try this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal" >

<LinearLayout
    android:id="@+id/foo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:onClick="newItemOnclick"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/id_new_big_list_item_image"
        android:layout_width="50dip"
        android:layout_height="50dip"
        android:adjustViewBounds="true"
        android:src="@drawable/photo1" />
</LinearLayout>
