android - Align and wrap imagebuttons in linearlayout -

i have linearlayout has imagebuttons aligned horizontally, @ bottom of parent layout. exactly, want like:

this how doing it:

<linearlayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_gravity="end|bottom"         android:background="@color/dim_foreground_disabled_material_dark"         android:orientation="horizontal">          <imagebutton             android:id="@+id/new_1"             android:background="@drawable/_dashboard_1"             android:layout_width="wrap_content"             android:layout_height="wrap_content"/>          <imagebutton             android:id="@+id/new_2"             android:background="@drawable/_dashboard_2"             android:layout_width="wrap_content"             android:layout_height="wrap_content"/>          <imagebutton             android:id="@+id/new_3"             android:background="@drawable/_dashboard_3"             android:layout_width="wrap_content"             android:layout_height="wrap_content"/>      </linearlayout> 

i have tried give weightsum linearlayout, , assign weights imagebuttons. stretches aspect ratio of drawables.

how should use layout arrange them in bottom of view, evenly spaced, centrally placed , without stretched out aspect ratios of drawables..

if want achieve 1 using linearlayout try one..

   <linearlayout     android:orientation="horizontal"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:weightsum="10">       <imagebutton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/imagebutton10"         android:src="@mipmap/ic_launcher"         android:layout_marginleft="20dip"         android:background="@android:color/transparent"/>    <view android:layout_width="0dip"          android:layout_weight="5"          android:layout_height="1dip"/>     <imagebutton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/imagebutton9"         android:src="@mipmap/ic_launcher"         android:background="@android:color/transparent"/>     <view android:layout_width="0dip"         android:layout_weight="5"         android:layout_height="1dip"/>     <imagebutton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/imagebutton8"         android:src="@mipmap/ic_launcher"         android:layout_marginright="20dip"         android:background="@android:color/transparent"/> </linearlayout> 

or if ok relativelayout try one...

    <relativelayout     android:layout_width="match_parent"     android:layout_height="wrap_content">       <imagebutton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparentleft="true"         android:layout_centervertical="true"         android:id="@+id/imagebutton12"         android:src="@mipmap/ic_launcher"         android:background="@android:color/transparent"/>      <imagebutton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/imagebutton11"         android:layout_centerinparent="true"         android:src="@mipmap/ic_launcher"         android:background="@android:color/transparent"/>      <imagebutton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/imagebutton13"         android:layout_alignparentright="true"         android:layout_centervertical="true"         android:src="@mipmap/ic_launcher"         android:background="@android:color/transparent"/> </relativelayout>
