由于Key有Down和Up事件，所以会执行两次。

class editTextOnKeyClickListener implements etOnKeyClickListener {

        @Override
        public boolean onKeyClick(View v, int keyCode, KeyEvent event) {
            // TODO Auto-generated method stub
            if (keyCode == KeyEvent.KEYCODE_ENTER&& event.getAction() == KeyEvent.ACTION_DOWN) {
                InputMethodManager imm = (InputMethodManager) v.getContext()
                        .getSystemService(Context.INPUT_METHOD_SERVICE);
                key = search_edit_text.getText().toString();
                if (imm.isActive()) {

                    imm.hideSoftInputFromWindow(v.getApplicationWindowToken(),
                            0);

                }
                load_view.setVisibility(View.VISIBLE);
                page = 0;
                SearchBookAsyncTask task = new SearchBookAsyncTask(key,
                        load_view, view, myBookList, search_book_adapter, page,
                        null, null, 0, list, showList,bg);
                task.execute();

            }

            return false;
        }
    }
