package com.idea.remote; import android.view.view.onclicklistener; import java.util.list; import com.idea.*; import android.annotation.suppresslint; import android.app.activity; import android.content.context; import android.content.intent; import android.util.log; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.arrayadapter; import android.widget.imageview; import android.widget.textview; import android.widget.toast; public class userpostslistviewadapter extends arrayadapter<userpostsitemform> { context context; list<userpostsitemform> items; public userpostslistviewadapter(context context, int resourceid, list<userpostsitemform> items) { super(context, resourceid, items); this.context = context; this.items=items; } /*private view holder class*/ private class viewholder { imageview imageview; textview txtusername; textview txtdesc; textview sweetno; textview idealcount; textview userid; textview postid; imageview replyid; imageview addfriend; imageview sweetbutton; imageview imageview4; imageview imageview2; } @suppresslint("showtoast") public view getview( int position, view convertview, viewgroup parent) { viewholder holder = null; userpostsitemform rowitem = getitem(position); layoutinflater minflater = (layoutinflater) context .getsystemservice(activity.layout_inflater_service); if (convertview == null) { convertview = minflater.inflate(r.layout.user_posts, null); holder = new viewholder(); holder.txtdesc = (textview) convertview.findviewbyid(r.id.desc); holder.txtusername = (textview) convertview.findviewbyid(r.id.username); holder.imageview = (imageview) convertview.findviewbyid(r.id.imageview1); holder.sweetno = (textview) convertview.findviewbyid(r.id.sweetno); holder.idealcount = (textview) convertview.findviewbyid(r.id.idealcount); holder.sweetbutton= (imageview) convertview.findviewbyid(r.id.sweetbutton); holder.imageview4= (imageview) convertview.findviewbyid(r.id.imageview4); holder.imageview2= (imageview) convertview.findviewbyid(r.id.imageview2); final string userid1=items.get(position).getuserid(); imageview addfriend1 = (imageview) convertview.findviewbyid(r.id.imageview5); holder.addfriend=addfriend1; holder.addfriend.settag(integer.parseint(items.get(position).getuserid())); holder.addfriend.settag(userid1); //for passing list item index final string addfriendtag=(string) holder.addfriend.gettag(); holder.addfriend.setonclicklistener(new onclicklistener() { @override public void onclick(view arg0) { toast toast = toast.maketext(context, " "+ addfriendtag,toast.length_short); toast.show(); } }); convertview.settag(holder); } else holder = (viewholder) convertview.gettag(); //for sweet button holder.sweetbutton.settag(integer.parseint(items.get(position).getpostid())); final int sweetbuttontag= (integer) holder.sweetbutton.gettag(); holder.sweetbutton.setonclicklistener(new onclicklistener() { @override public void onclick(view arg0) { toast toast = toast.maketext(context, "sweetbutton "+ sweetbuttontag,toast.length_short); toast.show(); string userid="18"; voteupdownwallpost wallpost2=new voteupdownwallpost(sweetbuttontag,userid,context,"addwallpostvoteup"); wallpost2.sendtopost(); } }); //for ideal button holder.imageview4.settag(integer.parseint(items.get(position).getpostid())); final int idealbuttontag= (integer) holder.imageview4.gettag(); holder.imageview4.setonclicklistener(new onclicklistener() { @override public void onclick(view arg0) { toast toast = toast.maketext(context, "ideal button "+ idealbuttontag,toast.length_short); toast.show(); string userid="18"; voteupdownwallpost wallpost2=new voteupdownwallpost(idealbuttontag,userid,context,"addwallpostvotedown"); string status=wallpost2.sendtopost(); if(status=="true"){ // holder.sweetno.settext(rowitem.getsweetno()+1); } } }); //reply button holder.imageview2.settag(integer.parseint(items.get(position).getuserid())); final int replybuttontag= (integer) holder.imageview2.gettag(); holder.imageview2.setonclicklistener(new onclicklistener() { @override public void onclick(view arg0) { toast toast = toast.maketext(context, "reply "+ replybuttontag,toast.length_short); toast.show(); string userid="18"; //voteupdownwallpost wallpost2=new voteupdownwallpost(replybuttontag,userid,context,"addwallpostvotedown"); // string status=wallpost2.sendtopost(); /// if(status=="true"){ // holder.sweetno.settext(rowitem.getsweetno()+1); // } } }); holder.sweetbutton.settag(rowitem.getpostid()); holder.txtdesc.settext(rowitem.getdesc()); holder.txtusername.settext(rowitem.getusername()); holder.imageview.setimagebitmap(rowitem.getimageid()); holder.sweetno.settext(rowitem.getsweetno()); holder.idealcount.settext(rowitem.getidealcount()); return convertview; } } and 1 more thing. how change added text , sweet button count.
and onclick post button in activity class:-
postbutton.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { edittext data=(edittext) findviewbyid(r.id.edittext02); string wallpost=data.gettext().tostring(); string userid="18"; senduserwallpost wallpost2=new senduserwallpost(wallpost,userid,context); string status= wallpost2.sendtopost(); // ad.setmessage(status); // ad.show(); intent callmenuclass = new intent(blackboardlayout.this, blackboardlayout.class); startactivity(callmenuclass); //filllistpost(); } });
you add new post this:
post post = new post(); userpostslistviewadapter.add(post); userpostslistviewadapter.notifydatasetchanged();
