How to implement search widget in Action Bar Sherlock?

Question

I tried to get Search box to work on Action Bar Sherlock.

This is my PreLocationActivity:

    @ContentView(R.layout.search)
    public class PreLocationActivity extends RoboSherlockActivity {

        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            //setContentView(R.layout.map_layout);
        } 

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            //Used to put dark icons on light action bar
             menu.add("Search")
             .setIcon(R.drawable.ic_search_inverse)
             .setActionView(R.layout.collapsible_edittext)
             .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
                return true;
        }

        @Override
        public boolean onSearchRequested() {
            return super.onSearchRequested();
        }
    }

This is my SearchableActivity:

@ContentView(R.layout.search)
public class SearchableActivity extends RoboSherlockFragmentActivity {

    @InjectView(R.id.addressListView) ListView addressView;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Get the intent, verify the action and get the query
        Intent intent = getIntent();
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
          String query = intent.getStringExtra(SearchManager.QUERY);
          doGeoSearch(query);
        }
}

    public void doGeoSearch(String query){
        Geocoder geocoder;
        ArrayList<Address> addresses;
        ArrayList<String> address = new ArrayList<String>() ;
        geocoder = new Geocoder(this, Locale.getDefault());
        try {
            addresses = (ArrayList<Address>) geocoder.getFromLocationName(query, 6);
            Log.d("Address",String.valueOf(addresses));
            for(int i = 0;i<addresses.size();i++)
            {
            String addr = new String();
            addr.concat(addresses.get(i).getAddressLine(0));
            addr.concat(addresses.get(i).getAddressLine(1));
            addr = addresses.get(i).getAddressLine(0) + addresses.get(i).getLocality() + addresses.get(i).getAdminArea();
            //addr.concat(addresses.get(i).getAddressLine(2));
            Log.d("addr",addr);
            address.add(addr);

            }

            SearchAddressAdapater addressList = new SearchAddressAdapater(getApplicationContext(),R.layout.search_list,addresses, SearchableActivity.this);
            addressView.setAdapter(addressList);
            //ListView addressListView = new ListView();
        } catch (IOException e) {
                //Handle exception
        }
    }

No success at all. As in, when I type something on the Prelocation Activity and press enter, nothing is being searched. Do I have to treat it as an EditText and write a text listener for that which then calls the geoCoder and gets me the locations or is there a smarter way to go about it?

Answer 1

private EditText search;

public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu)
{
    menu.add(0, 1, 1, R.string.menu_search).setIcon(R.drawable.ic_action_search).setActionView(R.layout.action_search).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item)
{
    switch (item.getItemId())
    {
        case 1:
        search = (EditText) item.getActionView();
        search.addTextChangedListener(filterTextWatcher);
        search.requestFocus();
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    }
}

private TextWatcher filterTextWatcher = new TextWatcher()
{
    public void afterTextChanged(Editable s)
    {
    }

    public void beforeTextChanged(CharSequence s, int start, int count, int after)
    {
    }

    public void onTextChanged(CharSequence s, int start, int before, int count)
    {
        // your search logic here
    }
};
