xml - Android ListView :: Scrolling ListView while item is selected causes display problems -


alright, i'm using listview custom adapter. works fine , dandy...until user selects listview row , tries scroll.

when user selects row, background color of row changes blue (which good).

but, problems occur when begin scrolling: when scroll past selected row, blue fixes either bottom or top of listview, depending on way scrolling.

selected row changes color on touch (good)
selected row looks good


part of background of selected row fixed top when scrolling down (not good)

here source code:

list view i'm populating dynamically

<listview      android:id="@+id/tallydatalistview"      android:layout_height="wrap_content"      android:layout_width="fill_parent"      android:divider="#000000"      android:dividerheight="1dp"      android:fadescrollbars="false"      android:listselector="#0099ff" >


layout_list_view_row.xml

<?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:orientation="horizontal" >      <view         android:focusable="false"         android:focusableintouchmode="false"         style="@style/tablesideborderline" />      <textview         android:id="@+id/column_pipe_number"         android:layout_height="wrap_content"         android:layout_width="0dp"         android:layout_weight="1"         style="@style/tablecolumn"         xmlns:android="http://schemas.android.com/apk/res/android" />      <view         android:focusable="false"         android:focusableintouchmode="false"         style="@style/tablecolumndivider" />      <textview         android:id="@+id/column_total_length"         android:layout_height="wrap_content"         android:layout_width="0dp"         android:layout_weight="1"         style="@style/tablecolumn"         xmlns:android="http://schemas.android.com/apk/res/android" />      <view         android:focusable="false"         android:focusableintouchmode="false"         style="@style/tablecolumndivider" />      <textview         android:id="@+id/column_adjusted"         android:layout_height="wrap_content"         android:layout_width="0dp"         android:layout_weight="1"         style="@style/tablecolumn"         xmlns:android="http://schemas.android.com/apk/res/android" />      <view         android:focusable="false"         android:focusableintouchmode="false"         style="@style/tablesideborderline" />  </linearlayout>



my custom adapter

import android.app.activity; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.arrayadapter; import android.widget.textview;  import java.util.arraylist;  public class listviewadapter extends arrayadapter<string>{      layoutinflater inflater;     private final arraylist<string> adjustedvalues;     private final arraylist<string> pipenumbers;     private final arraylist<string> totallengthvalues;      public listviewadapter(activity pcontext, arraylist<string> ppipenumbers,                            arraylist<string> ptotallengthvalues, arraylist<string> padjustedvalues)     {          super(pcontext, r.layout.layout_list_view_row, padjustedvalues);          adjustedvalues = padjustedvalues;         pipenumbers = ppipenumbers;         totallengthvalues = ptotallengthvalues;          inflater = pcontext.getlayoutinflater();      }      @override     public view getview(int pposition, view pview, viewgroup pparent)     {          view view = inflater.inflate(r.layout.layout_list_view_row, pparent, false);          textview col1 = (textview)view.findviewbyid(r.id.column_pipe_number);         col1.settext(pipenumbers.get(pposition));         textview col2 = (textview)view.findviewbyid(r.id.column_total_length);         col2.settext(totallengthvalues.get(pposition));         textview col3 = (textview)view.findviewbyid(r.id.column_adjusted);         col3.settext(adjustedvalues.get(pposition));          return view;      } }

keep reference selected row position in adapter,

int selectedpos = -1;

the value -1 when no row selected. , in onitemclicklistener of listview,update selectedpos clicked position , call notifydatasetchanged() on adapter. in getview method of adapter, check selectedpos value , highlight row accordingly.
