Android Exposed Dropdown causes exception

I need to add a drop down to my app, which is running on the AppCompat theme, since we are not using the Material design components, but rather have our own design for buttons, etc.
For a simple feature, I need to use a dropdown and here I think the Exposed drop down from the Material design theme would work nicely.
However, if I'm not specifically using the MaterialComponents theme in my styles, the app will crash whenever I try to use the style on the TextInputLayout.
Is there a way of using the nice Exposed dropdown from MaterialComponents without using the entire theme (as this overrides all colors for buttons and such)? Or maybe just a simple way of getting a nice and simple dropdown otherwise. Spinners seem kinda hard to work with..
Cheers.

What is use of toolbar and action bar?

I am new to android i didn't understand what is the use of toolbar. In place of toolbar we can use any layout like relativelayout then we can design it.
And in toolbar if you want add any button we are creating menu folder and we are doing so many nonsense thing
So inplace of taking toolbar better to take layout.
Please anyone give me the answer why we are using toolbar and actionbar

Toolbars are useful because you can use them in layouts, apply any themes and even create a menu. Toolbars extend viewgroup - that's makes them extra flexible. They are used in layouts to create material designed themed apps. Why does that matter? That's what the users on Android are used to and if you have a custom toolbar you might confuse your potential users. And you get all of this functionality for free, instead of using a layout and manually setting the styles and menus.
So why should you use the supplied toolbar? It's the same with using any component created for use on Android; Don't Repeat Yourself. DRY is the golden rule of software development, and by using these layouts across apps it makes it easier for the users of your apps to understand how to use your apps

It's not an absolute requirement to have a Toolbar, but it has been a staple of the material design paradigm for a while. On many apps, it's used to show the app title, or to house navigation components for example. I suggest you take some time and read the material design rationale for the Toolbar. https://material.io/develop/web/components/toolbar/
The documentation provides some context and suggested usages of the ToolBar in the first sentence of the description.
MDC (Material Design Component) Toolbar acts as a container for multiple rows containing items such as application title, navigation menu, and tabs, among other things.

advanced Android menu

Hi Everyone
I'm new in android and i'd like to do a menu for an application.
I want to replicate the menu style of this game that has different section
http://i.giphy.com/l4Jz4PbvjJEZHZn8c.gif
I have 3 different xml layout that i want to show in my horizontal style menu capable of swiping from a layout to another.
I have heard i could use something called horizontal ListView but i don't really know how to use it.
How do i do?

try Sliding tab Layout. Its the same function just need to edit the codes for different design

Android- Can we create material views programmatically?

Is it possible to create Material Design views (like button, textView, ...) programmatically?
like
AwesomeButton btnTest=new AwesomeButton (context);
i want full featured library like rey5137 but without XML usage and support old android(maybe Android 2.3 and up).

material design is all about different combinations of items in xml. you cannot design without xml. it is not java swing don't forget, whatever you want to design their base should be on drawable or layout folder, not on java code
update for the edited question
in your example, you say AwesomeButton, in order to have something like this, you need to have a library, which also has xml design file including all those fancy visual effects. If you don't design how are you supposed to create a pre-designed button.
chamran, you are making it complicated my friend, you can't design a button via code, you have to have a xml file for your own custom materials. Even the default button has a xml.

Chrome-like display of menu

I'm trying to find some information on how to create a menu that looks like the top of the menu for chrome for Android. I have tried experimenting with implementing icons for Android 4.0, but no luck. Tried googeling, but the only thing i found was an answer that said icons can't be implemented when API >= 11.
How does Chrome do it then? It's made for devices that's 4.0+!

Use popup list window to achieve this. As you can add header and footer to any list, you can create one linear layout with back forward and star like options.. Add that view to the popup window.

Any ListView can be associated with HeaderViewListAdapter, using this you can attach seperate layouts as a header and or footer to your listViews.
As Vinodkumar said, you can also use ListPopupWindow with HeaderViewListAdapters.
In the Android reference: HeaderViewListAdapter and ListPopupWindow
