material design - android lollipop toolbar: how to hide/show the toolbar while scrolling?


I'm using the new toolbar widget introduced in the appcompat / support-v7. I would like to hide/show the toolbar depending on if the user is scrolling up/down the page, just like in the new Google's playstore app or NewsStand app. Is there something built into the toolbar widget for this or should I be using it in conjunction with FrameLayout and ObservableScrollView?

As far as I know there is nothing build in that does this for you. However you could have a look at the Google IO sourcecode, especially the BaseActivity. Search for "auto hide" or look at onMainContentScrolled

In order to hide the Toolbar your can just do something like this:

toolbar.animate().translationY(-toolbar.getBottom()).setInterpolator(new AccelerateInterpolator()).start();

If you want to show it again you call:

toolbar.animate().translationY(0).setInterpolator(new DecelerateInterpolator()).start();

For hiding the toolbar you can just do :


So you just have to had a scroll listener and hide the toolbar when the user scroll !






The answer is straightforward. Just implement OnScrollListenerand hide/show your toolbar in the listener. For example, if you have listview/recyclerview/gridview, then follow the example.

In your MainActivity Oncreate method, initialize the toolbar.

    protected void onCreate(Bundle savedInstanceState) {

        toolbar = (Toolbar) findViewById(;
        if (toolbar != null) {

And then implement the OnScrollListener

public RecyclerView.OnScrollListener onScrollListener = new RecyclerView.OnScrollListener() {
        boolean hideToolBar = false;
        public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);
            if (hideToolBar) {
            } else {

        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);
            if (dy > 20) {
                hideToolBar = true;

            } else if (dy < -5) {
                hideToolBar = false;

I got the idea from:


Android Design Support Library can be used to show/hide toolbar.

See this.

And there are detail samples here.


There are actually quite a number of ways to hide/show the toolbar while you are scrolling the content. One of the ways is to do it via the Android Design Support Library or more specifically the Coordinator layout aka. super-powered frame layout.

Basically all you need to do is to have the following structure in your layout file and you should be able to achieve the result that you want.


I have actually made a video to explain how it can be done in a step by step manner. Feel free to check it out and let me know if it helps. Thanks! :)


I've been trying to implement the same behavior, here is the brunt of code showing and hiding the toolbar (put in whatever class containing your RecyclerView):

int toolbarMarginOffset = 0

private int dp(int inPixels){
    return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, inPixels, getApplicationContext().getResources().getDisplayMetrics());

public RecyclerView.OnScrollListener onScrollListenerToolbarHide = new RecyclerView.OnScrollListener() {
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        super.onScrolled(recyclerView, dx, dy);
        toolbarMarginOffset += dy;
            toolbarMarginOffset = dp(48);
            toolbarMarginOffset = 0;
        ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams)toolbar.getLayoutParams();
        params.topMargin = -1*toolbarMarginOffset; 

I've included the dp function to convert from pixels to dp but obviously set it to whatever your toolbar height is. (replace dp(48) with your toolbar height)

Where-ever you setup your RecyclerView include this:


However, there are a couple additional issues if you are also using a SwipeRefreshLayout.

I've had to set the marginTop of the first element in the adapter for the RecyclerView to the Toolbar's height plus original offset. (A bit of a hack I know). The reason for this is I found that if I changed my above code to include changing the marginTop of the recyclerView while scrolling it was a jittery experience. So that's how I overcame it. So basically setup your layout so that your toolbar is floating on top of the RecyclerView (clipping it) Something like this (in onBindViewHolder of your custom RecyclerView adapter) :

     ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams)holder.card.getLayoutParams();
     // params.height = ViewGroup.LayoutParams.WRAP_CONTENT;
     params.topMargin = dp(10+48);

And lastly, since there is a large offset the RecyclerViews refresh circle will be clipped, so you'll need to offset it (back in onCreate of your class holding your RecyclerView):


I hope this helps someone. Its my first detailed answer so I hope I was detailed enough.


To hide the menu for a particular fragment:

 setHasOptionsMenu(true); //Inside of onCreate in FRAGMENT:  

   public void onPrepareOptionsMenu(Menu menu) {

Just add this property inside your toolbar and its done


Isn't is awesome


I implemented a utility class to do the whole hide/show Toolbar animation when scrolling. You can see the article here Source code is here


A library and demo with the complete source code for scrolling toolbars or any type of header can be downloaded here:

Headers can be Toolbars, LinearLayouts, RelativeLayouts, or whatever type of view you use to create a header.

The scrollable area can be any type of scroll content including ListView, ScrollView, WebView, RecyclerView, RelativeLayout, LinearLayout or whatever you want.

There's even support for nested headers.

It is indeed a complex undertaking to synchronize headers (toolbars) and scrollable content the way it's done in Google Newsstand.

This library doesn't require implementing any kind of onScrollListener.

The solutions listed above by others are only half baked solutions that don't take into consideration that the top edge of the scrollable content area beneath the toolbar has to initially be aligned to the bottom edge of the toolbar and then during scrolling the content area needs to be repositioned and possibly resized. The JBHeaderScroll handles all these issues.


There is an Android library called Android Design Support Library that's a handy library where you can find of all of those Material fancy design things that the Material documentation presents without telling you how to do them.

It's well presented in this Android Blog post. The "Collapsing Toolbar" in particular is what you're looking for.
