Android List View shows only 10 items

Hi every 1,
I’m trying backendless for the first time , i have an app which insert and retrieve contacts info,
my issue that my list view shows only 10 items (last 10 inserted items) while my DB has more then 20 !! ??
this my code to load the data

public void loaddata(){
 if (contactslist !=null){ // if its has data we clear it to prevent duplicate data in case of refresh
 String condition = "useremail = '"+ getIntent().getStringExtra("UserEmail")+"'";
 BackendlessDataQuery query= new BackendlessDataQuery();
 Backendless.Persistence.of(ContactsObject.class).find(query, new AsyncCallback<BackendlessCollection<ContactsObject>>() {
 public void handleResponse(BackendlessCollection<ContactsObject> contactsObjectBackendlessCollection) {
 contactslist=contactsObjectBackendlessCollection.getData(); // return list
 ContactAdapter adapter= new ContactAdapter(Contacts.this,contactslist);
 public void handleFault(BackendlessFault backendlessFault) {
 Toast.makeText(Contacts.this, "Error "+backendlessFault, Toast.LENGTH_SHORT).show();

and this is my custom adapter

public class ContactAdapter extends ArrayAdapter<ContactsObject>{
private Context context; 
private List<ContactsObject> contactslist; 
public ContactAdapter(Context context, List<ContactsObject> list){
public class ViewHolder{ 
 TextView tvname,tvemail,tvphone;
 public ViewHolder(View v){
 TextView tvname=(TextView) v.findViewById(;
 TextView tvemail=(TextView) v.findViewById(; 
 TextView tvphone=(TextView) v.findViewById(; 
public View getView(int position, View convertView, ViewGroup parent) {
 ViewHolder myholder=null;
 if (convertView == null){
 LayoutInflater inflater =(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
 convertView = inflater.inflate(R.layout.ctninforow,parent,false);
 myholder=new ViewHolder(convertView);
 myholder =(ViewHolder) convertView.getTag();
 return convertView; 

i really don’t know what is wrong ,please any ideas will be much appreciated

See the pageSize parameter:

Thanx Shai

this pageSize parameter could be a very helpful parameter but i think the Backendless team should make the query as default ( retrieve all the data ) unless the developer wants to use some where clause or set this parameter to what ever he needs

All the data would not be a reasonable default - What if there are 100,000 items?

All databases and api systems have a default set and it is up to the client developer to do paging / infinite scroll.
I do however agree that 10 is a very low default.
