Search items from listview with custom adapter

Am trying search from listview using custom adapter. i have search widget in toolbar menu and i can display widget. when i click on search icon, it expands, but when i start typing, search does not happen and list gets cleared. can someone plz trace this issue .
Here's my code from Main Activity:
public class VideoActivity extends BaseActivity {
ListView listView;
ArrayList<Video> videoArrayList;
public VideoListAdapter videoListAdapter;
String vid_id, vid_title, vid_type, vid_path, vid_img;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
initializeToolbar();
listView = (ListView) findViewById(R.id.listview_video);
videoArrayList = new ArrayList<Video>();
videoListAdapter = new VideoListAdapter(VideoActivity.this, videoArrayList);
jsonParser = new JSONParser();
new VideoTask().execute();
public class VideoTask extends AsyncTask<String, String, JSONObject> {
#Override
protected JSONObject doInBackground(String... strings) {
jsonObject = jsonParser.makeHttpRequest2(Network_constants.video_list_page, "POST");
Log.e("json data", "" + jsonObject);
return jsonObject;
}
#Override
protected void onPostExecute(JSONObject jsonObject) {
super.onPostExecute(jsonObject);
progressDialog.dismiss();
if (jsonObject != null) {
try {
jsonArray = jsonObject.getJSONArray("videos");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject1 = jsonArray.getJSONObject(i);
Log.d("jsonObject1", "" + jsonObject1);
Video video = new Video();
vid_id = jsonObject1.getString("video_id");
vid_title = jsonObject1.getString("video_channel_name");
vid_type = jsonObject1.getString("video_channel_link");
vid_path = jsonObject1.getString("video_channel_description");
vid_img = jsonObject1.getString("video_img_path");
video.set_vTitle(vid_title);
TextView t1 = (TextView) findViewById(R.id.video_title);
TextView t2 = (TextView) findViewById(R.id.video_type);
video.set_vArtist(vid_title);
video.set_vType(vid_type);
videoArrayList.add(video);
}
} catch (JSONException e) {
e.printStackTrace();
}
listView.setAdapter(videoListAdapter);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView cnt = (TextView) view.findViewById(R.id.video_type);
String cn = cnt.getText().toString();
Intent i = new Intent(VideoActivity.this, Youtube.class);
i.putExtra("url", cn);
startActivity(i);
}
});
}
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.clear();
getMenuInflater().inflate(R.menu.main,menu);
MenuItem menuItem = menu.findItem(R.id.menu_search);
final SearchView searchView = (SearchView) menuItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
if(TextUtils.isEmpty(newText)){
LogHelper.e("Query Result","Filter is Empty");
}else{
videoListAdapter.filter(newText);
}
return true;
}
});
return true;
}
}
And this is my CustomAdapter class :
public class VideoListAdapter extends BaseAdapter {
private Activity activity;
private static LayoutInflater inflater = null;
ImageView imageView;
private String mCurrentArtUrl;
private ArrayList<Video> video;
private ArrayList<Video> searchListView = null;
public VideoListAdapter(Activity a, ArrayList<Video> b){
this.activity = a;
this.video = b;
this.searchListView = new ArrayList<Video>();
this.searchListView.addAll(video);
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return video.size();
}
#Override
public Object getItem(int position) {
return video.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.video_list_item, null);
final TextView v_title = (TextView)vi.findViewById(R.id.video_title);
final TextView v_type = (TextView)vi.findViewById(R.id.video_type);
final TextView v_artist = (TextView)vi.findViewById(R.id.video_artist);
imageView = (ImageView) vi.findViewById(R.id.video_image);
Video video1 = video.get(position);
v_title.setText(video1.get_vTitle());
v_type.setText(video1.get_vType());
v_artist.setText(video1.get_vArtist());
String img = video1.get_vImage();
String profile = Network_constants.image_url + img;
fetchImageAsync(profile);
return vi;
}
// Filter method
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
video.clear();
if(charText.length() == 0){
video.addAll(searchListView);
}else{
for(Video v : searchListView){
LogHelper.e("Query","Entered For Loop");
if(v.get_vTitle().contains(charText)){
video.add(v);
}else{
LogHelper.e("Query","Could not create list");
}
}
}
notifyDataSetChanged();
}
}
I think my code is not working with the for loop in the filter function i guess.

You should implements Filterable in your Adapter

Image not match item in listview when search with SearchView Android

I have listview in fragment populated from Activity with bundle , i have custom baseadapter and custom object with image and text , listview work fine with image and text , but when i do search with searchview i can get text and it's position and onclicklistener is ok without any problem, the issue is that i can't have image(logos ) with the correcte item(texttitle) , images is ranged by it's own position and not item text position
First here is my Custom object
public class Channel {
public String name;
public String logoUrl;
public Channel(String name, String logoUrl) {
this.name = name;
this.logoUrl = logoUrl;
}
#Override
public String toString() {
return "Channel {" +
"name='" + name + '\'' +
", logoUrl='" + logoUrl + '\'' +
'}';
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getLogoUrl() {
return logoUrl;
}
public void setLogoUrl(String logoUrl) {
this.logoUrl = logoUrl;
}
}
and here is my custom Base Adapter
public class ChannelAdapter extends BaseAdapter implements Filterable{
private Activity context;
private ArrayList<Channel> channelNames = new ArrayList<>(); //mList
private ArrayList<Channel> channelLogos = new ArrayList<>();
private ArrayList<Channel> tmpNames= null;
private ArrayList<Channel> tmpLogos= null;
private CustomFilter myFilter = new CustomFilter();
ColorSpace.Model model;
public ChannelAdapter(Context context, ArrayList<Channel> channels, ArrayList<Channel> logos){
this.context = (Activity) context;
this.channelNames = channels;
this.channelLogos = logos;
this.tmpNames = channels;
this.tmpLogos = logos;
// Names.addAll(channelLogos);
}
#Override
public int getCount() {
// return Names.size();
return tmpNames.size();
}
#Override
public String getItem(int position) {
return String.valueOf(tmpNames.get(position));
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row =null;
if(convertView==null) {
LayoutInflater inflater=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row=inflater.inflate(R.layout.custom_row,parent, Boolean.parseBoolean(null));
}else{
row=convertView;
}
TextView textView= (TextView) row.findViewById(R.id.textv);
ImageView image=(ImageView) row.findViewById(R.id.imageView);
textView.setText((CharSequence) tmpNames.get(position));
Picasso.with(context)
.load(String.valueOf(tmpLogos.get(position)))
.into(image);
return row;
}
#Override
public Filter getFilter() {
if (myFilter == null) {
myFilter = new CustomFilter();
}
return myFilter;
}
public class CustomFilter extends Filter{
#Override
protected FilterResults performFiltering(CharSequence constraint) {
// TODO Auto-generated method stub
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
final ArrayList<Channel> list = channelNames; //remettre channelNames
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = String.valueOf(list.get(i));
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
return results;
}
#Override
protected void publishResults(CharSequence constraint,FilterResults results) {
// TODO Auto-generated method stub
// Names.clear();
// addAll((List<Channel>) results.values);
tmpNames = (ArrayList<Channel>) results.values;
notifyDataSetChanged();
}
}
}
and finaly my OnqueryTextChange
#Override
public boolean onQueryTextChange(String newText) {
((ChannelAdapter)listView.getAdapter()).getFilter().filter(newText.toString());
}
});

Have you tried using android:completionThreshold="1" inside AutoCompleteTextView?
or called mAutoCompleteTextView.setThreshold(1) to AutoCompleteTextView reference?

mAutoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);
Set your AutoCompleteTextView with Custom Adapter
mAutoCompleteTextView.setSelection(0);
mCustomAutoFilterAdapter = new CustomAutoFilterAdapter(this,R.layout.spinner_row, yourList);
mAutoCompleteTextView.setThreshold(1);
mAutoCompleteTextView.setAdapter(mCustomAutoFilterAdapter);
In your Custom Adapter Class include
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(viewResourceId, null);
}
return v;
}
#Override
public Filter getFilter() {

Android get data from Listview and show in a new activity

I am new to Android. I called lv.setOnItemClickListener to pick a selected item from ListView and show the data in a new activity through a new intent. But I don't know the could to do this works. I need some help.
MainActivity
public class MainActivity extends Activity implements
SearchView.OnQueryTextListener {
ListView lv;

country_flags = getResources().obtainTypedArray(R.array.country_flags);
countrylist = new ArrayList<Country>();
for (int i = 0; i < country_names.length; i++) {
Country country = new Country(country_names[i], iso_codes[i],
country_flags.getResourceId(i, -1));
countrylist.add(country);
}
adapter = new CustomAdapter(getApplicationContext(), countrylist);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener(){

Intent intent=new Intent(getActivity(),StartAnotherActitivity.class);
intent.putExtra(key,value);
startActivity(intent);
http://developer.android.com/reference/android/content/Intent.html

Here are the steps.
Get the position of the item clicked: This value will be passed to the method onItemClick
Now put this value as an Intent extra when you try to start the next activity
Read the index of the clicked item from your next Activity
Fetch the contents of the detail activity

Intent intent = new Intent(MainActivity.this,NewActivity.class);
intent.putExtra("Counttry",countrylist.get(arg2));
startActivity(intent);

Loading the filtered items to search output

I have implement search for my application. For that I have used an adapter as well. I have loaded 30 items to the search screen. When I pressed letter z to search, then letter z belongs to 4 items out of 30 items in the list.
According to the below shown code it identifies the number 4 and shows the first 4 items out of the 30 items. When I debug inside getFilter(), it shows the filtered items correctly(I have provided a screen shot).
My problem is how can I load the filtered items. Bit confused here.
search.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search_results_activity);

#Override

System.out.println("Text ["+s+"]");
adapter.getFilter().filter(s.toString());
TextView headerTV = (TextView) findViewById(R.id.search_header);
headerTV.setText("SEARCH RESULTS");

Screen shot

To filter adapter that contains list of custom object
Create a Object:
public class TvObject {
String name;
String description;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
After:
public class CustomListSearch extends BaseAdapter implements Filterable {
private Context context;
private ItemFilter mFilter = new ItemFilter();
private LayoutInflater mInflater;
private List<TvObject> mListTvObject = new ArrayList<>();
private List<TvObject> mListTvObjectFiltered = new ArrayList<>();
public CustomListSearch(Context c, List<TvObject> mListTvObject) {
this.context = c;
mInflater = LayoutInflater.from(context);
this.mListTvObject = mListTvObject;
this.mListTvObjectFiltered = mListTvObject;
}
#Override
public int getCount() {
return mListTvObjectFiltered.size();
}
#Override
public Object getItem(int position) {
return mListTvObjectFiltered.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
private class ViewHolder {
private TextView tvMenudescriptions;
private TextView tvDescriptions;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.search_list_item, parent, false);
holder.tvDescriptions = (TextView) convertView.findViewById(R.id.product_name);
holder.tvMenudescriptions = (TextView) convertView.findViewById(R.id.product_description);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.tvDescriptions.setText(mListTvObjectFiltered.get(position).getName());
holder.tvMenudescriptions.setText(mListTvObjectFiltered.get(position).getDescription());
LinearLayout itemlist = (LinearLayout) convertView.findViewById(R.id.product_lv);
itemlist.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, "Still under constructions...",Toast.LENGTH_LONG).show();
}
});
return convertView;
}
#Override
public Filter getFilter() {
return mFilter;
}
private class ItemFilter extends Filter {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
int count = mListTvObject.size();
final ArrayList<TvObject> mListResult = new ArrayList<>();
String name;
for (int i = 0; i < count; i++) {
TvObject mTvObject = mListTvObject.get(i);
name = mTvObject.getName();
if (name.toLowerCase().contains(filterString)) {
mListResult.add(mTvObject);
}
}
results.values = mListResult;
results.count = mListResult.size();
return results;
}
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint, Filter.FilterResults results) {
mListTvObjectFiltered = (ArrayList<TvObject>) results.values;
notifyDataSetChanged();
}
}
}
Edited:
In your Activity do something like this!
try {
final List<TvObject > mListObjects = new ArrayList<>();
for (int i = 0; i < responseJson.length(); ++i) {
final JSONObject object = responseJson.getJSONObject(i);
if ((object.getString("MainCategoryID")).equals("1")
&& (object.getString("SubCategoryID")).equals("1")
&& (object.getString("Visible")).equals("true")) {
Log.i("descriptionsTop ", object.getString("Description"));
Log.i("MenuDescription ", object.getString("MenuDescription"));
TvObject mTvObject = new TvObject();
mTvObject.setName(object.getString("Description"));
mTvObject.setDescription(object.getString("MenuDescription"));
mListObjects.add(mTvObject);
}
adapter = new CustomListSearch( getApplicationContext(), mListObjects);
lv.setAdapter(adapter);
}
} catch (JSONException e) {
e.printStackTrace();
