Question

<RelativeLayout          android:id="@+id/layout1"         android:layout_width="wrap_content"         android:layout_height="wrap_content">     <RadioGroup         android:id="@+id/radioGroup1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"          android:orientation="horizontal"         android:layout_alignParentBottom="true"         >         <RadioButton             android:id="@+id/radio0"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:checked="true"             android:text="@string/content1"              android:layout_weight="1"            android:drawableTop="@drawable/ic_launcher"           android:gravity="center_horizontal"             />         <RadioButton             android:id="@+id/radio1"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="@string/content2"              android:layout_weight="1"             android:drawableTop="@drawable/ic_launcher"             android:gravity="center_horizontal"/>         <RadioButton             android:id="@+id/radio2"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="@string/content3"              android:layout_weight="1"             android:gravity="center_horizontal"             android:drawableTop="@drawable/ic_launcher"             />         <RadioButton             android:id="@+id/radio3"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="@string/content4"              android:layout_weight="1"             android:gravity="center_horizontal"             android:drawableTop="@drawable/ic_launcher"            />     </RadioGroup> </RelativeLayout这样底部能平均分部，但是，只要给每一个radiobutton加上   button=“@null”的属性后就会变成我想要它们能平均分部在底部。。！求大神指教！
