How to make 2 horizontal buttons to fill relative layout equally? - android-relativelayout

Question

the corresponding xml layout:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/buttons_holder"
android:layout_below="#+id/list_holder"
android:layout_alignParentBottom="true">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/previous_button"
android:src="#android:drawable/ic_media_previous"
android:layout_alignParentLeft="true"
android:minWidth="150dp"
android:layout_alignParentBottom="false"
android:layout_alignParentRight="false"
android:layout_alignParentTop="false"
android:scaleType="fitEnd" />
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/forward_button"
android:src="#android:drawable/ic_media_next"
android:layout_alignParentRight="true"
android:minWidth="150dp"
android:scaleType="fitStart"
android:layout_alignWithParentIfMissing="false" />
</RelativeLayout>
I can change button's width just by setting
minWidth = 200dp
maxWidth = 200dp
so the button will occupy fixed space inside my relative layout
but i want to do it the 'right way' - using probably gravity, but there is no gravity for button - only for my relative layout that holds these 2 buttons
How to properly make 2 buttons occupy equal space inside rel layout?

Answer 1

you can use #Onik's suggestion. If you want to use RelativeLayout only then
Place dummy view in center of RelativeLayout
Put button1 toLeft of dummy view
Put button2 toRight of dummy view
Sample Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/dummy" />
<View
android:id="#+id/dummy"
android:layout_width="1dp"
android:layout_height="1dp"
android:layout_centerHorizontal="true" />
<ImageButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/dummy" />
</RelativeLayout>
