</RelativeLayout>

Answer 1

first of all your parent RelativeLayout shoud have bigger height or wrap_content, and layout_weight does nothing (is for LinearLayout), so remove it

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#fff">

for both Buttons remove below lines, beause of wrap_content height of RelativeLayout parent and becausealignParentEnd will align both Buttons to one side (usually right, on RTL devices to left)

android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"

next, for left Button add

android:layout_alignParentLeft="true"

and for right Button add

android:layout_alignParentRight="true"

at the end center your ImageView with this line

android:layout_centerInParent="true"

or this

android:layout_centerHorizontal="true"

and remove these lines

android:layout_alignParentStart="true"
android:layout_alignParentTop="true"

your text View should be placed outside and below RelativeLayout
