2.在Activity中

               FindButton find_great = (FindButton) mViewHolder.findViewById(R.id.find_great);  //获取控件的ID
find_great.setLeftButtonBg(R.drawable.faxian_zan);                                                      //  获取图片
find_great.setLeftButtonTextMessage("赞", 14, Color.parseColor("#949494"));       //获取图片右边的文字

                如果想让图片和文字只显示一个则调用

              setLeftButtonVisibly（int isVisibility）这个方法
