copied!<p>You're using the standard pattern for a custom <code>ListAdapter</code> here. Not all views will be recycled e.g. when they are first created to fill the <code>ListView</code>.</p> <p>You may also want to take a reference the the <code>LayoutInflater</code> when you create the adapter to slightly improve efficiency, see snippet below</p> <pre><code> private class AlertListAdapter extends ArrayAdapter< Alert > { private ViewHolder holder; private LayoutInflater mInflater; public AlertListAdapter( Context context, List< Alert > items ) { super( context, R.layout.dashboard_layout, items ); mInflater = LayoutInflater.from( context ); } public View getView( int position, View recycledView, ViewGroup parent ) { if ( recycledView == null || recycledView.getTag() == null ) { recycledView = mInflater.inflate( R.layout.list_item, null ); holder = new ViewHolder(); holder.header = ( LinearLayout ) recycledView.findViewById( R.id.alert_list_item_header ); holder.header_text = ( TextView ) recycledView.findViewById( R.id.alert_list_item_header_text ); holder.header_count = ( TextView ) recycledView.findViewById( R.id.alert_list_item_header_count ); holder.name = ( TextView ) recycledView.findViewById( R.id.alert_list_item_name ); holder.distance = ( TextView ) recycledView.findViewById( R.id.alert_list_item_distance ); recycledView.setTag( holder ); } else { holder = ( ViewHolder ) recycledView.getTag(); } holder.header_text.setText( title.substring( 0, space ) ); holder.name.setText( title.substring( space + 1 ) ); holder.header_count.setText( count ); holder.header.setBackgroundResource( resourceID ); return recycledView; } } </code></pre> <p>Essentially you must always be prepared for <code>v.getTag()</code> to return null and inflate a new <code>View</code> accordingly.</p>
