Text on Progressbar

Question

I’m a beginner in Android, and I’m with a doubt here that for many can be simple, but for me it’s kind of complicated to solve. Ai goes:

I have an app that loads a webview, I put a progressiBar to know if it is opening or not, but I wanted to add a text above or below the written progressibar:

"Wait Carrregando the system"

How do I do that?

Below follows the code of Mainactivity.java and Mainactivity.xml.

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView wv = (WebView) findViewById(R.id.webView);
        wv.setWebViewClient(new WebViewClient());
        WebSettings ws= wv.getSettings();
        ws.setJavaScriptEnabled(true);
        ws.setSupportZoom(false);
        //news implementation

        wv.setWebChromeClient(new WebChromeClient());

        //Barra de Progresso / Carregando
        final ProgressBar Pbar;
        Pbar = (ProgressBar) findViewById(R.id.progressBar);


        wv.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress) {
                if (progress < 100 && Pbar.getVisibility() == ProgressBar.GONE) {
                    Pbar.setVisibility(ProgressBar.VISIBLE);
                }
                Pbar.setProgress(progress);
                if (progress == 100) {
                    Pbar.setVisibility(ProgressBar.GONE);
                }
            }

Answer 1

I see two solutions:

1) You can use a ProgressDialog in this upload. This way you will have a text window above the webview. It is very intuitive for the user.

2) If you wish to do without the ProgressDialog, can use a composition of layout components (RelativeLayout or LinearLayout) to position a TextView above or beside the ProgressBar.

I hope I’ve helped!
