nit: GetIcon -> icon, here and other accessors.

Sorry for not being clear in my previous comment. The naming in previous CL is
good. I only wanted to adjust the declaration order.

[Qiang(Joe) Xu, 2017/06/21 20:29:35]

Done.

   void SetIcon(const gfx::ImageSkia& icon);
+
+  views::ImageView* GetBadge() const { return badge_; }

If the badge is only used in SearchResultTitleItemView, is it better to move
this part as well as other badge related code to SearchResultTitleItemView?

[Qiang(Joe) Xu, 2017/06/21 19:07:13]

If we don't have badging requirement for suggested apps (it seems will not), we
should move it I think. Let us keep it first (as it is not a blocking need right
now).

[weidongg, 2017/06/21 19:45:33]

That makes sense.

   void SetBadgeIcon(const gfx::ImageSkia& badge_icon);
+
+  views::Label* GetTitle() const { return title_; }
   void SetTitle(const base::string16& title);
 
  private:
   void UpdateBackgroundColor();
