<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#ffffff" android:orientation="vertical" >  <linearlayout     android:layout_width="match_parent"     android:layout_height="50dp"     android:background="@drawable/activated_bg" >      <imageview         android:id="@+id/imageview1"         android:layout_width="30dp"         android:layout_height="30dp"         android:layout_gravity="center"         android:layout_marginleft="5dp"         android:padding="4dp"         android:src="@drawable/checkbox" />      <linearlayout         android:layout_width="wrap_content"         android:layout_height="match_parent"         android:layout_weight="0.73"         android:orientation="vertical" >          <textview             android:id="@+id/id_row"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:visibility="gone" />          <textview             android:id="@+id/title_row"             android:layout_width="match_parent"             android:layout_height="25dp"             android:layout_margintop="5dp"             android:layout_marginleft="5dp"             android:padding="2dp"             android:text="title"             android:textcolor="#000000"             android:textsize="16sp"             android:textstyle="bold" />          <textview             android:id="@+id/content_row"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:visibility="gone" />          <textview             android:id="@+id/sendtime_row"             android:layout_width="match_parent"             android:layout_height="25dp"                             android:layout_marginleft="5dp"             android:maxlength="100"             android:paddingbottom="2dp"             android:paddingleft="3dp"             android:paddingright="3dp"             android:text="date"             android:textcolor="#808080"             android:textsize="15sp" />     </linearlayout>  </linearlayout> 

in activity have listview put this:

create global variable: bundle savedinstancestate;

@override     protected void onrestart() {         // todo auto-generated method stub         oncreate(savedinstancestate);         super.onrestart();     } 

in oncreate handle listview or set adapter listview.

here simple example how this:

package com.example.testapp;  import com.example.main.util.testactivity;  import android.app.listactivity; import android.content.context; import android.content.intent; import android.graphics.color; import android.os.bundle; import android.view.layoutinflater; import android.view.view; import android.view.view.onclicklistener; import android.view.viewgroup; import android.widget.baseadapter; import android.widget.textview;  public class mainactivity extends listactivity {      private static final string[] countries = new string[] { "belgium",             "france", "france_", "italy", "germany", "spain" };     private myarrayadapter adapter;     bundle savedinstancestate;      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);          setcontentview(r.layout.activity_main);          adapter = new myarrayadapter(mainactivity.this);         getlistview().setadapter(adapter);     }      private class myarrayadapter extends baseadapter {          private layoutinflater minflater;          public myarrayadapter(context con) {             // todo auto-generated constructor stub             minflater = layoutinflater.from(con);         }          @override         public int getcount() {             // todo auto-generated method stub             return countries.length;         }          @override         public object getitem(int position) {             // todo auto-generated method stub             return position;         }          @override         public long getitemid(int position) {             // todo auto-generated method stub             return position;         }          @override         public view getview(int position, view convertview, viewgroup parent) {             // todo auto-generated method stub             final listcontent holder;             view v = convertview;             if (v == null) {                 v = minflater.inflate(r.layout.my_spinner_style, null);                 holder = new listcontent();                  holder.name = (textview) v.findviewbyid(r.id.textview1);                  v.settag(holder);             } else {                  holder = (listcontent) v.gettag();             }              holder.name.settext("" + countries[position]);             holder.name.setonclicklistener(montitleclicklistener3);              return v;         }      }      static class listcontent {          textview name;      }      public onclicklistener montitleclicklistener3 = new onclicklistener() {         public void onclick(view v) {             final int position = getlistview().getpositionforview(                     (view) v.getparent());             v.setbackgroundcolor(color.red);             startactivity(new intent(mainactivity.this, testactivity.class));             // log.d("you click on ratings", "you click on ratings");             // v.setbackgroundcolor(color.white);         }     };      protected void onrestart() {         // adapter.notifydatasetchanged();         oncreate(savedinstancestate);     }; } 

or can same style reverse. mean have deselect litview after go next activity. can in list item click or whatever have used..
