java - How can I connect to a specific wifi network? -

i have devlope project list out wifi connection available near device.now, want connect 1 specific network connection. can do? have got networks in listview. if example available post comment link.

private void getwifinetworkslist() {     intentfilter filter = new intentfilter();     filter.addaction(wifimanager.scan_results_available_action);     final wifimanager wifimanager = (wifimanager) getapplicationcontext()             .getsystemservice(context.wifi_service);     ;     registerreceiver(new broadcastreceiver() {          @suppresslint("usevalueof")         @override         public void onreceive(context context, intent intent) {             sb = new stringbuilder();             scanlist = wifimanager.getscanresults();             sb.append("\n  number of wifi connections :" + " "                     + scanlist.size() + "\n\n");             adapter = new arrayadapter<string>(draginoactivity.this,                     android.r.layout.simple_list_item_1, list);             adapter.clear();             (int = 0; < scanlist.size(); i++) {                  listwifidevice.setadapter(adapter);                  // list.add(new integer(i + 1).tostring() + ".

 private void setnetworkslist() {     networkslist = (listview) findviewbyid(r.id.networklist);     networkslist.setonitemclicklistener(new onitemclicklistener() {         @override         public void onitemclick(adapterview<?> parent, view view, final int position,                                 long id) {             final int chosenposition = position;             wifiitem wifiitem = new wifiitem();             wifiitem = (wifiitem) parent.getitematposition(position);             networkssid = wifiitem.getssid();             networkpass = "";             showpassworddialog(connectactivity.this);             setpasswordlistener(new passwordtypedlistener() {                  @override                 public void onpasswordtyped() {                     connecthelper = new connecthelper();                     if(scanresult.get(chosenposition).capabilities.contains("wep")) {                         connecthelper.setupconnection(networkssid, networkpass, "wep");                     }                     //jezeli siec wpa                     else if(scanresult.get(chosenposition).capabilities.contains("wpa")) {                         connecthelper.setupconnection(networkssid, networkpass, "wpa");                     }                      //inne przypadki (open network)                     else {                         connecthelper.setupconnection(networkssid, networkpass, "else");                     }                      wifimanager.addnetwork(connecthelper.getconfiguration());                      list<wificonfiguration> list = wifimanager.getconfigurednetworks();                     for( wificonfiguration : list ) {                         if(i.ssid != null && i.ssid.equals("\"" + networkssid + "\"")) {                             wifimanager.disconnect();                             wifimanager.enablenetwork(i.networkid, true);                             if(wifimanager.reconnect()) {                                 for(int j=0;j<listwifi.size();j++){                                     listwifi.get(j).setconnected(false);                                 }                                 runnablecounter=0;                                 handler.postdelayed(ifconnected,1000);                             }                             break;                         }                     }                 }              });          }      }); } 

and dialog

 private void showpassworddialog(context context) {     final edittext input = new edittext(context);     input.setsingleline();     alertdialog.builder alert = new alertdialog.builder(context);     alert.settitle("password");     alert.setview(input);     alert.setpositivebutton("confirm", new dialoginterface.onclicklistener() {         @override         public void onclick(dialoginterface dialog, int which) {             networkpass = input.gettext().tostring();             if(connectactivity.this.passwordlistener != null)                 connectactivity.this.passwordlistener.onpasswordtyped();         }     });     alert.setnegativebutton("cancel", new dialoginterface.onclicklistener() {         @override         public void onclick(dialoginterface dialog, int which) {         }     });     alert.show();  } 

and in oncreate skip creating wifiitems , store ssids

    arraylist<wifiitem> listwifi = new arraylist<wifiitem>();     wifimanager.startscan();     scanresult = wifimanager.getscanresults();             for(scanresult sc : scanresult) {         wifiitem wifiitem = new wifiitem();         wifiitem.setssid(sc.ssid);         wifiitem.setbssid(sc.bssid);                    listwifi.add(wifiitem);     }
