android - Delete a custom item when the button in it get clicked -

i have listview custom list items having following layout:

<?xml version="1.0" encoding="utf-8"?> <linearlayout       xmlns:android="http://schemas.android.com/apk/res/android"       android:orientation="horizontal"       android:layout_width="match_parent"        android:layout_height="wrap_content">            <textview android:id="@+id/itemnumbertext"                 android:text="1." android:textsize="16sp"                android:textstyle="bold"                 android:layout_height="match_parent"                android:layout_width="33dp"                 android:gravity="center_vertical|center_horizontal"/>          <imageview android:src="@drawable/item"                android:id="@+id/imageview1"                 android:layout_height="match_parent"                android:layout_width="47dp"/>          <linearlayout android:id="@+id/linearlayout1"                android:orientation="vertical"                android:layout_height="wrap_content"                android:layout_width="143dp">                <textview android:text="name"                          android:id="@+id/text1"                          android:layout_width="wrap_content"                          android:layout_height="wrap_content"                          android:textsize="16sp" android:textstyle="bold"                           android:textcolor="#f5cd10"></textview>               <linearlayout android:id="@+id/linearlayout2"                      android:layout_height="wrap_content"                     android:layout_width="match_parent">                      <textview android:id="@+id/text2"                               android:layout_height="wrap_content"                                android:text="amount"                                android:textcolor="#ffffff"                               android:layout_width="wrap_content"/>                      <textview android:text=" unit"                                android:id="@+id/text4"                               android:layout_width="wrap_content"                               android:layout_height="wrap_content"/>             </linearlayout>              <textview android:text="price"                       android:id="@+id/text3"                       android:layout_width="wrap_content"                       android:layout_height="wrap_content"/>          </linearlayout>         <relativelayout android:layout_height="match_parent"                          android:id="@+id/relativelayout1"                         android:layout_width="match_parent">              <button android:layout_width="wrap_content"                      android:layout_height="wrap_content"                       android:onclick="itemdeletebuttonclicked"                      android:background="@drawable/item_button_style_selector"                      android:text="delete item" android:id="@+id/list_button"                      android:layout_alignparentright="true"                      android:layout_alignparentbottom="true"/>         </relativelayout>  </linearlayout> 

as seen above mentioned method button, typing

android:onclick="itemdeletebuttonclicked"  

here's code method:

 public void itemdeletebuttonclicked(view v)  {     int index;     index=itemslistview.getselecteditemposition();//itemslistview listview     list.remove(index);//list list of data shown in listview     adapter.notifydatasetchanged();  } 

i have used simpleadapter , it's not customized. here is:

//create base adapter listview  adapter= new simpleadapter(               this, list, r.layout.detailed_info_list_item,                 new string[] {"number","item","amount","price","unit"},                 new int[] {r.id.itemnumbertext,r.id.text1,r.id.text2, r.id.text3,r.id.text4}               );  setlistadapter(adapter); 

but it's not working. it's not deleting clicked item. please give me suggestions.

the method getselecteditemposition() returns right value if list item selected. if press button inside list item list item wont selected according list view. check value of index variable after have called getselecteditemposition(). if -1 no list item selected , have selection of right list item yourself.
