android - 如何显示进度对话框并在项目单击时关闭

Question

 override fun itemclick(position: Int) {
        binding.progressbar.visibility=View.VISIBLE
        binding?.barcode?.setImageBitmap(exchngeViewModel.getQrImageBitmap(qrCodeData[position], this!!.activity!!))
        showDetail(position)
        binding.progressbar.visibility=View.GONE
    }    

fun getQrImageBitmap(data: String, context: Context): Bitmap? {
        bitMap = AppUtils.TextToImageEncode(data, context, bus) 
        return this!!.bitMap
    }

这是我的代码，我想dialog在项目点击上显示进度，它应该在那个时候关闭，直到 getQrImageBitmapshowDetail 功能完成，但我没有工作，请建议我如何实现这一点，如何在项目点击上显示和隐藏细节。谢谢！

Answer 1

showDetail()在方法内添加进度条

  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
}
