How to change application: elevation programmatically

My application works for API 19. Therefore, I cannot use android: elevation. So I app: height in my layout.

Android XML: android: elevation versus application: height

For instance:

<android.support.design.widget.AppBarLayout
    android:id="@+id/appBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay"
    app:elevation="5dp">
