[Custom ProgressBar] progressBar + alertDialog => background : X, blur : O

ReadMe.md

기본 progressBar의 뒷 배경에 blur 처리를 위해 AlertDialog를 사용.

progressBar를 module화 함으로 여러 곳에서 다양하게 사용하기 위해 만듬.

// progress 시작 시 val progressBar = customProgressBar(context, layoutinflater

// 종료 시 progressBar.dismiss()

customProgressBar.kt

fun customProgressBar(context: Context, layoutInflater: LayoutInflater): AlertDialog {
    val binding = DialogProgressbarBinding.inflate(layoutInflater)

    return AlertDialog.Builder(context)
        .setCancelable(false)
        .setView(binding.root)
        .show().apply {
            // 뒷 배경 blur 처리
            this.window!!.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
        }
}
