Question

My image button is 40px in height, but my gallery is a lot bigger in height. Right now, my imagebuttons take up the entire space they are given, and is the same height as my gallery. Is there anway to keep the buttons their original size while keeping this horizontal layout?

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:orientation="horizontal"
        android:paddingTop="20dp" >

        <ImageButton
            android:id="@+id/left_arrow"
            android:layout_weight="3"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/shared_arrow_left_button_selector"
            android:scaleType="fitCenter" />

        <Gallery
            android:id="@+id/gallery"
            android:focusable="true"
        android:focusableInTouchMode="true"
        android:layout_weight="1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:spacing="15dp" />

        <ImageButton
            android:id="@+id/right_arrow"
            android:layout_weight="3"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/shared_arrow_right_button_selector"
            android:scaleType="fitCenter" />
    </LinearLayout>

You are applying

android:layout_width="match_parent"
android:layout_height="match_parent"

to both the ImageButtons so they are filling the height, if you just want ImageButtons to wrap their original size just change them to wrap_content and remove the layout_weight property. Also when you are applying layout_weight="1" to gallery just change android:layout_width="0dp" as the width will be managed by the layout_weight property itself. Your final layout should be like,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="horizontal"
    android:paddingTop="20dp" >

    <ImageButton
        android:id="@+id/left_arrow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleType="fitCenter" />

    <Gallery
        android:id="@+id/gallery"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:spacing="15dp" />

    <ImageButton
        android:id="@+id/right_arrow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleType="fitCenter" />

</LinearLayout>
