活动代码

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.fun_handler_search_menu, menu); 
    // Associate searchable configuration with the SearchView 
    SearchManager searchManager = 
      (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
    SearchView searchView = 
      (SearchView) menu.findItem(R.id.action_search).getActionView(); 

    MenuItem searchMenuItem = menu.findItem(R.id.action_search); 
    searchMenuItem.expandActionView(); 

    searchView.setSearchableInfo(
      searchManager.getSearchableInfo(getComponentName())); 

    searchView.setSubmitButtonEnabled(true); 
    searchView.setOnQueryTextListener(this); 

    try { 
     ((EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text)).setHintTextColor(getResources().getColor(R.color.action_bar_grey_color)); 
     ((EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text)).setTextColor(getResources().getColor(R.color.action_bar_text_grey_color)); 

    } catch (Resources.NotFoundException e) { 
     e.printStackTrace(); 
    } 

    try { 
     ImageView searchClose = (ImageView) searchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn); 
     searchClose.setImageResource(R.drawable.ic_clear_24dp); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

    MenuItemCompat.setOnActionExpandListener(searchMenuItem, new MenuItemCompat.OnActionExpandListener() { 
     @Override 
     public boolean onMenuItemActionExpand(MenuItem item) { 
      return true; 
     } 

     @Override

      finish(); 
      overridePendingTransition(R.anim.slide_right_in, R.anim.slide_right_out); 
      return true;
