I found many questions and answers related to my problem. But I am unable to achieve with those. I have a ListView, in which all the datas from DB is displayed. Now I have to filter from that list, when I type letters on editext. The filter I tried was always showing error in Filter and FilterResult class. I am trying to find solution from yesterday. I know, I am doing something somewhere wrong, but I am unable to find what is that and where. How to fix this filter in my code.
Display All Data from DB:
private void getAdapterView() {
List<NewCustomerGetSetter> cont = ncdbh.getAllCustomerBikeWithStatusOfP(); // Get all the value from DB
for (NewCustomerGetSetter cn : cont) {
cust_name.add(cn.getName()); //Below all are List
cust_mobile.add(cn.getMobile1());
vehicle_number.add(cn.getBikeNo());
from_date.add(cn.getFromDate());
to_date.add(cn.getToDate());
days.add(cn.getTotalDays());
amount.add(cn.getTotalCost());
Log.d(cn.getID()+"",cn.getName()+" "+cn.getMobile1()+" "+count);
count++;
}
// Pass values to custom Adapter
list_return.setAdapter(new ReturnVehicleCustomAdapter(this, cust_name, cust_mobile, vehicle_number,from_date,to_date,days,amount));
}
AfterTextChanged Function
search.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable arg0) {
//Not coded. Depends on Shorted filter problem Solved need to think how to pass/ call that filter.
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
}
});
Custom Adapter Class:

I felt SimpleCursorAdapter was difficult to implement. So I found solution for the filtering by Filter Methods. Below is the code.
@Override
public Filter getFilter() {
if(valueFilter==null) {
valueFilter=new ValueFilter();
}
return valueFilter;
}
/**This class do all the filters*/
private class ValueFilter extends Filter {
/**Invoked in a worker thread to filter the data according to the constraint.*/
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results=new FilterResults();
if(constraint!=null && constraint.length()>0){
ArrayList<ReturnVehicleListValueGetSet> filterList=new ArrayList<ReturnVehicleListValueGetSet>();
for(int i=0;i<filter_list.size();i++){
if((filter_list.get(i).getName().toUpperCase()).contains(constraint.toString().toUpperCase())) {
ReturnVehicleListValueGetSet contacts = new ReturnVehicleListValueGetSet();
contacts.setName(filter_list.get(i).getName());
contacts.setMob(filter_list.get(i).getMob());
contacts.setVehNum(filter_list.get(i).getVehNum());
filterList.add(contacts);
}
}
results.count=filterList.size();
results.values=filterList;
}else{
results.count=filter_list.size();
results.values=filter_list;
}
return results;
}
/**Invoked in the UI thread to publish the filtering results in the user interface.*/
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint,FilterResults results) {
veh_list=(ArrayList<ReturnVehicleListValueGetSet>) results.values;
notifyDataSetChanged();
}
}
