If you are using it in an static AsyncTask, or any other class, you can pass the activity as a parameter to a method or constructor, for example:

activity onCreate:

//Pass activity variable (this)
new Main2Activity.MyTask().execute(this);

class inside activity:

private static class MyTask extends AsyncTask {

        Main2Activity activity;

        @Override
        protected String doInBackground(Object... params) {
            activity = (Main2Activity)params[0];
            ....
        }

        @Override
        protected void onPostExecute(String str) {
            // Use parameter activity passed to class
            WebView webView = activity.findViewById(R.id.web_view);
            webView.loadData(str, "text/html; charset=UTF-8", null);
        }
