I know there must be something wrong in my "DetailsActivity.kt",

especially on this line :

 prodBundle?.getString("btnURLMainTabFragment1").let {
          btn_wvURL.setOnClickListener {
              val gotoWebView = Intent(this@DetailsActivity, WebViewActivity::class.java)
              gotoWebView.putExtra("btnURLMainTabFragment1", gotoWebView)
              startActivity(gotoWebView)
          }

How to solve it?

I hope someone can solve this case. And thanks for taking your time.

CodePudding user response：

Here you are sending the intent as an extra to the intent itself:

val gotoWebView = Intent(this@DetailsActivity, WebViewActivity::class.java)
>>> gotoWebView.putExtra("btnURLMainTabFragment1", gotoWebView)

You can try:

prodBundle?.getString("btnURLMainTabFragment1")?.let { url->
          btn_wvURL.setOnClickListener {
              val gotoWebView = Intent(this@DetailsActivity, WebViewActivity::class.java)
              gotoWebView.putExtra("btnURLMainTabFragment1", url)
              startActivity(gotoWebView)
          }

This should work.
