My AutoCompleteTextView works very well but it hasn't get the other values (for example plant, qty, etc.) according to the selected value from the AutoCompleteTextView.
My JSON response
{
"feed": [{
"material": "2000000",
"plant": "2100",
"qty": "4",
"ton": "13.68",
"val": "5333.44",
"des": "4.00-08 06PR C.AUTO ZEETEX",
"matgrp": "FG0002"
}, {
"material": "2000001",
"plant": "2100",
"qty": "13",
"ton": "46.15",
"val": "20566.52",
"des": "4.00-08 06PR C.M - ZEETEX",
"matgrp": "FG0002"
}]
}
JsonParse class. AutoCompleteTextView works perfectly.
public List<Product> getParseJsonWCF(String sName) {
List<Product> ListData = new ArrayList<Product>();
try {
String temp = sName.replace(" ", "%20");
URL js = new URL(url + temp);
URLConnection jc = js.openConnection();
BufferedReader reader = new BufferedReader(new InputStreamReader(jc.getInputStream()));
String line = reader.readLine();
JSONObject jsonResponse = new JSONObject(line);
JSONArray jsonArray = jsonResponse.getJSONArray("feed");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject r = jsonArray.getJSONObject(i);
ListData.add(new Product(r.getInt("qty"), r.getString("des"), r.getString("plant"), r.getString("matgrp")));
}
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
return ListData;
}
This is my MaterialSuggestionAdapter class.
public class MaterialSuggestionAdapter extends ArrayAdapter<String> {
private List<String> suggestions;
private List<String> originals;
private List<Product> new_suggestions;
private String matCodeName;
public MaterialSuggestionAdapter(Activity context, String matFilter) {
super(context, android.R.layout.simple_dropdown_item_1line);
suggestions = new ArrayList<String>();
originals = new ArrayList<String>();
}
@Override
public int getCount() {
return suggestions.size();
}
@Override
public String getItem(int position) {
return suggestions.get(position);
}
@Override
public Filter getFilter() {
Filter filter = new Filter() {
@Override
protected FilterResults performFiltering(CharSequence charSequence) {
FilterResults filterResults = new FilterResults();
JsonParseMaterial jp = new JsonParseMaterial();
if ((charSequence == null || charSequence.length() == 0)) {
filterResults.values = originals;
filterResults.count = originals.size();
} else {
// A class that queries a web API, parses the data and
// returns an ArrayList<Product>
new_suggestions = jp.getParseJsonWCF(charSequence.toString());
suggestions.clear();
for (int i = 0; i < new_suggestions.size(); i++) {
if (new_suggestions.get(i).getMatName().toUpperCase().startsWith(charSequence.toString().toUpperCase())) {
suggestions.add(new_suggestions.get(i).getMatName());
}
}
// Now assign the values and count to the FilterResults
// object
filterResults.values = suggestions;
filterResults.count = suggestions.size();
}
return filterResults;
}
@Override
protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
if (filterResults != null && filterResults.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
};
return filter;
}
}
This is my AutoCompleteTextView.
final AutoCompleteTextView acTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);
final MaterialSuggestionAdapter adapter = new MaterialSuggestionAdapter(this, acTextView.getText().toString());
acTextView.setAdapter(adapter);
Bundle gt = getIntent().getExtras();
dealerName = gt.getString("abc");
//textView.setText(dealerName);
getSupportActionBar().setTitle(dealerName);
acTextView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView < ? > adapterView, View view, int i, long l) {
//vPager = (ViewPager) findViewById(R.id.viewPager);
//vPager.setAdapter(new MyViewPagerAdapter(getSupportFragmentManager()));
String newName = adapterView.getItemAtPosition(i).toString();
//selectItemAdapter.add();
//String s = item.getItemName();
if (!newName.equals("")) {
if (myRecyclerViewAdapter.getItemCount() > 1) {
myRecyclerViewAdapter.add(1, newName);
} else {
myRecyclerViewAdapter.add(0, newName);
}
}
}
});
This is my stack trace friend.

this is MaterialSuggestionAdapter.java: Line 130
return mResults.get(index);
In your MaterialSuggestionAdapter create a method like following
public Product getProduct(int position){
return new_suggestions.get(position);
}
then use it to retrieve the product like this
//creating and setting the MaterialSuggestionAdapter
final MaterialSuggestionAdapter adapter = new MaterialSuggestionAdapter(this, acTextView.getText().toString());
acTextView.setAdapter(adapter);
acTextView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView < ? > adapterView, View view, int i, long l) {
MyViewPagerAdapter(getSupportFragmentManager()));
String newName = adapterView.getItemAtPosition(i).toString();
// getting the product. you can access all the details inside the
// Product object. Ex: selectedProduct.getQty();
Product selectedProduct = adapter.getProduct(position);
if (!newName.equals("")) {
if (myRecyclerViewAdapter.getItemCount() > 1) {
myRecyclerViewAdapter.add(1, newName);
} else {
myRecyclerViewAdapter.add(0, newName);
}
}
}
});
UPDATE
Refactor your MaterialSuggestionsAdapter like below. I am posting one of my adapter classes that geocodes locations. You can simply replace it with your logic and model
public class GeoCodeAutoCompleteAdapter extends BaseAdapter implements Filterable {
private static final int MAX_RESULTS = 5;
private Context mContext;
//replace this with your List<Product>
private List<GeoCodeAutoCompleteResult> mResults = new ArrayList<>();
public GeoCodeAutoCompleteAdapter(Context context) {
mContext = context;
}
@Override
public int getCount() {
return mResults.size();
}
@Override
public GeoCodeAutoCompleteResult getItem(int index) {
return mResults.get(index);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.list_item_geo_code_result, parent, false);
}
TextView tvResult = ButterKnife.findById(convertView, R.id.tvResult);
tvResult.setText(getItem(position).getAddress());
return convertView;
}
@Override
public Filter getFilter() {
return new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults filterResults = new FilterResults();
if (constraint != null) {
//replace findLocations method with your search logic
List locations = findLocations(mContext, constraint.toString());
// Assign the data to the FilterResults
filterResults.values = locations;
filterResults.count = locations.size();
}
return filterResults;
}
@SuppressWarnings("unchecked cast")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
if (results != null && results.count > 0) {
mResults = (List<GeoCodeAutoCompleteResult>) results.values;
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
};
}
// replace this method with your own search logic, Return the list of model you want
private List<GeoCodeAutoCompleteResult> findLocations(Context context, String queryText) {
List<GeoCodeAutoCompleteResult> searchResults = new ArrayList<>();
Geocoder geocoder = new Geocoder(context, context.getResources().getConfiguration().locale);
List<Address> addresses;
try {
addresses = geocoder.getFromLocationName(queryText, MAX_RESULTS);
for (int i = 0; i < addresses.size(); i++) {
Address address = addresses.get(i);
if (address.getMaxAddressLineIndex() != -1) {
searchResults.add(new GeoCodeAutoCompleteResult(address));
}
}
} catch (IOException e) {
e.printStackTrace();
}
return searchResults;
}
}
Setting the adapter and retrieving clicked item
mGeoCodeAutoCompleteAdapter = new GeoCodeAutoCompleteAdapter(getActivity());
atvPlaceSearch.setAdapter(mGeoCodeAutoCompleteAdapter);
atvPlaceSearch.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
GeoCodeAutoCompleteResult result = mGeoCodeAutoCompleteAdapter.getItem(position);
//set the text to clicked result
atvPlaceSearch.setText(result.getShortAddress());
}
});
