When I opened the searched item, it is opening the first item of ListView not the searched one. Even if search and find the items successfuly

When I opened the searched item, it is opening the first item of ListView not the searched one. Even if search and find the items successfuly.
I configure the adapter with "implements Filterable" and enable Listview with ".setTextFilterEnabled(true)", but doesn´t work.
I saw that I must implement "public Filter getFilter()" but I have no idea how can I do that.
When I type some words in EditText, like "cel" or "12" the filter goes in action, but the result is always the same: The first two items in Listview, no matter what is into the Listview (the content of listview is random).

What is missing?

I improved your adapter, didn't test it but it should work... I think it's easier to forward the Song list than the lists for each field separately... You have the original list for filtering and filteredList for adapter views...
EDITED: You have to implement Filterable, sorry i didnt see this...
public class ListAdapter extends BaseAdapter implements Filterable {
private final Context context;
private final List<Song> songlist;
private final List<Song> filteredList;
public ListAdapter(Context context, List<Song> songlist) {
this.context = context;
this.songlist = songlist;
filteredList = new ArrayList<>();
filteredList.addAll(songlist);
}
#Override
public int getCount() {
return filteredList.size();
}
#Override
public Object getItem(int i) {
return filteredList.get(i); // return Song item
}
#Override
public long getItemId(int i) {
return i; //TODO change this to return song id
}
#SuppressLint({"InflateParams", "ViewHolder"})
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
final ViewHolder viewHolder;
if (view == null) {
view = LayoutInflater.from(context).inflate(R.layout.songs_list_layout, null);
viewHolder = new ViewHolder(view);
view.setTag(viewHolder);
}else {
viewHolder = (ViewHolder) view.getTag();
}
Transformation transformation = new RoundedTransformationBuilder()
.cornerRadiusDp(15)
.build();
Song song = filteredList.get(i);
Picasso.get().load(song.getImageUrl()).transform(transformation).into(viewHolder.thumbnail);
viewHolder.songName.setText(song.getSongName());
viewHolder.artistName.setText(song.getSongArtist());
viewHolder.songDuration.setText(song.getSongDuration());
return view;
}
#Override
public Filter getFilter() {
return new Filter() {
#Override
protected FilterResults performFiltering (CharSequence constraint) {
FilterResults results = new FilterResults();
if (songlist != null && constraint != null) {
filteredList.clear();
List<Song> newValues = new ArrayList<>();
for (Song song: songlist) {
if(constraint.length() == 0) {
newValues.add(song); //TODO change this if you want empty list
}else{
if(song.getSongName.toLowerCase().contains(constraint.toString().toLowerCase())) {
newValues.add(song);
}
}
}
filteredList.addAll(newValues);
//filteredList = newValues;
results.count = newValues.size();
}
return results;
}
#Override
protected void publishResults (CharSequence constraint, FilterResults results) {
if (results != null && results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
};
}
private static class ViewHolder{
TextView songName;
TextView artistName;
TextView songDuration;
ImageView thumbnail;
CardView cardView;
ImageView currentlyPlaying;
ViewHolder(View view){
songName = view.findViewById(R.id.songName);
thumbnail = view.findViewById(R.id.songThumbnail);
artistName = view.findViewById(R.id.artistName);
songDuration = view.findViewById(R.id.songDuration);
cardView = view.findViewById(R.id.cardView);
currentlyPlaying = view.findViewById(R.id.currentlyPlaying);
}
}
}
and
public void retrieveSongs() {
DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference("Songs");
databaseReference.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot snapshot) {
List<Song> songsList = new ArrayList<>();
for (DataSnapshot ds : snapshot.getChildren()) {
Song song = ds.getValue(Song.class);
songsList.add(song);
jcAudios.add(JcAudio.createFromURL(song.getSongName(), song.getSongUrl()));
}
adapter = new ListAdapter(getApplicationContext(), songsList);
jcPlayerView.initPlaylist(jcAudios, null);
listView.setAdapter(adapter);
adapter.notifyDataSetChanged();
progressDialog.dismiss();
}
#Override
public void onCancelled(#NonNull DatabaseError error) {
Toast.makeText(MusicActivity.this, "FAILED!", Toast.LENGTH_SHORT).show();
}
});
}
Also its better to create one instance of adapter and swapData in retrieveSongs...
EDITED: Try something like this
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Song song = (Song)adapter.getItem(i)
jcPlayerView.playAudio(JcAudio.createFromURL(song.getSongName(), song.getSongUrl()));
jcPlayerView.setVisibility(View.VISIBLE);
jcPlayerView.createNotification();
adapter.notifyDataSetChanged();
}
});

I am not getting the videos in layout and even if try to select multiple items the items nothing happens in the activity.
Am I doing wrong?
I am using
gv.setChoiceMode(GridView.CHOICE_MODE_MULTIPLE_MODAL);
gv.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener()
but nothing happens.
Earlier I tried this to fetch the images from internal memory I get the desired result and able to select the items but in this, I am using the same logic to fetch videos and show in GridView layout but not getting the result.
I get black items as shown in the above screenshot and not able to select.
Please help me.

Displaying images using custom ListView Filter in Android

I have created a list view in android and implemented custom filtering method, but images in the list view are not corresponding to text after using filter. This is because it filters only namesList list. I need to filter both namesList and imagesList at the same time. How do I do that?
public class MyCustomList extends ArrayAdapter<String> implements Filterable {
private final Activity context;
private List<String> filterList;
private List<String> namesList;
private List<String> imagesList;
public CustomList(Activity context,List<String> namesList, List<String> imagesList) {
super(context, R.layout.list_single, namesList);
this.context = context;
this.namesList = namesList;
this.imagesList = imagesList;
this.filterList= namesList;
}
#Override
public int getCount(){
return namesList.size();
}
#Override
public String getItem(int pos){
return namesList.get(pos);
}
#Override
public long getItemId(int pos){
return namesList.indexOf(getItem(pos));
}
#Override
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View rowView= inflater.inflate(R.layout.list_single, null, true);
TextView txtTitle = (TextView) rowView.findViewById(R.id.txt);
ImageView imageView = (ImageView) rowView.findViewById(R.id.img);
txtTitle.setText(namesList.get(position));
imageView.setImageResource(context.getResources().getIdentifier(imagesList.get(position), "drawable", context.getPackageName()));
return rowView;
}
#Override
public Filter getFilter() {
Filter filter = new Filter() {
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
namesList = (List<String>) results.values;
notifyDataSetChanged();
}
#Override
protected FilterResults performFiltering(CharSequence constraint) {
namesList = filterList;
FilterResults results = new FilterResults();
if(constraint != null && constraint.length()>0){
List<String> FilteredArrayNames = new ArrayList <String>();
constraint = constraint.toString().toLowerCase();
for (int i = 0; i <namesList.size(); i++) {
String dataNames = namesList.get(i);
if (dataNames.toLowerCase().contains(constraint.toString())) {
FilteredArrayNames.add(dataNames);
}
}
results.count = FilteredArrayNames.size();
results.values = FilteredArrayNames;
Log.e("VALUES", results.values.toString());
} else {
results.count = namesList.size();
results.values = namesList;
}
return results;
}
};
return filter;
}
}

Modify your code with this:
List<String> FilteredArrayNames = new ArrayList <String>();
List<String> FilteredArrayImages = new ArrayList <String>();
constraint = constraint.toString().toLowerCase();
for (int i = 0; i <namesList.size(); i++) {
String dataNames = namesList.get(i);
String images = imagesList.get(i);
if (dataNames.toLowerCase().contains(constraint.toString())) {
FilteredArrayNames.add(dataNames);
FilteredArrayImages.add(images);
}
}
Then return this two List as a FilterResults object.

When i am bottom of the page and click on item it expands, but exapnded child item doesn't shows to user because it is bottom in the screen.
I want to move that item up in the screen and show expanded items to user.
How can i do that?

You can simply use the method setSelectedGroup()
expandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
#Override
public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
expandableListView.setSelectedGroup(groupPosition);
return true;
}
});
This will move the selected group to the top
EDIT
Finally I came out with a solution for your ExpandableRecyclerAdapter also. Simply put this method inside your adapter implementation. Also you will require the reference of the recyclerView inside the adapter which you can pass to the adapter at the time of initialization.
int lastPos = -1;
#Override
public void onParentListItemExpanded(int position) {
List<? extends ParentListItem> parentItemList = this.getParentItemList();
collapseAllParents();
int finalPos = position;
if (lastPos != -1 && lastPos < position) {
finalPos = position - parentItemList.get(lastPos).getChildItemList().size();
}
expandParent(finalPos);
mRecyclerView.smoothScrollToPosition(finalPos);
lastPos = position;
}
I found this issue at https://github.com/bignerdranch/expandable-recycler-view/issues/156 . Although the solution given there didn't work. Slight tweaking to that make it work.

Use this following code in your expandable listview click listener. Do something liket his
yourExpandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
#Override
public boolean onGroupClick(final ExpandableListView parent, View v, final int groupPosition, long id) {
....
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
parent.smoothScrollToPositionFromTop(groupPosition + 1, 0);
}
},100);
....
return true;
}
});

Use AnimatedExpandableListView

How to perform search in the expandable listview which is in the fragment?

Here is the thing..
I have one activity in which i have implmented the ActionBarSherlock,View Pager with Tab Navigation.
In Action Bar i have placed the search view.Now i am adding the list of fragments from the activity using viewPagerAdapter.
Now, In fragments i have placed the expandable listview and i am display the products with its section name in the expandable listview.

I am actually getting the action bar in wrong way.
TO use the action bar in each fragment ::
i have placed the setHasOptionsMenu(true); in my onCreate() of fragment
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
After that i am able to use the onCreateOptionMenu() in which i placed the searchview and now i am able to search the date from the expandable listview,getting text from searchview.
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.menu, menu);
final MenuItem searchItem = menu.findItem(R.id.menu_item_search);
final SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Search Here");
}
And now m done,Problem resolved.... ;)
