覆蓋searchview清除文本按鈕

Question

我想要覆蓋默認操作，當用戶按下十字會出現在searchview的textview的結尾處並清除搜索查詢。

我想清除搜索查詢以及打開另一個活動。

我怎麼能重寫呢？

       mSearchMenu.collapseActionView(); 
      } 
     }); 
    }

    // static and accepts the MenuItem object as an argument 
    mSearchMenu.setOnActionExpandListener(new OnActionExpandListener() { 

     @Override

      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);
