public class MainActivity extends Activity {

  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  searchIn = (EditText)findViewById(R.id.serchin);
  searchButton = (Button)findViewById(R.id.serch);
  searchOut = (ListView)findViewById(R.id.serchout);
  
  searchButton.setOnClickListener(searchButtonOnClickListener);
  
  geocoder = new Geocoder(this, Locale.ENGLISH);
  
  locationNameList = new ArrayList<String>(); //empty in start
  adapter = new ArrayAdapter<String>(this,
    android.R.layout.simple_spinner_item, locationNameList);
  searchOut.setAdapter(adapter);
 }
 
 OnClickListener searchButtonOnClickListener =
   new OnClickListener(){

    @Override
    public void onClick(View arg0) {
     String locationName = searchIn.getText().toString();
     
     Toast.makeText(getApplicationContext(), 
       "Search for: " + locationName, 
       Toast.LENGTH_SHORT).show();

      Toast.makeText(getApplicationContext(), 
        "locationName == null", 
        Toast.LENGTH_LONG).show();
     }else{
      try {
       locationList = geocoder.getFromLocationName(locationName, maxResults);
       
       if(locationList == null){
        Toast.makeText(getApplicationContext(), 
          "locationList == null",

        }else{
         Toast.makeText(getApplicationContext(), 
           "number of result: " + locationList.size(), 
           Toast.LENGTH_LONG).show();
         
         locationNameList.clear();
         
         for(Address i : locationList){
          if(i.getFeatureName() == null){
           locationNameList.add("unknown");
          }else{
           locationNameList.add(i.getFeatureName());
          }
         }
         
         adapter.notifyDataSetChanged();
        }
       }
       
       
      } catch (IOException e) {
       Toast.makeText(getApplicationContext(), 
         "network unavailable or any other I/O problem occurs" + locationName, 
         Toast.LENGTH_LONG).show();
       e.printStackTrace();
