请问一下如何做到在RadioGroup 中的 RadioButton右上角多加一个数字提醒呢？类似微信的底部导航一样。
最好能有例子。网络上的和我这个相差太大了，修改的时候也很复杂！谢谢了啊



               <RadioGroup

                    android:id="@+id/tab_radiogroup"

                    android:layout_width="fill_parent"

                    android:layout_height="wrap_content"

                    android:layout_gravity="bottom"

                    android:gravity="center_vertical"

                    android:orientation="horizontal" >



                    <RadioButton

                        android:id="@+id/fragment_radio1"

                        style="@style/tab_style"

                        android:layout_marginTop="2.0dip"

                        android:drawableTop="@xml/main_tabbar1"

                        android:text="@string/str_tab_title_home" />



                    <RadioButton

                        android:text="@string/str_tab_title_setting" />

                </RadioGroup>



	private void change_Fragment() {
