Question

Hi i have one editbox in that if user type the filtering should be automatically done in listview…

from below code all is working fine but if i put space in character the listview does not display any entry..

below is my code

      adapter = new SimpleAdapter(PredefinedLocation.this, fillMaps, R.layout.list_item_deal, new String[] { "name" }, new int[] { R.id.name });
    // Adding data into listview
    lv.setAdapter(adapter);
    edtSearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub
            lv.setTextFilterEnabled(true);
            lv.setFilterText(s.toString().trim());
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub
            if(s.length()==0){
                lv.clearTextFilter();
            }
        }
    });

Like if i write “The” the result will be “The Local”, “The Adams”

but if i write “The Local” the result will be blank…. because of space in “The” & “Local” 🙁

This problem is occurring because you are using SimpleAdpater, try to use ArrayAdapter it will solve your problem. I do not know why this is!

try to put your code like this way, I have tested it works perfectly

  adapter = new ArrayAdapter<String>(PredefinedLocation.this, R.layout.list_item_deal, R.id.name, fillMaps);

    lv.setAdapter(adapter);
    edtSearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub
            lv.setTextFilterEnabled(true);
            lv.setFilterText(s.toString().trim());
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable s) {
            PredefinedLocation.this.adapter.getFilter().filter(s.toString().trim());
            /*if(s.length()==0){
                lv.clearTextFilter();
            }*/
        }
    });
