onQueryTextSubmit call twice

I try to use seacrhview supported by ActionBarSherlock, but encount problem unexpected。 After i set OnQueryTextListener ,it call OnQueryTextListener twice in ZTE930 and samsung note2 but work fine in my moto! I also try the fix :

• if (event.getAction() == KeyEvent.ACTION_UP) {
• 复制

           onSubmitQuery();

• 复制

           return true;

• 复制

        }

• 复制

        return false;
  

  but it never call onQueryTextSubmit again! I don't kown why! Is there anyone help me? Thanks!
