i new android. create apps followed tutorial. create restaurant info page. when type name , address , types , should show details , instead of shows in emulator

com.example.lunchlist.restaurant@40ad8sd com.example.lunchlist.restaurant@40fhyu5

here xml code:

activity_lunch_list.xml

    <?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:stretchcolumns="1" > <tablelayout android:id="@+id/details" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignparentbottom="true" android:stretchcolumns="1" >  <tablerow >       <textview     android:text="@string/namee" /> <edittext  android:id="@+id/name"  android:ems="10"  android:inputtype="text"></edittext>  </tablerow> <tablerow>      <textview     android:text="@string/addresss" />      <edittext     android:id="@+id/addr"     android:inputtype="text"></edittext>  </tablerow>  <tablerow >   <textview android:text="@string/types"/>      <radiogroup android:id="@+id/type">       <radiobutton android:id="@+id/take_out"                android:text="@string/take"   />            <radiobutton android:id="@+id/sit_down"                android:text="@string/sit" />        <radiobutton android:id="@+id/delivery"                android:text="@string/deliveryy" />      </radiogroup>  </tablerow>     <button     android:id="@+id/button1"     android:text="@string/save" />    </tablelayout>    <listview android:id="@+id/restaurants" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignparenttop="true" android:layout_above="@id/details" />  </relativelayout>

here java code:

lunchlist.java

package com.example.lunchlist;  import java.util.list; import java.util.arraylist; import android.os.bundle; import android.app.activity; //import android.view.menu; import android.widget.arrayadapter; import android.widget.button; import android.widget.edittext; import android.widget.listview; import android.view.view; //import android.widget.edittext; //import android.widget.radiobutton; import android.widget.radiogroup; //import android.widget.toast;   public class lunchlist extends activity { list<restaurant> model=new arraylist<restaurant>(); arrayadapter<restaurant> adapter=null; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_lunch_list); button save=(button)findviewbyid(r.id.button1); save.setonclicklistener(onsave); listview list=(listview)findviewbyid(r.id.restaurants); adapter=new arrayadapter<restaurant>(this, android.r.layout.simple_list_item_1, model); list.setadapter(adapter); } private view.onclicklistener onsave=new view.onclicklistener() { public void onclick(view v) { restaurant r=new restaurant(); edittext name=(edittext)findviewbyid(r.id.name); edittext address=(edittext)findviewbyid(r.id.addr); r.setname(name.gettext().tostring()); r.setaddress(address.gettext().tostring()); radiogroup types=(radiogroup)findviewbyid(r.id.type); switch (types.getcheckedradiobuttonid()) { case r.id.sit_down: r.settype("sit_down"); break; case r.id.take_out: r.settype("take_out"); break; case r.id.delivery: r.settype("delivery"); break; } adapter.add(r); }; }; }

here restaurant.java page:

package com.example.lunchlist; public class restaurant  {     private string name="";     private string address="";     private string type="";     public string getname() {     return(name);     }     public void setname(string name) {     this.name=name;     }     public string getaddress() {     return(address);     }     public void setaddress(string address) {     this.address=address;     }      public string gettype() {     return(type);     }      public void settype(string type) {         this.type=type;     }    }

any appreciated

its problem adapter. passing restaurant object adapter should string set text in textview.

and item should not added adapter instead must added arraylist , must notify data change adapter calling adapter.notifydatasetchange()

i.e., lunchlist class should follows

public class lunchlist extends activity {     list<string> model = new arraylist<string>();     arrayadapter<string> adapter = null;      @override     public void oncreate(bundle savedinstancestate)     {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_lunch_list);         button save = (button) findviewbyid(r.id.button1);         save.setonclicklistener(onsave);         listview list = (listview) findviewbyid(r.id.restaurants);         adapter = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, model);         list.setadapter(adapter);     }      private view.onclicklistener onsave = new view.onclicklistener()     {         @override         public void onclick(view v)         {             restaurant r = new restaurant();             edittext name = (edittext) findviewbyid(r.id.name);             edittext address = (edittext) findviewbyid(r.id.addr);             r.setname(name.gettext().tostring());             r.setaddress(address.gettext().tostring());             radiogroup types = (radiogroup) findviewbyid(r.id.type);             switch ( types.getcheckedradiobuttonid() )             {                 case r.id.sit_down:                     r.settype("sit_down");                     break;                 case r.id.take_out:                     r.settype("take_out");                     break;                 case r.id.delivery:                     r.settype("delivery");                     break;             }             model.add(r.gettype());             adapter.notifydatasetchanged();         };     }; }

note : if want display 3 (name, address , type) in listview, use custom listview

android custom listview image , text

customizing android listview items custom arrayadapter

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
