ListView onItemLongClickListener is not working properly

I am working on a ListView and I have used setBackgroundColor inside onItemLongClickListener on the selected item. My problem is that when I am doing this and scrolling, it is setting color of some invisible child of ListView too. How can it be solved.

Try putting the following attributes in your xml:

`

<ListView       
        android:dividerHeight="1dp"
        android:scrollingCache="false" >

`

In your adapter class:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if(convertView == null) {
        convertView = inflater.inflate(...);
    }
    convertView.setBackgroundColor(defaultcolor);
    ...
}

This however will overwrite the background you set in the onlongclicklistener when that view would be redrawn. So you might want to keep a list of the positions of the clicked items so you can set these in the getView method.

this is caused since a listview uses old views in order to avoid re-creation of views when you scroll.

in fact , this is common to all of the adapterView classes .

in order to handle this , store the status of the position of the view (using an arrayList or whatever collection you wish) and on the getView , if the position is set in the list to be of this background , use this background , otherwise use the default background.

for more information about listview , either read the API , or (and i highly recommend it) watch the video "the world of listView" .
