the xml including in not resize height of buttons, hides lower keys wich there no space

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"           xmlns:tools="http://schemas.android.com/tools"           android:layout_width="match_parent"           android:layout_height="match_parent"           android:background="@color/background_color"           android:orientation="vertical"           android:weightsum="3"           tools:context="fragments.registerfragments.drawerregisterfragment">  <imageview android:layout_width="match_parent"            android:layout_height="0dp"            android:layout_weight="1"            android:src="@drawable/bomb_icon"/>  <include layout="@layout/includable_view_numeric_keys"          android:layout_weight="2"          android:layout_height="wrap_content"          android:layout_width="wrap_content"/> 

oke, found problem, should have made linear layouts hold buttons jave hight of 0dp, , let layoutweight take care of it. here new xml:
