Findviewbyid (R.ID.EDITTEXT1); TV= (TextView) This. Findviewbyid (r.id.tv); CT="aaa<font color=\ "red\" >aaa</font>"; Addpic= (Button) This. Findviewbyid (R.id.addpic); Addpic.setonclicklistener (NewOnclicklistener () {@Override Public voidOnClick (View arg0) {//TODO auto-generated Method Stubct+=""+r.drawable.icon+"\ "/>";            Refreshview ();              }                    });                    Refreshview (); }    Private voidRefreshview () {Et.settext (html.fromhtml (Ct,imagegetter,NULL)); Tv.settext (html.fromhtml (Ct,imagegetter,NULL)); } imagegetter Imagegetter=NewImagegetter () {@Override Publicdrawable getdrawable (String source) {intID =integer.parseint (source); Drawable D=getresources (). getdrawable (ID); D.setbounds (0,0, D.getintrinsicwidth (), D. Getintrinsicheight ()); returnD;  }      };
