    <p>I came across some odd problem which some how deals with android OS versions. My problem is that the following given code is working properly as I want in android version 4 but the same programme working in a reverse manner in android version 2.3</p> <p>public class FeturesList extends Activity {</p> <pre><code>ImageView imgFeture; ListView listview; ArrayList&lt;String&gt; values; CustomListAdapter adapter; public static boolean itemOnView = false; int tempPos; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_fetures_list); listview = (ListView) findViewById(R.id.listView1); values=new ArrayList&lt;String&gt;(); values.add(" ESSENTIAL "); values.add(" EMERGENCY "); values.add(" ENTERTAINMENT "); values.add(" VIDEO CALL "); values.add(" DOCTORS "); values.add(" SOCIETY "); values.add(" FAMILY "); values.add(" OTHERS "); values.add(" WHAT'S NEW "); imgFeture = (ImageView) findViewById(R.id.imageFeatures); adapter = new CustomListAdapter(this, values); listview.setAdapter(adapter); listview.setSelection(0); listview.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; arg0, View v, int position, long id) { imgFeture.setBackgroundDrawable(getResources().getDrawable(getResources().getIdentifier("drawable/feature_"+position,"drawable",getPackageName()))); tempPos = position; for(int i = 0; i &lt; arg0.getChildCount(); i++){ if(i == position){ arg0.getChildAt(i).setBackgroundColor(Color.WHITE); TextView text = (TextView) v.findViewById(R.id.rowListTextView); text.setTextColor(Color.BLACK); adapter.notifyDataSetChanged(); }else{ arg0.getChildAt(i).setBackgroundColor(Color.MAGENTA); } } } }); } public class CustomListAdapter extends ArrayAdapter&lt;String&gt; { Activity context; ArrayList&lt;String&gt; row=null; LayoutInflater inflator=null; public CustomListAdapter(Activity context,ArrayList&lt;String&gt; row) { super(context,R.layout.listrow,row); this.context=context; this.row=row; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub View rowView=convertView; /*FilterItem item = (FilterItem)this.getItem(position);*/ if(convertView==null) { inflator=context.getLayoutInflater(); final ViewHolder holder=new ViewHolder(); rowView=inflator.inflate(R.layout.listrow, null); holder.rowText=(TextView)rowView.findViewById(R.id.rowListTextView); rowView.setTag(holder); } final ViewHolder hold=(ViewHolder)rowView.getTag(); hold.rowText.setText(row.get(position)); if(tempPos != position){ hold.rowText.setTextColor(Color.WHITE); } return rowView; } } static class ViewHolder { TextView rowText; } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_fetures_list, menu); return false; } @Override public void onBackPressed() { // TODO Auto-generated method stub super.onBackPressed(); overridePendingTransition(R.anim.slide_out_left,R.anim.slide_out_right); this.finish(); } </code></pre> <p>In android 4.0 the variable "position" of setOnItemClickListener() is working proper i.e if I click on 0 or 1 or 2 than it showing proper position as 0, 1, or 2 respectivily but the same thing is working reverse in android 2.3 as for position 0 it is taking position as 8 like 0-8, 1-7, 2-5, 4-4, 5-4 and so on... Please suggest me how to overcome this.</p>

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.
