How to use SearchView.OnQueryTextListener() in searchable spinner?

Question

I\'m creating a searchable spinner using third party library. I have added library classes(SearchableListDialog, SearchableSpinner) in my app. Everything is working fine but

Instead of using a Spinner with SearchView, I would suggest you to achieve this with ListView and SearchView, I tried and it works very well.

Put a button on your activity. Now clicking on this button will open a custom dialog.

Your custom_dialog.xml

Then set your button onClick event and do the following.

 @Override
            public void onClick(View view) {
                Dialog dialog = new Dialog(SearchText.this);
                LayoutInflater inflater = LayoutInflater.from(SearchText.this);
                View view1 = inflater.inflate(R.layout.custom_search_layout, null);
                ListView listView = view1.findViewById(R.id.listView);
                SearchView searchView = view1.findViewById(R.id.searchView);

                final ArrayAdapter stringArrayAdapter = new ArrayAdapter(SearchText.this, android.R.layout.simple_list_item_1, getResources().getStringArray(R.array.my_currency));
                listView.setAdapter(stringArrayAdapter);

                searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
                    @Override
                    public boolean onQueryTextSubmit(String newText) {
                        return false;
                    }

                    @Override
                    public boolean onQueryTextChange(String newText) {
                        stringArrayAdapter.getFilter().filter(newText);
                        return false;
                    }
                });
                dialog.setContentView(view1);
                dialog.show();
            }

Now do your search, and add OnItemClickListener on your listview, and do whatever you want after selecting your choice.
