为什么onCreateView中的WebView代码无法访问？

Question

Unreachable code webview kotlin.

I already looked for several solutions but nothing works, someone could help me.

class ForumFragment : Fragment() {

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {
        return inflater.inflate(R.layout.fragment_forum, container, false)

        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl("https://www.google.com/");
        webView.clearView();
        webView.measure(100, 100);
        webView.getSettings().setUseWideViewPort(true)
        webView.getSettings().setLoadWithOverviewMode(true);
    }
}

That's because your function is returning before executing the lines below. When the function "returns" it's basically doing an exit to the outer scope.

This should do:

class ForumFragment : Fragment() {

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl("https://www.google.com/");
        webView.clearView();
        webView.measure(100, 100);
        webView.getSettings().setUseWideViewPort(true)
        webView.getSettings().setLoadWithOverviewMode(true);

        return inflater.inflate(R.layout.fragment_forum, container, false)
    }
}
