I am working on a restaurant automation application in android studios. In my MenuActivity where orders are placed, I would like to create buttons each time an order is placed in a different activity called ChefActivity. The idea is that when the Place Order button is clicked in the MenuActivity, a button will appear in the ChefActivity so the chef can click that button to view the order. Is there a way to dynamically create a button in one activity to then display in another activity? I have done much research on this and have no been able to find much helpful information. Any and all help is greatly appreciated. Thanks in advance!
You should to use Preferences or SQLlite to store information, and when you switch activities just read from them, it's looks like, you click on button in 1st activity, write it to database, and then when you start 2nd activity, just read from database and place data to button.

I'm trying to create an overlay that is triggered when a button is pressed. This overlay is supposed to allow the user to add their contact and I was wondering how can I use fragments to get this effect like you can see in this mockup.
I am in a dilemna over using fragments is the right choice. My reasoning being that I only need to have it do one task that is adding contacts, and thus I do not need a whole activity.
This is what I have on the main activity right now
I would really appreciate any help on understanding how to make this work.
You can use a DialogFragment.
It behaves like a normal Fragment for the most part. Here is a guide for a basic implementation https://guides.codepath.com/android/using-dialogfragment
They appear automatically in the center of the screen. To get it a bit lower like in your mockup you can change where it is in the window. Here is an answer showing such Position of DialogFragment in Android
For example, I have activityMain which contains the main logic of the Application, but it should be opened from several buttons that stored in other activities, and some activities contains multiple buttons too. And they should call activityMain. So i need to pass different data from db depending on which button called activityMain

You should try doing it by urself in one of the many ways its possible to. Then we could provide some help with your idea or show you better solution. I think you are looking for RecyclerView (https://developer.android.com/guide/topics/ui/layout/recyclerview). It lets you show some similar views but with different data inside. Also as an item inside RecyclerView you can try CardView.
Using only RecyclerView you can also use:

You can also search for a library that has everything you want inside already implemented. For example the first library that came out after i typed it in google : https://github.com/Ramotion/cardslider-android.
I am a newbie in Android and currently I am designing an application where I have faced a big problem with changing views. I have 3 classes, each one for a different screen. I use a button to change pages but it does not seem to work. Every time I move to the next screen, the variables methods etc of the 2nd screen are located in a different class. Can you please show me the simplest way to do this? Thank you.
Place each screen in different Activity. Start respective activities according to button presses. To pass data between activities use Intent.
Activity Reference
Intent Reference

I'm a noob Android developer. I learned of the basic UI controls and different types of views that I can utilize.
Now my problem is, I need to show list of items using the ListView that is being shown full screen. when I click on an item it should load a TextView full screen. when I click the back button it should go back to ListView again..
Can someone point me where I can learn such stuff?? any support or even external link is greatly appreciated.
Thanks in advance.
Write your text view in a different activity. And when ever you click on a list item start that activity putting your text in the intent. Fetch the text in that text view activity in onCreate() from the intent and set it to text view. Obviously when ever you click back you 'll come back to list view activity.
