Answer 1

您可以创建自己的Web视图活动，并在选择导航项时启动活动，如下所示。

  Intent startWebViewIntent=new Intent(this,SurahWebviewActivity.class);
   startWebViewIntent.putExtra("PrayerTime",1);
   startActivity(startWebViewIntent);

但是在您的代码中，您可以创建一个方法来使用链接加载Web视图，并在选择导航项时调用该方法。它可能类似于跟随。

 public boolean onNavigationItemSelected(MenuItem item)
    {
        // Handle navigation view item clicks here.

        int id = item.getItemId();

        if (id == R.id.classmaster)
        {
            URI uri=Uri.parse("http://app.schoolbios.com/main#/class_master"));
            populateWebView(uri);
        }
}

private void populateWebView(URI uri){
    thisWebView.loadUrl(uri);
}
