                android:id="@+id/textView2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:layout_alignParentTop="true"
                android:text="Top"
                android:textColor="#ffffff"
                android:textSize="18sp" />

		parallax.setImageViewToParallax(imageView);
		parallax.setViewsBounds(1.3);

	}

ListView

  <net.appkraft.parallax.ParallaxListView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:overScrollMode="never"
    app:zoomRatio="1.4" >

</net.appkraft.parallax.ParallaxListView>
