Search Location on Action Bar Android - search

Question

I want to ask about finding a location using the action bar. I've made ​​the program as shown below :
I've made a class to find location. but at the time I called into the EditText search, class does not work.
// An AsyncTask class for accessing the GeoCoding Web Service
private class GeocoderTask extends AsyncTask<String, Void, List<Address>>{
#Override
protected List<Address> doInBackground(String... locationName) {
// Creating an instance of Geocoder class
Geocoder geocoder = new Geocoder(getBaseContext());
List<Address> addresses = null;
try {
// Getting a maximum of 3 Address that matches the input text
addresses = geocoder.getFromLocationName(locationName[0], 3);
} catch (IOException e) {
e.printStackTrace();
}
return addresses;
}
}
protected void onPostExecute(List<Address> addresses) {
if(addresses==null || addresses.size()==0){
Toast.makeText(getBaseContext(), "No Location found", Toast.LENGTH_SHORT).show();
}
// Clears all the existing markers on the map
map.clear();
// Adding Markers on Google Map for each matching address
for(int i=0;i<addresses.size();i++){
Address address = (Address) addresses.get(i);
// Creating an instance of GeoPoint, to display in Google Map
latLng = new LatLng(address.getLatitude(), address.getLongitude());
String addressText = String.format("%s, %s",
address.getMaxAddressLineIndex() > 0 ? address.getAddressLine(0) : "",
address.getCountryName());
markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title(addressText);
map.addMarker(markerOptions);
// Locate the first location
if(i==0)
map.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng,10));
}
}
and I had to call the class to the class action bar menu. like this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.cost_direction, menu);
/** Get the action view of the menu item whose id is search */
View v = (View) menu.findItem(R.id.search).getActionView();
/** Get the edit text from the action view */
EditText txtSearch = ( EditText ) v.findViewById(R.id.txt_search);
/** Setting an action listener */
txtSearch.setOnEditorActionListener(new OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
// Getting user input location
String location = v.getText().toString();
if(location!=null && !location.equals("")){
new GeocoderTask().execute(location);
}
Toast.makeText(getBaseContext(), "Search : " + v.getText(), Toast.LENGTH_SHORT).show();
return false;
}
});
return super.onCreateOptionsMenu(menu);
}
please help for those who know about the problems I was having. :)

String strPlace = etSearch.getText().toString();
Geocoder gc = new Geocoder(getBaseContext(), Locale.getDefault());
List<Address> adrs = null;
try{
adrs = gc.getFromLocationName(strPlace,5);
}catch(IOException e){
}finally{
if (adrs != null){
if(adrs.size() > 0)
{
LatLng loc = new LatLng(adrs.get(0).getLatitude(), adrs.get(0).getLongitude());
map.moveCamera(CameraUpdateFactory.newLatLngZoom(loc, 15));
// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(13), 2000, null);
}
