activity java code

package test.application;

     public class mainactivity extends activity {  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);       hashmap<string, string> hashmapone = new hashmap<string, string>();     hashmapone.put("keyone", "export");     hashmapone.put("key_two", "a");      hashmap<string, string> hashmaptwo = new hashmap<string, string>();     hashmaptwo.put("keyone", "import");     hashmaptwo.put("key_two", "b");      hashmap<string, string> hashmapthree = new hashmap<string, string>();     hashmapthree.put("keyone", "import");     hashmapthree.put("key_two", "c");       hashmap<string, string> hashmapfour = new hashmap<string, string>();     hashmapfour.put("keyone", "export");     hashmapfour.put("key_two", "c");      arraylist<hashmap<string, string>> hashlist = new arraylist<hashmap<string, string>>();      hashlist.add(hashmapone);     hashlist.add(hashmaptwo);     hashlist.add(hashmapthree);     hashlist.add(hashmapfour);      setcontentview(r.layout.activity_main);     simpleadapter simpleadapter = new simpleadapter(mainactivity.this, hashlist,             r.layout.list_test, new string[] { "keyone",                     "key_two" }, new int[] { r.id.txtone,                     r.id.txttwo });      final listview lv = (listview) findviewbyid(r.id.android_myalertlist);     lv.setadapter(simpleadapter); }  @override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.main, menu);     return true; }    } 

i still have no clue highlight , color individual items. if can guide me thankful.

you should create own adepter class , row layout. please @ exaple.

and in getviev event should change background

public class mycustomadapter extends simpleadapter {      public mycustomadapter(context context, list<? extends map<string, ?>> data, int resource, string[] from, int[] to) {         super(context, data, resource, from, to);     }  static class viewholder {     protected textview label;     protected linearlayout layout; }      @override     public view getview(int position, view convertview, viewgroup parent) {         view view = null;         layoutinflater inflator = context.getlayoutinflater();         view = inflator.inflate(r.layout.row_task_layout, null);         final viewholder viewholder = new viewholder();         viewholder.label = (textview) view.findviewbyid(r.id.label);         viewholder.layout= (lineerlayout) view.findviewbyid(r.id.layout);          view.settag(viewholder);          viewholder holder = (viewholder) view.gettag();         holder.label.settext(data.get(position).title);          if(statement)           {              holder.layout.setbackground(background);           }         return view;     }  } 

rowlayout

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:background="#f3f3f3"     android:gravity="center"     android:padding="5dip" >      <linearlayout         android:id="@+id/layout"         android:layout_width="fill_parent"         android:layout_height="wrap_parent"         android:background="@drawable/button_style_main_single"         android:paddingleft="5dip"         android:paddingright="10dip" >          <textview             android:id="@+id/label"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:textappearance="?android:attr/textappearancesmall"         />     </linearlayout> </linearlayout>
