I'm trying to search through a ListView With the use of a TextView, after writing the code, it was Logging out what I did, but not filtering the List I want it to filter. Here is my code:
public class LabDetailActivity extends ActionBarActivity {
private LabAdapter labListAdapter;
private List<LabItem> labItem;
private TextView searchText;
private SearchView mSearchView;
private ListView list;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.assigned_lab_fragments);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Labs");
searchText = (TextView) findViewById(R.id.labText);
list = (ListView) findViewById(android.R.id.list);
labItem = new ArrayList<LabItem>();
labListAdapter = new LabAdapter(this, labItem);
list.setAdapter(labListAdapter);
list.setTextFilterEnabled(true);
list.setOnItemClickListener(new ListItemClickListener());
searchText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3) {
/*labListAdapter.getFilter().filter(charSequence.toString());
list.setAdapter(labListAdapter);*/
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i2, int i3) {
int textLength = charSequence.length();
List<LabItem> labItemss = new ArrayList<LabItem>();
for (LabItem ll : labItem){
if(textLength <= ll.getName().length()){
if (ll.getName().toLowerCase().contains(charSequence.toString().toLowerCase())){
labItemss.add(ll);
}
}
}
Log.d("SIZE OF SEARCH", String.valueOf(labItemss.size()));
labListAdapter = new LabAdapter(LabDetailActivity.this, labItemss);
list.setAdapter(labListAdapter);
}
#Override
public void afterTextChanged(Editable editable) {
/*Log.d("NEW TAGS", "*** Search value changed: " + editable.toString());
if (editable.toString().length() >= 3)
labListAdapter.getFilter().filter(editable.toString());*/
//labListAdapter.getFilter().filter(editable.toString());
//labListAdapter.notifyDataSetChanged();
}
});
}
private class ListItemClickListener implements ListView.OnItemClickListener{
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
}
}
private void RetrieveData(){
Uri uri2 = Uri.parse("content://" + getString(R.string.LEONE_AUTHORITY) + "/olabs");
Log.d("URL PRINT", uri2.toString());
final Cursor cursor = getContentResolver().query(uri2, null, null, null, "_id");
Log.d("CURSOR DATA:", cursor.toString());
JSONArray array = new JSONArray();
if (cursor != null && cursor.getCount() > 0) {
while (cursor.moveToNext()) {
JSONObject object = new JSONObject();
try {
object.put("lab_number", cursor.getString(cursor.getColumnIndex("lab_case_number")));
object.put("lab_name", cursor.getString(cursor.getColumnIndex("lab_case_name")));
array.put(object);
Log.d("ARRAY", String.valueOf(array.length()));
} catch (JSONException e) {
e.printStackTrace();
}
}
parseJsonLabs(array);
cursor.close();
}
}
private void parseJsonLabs(JSONArray array){
Log.d("CASESARRAY", array.toString());
try {
labItem.clear();
for (int i = 0; i < array.length(); i++) {
JSONObject cases = (JSONObject) array.get(i);
LabItem items = new LabItem();
items.setName(cases.getString("lab_number"));
items.setCase(cases.getString("lab_name"));
labItem.add(items);
}
labListAdapter.notifyDataSetChanged();
} catch (JSONException e) {
// TODO: handle exception
Log.e("ARRAYTEST", "ERROR:", e);
}
}
#Override
protected void onResume() {
super.onResume();
RetrieveData();
}
}
Then, the Adapter code is here
Adapter
public class LabAdapter extends BaseAdapter implements Filterable{
private Activity activity;
private LayoutInflater inflater;
private List<LabItem> labItem;
private TextView labName, labCase;
public LabAdapter(Activity activity, List<LabItem> labItem){
this.activity = activity;
this.labItem = labItem;
}
#Override
public int getCount() {
return labItem.size();
}
#Override
public Object getItem(int position) {
return labItem.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
if (inflater == null)
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.custom_lab_activity_list, null);
labName = (TextView) convertView.findViewById(R.id.custom_lab_name);
labCase = (TextView) convertView.findViewById(R.id.custom_lab_case);
LabItem labs = labItem.get(position);
labName.setText(labs.getName());
labCase.setText(labs.getCase());
return convertView;
}
#Override
public Filter getFilter() {
return new Filter() {
#Override
protected FilterResults performFiltering(CharSequence charSequence) {
Log.d("SEARCHTEXT2", "**** PERFORM FILTERING for: " + charSequence);
charSequence = charSequence.toString().toLowerCase();
FilterResults filts = new FilterResults();
if (charSequence == null || charSequence.length() == 0){
filts.values = labItem;
filts.count = labItem.size();
} else {
// We perform filtering operation
List<LabItem> labrs = new ArrayList<LabItem>();
for (LabItem l : labrs){
if (l.getName().startsWith(charSequence.toString()) || l.getCase().startsWith(charSequence.toString()))
labItem.add(l);
}
filts.values = labItem;
filts.count = labItem.size();
//filts.count = labItem.size();
}
return filts;
}
#Override
protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
// Now we have to inform the adapter about the new list filtered
Log.d("SEARCHTEXT1", "**** PUBLISHING RESULTS for: " + charSequence);
if (filterResults.count == 0)
notifyDataSetInvalidated();
else {
labItem = (List<LabItem>) filterResults.values;
notifyDataSetChanged();
}
}
};
}
public void notifyDataSetChanged(){
super.notifyDataSetChanged();
}
}
And the Item class is here
Item Class
public class LabItem {
String labCase, labName;
public LabItem() {
}
public LabItem(String labCase, String labName){
super();
this.labCase = labCase;
this.labName = labName;
}
public String getName(){
return labName;
}
public void setName(String name){
this.labName = name;
}
public String getCase(){
return labCase;
}
public void setCase(String cases){
this.labCase = cases;
}
}
I don't know if I'm not updating the ListView very well or something. When I type a i see the count, but If I add another letter. The LIST would be gone. Any help would be appreciated. Thanks in advance.
Few Logical Mistakes : I got here this code working at my end
public LabAdapter(Activity activity, List<LabItem> labItem){
this.activity = activity;
this.labItem = labItem;
}
#Override
public int getCount() {
return labItem.size();
}
#Override
public LabItem getItem(int position) { //instead of Object make it Labitem
return labItem.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
if (inflater == null)
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.activity_stack, null);
labName = (TextView) convertView.findViewById(R.id.textView1);
labCase = (TextView) convertView.findViewById(R.id.textView2);
LabItem labs = labItem.get(position);
labName.setText(labs.getName());
labCase.setText(labs.getCase());
return convertView;
}
#Override
public Filter getFilter() {
return new Filter() {
#Override
protected FilterResults performFiltering(CharSequence charSequence) {
Log.d("SEARCHTEXT2", "**** PERFORM FILTERING for: " + charSequence);
charSequence = charSequence.toString().toLowerCase();
FilterResults filts = new FilterResults();
if (charSequence == null || charSequence.length() == 0){
filts.values = labItem;
filts.count = labItem.size();
} else {
// We perform filtering operation
List<LabItem> labrs = new ArrayList<LabItem>();
for (LabItem l : labItem){ //you are going to search in labItem that contains the data and not the empty list labrs
if (l.getName().startsWith(charSequence.toString()) || l.getCase().startsWith(charSequence.toString())){
Log.e("(l.getName().startsWith(charSequence.toString())","" + charSequence);
labrs.add(l); // add to the new list**
}
}
filts.values = labrs; //set values to the new list**
filts.count = labrs.size();
//filts.count = labItem.size();
}
return filts;
}
#Override
protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
// Now we have to inform the adapter about the new list filtered
Log.d("SEARCHTEXT1", "**** PUBLISHING RESULTS for: " + charSequence);
List<LabItem> filtered = (List<LabItem>) filterResults.values;
labItem = filtered; // set the new data as you want with the new set you've received.**
notifyDataSetChanged();
}
};
}
public void notifyDataSetInvalidated()
{
super.notifyDataSetInvalidated();
}
then in your LabDetailActivity.class change it as
searchText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3) {
labListAdapter.getFilter().filter(charSequence.toString());
Log.d("NEW TAGS", "*** Search value changed: " + labListAdapter.getCount());
list.invalidate();
labListAdapter.notifyDataSetChanged();
list.setAdapter(labListAdapter);
}
Edit:
P.S. This code is still not perfect as after clearing the text it
doesn't sets the list back. I leave it to you. Hope this solves your
problem you've been facing.
Let me know if it works.

I have a problem with my custom filter. I make it, and it works well. When I debug code, it filtrates array well, but I have a problem in void publishResults(). I don't know what is a problem, anyone helps?

I was looking for an answer, and I found that in that function I need to put in array my data. I did it, but still not work.
i am provide recyler view adapter with filter for contact details and you can change code your need according.

and call into activity in edittext box for filter record like below ..
filter the data
Note: make sure your adapter object not null
/**

});
}
My problem was that in some line I hade gridView.setAdapter(null).
However, I had one more problem, in gridView I had 5 elements, after filtering, I had one item filled with real data and 4 more empty items.. So, I changed getView function..
If someone need it, here it is:
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
View v = convertView;
if(v==null) {
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.katalozi_item, null);
}
if(objectfilt.size()>position){
Katalog katalog = objectfilt.get(position);
ImageView katalogImage = (ImageView) v.findViewById(R.id.katalogImage);
TextView katalogProizvodjac = (TextView) v.findViewById(R.id.katalogProizvodjac);
TextView katalogVaziDo = (TextView) v.findViewById(R.id.katalogVaziDo);
TextView idKataloga = (TextView) v.findViewById(R.id.idKataloga);
String src = katalog.getImageSRC();
Picasso.with(getContext()).load(src).into(katalogImage);
/*Glide.with(getContext()).load(src).thumbnail(Glide.with(getContext()).load(R.drawable.loading_icon))
.fitCenter()
.crossFade().into(katalogImage); */
// katalogImage.setImageBitmap(bitmap);
katalogProizvodjac.setText(katalog.getKatalogProizvodjac());
String doe = katalog.getKatalogVaziDo();
char lastChar = doe.charAt(doe.length() - 1);
if(lastChar=='1'){
katalogVaziDo.setText("Važi još "+ doe +" dan");
}
if(doe.equals("0")){
katalogVaziDo.setText("Važi još danas");
}
if(lastChar!='1' && !doe.equals("0")){
katalogVaziDo.setText("Važi još "+katalog.getKatalogVaziDo() + " dana");
}
// katalogVaziDo.setText("Važi do: "+katalog.getKatalogVaziDo());
idKataloga.setText(String.valueOf(katalog.getIdKataloga()));
return v;
}
else {
v.setVisibility(View.GONE);
return v;
}
So, elements from ListArray objectfilt are added, and when int position become bigger than number of ListView elements, then just hide that views.
I have a listview getting filtered by an edit text on top.However when i click on the item searched i get the result of another item being selected. there r also some data stored in my array which is not visible on listview , is also returning wrong data.
On searching C you get the result filtered as C.But clicking on it results is like the position does not change for the other data but uses the original ArrayList adapter position.
Any help will be appreciated.

You have to ask the adapter to get the right object.
Instead of
Leave_master_items leave_master_items = leave_master_itemses.get(position);
try
Leave_master_items leave_master_items = listview_leave.getAdapter().getItem(position);
UPDATE
When you filter you don't have to create a new object with the same content. Just use the object which already exist.
Instead of
Leave_master_items country = new Leave_master_items(mStringFilterList.get(i).getLeave_Name());
filterList.add(country);
Do
filterList.add(mStringFilterList.get(i));
UPDATE2
Don't return 0 in getItemId()
#Override
public long getItemId(int position) {
return position;
}
The problem here is as soon as you start searching something in edittext, your list content changes and you might be using the old list to get the item.
Create a setter in your adapter class for the list you just got after filtering and use that list in your onItemCLick to fetch the position you want to fetch.
In my application I have three fragment with ViewPager. one of this fragments i have simple Arraylist as ListView from phones contact list and i'm trying to filter that after typing into edittext.
but doesn't refresh until softkeyboard is visible and I must have to hide keyboard to refresh list view by filtered strings.
For example:
filter listview by "a":
adapter.getFilter().filter("a");
My adapter:
public class AdapterContacts extends BaseAdapter implements Filterable {
private LayoutInflater inflater;
private Context context;
private List<ContactLists> categoryArrayList;
private final ArrayList<ContactLists> originalList = new ArrayList<ContactLists>();

ListView succesful filtered by when i close or hide softkeyboard that refresh with nw items.
You're not making use of your adapter filter as I see from the code posted by you. I'll post here an example filter and how to call it (kept all your variable names to make it easier).
The 'NameFilter' class, inside your adapter class:
public class NameFilter extends Filter {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
String searchText = constraint.toString().toLowerCase();
ArrayList<ContactLists> newList = filterListBasedOnSearchText(searchText);
results.values = newList;
results.count = newList.size();
return results;
}
private ArrayList<ContactLists> filterListBasedOnSearchText(String constraint) {
ArrayList<ContactLists> newList = new ArrayList<ContactLists>();
int l = originalList.size();
for (int i = 0; i < l; i++) {
ContactLists nameList = originalList.get(i);
if (nameList.getContact_name().toString().contains(constraint)) {
newList.add(nameList);
}
}
return newList;
}
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
categoryArrayList = (ArrayList<ContactLists>) results.values;
notifyDataSetChanged();
}
}
The 'TextWatcher' interface method implementation in your list fragment:
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
public void afterTextChanged(Editable s) {
String text = searchView.getText().toString();
NameFilter itemFilter = (NameFilter) adapter.getFilter();
itemFilter.filter(text);
}
Also, some observations:
if 'ContactLists' is a contact, name it 'Contact', to avoid confusion
I would use a 'SearchView', instead of an 'EditText'
I don't know how you get the contact list, but there's a guide about it here (if you didn't look at it already)
It is very simple to implement. Please follow these below steps:
Step 1:
Initialize Edittext:
editTextVideoFolderSearch = (EditText) rootView.findViewById(R.id.editTextVideoFolderSearch);
Step 2:
Add TextChangedListener on this edittext. like:
editTextVideoFolderSearch.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence t, int start, int before,
int count) {
videoDetailBeansSearch.clear();
for (int i = 0; i < videoDetailBeans_total.size(); i++) {
if (videoDetailBeans_total.get(i).getAlbum().toLowerCase()
.contains(t)) {
videoDetailBeansSearch.add(videoDetailBeans_total.get(i));
}
}
if (videoDetailBeansSearch.size() > 0) {
video_folder_gridView.setAdapter(new AlbumGridAdapter(getActivity(), videoDetailBeansSearch));
} else {
video_folder_gridView.setAdapter(new AlbumGridAdapter(getActivity(), videoDetailBeansSearch));
}
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void afterTextChanged(Editable s) {
}
});
Step 3: you have to make different beans for populating the adapter in list view:
private ArrayList<MediaDetailBean> videoDetailBeansSearch = new ArrayList<MediaDetailBean>();
private ArrayList<MediaDetailBean> videoDetailBeans_total = new ArrayList<MediaDetailBean>();
private ArrayList<MediaDetailBean> videoDetailBeans_delete = new ArrayList<MediaDetailBean>();
Step 4: Polulate the list at the time of Activity or fragment loaded:
public class GetVideoAsynctask extends AsyncTask<String, String,Object[]> {
ProgressDialog progressDialog ;
String response = "";
int offset, limit;
public GetVideoAsynctask(int offset1, int limit1) {
offset = offset1;
limit = limit1;
}
#Override
public void onPreExecute() {
progressDialog = ProgressDialog.show(getActivity(),"Loading...", "Please Wait");
}
#Override
public Object[] doInBackground(String... params) {
return AppParsing.getMediaDetails(getActivity(), AppPreferenceUtils.getChildUploadDeviceId(getActivity()),
AppPreferenceUtils.getChildRaId(getActivity()),"2", offset, limit,"3");
//// type=1 for image,2 for video,3 for audio
}
#SuppressWarnings("unchecked")
#Override
public void onPostExecute(Object[] result) {
progressDialog.cancel();
try
{
boolean status = (Boolean) result[0];
response = (String) result[1];
if(status)
{
videoDetailBeans = (ArrayList<MediaDetailBean>) result[2] ;
for (int i = 0; i < videoDetailBeans.size(); i++) {
videoDetailBeans_total.add(videoDetailBeans.get(i));
}
isCheck_video = new boolean[videoDetailBeans_total.size()];
for(int i=0;i<videoDetailBeans_total.size();i++)
{
if(!GRID_DATA.contains(videoDetailBeans_total.get(i).getAlbum()))
{
GRID_DATA.add(videoDetailBeans_total.get(i).getAlbum());
}
}
video_folder_gridView.setAdapter(new AlbumGridAdapter(getActivity(), videoDetailBeans_total));
//Toast.makeText(getActivity(), response, Toast.LENGTH_SHORT).show();
}
else
{
response = (String) result[1];
AppUtils.showDialog(getActivity(), response);
}
}
catch (Exception e) {
e.printStackTrace();
}
}
}
Step 5: Set the listview adapter like:
new GetVideoAsynctask(offset1, limit1).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
Step 6: Most important thinning is i am taking load more list view here:
com.costum.android.widget.LoadMoreListView) video_folder_gridView = (com.costum.android.widget.LoadMoreListView) rootView.findViewById(R.id.video_folder_gridView);
Step 7: In my xml i am declaring like this:
<com.costum.android.widget.LoadMoreListView
android:id="#+id/video_folder_gridView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnWidth="90dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:verticalSpacing="10dp" />
Feel free if you have any query regarding this concept.
This is my implementation of Filter which filters while you type a single letter.This is the Activity implementation...
public class MessagesActivity extends Activity{
private ListView msgListView;
private EditText mSearchContent;
private MessagesAdapter msgAdapter;
public static ArrayList<MessagesBean> allMsgsList = new ArrayList<MessagesBean>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_messages);
init();
msgAdapter = new MessagesAdapter(getApplicationContext(), allMsgsList, MessagesActivity.this);
msgListView.setAdapter(msgAdapter);
}
private void init() {
// TODO Auto-generated method stub
msgListView = (ListView) findViewById(R.id.messages_list);
msgListView.setOnScrollListener(this);
mSearchContent.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
}
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {

public void afterTextChanged(Editable s) {
msgAdapter.getFilter().filter(s.toString());

You can do it like:
public void filter(String charText) {
drinks.clear();
if (charText.length() == 0) {
drinks.addAll(contact_list);
} else {
for (ContactLists wp : contact_list) {
if (wp.getContact_name().contains(charText)) {
drinks.add(wp);
}
}
}
contact_list.clear();
contact_list.addAll(drinks);
adapter.notifyDataSetChanged(contact_list);
}
and in your adapter:
public void notifyDataSetChanged(List<ContactLists> items){
this.categoryArrayList = items;
super.notifyDataSetChanged();
}
I am using a custom adapter with a search filter in a fragment, however the results don't get filtered on a search, I debugged and stepped through my code and find that it is saying that the args.listenere = null!. What does this mean and how do I correct it? My code is below:

I have now resolved this, the issue was that I was creating a new instance of the adapter in the text watcher. Once I set it to use the adapter that created the original list then it worked fine
I have a problem in making suggestion in AutoCompleteTextView in this pattern
[action actionFromContact] (these are 2 adapter) ex call michael (where "call" comes from action adapter , "michael" from actionFromContact adapter these following code does first it set adapter in AutoCompleteTextView to item and when text changes to call it reset to contact db from name so its like call michael ,
Problem item array is too big so I can't use replace thing , second replacing remove the first entry when second entry i.e name is been selected from drop down menu as its been replaced by space
private AutoCompleteTextView mEditText;
private TextWatcher mTextWatcher;
private ContactPickerAdapter contactPickerAdapter;
String item[] = { "Call", "Call back"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mEditText = (WithSomeOneAutoCompleteTextView) findViewById(R.id.editTextTest);
contactPickerAdapter = new ContactPickerAdapter(this,
android.R.layout.simple_dropdown_item_1line,
ContactQuery.getContacts(this, false));
mEditText.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, item));
mTextWatcher = new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void afterTextChanged(Editable s) {
String t = s.toString().replace("call ",");
contactPickerAdapter.getFilter().filter(t);
if (s.toString().equalsIgnoreCase("call ")) {
Toast.makeText(MainActivity.this, "CALL",
Toast.LENGTH_SHORT).show();
mEditText.setAdapter(contactPickerAdapter);
}
if (s.toString().equalsIgnoreCase("Call back")) {
// t.replace("call back ", "");
// System.out.println("t is: " + t);
// contactPickerAdapter.getFilter().filter(t);
Toast.makeText(MainActivity.this, "Launch",

}
}

Still a bit unclear what are you trying to achieve.
Anyway.
Well as a first step I would attach the TextWatcher to the mEditText
mEditText.addTextChangedListener(mTextWatcher);
Then I would remove
contactPickerAdapter.getFilter().filter(t);
see how it goes.
I suggest that you post the code of your contactPickerAdapter as well.
