how to set a selector for a child in LinearLayout

I want to create this effect

Initially

and when pressed to be shown like this.

I Know that the first thing that comes to mind is a selector. But each child is a LinearLayout out with a background set to white with an ImageView and with a TextView. So I guess I shoud set a selector for the whole child. A thing that I don't know if and how it can be done. So if you have any ideas please give me some help. This is the xml of the layout:

<LinearLayout
                    android:id="@+id/line_1"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_above="@+id/line_2"
                    android:layout_marginBottom="1dp"
                    android:layout_marginLeft="10dp"
                    android:layout_marginRight="10dp"
                    android:baselineAligned="false"
                    android:gravity="center_vertical" >

                    <LinearLayout
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_marginRight="1dp"
                        android:layout_weight="1"
                        android:background="#FFFFFF"
                        android:gravity="center_horizontal"
                        android:clickable="true"
                        android:orientation="vertical" >

                            <ImageView
                                android:layout_width="wrap_content"
                                android:layout_height="50dp"
                                android:clickable="true"
                                android:src="@drawable/sights_selector" />

                            <TextView
