android - get clicked item from listview -

i've got problem. before modification in xml file, listview able work perfectly. now, after modifications in xml, not working properly. listview custom. so, i've created separate xml render every single row in listview.

my single row.xml code:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:id="@+id/relativelayoutsinglerowmanageaddictions" android:layout_height="40dp" android:background="@drawable/box_midbg" > <textview android:id="@+id/textviewsinglerowmanageaddictions" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentleft="true" android:layout_centervertical="true" android:layout_marginleft="17dp" android:text="textview" android:textsize="20dp" android:textcolor="#ffffff" /> <imageview android:id="@+id/imageviewsinglerowmanageaddictions" android:layout_width="20dp" android:layout_height="20dp" android:layout_alignparentright="true" android:layout_centervertical="true" android:layout_marginright="18dp" android:src="@drawable/listing_arrow" /> </relativelayout>

my main.xml code listview resides:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/main_bg_edited" > <relativelayout android:id="@+id/relativelayout1" style="@style/top_bar_style" > <imageview android:id="@+id/imageviewmanageaddictionsback" android:layout_width="30dp" android:layout_height="30dp" android:layout_alignparentleft="true" android:layout_centervertical="true" android:src="@drawable/back_arrow" android:clickable="true" /> <textview android:id="@+id/textview1" android:layout_width="wrap_content" android:layout_height="wrap_content" style="@style/header_style" android:text="manage addictions" /> <imageview android:id="@+id/imageviewmanageaddictionsadd" android:layout_width="25dp" android:layout_height="20dp" android:layout_marginright="3dp" android:layout_alignparentright="true" android:layout_centervertical="true" android:src="@drawable/plus_nav" android:clickable="true" /> </relativelayout> <listview android:id="@+id/listviewmanageaddictions" android:layout_width="290dp" android:layout_height="fill_parent" android:layout_below="@+id/relativelayout1" android:layout_centerhorizontal="true" android:layout_centerinparent="true" android:layout_margintop="12dp" android:divider="@android:color/transparent" android:dividerheight="2dp" /> </relativelayout>

and java code it:

the main bug behind that, when name using this:

view parentview = (view) arg0.getparent(); name = ((textview) parentview.findviewbyid(r.id.textviewsinglerowmanageaddictions)).gettext()+"";

the listview of record, gives name of first record only. example, if first row has textview named "gaming", when click on row, (for debugging purpose, used toast.maketext(...)) toasts "gaming" name every record in listview, though every record in listview unique. please help me out this.

lv.setonitemclicklistener(new onitemclicklistener() { public void onitemclick(adapterview<?> parent, view view, int position, long id) { // selected item string selected = ((textview) view.findviewbyid(r.id.your_textview_item_id)).gettext().tostring(); toast toast=toast.maketext(getapplicationcontext(), selected, toast.length_short); toast.show(); } });
