SearchField
Please Login to Remove!
Hi,
I want to achieve similar logic as it is in the AddressBook for searching the contacts.
To do this i have written the code which is as follows,
AddressBook()
{
_addContact = new ADD();
_table =new Vector();
// setStatus(listField.getSearchBar())
// LabelField lbl = new LabelField("Address Book ".concat(navLabel), 0, -1, Field.FIELD_HCENTER
//);
listField = new ListField();
listField.setCallback(this);
//listField.setSearchable(true);
editField = new BasicEditField("Find: ", "")
{
public void paint(Graphics graphics) {
graphics.setBackgroundColor(0xCCFF66);
graphics.drawRect(0,15,35,1);
graphics.clear();
super.paint(graphics);
}
};
editField.setChangeListener(this);
add(editField);
add(listField);
reloadContactList();
}
public boolean onSavePrompt()
{
return true;
}
int sortIndex=0;
//String entry;
public void fieldChanged(Field field, int context)
{
if(field==editField)
{
String prefix = editField.getText();
for (int a=0; a<_table.size();a++)
{
Object obj= _table.elementAt(a);
if(obj instanceof String)
{
String entry =(String)obj;
if(entry.startsWith(prefix));
{
sortIndex=_table.indexOf(entry);
break;
//
}
}
}
int n=indexOfList(listField,"Mr",1);
Dialog.inform(" "+n);
listField.invalidate();
}
}
private boolean reloadContactList()
{
try {
blackBerryContactList =
(ContactList)PIM.getInstance().openPIMList
(PIM.CONTACT_LIST, PIM.READ_ONLY);
Enumeration allContacts = blackBerryContactList.items();
blackBerryContacts = enumToVector(allContacts);
listField.setSize(blackBerryContacts.size());
return true;
}
catch (PIMException e)
{
return false;
}
}
//Convert the list of contacts from an Enumeration to a Vector
private Vector enumToVector(Enumeration enum1) {
Vector v = new Vector();
if (enum1 == null)
return v;
while (enum1.hasMoreElements()) {
v.addElement(enum1.nextElement());
}
return v;
}
int move=0;
//ListFieldCallback methods
public void drawListRow(
ListField fieldVar,
Graphics graphics,
int index, int y, int width
){
if ( listField == fieldVar
&& index < blackBerryContacts.size())
{
blackBerryContact =
(BlackBerryContact)blackBerryContacts.elementAt(in dex);
String[] name = blackBerryContact.getStringArray(Contact.NAME, 0);
boolean found = false;
String nameseg;
String prefix;
String givenName;
String familyName;
StringBuffer sb = new StringBuffer();
if ((prefix = name[Contact.NAME_PREFIX]) != null) {
sb.append(prefix);
found = true;
}
if ((givenName = name[Contact.NAME_GIVEN]) != null) {
if (found) {
sb.append(' ');
}
sb.append(givenName);
found = true;
}
if ((familyName = name[Contact.NAME_FAMILY]) != null) {
if (found) {
sb.append(' ');
}
sb.append(familyName);
}
_table.insertElementAt(sb.toString(),move);
graphics.drawText(sb.toString(), 0, y, 0, width);
}
move++;
}
public Object get(ListField fieldVar, int index)
{
if (listField == fieldVar)
{
//If index is out of bounds an exception will be thrown,
//but that's the behaviour we want in that case.
return blackBerryContacts.elementAt(index);
}
return null;
}
public int getPreferredWidth(ListField fieldVar)
{
//use all the width of the current LCD
return Graphics.getScreenWidth();
}
public int indexOfList
(ListField fieldVar,String prefix,int start)
{
return listField.indexOfList(prefix, start);
}
But my ListOfIndex method doesn't work,it's returning -1 value.
How to resolve this problem,Is there something wrong in the above code.
