    <p>I am confused in changing the background colour of a particular row in an list view, below is the code I tried. Different rows gets highlighted as i scroll the list, I could like to understand the reason behind this. The logic seems to quite simple, but the results are unpredictable. How am I supposed to achieve this. </p> <pre><code> @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.rows_for_layout, null); holder = new ViewHolder(); holder.name = (TextView)convertView.findViewById(R.id.name); holder.rated=(ImageView)convertView.findViewById(R.id.rated); convertView.setTag(holder); }else { holder = (ViewHolder) convertView.getTag(); } //selected_position is the position where the list has to be highlighted if(position==selected_position){ holder.name.setText(elements.get(position).get("name")); convertView.setBackgroundResource(R.drawable.highlight_this); holder.rated.setBackgroundResource(R.drawable.star_image); }else{ holder.name.setText(elements.get(position).get("name")); } return convertView; }//getView ![alt text][1] </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
