. Add these constructors:

class CustomView : View {

    constructor(context: Context) : super(context)

    constructor(context: Context, attrs: AttributeSet) : super(context, attrs)

    constructor(context: Context, attrs: AttributeSet, defStyle: Int) : super(context, attrs, defStyle)

}

When you need init:

class CustomView : View {

    constructor(context: Context) : super(context) {
        init(null, 0)
    }

    constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {
        init(attrs, 0)
    }

    constructor(context: Context, attrs: AttributeSet, defStyle: Int) : super(context, attrs, defStyle) {
        init(attrs, defStyle)
    }

    private fun init(attrs: AttributeSet?, defStyle: Int) {
        // do something
    }
