Hi, Yuvidroid no I had not called startActivity. Here is my code
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
try
{
System.out.println ("Inside try");
//sampleDB = this.openOrCreateDatabase(SAMPLE_DBNAME,
MODE_PRIVATE, null);
sampleDB = this.openOrCreateDatabase(SAMPLE_DBNAME,
MODE_PRIVATE, null);
System.out.println ("Inside try...");
Cursor c = sampleDB.rawQuery ("SELECT _id,RoomName,
SwitchFullName FROM SwitchTable ",null);
System.out.println (c.getCount()+"%%%%");
startManagingCursor(c);
System.out.println ("After startManagingCursor(c))");
String[] columns = new String[] {"RoomName",
"SwitchFullName"};
int[] names = new int[] {R.id.room, R.id.switch1};
myAdapter = new SimpleCursorAdapter(this,
R.layout.roomswitchlist, c, columns,names);
setListAdapter(myAdapter);
}
catch (SQLiteException se )
{
Log.e(getClass().getSimpleName(), "Could not create or Open
the database");
}
finally
{
//sampleDB.close();
}
registerForContextMenu(getListView());
}
public void onCreateContextMenu(ContextMenu menu, View
v,ContextMenuInfo menuInfo)
{
try
{
info = (AdapterView.AdapterContextMenuInfo) menuInfo;
}
catch (ClassCastException e)
{
e.printStackTrace();
}
long id = getListAdapter().getItemId(info.position);
Object obj = getListAdapter().getItem((int) id);
System.out.println ("&&&!!!@@@"+obj.toString());
str = obj.toString();
System.out.println ("$$$$$"+str);
/*rName = str.substring(0,str.indexOf("-"));
sName = str.substring(str.indexOf("-")+1);
test = true;*/
for (int i=0;i<menuItems.length;i++)
{
System.out.println (menuItems[i]);
}
System.out.println ("************************");
for (int i = 0; i<menuItems.length; i++)
{
menu.add(Menu.NONE, i, i, menuItems[i]);
}
cursor = (Cursor) myAdapter.getItem((int) id);
//long phoneId =
cursor.getLong(cursor.getColumnIndex(People.PRIMARY_PHONE_ID));
}
public boolean onContextItemSelected(MenuItem item)
{
AdapterView.AdapterContextMenuInfo info =
(AdapterView.AdapterContextMenuInfo)item.getMenuInfo();

System.out.println ("Delete Room name and switch name
are"+delRoomName+":"+delSwitchName);

alt_bld.setMessage("Do you want to Delete "+delSwitchName
+" ?")
.setCancelable(false)

DialogInterface.OnClickListener()

startActivity(getIntent()); //Restarts activity for
menu refresh
}
catch (Exception e)
