Hello, friends!
I have a problem with adding new items to ListView.
I use custom adapter MyListAdapter. I do that way:
public class MyView extends ListActivity{
private ArrayList<Order> m_orders = null;
privateMyListAdapter m_adapter;
private Runnable viewOrders;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
m_orders = new ArrayList<Order>();
this.m_adapter = new OrderAdapter(this, R.layout.row,
m_orders);
setListAdapter(this.m_adapter);
viewOrders = new Runnable(){
@Override
public void run() {
getOrders();
}
};
Thread thread = new Thread(null, viewOrders,
"MagentoBackground");
thread.start();
m_ProgressDialog = ProgressDialog.show(MyView.this,
"Please wait...", "Retrieving data ...", true);
}
private Runnable returnRes = new Runnable() {
@Override
public void run() {
if(m_orders != null && m_orders.size() > 0){
m_adapter.notifyDataSetChanged();
for(int i=0;i<m_orders.size();i++)
m_adapter.add(m_orders.get(i));
}
m_adapter.notifyDataSetChanged();
}
};
private void getOrders(){
try{
m_orders.addAll(/*some order collection*/)
runOnUiThread(returnRes);
}
private class OrderAdapter extends ArrayAdapter<Order> {
//code about how to get view
}
}
But when I add items to my adapter:
for(int i=0;i<m_orders.size();i++)
m_adapter.add(m_orders.get(i));
the application hangs because of m_orders increase there size,
everytime where new item adds to adapter.
Friends, do you have any ideas how to implement dynamically adding
items to custom ListAdapter? Do you see any errors in my code?
Thank you very much :)))
