You are reading a sample chapter from the Android Studio 3. Purchase the fully updated Android Studio 3. Android Studio 3. In this chapter we will be exploring the ways in which the app bar within an activity layout can be customized and made to react to the scrolling events taking place within other views on the screen. By making use of the CoordinatorLayout in conjunction with the AppBarLayout and CollapsingToolbarLayout containers, the app bar can be configured to display an image and to animate in and out of view. An upward scrolling motion on a list, for example, can be configured so that the app bar recedes from view and then reappears when a downward scrolling motion is performed. Beginning with an overview of the elements that can comprise an app bar, this chapter will then work through a variety of examples of app bar configuration. As will be demonstrated in the remainder of this chapter, if the main content area of the activity user interface layout contains scrollable content, the elements of the app bar can be configured to expand and contract as the content on the screen is scrolled. Begin by launching Android Studio and loading this project. The first step is to make some configuration changes so that the toolbar contracts during an upward scrolling motion, and then expands on a downward scroll. At the top level of the hierarchy is the CoordinatorLayout which, as the name suggests, coordinates the interactions between the various child view elements it contains. One such element within the layout hierarchy shown in Figure is the ConstraintLayout. To achieve this coordinated behavior, it is necessary to set properties on both the element on which scrolling takes place and the elements with which the scrolling is to be coordinated. Note that the only child of AppBarLayout in the view hierarchy is the Toolbar. The value assigned to this property will depend on the nature of the interaction required and must consist of one or more of the following:. If this is not set the view will remain pinned at the top of the screen during scrolling events. Any downward scrolling motion in this mode will cause the view to re-appear. If the minHeight property is set, the view will appear during the initial scrolling motion but only until the minimum height is reached. It will then remain at that height and will not expand fully until the top of the list is reached. Note this option only works when used in conjunction with both the enterAlways and scroll options. For example:. For the purposes of this example, the scroll and enterAlways options will be set on the Toolbar as follows:. With the appropriate properties set, run the app once again and make an upward scrolling motion in the RecyclerView list. This should cause the toolbar to collapse out of view Figure The CollapsingToolbarLayout class is intended to be added as a child of the AppBarLayout and provides features such as automatically adjusting the font size of the toolbar title as the toolbar collapses and expands. The new view hierarchy that makes use of the CollapsingToolbarLayout is represented by the diagram in Figure In addition to adding the new elements to the layout above, the background color property setting has been removed. This change has the advantage of providing a transparent toolbar allowing more of the image to be visible in the app bar. Scrolling the list upwards will cause the app bar to gradually collapse. During the contraction, the image will fade to the color defined by the scrim property while the title text font size reduces at a corresponding rate until only the toolbar is visible:. Had the collapse mode been set to parallax the toolbar would have retracted along with the image view. Continuing the upward scrolling motion will cause the toolbar to also collapse leaving only the status bar visible:. Since the scroll flags property for the CollapsingToolbarLayout element includes the enterAlways option, a downward scrolling motion will cause the app bar to expand once again. Run the app one last time and note that the new title appears in the app bar and that scrolling now causes the toolbar to transition to green as it retracts from view. The app bar that appears at the top of most Android apps can consist of a number of different elements including a toolbar, tab layout and even an image view.
Disable collapsing toolbar androidAndroid CoordinatorLayout is a layout which provides control over design library components. These components behave differently when added to CoordinatorLayout. All of your main content goes here. This behavior is handled by CoordinatorLayout. Following is the layout for CoordinatorLayout with Toolbar and Tabs.

Collapsing toolbar android kotlinCollapsingToolbarLayout is a wrapper for Toolbar which implements a collapsing app bar. It is designed to be used as a direct child of a AppBarLayout. CollapsingToolbarLayout contains the following features: Collapsing title A title which is larger when the layout is fully visible but collapses and becomes smaller as the layout is scrolled off screen. You can set the title to display via setTitle CharSequence. The title appearance can be tweaked via the collapsedTextAppearance and expandedTextAppearance attributes. Content scrim A full-bleed scrim which is show or hidden when the scroll position has hit a certain threshold. You can change this via setContentScrim Drawable. Status bar scrim A scrim which is shown or hidden behind the status bar when the scroll position has hit a certain threshold. You can change this via setStatusBarScrim Drawable. Parallax scrolling children Child views can opt to be scrolled within this layout in a parallax fashion. Pinned position children Child views can opt to be pinned in space globally. This is useful when implementing a collapsing as it allows the Toolbar to be fixed in place even though this layout is moving. Do not manually add views to the Toolbar at run time. We will add a 'dummy view' to the Toolbar which allows us to work out the available space for the title. This can interfere with any views which you add. Returns the amount of visible height in pixels used to define when to trigger a scrim visibility change. Sets the horizontal alignment of the collapsed title and the vertical gravity that will be used when there is extra space in the collapsed bounds beyond what is required for the title itself. Sets the text color and size for the collapsed title from the specified TextAppearance resource. Sets the horizontal alignment of the expanded title and the vertical gravity that will be used when there is extra space in the expanded bounds beyond what is required for the title itself. Set the amount of visible height in pixels used to define when to trigger a scrim visibility change. Returns the title currently being displayed by this view. If the title is not enabled, then this will return null. Set the drawable to use for the content scrim from resources. Providing null will disable the scrim functionality. If the visible height of this view is less than the given value, the scrims will be made visible, otherwise they are hidden. Any change in the vertical scroll may overwrite this value. Any visibility change will be animated if this view has already been laid out. Set the drawable to use for the status bar scrim from resources. This scrim is only shown when we have been given a top system inset. Set the color to use for the status bar scrim. Sets whether this view should display its own title. The title displayed by this view will shrink and grow based on the scroll offset. Content and code samples on this page are subject to the licenses described in the Content License.

Recently Mindgrub was tasked with implementing a user profile view in an Android app. Initially, I was worried that we would have to go out and find a third party library that implemented this collapsing toolbar or write it myself. Luckily, Google just released the Android Design Support Libraryand this kind of animation could be created with new widgets introduced in this library. Simple, right? This should be the top level element in your fragment or activity. The behavior is specified by attributes set in its child views that are specific to the coordinator layout. This is another new element from the Design Library that declares a layout for the toolbar. The children of this element will define the behavior of the elements within the Toolbar. Setting this attribute on the sibling element binds that element to the AppBarLayout, which lets it know when it should scroll. The children of this element will declare how the toolbar is collapsing. As mentioned above, setting this attribute binds it to its sibling element, the AppBarLayout. This is simply the scrollable content. So after understanding all that, you should be all set to implement your own collapsing-toolbar view! Check out the code from my example on Github.
