Creating a text filter (like quick search) for a Spinner in Android

Question

I\'m developing an Android application. I have my activity here with some widgets including a Spinner. I want that Spinner object to be searchable using the quick search but

Answer 1

I know this question is old, but today i also needed this function, and because I wasn´t able to find anything, i made myself a adapter for those spinner

The Adapter:

public class Searchspinner extends ArrayAdapter {
    private LayoutInflater inflater;
    private boolean dropdown = false;
    private OnClickListener onsearch;
    private ActionBar ab;
    private final ArrayList result = new ArrayList();
    private InputMethodManager keyboard;
    private boolean searching = false;
    public Searchspinner(Context context, int resource,
            ArrayList objects, LayoutInflater l, ActionBar a,
            InputMethodManager imm, String spinnerid) {
        super(context, resource, objects);
        inflater = l;
        ab = a;
        keyboard = imm; 
        createSearch();
        // TODO Auto-generated constructor stub
    }
    @Override
    public View getDropDownView(int position, View cnvtView, ViewGroup prnt{
        dropdown = true;
        return getCustomView(position, cnvtView, prnt);
    }
    @Override
    public View getView(int pos, View cnvtView, ViewGroup prnt) {
        dropdown = false;
        return getCustomView(pos, cnvtView, prnt);
    }
    public View getCustomView(int position, View convertView, ViewGroup     parent) {
        if (!dropdown) {
            View mySpinner = inflater.inflate(
                    R.layout.spinner_ressource_search, parent, false);
            TextView main_text = (TextView) mySpinner
                    .findViewById(R.id.tv_spinner_first);
            main_text.setText(getItem(position));
            ImageButton search = (ImageButton) mySpinner
                    .findViewById(R.id.searchbutton);
            if (!searching) {
                search.setImageResource(R.drawable.search);
            } else {
                search.setImageResource(R.drawable.search_check);
            }
            search.setOnClickListener(onsearch);
            return mySpinner;
        }
        View mySpinner = inflater.inflate(R.layout.auftragtextview, parent,
                false);
        TextView sub_text = (TextView)  mySpinner.findViewById(R.id.TextView01);
        sub_text.setText(getItem(position));
        return mySpinner;
    }
    private void createSearch() {
        onsearch = new OnClickListener() {
            @Override
            public void onClick(View v) {       
                // TODO Auto-generated method stub
                if (searching) {
                    searching = false;
                    ab.setCustomView(R.layout.actionbar_layout);
                    ab.getCustomView().setTag("0");
                    keyboard.toggleSoftInput(0,
                            InputMethodManager.HIDE_IMPLICIT_ONLY);
                    for (int i = 0; i < result.size(); i++) {
                        add(result.get(i));
                        result.remove(i);
                        i--;
                    }
                    ((ImageButton)  v).setImageResource(R.drawable.search);
                    return;
                }
                ((ImageButton)  v).setImageResouce(R.drawable.search_check);
                searching = true;
                ab.setCustomView(R.layout.searchable);
                final EditText et = (EditText) ab.getCustomView()
                        .findViewById(R.id.editText1);
                et.setActivated(true);
                    keyboard.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT,
                        0);
                et.requestFocus();
                et.addTextChangedListener(new TextWatcher() {
                    @Override
                    public void onTextChanged(CharSequence s, int start,
                            int before, int count) {
                        for (int i = 0; i < getCount(); i++) {
                            if (!getItem(i).contains(s)) {
                                result.add(getItem(i));
                                remove(getItem(i));
                                i--;
                            }
                        }
                        for (int i = 0; i < result.size(); i++) {
                            if (result.get(i).toLowerCase()
                                        .contains(s.toString().toLowerCase())) {
                                add(result.get(i));
                                result.remove(i);
                                i--;
                            }
                        }
                    }
                    @Override
                    public void beforeTextChanged(CharSequence s,
                            int start, int count, int after) {
                        // TODO Auto-generated method stub
                    }
                    @Override
                    public void afterTextChanged(Editable s) {
                        // TODO Auto-generated method stub
                    }
                });
            }
        };
    }
}

The spinner_ressource_search.xml:

and the auftragtextview.xml:

and this is how you create the Adapter:

Searchspinner auftragSpinnerAdapter = new Searchspinner(
    this.getApplicationContext(),
    R.layout.auftragtextview,
    list_auftragSpinner,getLayoutInflater(),
    getActionBar(),
    (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)
);  

I hope this is going to help anybody, and that i haven´t missed a already build in way to do this :D
Greetings

Edit:

The searcheble.xml

So the EditText1 is just a simple editText in The View that get´s in the Actionbar when you search.

The ActionbarLayout is the normal ActionbarView.
