What is it called and what kind of library should I use so I can make one like it?
That can be created by using collapsingtoolbar layout along with FAB a.k.a Floating action button . ImageView is placed inside collapsingtoolbar.
For more information see this answer :

Did someone already achieved to transform an extended FAB into standard FAB and vice-versa ? I know how to add a FAB into my layout and how to detect the list scroll threshold but i really don't know how to achieve this transformation (Please see the reference to see what i would like to do : Extented FAB into standard FAB).
Thank you a lot
Kind regards
Just add 2 magical lines for this behavior this code only works for ExtendedFloatingActionButton
floatingButton.shrink(); ///This line of code hide text and show Icon of floating buttion
floatingButton.extend()///This line of code show text and icon of floating button
I want to create animation for my fab like this example in material design principle, I realized that icon inside fab has 2 animation. One that rotate share icon and another is alpha animation simultaneity. after that another icon replaced. but when I create animation set for this goal, whole fab rotated and disappeared, but I want that icon inside fab take this animation. How can I create this animation? thanks
The best way to achive that is create a Custom Floating action button class and Override your setImageDrawable method, doing the translation animation there. Also you can modify your onDraw method to add an animation to your FloatingActionButton
You have to use a third-party library to achieve this result. Take a look here It is important to notice that it is possible to implement your own way but you would be kind of "reinventing the wheel".
If you want to do this anyway, you can create several FABs and change visibilities and move them with simple animations.
Could someone please provide an example of how to create a bar with buttons at the bottom within CoordinatorLayout? My app consists of AppBar (top) that contains buttons invoking application-wide action. However, I'd like to have a view specific buttons placed at the bottom.
I'm not sure if this UI design is still supported/recommended when using the new Disign Library and AppCompat.
Any suggestions will be greatly appreciated.
Thanks.
How can we create a collapsing toolbar layout like Yahoo News Digest application ?
Have you tried adding app:behavior_overlapTop="50dp" to your scrolling view? (This is the default behavior. Code can be found here.)
Apparently, it should support that attribute to make the scrolling view overlap your app bar.
Start by implementing the square collapsing toolbar as you can find in many other guides and then set that parameter.
If that does not work, you could write your own Behavior I guess, inspiring from the one I linked you (which is the default AppBarLayout behavior that allow the coordinator layout to collapse the top part.
To make the image not square you need to use a semi-transparent image or edit it by code.
I need an information about Toolbar. I would like to add four images in my Toolbar like home, news, search and message. So i've putting Imageviews in the Toolbar. Now I don't know how to add listener at these images...how could I do that?
I have also a navigation drawer and I want that, if you press the Imageview in the Toolbar, you go in a new Fragment and not in a new Activity.
So how could I do these two things?
Thank you for the answers.
i guess you know how to add your imageViews to your ToolBar if not check this .. After that get a reference to your ToolBar use findViewById
Toolbar tool = finViewById(R.id.mytoolbar);//cast it to ToolBar
ImageView im1 = tool.findViewById(R.id.myimageviewone); // cast it
//same for the others
// now you can set your click listeners
//in your onclick listeners you use fragmentmanager along with fragmenttransaction
//to start a new fragment in your layout or on your layout, you can google
// for that
You should just be using the regular MenuItem functionality built into the Toolbar (and same as ActionBar). Look up any ActionBar tutorial, and look into using ,creating MenuItems (you will do most of this in XML). You will then be able to use the OS framework, to capture onClickListenters.
Here are the docs (you will notice the MenuItem has an icon attribute, which will place the images into the Toolbar):
android:icon="#drawable/ic_new_game"
Docs:
http://developer.android.com/guide/topics/ui/menus.html
I would recomend to use ImageButtons. You can set image sources which will be displayed as a Button and they behave like normal Buttons with OnClickListeners.
