借助开源项目viewbadger：

github地址：https://github.com/jgilfelt/android-viewbadger

效果图：

 

添加数字：

BadgeView badgeView = new BadgeView(MainActivity.this, iv1);   

 badgeView.setText("5");
 badgeView.show();

添加文字：

          BadgeView badgeView = new BadgeView(MainActivity.this, iv2);
          badgeView.setText("新消息");
          badgeView.setTextSize(8.5f);
          badgeView.setTextColor(Color.DKGRAY);
          badgeView.show();

添加特定图标：

          BadgeView badgeView2 = new BadgeView(MainActivity.this, iv3);

          badgeView2.setBackgroundResource(R.drawable.noread);
          badgeView2.show();

去掉隐藏图标数字：

                badgeView.setVisibility(View.GONE);

 BadgeView badgeView2 = new BadgeView(MainActivity.this, iv3);          badgeView2.setBackgroundResource(R.drawable.noread);          badgeView2.show();
