android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:button="@null"
android:drawablePadding="5dp"
android:drawableTop="@drawable/selector_yiwancheng"
android:gravity="center"
android:paddingTop="5dp"
android:text="已完成"
android:textColor="@color/selector_textcolor_wode"
android:textSize="14sp" />

BadgeView代碼：
BadgeView badgeView_yiwancheg = new BadgeView(getActivity());
badgeView_yiwancheg.setTargetView(radioButton_yiwancheng);
badgeView_yiwancheg.setBackgroundResource(R.drawable.informationcount);
badgeView_yiwancheg.setBadgeCount(1);
