yes because `getQrImageBitmap` and `showDetail` executed means it will hide. — Ramesh sambu, Jan 02 '18 at 04:54

Add Prorgressbar inside showDetail() method

  fun showDetail(position: Int) {
    SharedPreferenceUtils.setExchangePagePostion(this!!.activity!!, position)
    binding?.textHeader?.text = exchangeData[position]
    binding?.backButton?.visibility = View.VISIBLE
    binding?.recyclerView?.visibility = View.GONE
    binding?.barcode?.visibility = View.VISIBLE
    binding?.header1?.setBackgroundResource(R.color.colorOrangeGray)
    binding?.exchangeButton?.visibility = View.VISIBLE


    binding.progressbar.visibility=View.GONE
}
