How to implement autocompletetextview with listview?

First create a custom adapter implements filterable:
public class MyFilterableAdapter extends BaseAdapter implements Filterable {
private Context context;
private List<String> items;
private List<String> filteredItems;
private ItemFilter mFilter = new ItemFilter();
public MyFilterableAdapter(Context context, List<String> items) {
//super(context, R.layout.your_row, items);
this.context = context;
this.items = items;
this.filteredItems = items;
}
@Override
public int getCount() {
return filteredItems.size();
}
@Override
public Object getItem(int position) {
return filteredItems.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.row_search_merchant, parent, false);
viewHolder = new ViewHolder();
viewHolder.tvTitle = (TextView) convertView.findViewById(R.id.tv_title);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
String location = filteredItems.get(position);
if (!location.isEmpty() || viewHolder != null) {
viewHolder.tvTitle.setText(location);
}
return convertView;
}
public static class ViewHolder {
TextView tvTitle;
}
private class ItemFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
int count = items.size();
final List<String> tempItems = new ArrayList<>(count);
for (int i = 0; i < count; i++) {
if (items.get(i).toLowerCase().contains(filterString)) {
tempItems.add(items.get(i));
}
}
results.values = tempItems;
results.count = tempItems.size();
return results;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredItems = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}
public Filter getFilter() {
return mFilter;
}
}
And than create a textwatcher
public class MyTextWatcher implements TextWatcher {
private MyCustomAdapter lAdapter;
public MyTextWatcher(MyCustomAdapter lAdapter) {
this.lAdapter = lAdapter;
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
lAdapter.getFilter().filter(s.toString().toLowerCase());
}
}
And finally add your TextWatcher to your Search Edit Text:
final MyCustomAdapter lAdapter = new MyCustomAdapter(context, items);
EditText etSearch = (EditText) view.findViewById(R.id.et_search);
etSearch.addTextChangedListener(new SearchTextWatcher(lAdapter));
I hope this'll help you.

I am getting response from server and display it using listview and it works fine,now what I am trying is i added autocompletetextview to search items by name,but when i run my app it crashes and showing errors..i already ask this
Tab1Activity.java
public class Tab1Activity extends ListActivity{ private ProgressDialog pDialog; JSONArray Product=null; private ListView listview; ArrayList<HashMap<String,String>> aList; ArrayList<HashMap<String, String>> arrayTemplist;
