Fragment如何实现下面Tab图标的小气泡？

Question

我用Fragment动态加载的方法
public class MainActivity extends FragmentActivity {

tabHost = (TabHost) findViewById(android.R.id.tabhost);
tabWidget = (TabWidget) findViewById(android.R.id.tabs);
LinearLayout layout = (LinearLayout)tabHost.getChildAt(0);
TabWidget tw = (TabWidget)layout.getChildAt(1);

     tabIndicator1 = (LinearLayout) LayoutInflater.from(this)
            .inflate(R.layout.tab_indicator, tw, false);
     TextView tvTab1 = (TextView)tabIndicator1.getChildAt(1);
     ImageView ivTab1 = (ImageView)tabIndicator1.getChildAt(0);
     ivTab1.setBackgroundResource(R.drawable.selector_mood_home);
     tvTab1.setText(R.string.buttom_home);

}
请问如何实现 ImageView ivTab1 冒小气泡（类似购物车上红色的小数字）的效果？

没图，不知道你指哪个。不过小数字一般都用BadgeView，基本够用了。
