Answer 1

Thanks Mister Murakami for the idea, i have implemented the same concept to perform toggle search and as per my view its not a hack but its beauty of OOPs. Below program having a toggle icon in the action bar to switch between search hint.

1. RestaurantListingActivity.java

   public class RestaurantListingActivity extends BaseMainActivity implements
   TabListener {
   private boolean isRestaurantSearch = true;
   private SearchManager searchManager;
   private SearchView searchView;
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       ActionBar aBar = getActionBar();
       aBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
       aBar.addTab(aBar.newTab().setText("Place Order").setTabListener(this));
       aBar.addTab(aBar.newTab().setText("My Account").setTabListener(this));
       aBar.addTab(aBar.newTab().setText("Favorite").setTabListener(this));
       aBar.addTab(aBar.newTab().setText("Vendor Portal").setTabListener(this));
   }
   
   @Override
   public boolean onCreateOptionsMenu(Menu menu) {
       getMenuInflater().inflate(R.menu.restaturant_listing_menu, menu);
       searchManager = (SearchManager) getSystemService(SEARCH_SERVICE);
       searchView = (SearchView) menu.findItem(R.id.rlm_search)
               .getActionView();
       searchView.setSearchableInfo(searchManager
               .getSearchableInfo(new ComponentName(this,
                       RestaurantListingActivity.class)));
       return super.onCreateOptionsMenu(menu);
   }
   @Override
   public boolean onOptionsItemSelected(MenuItem item) {
       switch (item.getItemId()) {
       case R.id.rlm_toggle:
   isRestaurantSearch = !isRestaurantSearch;
       if (isRestaurantSearch)
           searchView.setSearchableInfo(searchManager
                   .getSearchableInfo(new ComponentName(this,
                           RestaurantListingActivity.class)));
       else
           searchView.setSearchableInfo(searchManager
                   .getSearchableInfo(new ComponentName(this,
                           RestaurantFoodSwitcherActivity.class)));
   
   
       break;
   case R.id.rlm_change_loc:
   
       break;
   case R.id.rlm_filter_search:
   
       break;
   }
   
       return super.onOptionsItemSelected(item);
   }
   
   @Override
   public void onTabReselected(Tab tab, FragmentTransaction ft) {
       // TODO Auto-generated method stub
   
   }
   
   @Override
   public void onTabSelected(Tab tab, FragmentTransaction ft) {
   // TODO Auto-generated method stub
   }
   
   @Override
   public void onTabUnselected(Tab tab, FragmentTransaction ft) {
       // TODO Auto-generated method stub
   
   }
   
   @Override
   public void setScreenData(Object screenData, int event, long time) {
       // TODO Auto-generated method stub
   
   }
   
   @Override
   public Activity getMyActivityReference() {
       // TODO Auto-generated method stub
       return null;
   }
   
   @Override
   public void onClick(View v) {
       // TODO Auto-generated method stub
   
   }
   }
