    copied!<p>In my application I'm using customized listView with <strong>Text view</strong> and <strong>Button</strong> to change the button image. After I click the button in 1st position, the image of the button changed but when I scroll down the listView, the image set changed to some other position.</p> <pre><code> public class CustomListViewAdapter_ringtone extends BaseAdapter { ArrayList&lt;HashMap&lt;String, String&gt;&gt; list; Activity activity; public CustomListViewAdapter_ringtone(Activity activity,ArrayList&lt;HashMap&lt;String, String&gt;&gt; list) { super(); this.activity = activity; this.list = list; } @Override public int getCount() { // TODO Auto-generated method stub return list.size(); } @Override public Object getItem(int position) { // TODO Auto-generated method stub return list.get(position); } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } class ViewHolder { Button play; TextView tarck_name,singer; } @Override public View getView(final int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub final ViewHolder holder; LayoutInflater inflater = activity.getLayoutInflater(); if (convertView == null) { convertView = inflater.inflate(R.layout.test, null); holder = new ViewHolder(); holder.tarck_name = (TextView)convertView.findViewById(R.id.track_name); holder.singer = (TextView)convertView.findViewById(R.id.singer); holder.play = (Button)convertView.findViewById(R.id.play_pause_btn); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } HashMap&lt;String, String&gt; map = list.get(position); holder.tarck_name.setText(map.get("track_name")); holder.singer.setText(map.get("sing")); holder.play.setTag(position); holder.play.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub holder.play.setBackgroundResource(R.drawable.pausebtn); //here am set the background for the button but when i scroll down the image changed to some other positon } }); return convertView; } } </code></pre>
