android - How to make a ListActivity with custom List Item with nested clickable Button -
now have activity, shows list of usernames. ok works. need show custom listview item username @ left , button @ right (this button call programatically given phone number).
i know have custom adapter, skills low. , dont know how use when have done.
can me making easy custom adapter manage listitem 1 textview , 1 button , giving me code use custom adapter?
the adapter should able use new list_item2.xml:
<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <textview android:id="@+id/friendname" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentleft="true" android:padding="10dp" android:textsize="16sp"/> <button android:id="@+id/callbutton" android:layout_alignbaseline="@id/friendname" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="call" android:width="100px" android:layout_alignparentright="true"/> </relativelayout> this code use now:
list_item.xml:
xml version="1.0" encoding="utf-8"?> <textview xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:textsize="16sp" > </textview> this listactivity class:
public class allactivity extends listactivity { remoteconnection con; //conexion remota //private mydbadapter mdbhelper; private list<friend> friends; //lista de amigos private list<string> usernames; //lista de usernames de amigos, para rellenar el listview //private list<permission> permissions; //para almacenar la config local de mi app, mostrarme o no en el mapa... static sharedpreferences settings; static sharedpreferences.editor configeditor; public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); settings=preferencemanager.getdefaultsharedpreferences(this.getapplicationcontext()); configeditor = settings.edit(); friends = new arraylist<friend>(); usernames = new arraylist<string>(); //mdbhelper=myapplication.getdatabaseadapter(); con = new remoteconnection(); actualizar(); } protected void onactivityresult(int requestcode, int resultcode, intent data) { if (resultcode == 1) { setresult(1); finish(); } } public void onresume() { super.onresume(); actualizar(); } public void actualizar() { //friends = con.retrievefriends(settings.getstring("login","")); friends = myapplication.getdatabaseadapter().retrieveallfriends(); usernames.clear(); (int i=0;i<friends.size();i++) //for (int i=0;i<permissions.size();i++) { usernames.add(i,friends.get(i).getfullname()); //if (friends.get(i).getlastposition()!=null) // usernames.add(i,friends.get(i).getlastposition().getpositiontimeformated()); } setlistadapter(new arrayadapter<string>(this, r.layout.list_item3, usernames)); listview lv = getlistview(); lv.settextfilterenabled(true); lv.setonitemclicklistener(new onitemclicklistener() { public void onitemclick(adapterview<?> parent, view view, int position, long id) { bundle bundle = new bundle(); //bundle letter bundle.putstring ("user", friends.get(position).getfullname()); //arg1 keyword of txt, arg2 txt bundle.putstring ("email", friends.get(position).getemail()); bundle.putstring ("permission", friends.get(position).getpermission()); intent i=null; if (friends.get(position).getpermission().equals("total")) = new intent (allactivity.this, locate.class); else if (friends.get(position).getpermission().equals("perhours")) = new intent (allactivity.this, locateperhours.class); else = new intent (allactivity.this, locateperdays.class); i.putextras(bundle); startactivity(i); //startactivityforresult(i, 0); } }); } }
i edited code compatible yours
i write code modification achieve want... call initialactivity yo yhe listactivity , populate list string array (populate them not problem) so, maybe other things you...

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <textview android:id="@+id/friendname" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentleft="true" android:padding="10dp" android:textsize="16sp"/> <button android:id="@+id/callbutton" android:layout_alignbaseline="@id/friendname" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="call" android:width="100px" android:layout_alignparentright="true"/> </relativelayout> i tested in device , works, delete dataholder class.
the other things bundle map, intent, commented because think not problem.
cheers.
