修改SearchView搜索框的下劃線.(或着其他屬性)

去掉當SearchView得到焦點時候出現的藍色背景線.

SearchView calSearchView = (SearchView)v.findViewById(R.id.calendar_search_view);

     if (calSearchView != null) {     

          try {        //--拿到字節碼      

              Class<?> argClass = calSearchView.getClass();      

                     //--指定某個私有屬性,mSearchPlate是搜索框父佈局的名字        

              Field ownField = argClass.getDeclaredField("mSearchPlate");    

                    //--暴力反射,只有暴力反射才能拿到私有屬性       

              ownField.setAccessible(true);       

              View mView = (View) ownField.get(calSearchView);

	            //--設置背景 

mView.setBackgroundColor(Color.TRANSPARENT);  

              }

         catch (Exception e) {       

               e.printStackTrace();   

              }}
