can help me, guys? here, codes..

detalhesfragment.java

package com.example.waitersoriginal; import android.app.fragment; import android.content.dialoginterface; import android.content.dialoginterface.onclicklistener; import android.os.bundle; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.absolutelayout; import android.widget.button; import android.widget.textview; public class detalhesfragment extends fragment implements onclicklistener{ textview nomeentrada,descrentrada,valorentrada,nmarm,dsarm,vlarm; string txtnome, txtdescr; view view; @override public view oncreateview(layoutinflater inflater,viewgroup container, bundle savedinstancestate) { view = inflater.inflate(r.layout.detalhes_fragment, container, false); button mbutton = (button) view.findviewbyid(r.id.button1); nomeentrada= (textview) view.findviewbyid(r.id.textview1); descrentrada= (textview)view.findviewbyid(r.id.textview2); valorentrada= (textview)view.findviewbyid(r.id.textview3); mbutton.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { // todo auto-generated method stub switch (v.getid()) { case r.id.button1: pedidosfragment array = (pedidosfragment)getfragmentmanager().findfragmentbyid(r.id.fragment3); array.criaarray(txtnome,txtdescr); break; } } } ); homecoming view; } public void change(string txt, string txt1){ nomeentrada.settext(txt); descrentrada.settext(txt1); txtnome = txt; txtdescr = txt1; //valorentrada.settext(txt2); } @override public void onclick(dialoginterface dialog, int which) { // todo auto-generated method stub } }

pedidosfragment.java

package com.example.waitersoriginal; import java.util.arraylist; import java.util.arrays; import java.util.hashmap; import android.app.fragment; import android.os.bundle; import android.app.listfragment; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.adapterview; import android.widget.arrayadapter; import android.widget.baseadapter; import android.widget.listadapter; import android.widget.listview; import android.widget.simpleadapter; import android.widget.adapterview.onitemclicklistener; public class pedidosfragment extends listfragment{ private arraylist<hashmap<string, string>> listapedidos; private static final string tag_nm = "nome"; private static final string tag_ds = "descr"; public pedidosfragment(){} @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { homecoming inflater.inflate(r.layout.pedidos_fragment, container, false); } void criaarray(string nomeprod, string descrprod) { listapedidos = new arraylist<hashmap<string, string>>(); hashmap<string, string> map3 = new hashmap<string, string>(); listadapter adapter2 = new simpleadapter(getactivity(), listapedidos, r.layout.list_item, new string[] { tag_nm, tag_ds}, new int[] { r.id.name, r.id.pid}); setlistadapter(adapter2); map3.put(tag_nm, nomeprod); map3.put(tag_ds, descrprod); listapedidos.add(map3); ((baseadapter) adapter2).notifydatasetchanged(); } }

thank you..!

each time overriding adapter , creating new 1 each time, newest item.

try (assuming both fragments in memory) :

public class pedidosfragment extends listfragment{ private arraylist<hashmap<string, string>> listapedidos; private static final string tag_nm = "nome"; private static final string tag_ds = "descr"; public pedidosfragment(){} @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { listapedidos = new arraylist<hashmap<string, string>>(); listadapter adapter2 = new simpleadapter(getactivity(), listapedidos, r.layout.list_item, new string[] { tag_nm, tag_ds}, new int[] { r.id.name, r.id.pid}); setlistadapter(adapter2); homecoming inflater.inflate(r.layout.pedidos_fragment, container, false); } void criaarray(string nomeprod, string descrprod) { hashmap<string, string> map3 = new hashmap<string, string>(); map3.put(tag_nm, nomeprod); map3.put(tag_ds, descrprod); listapedidos.add(map3); ((baseadapter) adapter2).notifydatasetchanged(); } }

also, avoid using constructors fragments, instead utilize bundles

hope helps
