-

i doing application tabhost formate, tab displaying default color, there possibility change default color our own color.? got ideas google, 

tabhost.setontabchangedlistener(new ontabchangelistener(){     @override     public void ontabchanged(string tabid) {         // todo auto-generated method stub          for(int i=0;i<tabhost.gettabwidget().getchildcount();i++)             {                tabhost.gettabwidget().getchildat(i).setbackgroundcolor(r.color.transparent); //unselected             }             tabhost.gettabwidget().getchildat(tabhost.getcurrenttab()).setbackgroundcolor(color.parsecolor("#000011")); // selected     }

whenever doing getting force close error. if having idea of changing background color, pls guide me.

you need first change default appearence

for(int i=0;i<tabhost.gettabwidget().getchildcount();i++)     {     if (i == 0) tabhost.gettabwidget().getchildat(i).setbackgroundcolor(color.parsecolor("#ffffff"));      else tabhost.gettabwidget().getchildat(i).setbackgroundcolor(color.parsecolor("#7392b5"));     }

before dealing ontabchanged event

tabhost.setontabchangedlistener(new ontabchangelistener(){ @override public void ontabchanged(string tabid) {     // todo auto-generated method stub      for(int i=0;i<tabhost.gettabwidget().getchildcount();i++)         {            tabhost.gettabwidget().getchildat(i).setbackgroundcolor(color.parsecolor("#7392b5")); //unselected         }         tabhost.gettabwidget().getchildat(tabhost.getcurrenttab()).setbackgroundcolor(color.parsecolor("#ffffff")); // selected } });
