Android WebView open external link in browser

Question

I'm learning programming on android , does anyone know how I could do to open links to the different default browser on my domain?

If someone would be kind enough to explain to me how I could also create a menu for the page refresh and an alert indicating that the missing internet connection.

Answer 1

If You open HTML or URL in Deafulat Browser Used TextView

For HTML

String value = "Visit my blog http://www.maxartists.com\\">mysite View myactivity callback";

String value = "<html>Visit my blog <a href=\"http://www.maxartists.com\">mysite</a> View <a href=\"sherif-activity://myactivity?author=sherif&nick=king\">myactivity</a> callback</html>";
    TextView text = (TextView) findViewById(R.id.text);
        text.setText(Html.fromHtml(value));
    text.setMovementMethod(LinkMovementMethod.getInstance());

For URL

tv.setText("www.google.com  www.facebook.com  www.yahoo.com");
tv.setMovementMethod(LinkMovementMethod.getInstance());;
tv.setText(Html.fromHtml(tv.getText().toString()));
Linkify.addLinks(tv, Linkify.WEB_URLS);

Answer 2

All links other than "String url" will be opened on the browsers default, not in WebApp. – Davide Infsercom just now edit
