下面这种效果:
Badge 用法很简但 见下面的demo:
/**
* Created by Fangchao on 2015/2/25.
*/
@EActivity(R.layout.activity_usercenter)
public class UserCenterActivity extends BaseActionBarActivity implements DataHelper.DataListener {
@ViewById(R.id.person_detail_headImage)
CircleImageView headImageV;// 头像
@ViewById(R.id.person_detail_name)
TextView nameV;// 会员账户
@ViewById(R.id.person_detail_level)
ImageView levelV;
@ViewById(R.id.person_detail_price)
TextView priceV;// 账户余额
}
代码跳着看就行,懒得往外摘了
