Android ListView not redraw properly -

i have listfragment custom row. problem when scroll items, underlying items don't disappear. remains visible , didnt't find solution problem.

loader loads items database through arrayadapter

         @override       public view getview(int position, view row, viewgroup parent)       {          viewholder holder = null;          if(row == null)         {           row = minflater.inflate(r.layout.list_item_expense, null, false);           holder = new viewholder();           holder.layout = (checkablelinearlayout)row.findviewbyid(r.id.mylinearlayout);           holder.id = ((textview)row.findviewbyid(r.id.id));           holder.category = ((textview)row.findviewbyid(r.id.category));           holder.date = ((textview)row.findviewbyid(r.id.date));           holder.note = ((textview)row.findviewbyid(r.id.note));            row.settag(holder);           // watch checked state , remember           holder.layout.setcheckchangelistener(expenselistadapter.this);         }         else         {           holder = (viewholder)row.gettag();         }      expense item = getitem(position);     holder.id.settext(integer.tostring(item.getid()));     holder.category.settext(integer.tostring(item.getcategory()));     holder.note.settext(item.getnote());     holder.date.settext(item.getdatedisplay());      holder.layout.settag(r.id.mylinearlayout, position);     // restore checked state     final listview lv = (listview)parent;     holder.layout.setchecked(lv.isitemchecked(position));      return row;   } 

row layout is:

    <?xml version="1.0" encoding="utf-8"?> <com.nutelar.expensemaster.checkablelinearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/mylinearlayout"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="horizontal" >      <textview         android:id="@+id/id"         android:layout_width="48dip"         android:layout_height="wrap_content"         android:clickable="false"         android:focusable="false"         android:textcolor="@color/textcolor"         android:textisselectable="false" />      <textview         android:id="@+id/category"         android:layout_width="48dip"         android:layout_height="wrap_content"         android:clickable="false"         android:focusable="false"         android:textcolor="@color/headercolor"         android:textisselectable="false" />      <textview         android:id="@+id/date"         android:layout_width="248dip"         android:layout_height="wrap_content"         android:clickable="false"         android:focusable="false"         android:textisselectable="false" />      <textview         android:id="@+id/note"         android:layout_width="0dip"         android:layout_height="wrap_content"         android:layout_gravity="center_vertical"         android:layout_weight="1.0"         android:clickable="false"         android:focusable="false"         android:textisselectable="false" />      <com.nutelar.expensemaster.inertcheckbox         android:id="@+id/itemcheckbox"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparentright="true"         android:layout_centervertical="true"         android:layout_marginright="5dp"         android:focusable="false" />  </com.nutelar.expensemaster.checkablelinearlayout> 

when scroll up, previous rows remains "underlying" while new data loads in "foreground". rows looks shifted down.
