        &lt;ImageView
            android:id="@+id/imageView1"
            android:layout_width="match_parent"

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentLeft="true"
            android:text="Bottom"
            android:textColor="#ffffff"
            android:textSize="18sp" /&gt;

        &lt;TextView
            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"

    &lt;TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/relativeLayout1"
        android:text="@string/hello_world" /&gt;
&lt;/RelativeLayout&gt;

Setting zoom ratio of the parallax :

  protected void onCreate(Bundle savedInstanceState) {


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

}

ListView

In your activity xml

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

        image.setImageResource(R.drawable.teste);
        AbsListView.LayoutParams params = new AbsListView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 200);
        image.setLayoutParams(params);
