改变默认RadioButton的样式，结合<shape></shape> 和<selector ></selector>自定义drawable，通过设置android:button="@null" android:background="@drawable/bg_test或者android:button="@drawable/bg_front_size_12sp"

<RadioGroup
            android:id="@+id/lrc_frontSize"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:orientation="horizontal">

             //1.自定义drawable，直接设置android:button=" "
            <RadioButton
                android:id="@+id/a12"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="@dimen/dp_18"
                android:layout_marginRight="@dimen/dp_18"
                android:button="@drawable/bg_front_size_12sp" />

             //2.自定义drawable，设置android:button="@null " 然后设置 android:background=""
            <RadioButton
                android:id="@+id/a12"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="@dimen/dp_18"
                android:layout_marginRight="@dimen/dp_18"
                android:background="@drawable/bg_test
                android:button="@null"/>

        </RadioGroup>

    </LinearLayout>
