webview - Adding dynamic web views in android -

i going through various links on topic. haven't found useful in case. want create web view in android dynamically. add nothing onto xml layout file. want 2 things in particular: 1. want set size of web view custom width , height , set @ bottom of layout. 2. once page loads in web view. on click on web view should resize , go full screen(which means fill_parent on width , height web view in parent layout).

my current code looks below not work particularly full screen not fit content screen:

public class mainactivity extends activity {       relativelayout layout;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          layout=(relativelayout)findviewbyid(r.id.test);          final webview web = new webview(this);          //web.setid(1);         web.getsettings().setjavascriptenabled(true);         web.loaddata("<script type=\"text/javascript\" src=\"http://www..myurl.com/myfolder/banner.php\"></script>", null, null);          layout.addview(web, new layoutparams(300,100));           web.setontouchlistener(new ontouchlistener() {              @override             public boolean ontouch(view v, motionevent event) {                 // todo auto-generated method stub                 web.setlayoutparams(new layoutparams(layoutparams.match_parent,layoutparams.match_parent));                 return false;             }         });      }        @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }  } 

if understand problem correctly, may want consider following approach.

first, declare , initialize (parent) relative layout, parameters , set content view (delete setcontentview(r.layout.activity_main);).

    final relativelayout layout = new relativelayout(this);      final relativelayout.layoutparams params = new relativelayout.layoutparams(             getwindowmanager().getdefaultdisplay().getwidth(),             getwindowmanager().getdefaultdisplay().getheight());      layout.setlayoutparams(params);      setcontentview(layout); 

then, initialize web view , parameters, , add "bottom rule" parameters.

    final webview web = new webview(this);      web.getsettings().setjavascriptenabled(true);     web.loaddata(             "<script type=\"text/javascript\" src=\"http://www..myurl.com/myfolder/banner.php\"></script>",             null, null);      relativelayout.layoutparams webviewparams = new relativelayout.layoutparams(             300, 100);     webviewparams.addrule(relativelayout.align_parent_bottom); 

finally, add web view (parent) relative layout , add listener.

    layout.addview(web, webviewparams);      web.setontouchlistener(new ontouchlistener() {          public boolean ontouch(view arg0, motionevent arg1) {             web.setlayoutparams(params);             return false;         }     }); 

hope needed.

cheers!
