<com.github.florent37.parallax.ScrollView
android:layout_width="match_parent"

>
<!-- ...your usual views... -->
<ImageView
android:layout_width="match_parent"
android:layout_height="200dp"
android:scaleType="centerCrop"
android:src="@drawable/background"

<TextView
style="@style/MyTitle"
android:layout_width="match_parent"
android:layout_height="160dp"
android:gravity="center"
android:text="My awesome title"
android:tag="parallax=0.5" />
<!-- ...your usual views... -->
</com.github.florent37.parallax.ScrollView>And no additionnal lines into the activity !
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

- parallaxVertical < 0 : the view will move slower than the scroll
- parallaxVertical > 0 : the view will move faster than the scroll
<com.github.florent37.parallax.ParallaxView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:parallaxVertical="1.1"

<!-- Your View -->
</com.github.florent37.parallax.ScrollView>Horizontal translation
- parallaxHorizontal < 0 : the view will move to the right
