覆盖搜索视图明文按钮

Question

当用户按下出现在搜索视图的文本视图末尾的十字并清除搜索查询时，我想覆盖默认操作。

我想清除搜索查询并打开另一个活动。

我怎样才能覆盖它？

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu items for use in the action bar
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.country_list_activity_actions, menu);
    mSearchMenu = menu.findItem(R.id.action_search);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        // Get the SearchView and set the searchable configuration
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        mSearchView = (SearchView) menu.findItem(R.id.action_search).getActionView();

        // Assumes current activity is the searchable activity
        mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        mSearchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default

        // Get the search close button image view
        ImageView closeButton = (ImageView)mSearchView.findViewById(R.id.search_close_btn);

        // Set on click listener
        closeButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                LoggerUtils.d(LOG, "Search close button clicked");
                //Find EditText view
                EditText et = (EditText) findViewById(R.id.search_src_text);

                //Clear the text from EditText view
                et.setText("");

                //Clear query
                mSearchView.setQuery("", false);
                //Collapse the action view
                mSearchView.onActionViewCollapsed();
                //Collapse the search widget
                mSearchMenu.collapseActionView();
            }
       });
    }

    // When using the support library, the setOnActionExpandListener() method is
    // static and accepts the MenuItem object as an argument
    mSearchMenu.setOnActionExpandListener(new OnActionExpandListener() {

        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            //Nothing to do here
            LoggerUtils.d(LOG, "Search widget expand ");
            return true; // Return true to expand action view
        }

        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            LoggerUtils.d(LOG, "Search widget collapsed ");
            return true; // Return true to collapse action view
        }
    });

    return super.onCreateOptionsMenu(menu);
