I have a basic container layout in which inside it I have a FrameLayout with an id #android:id/content. This FrameLayout meant for other layouts to fill it.
Now my question is this:
Lets say I have a layout file content.xml which I want it's content to fill the said FrameLayout.Is there a way to do all this in XML?
I want something like the <include> tag, but the exact opposite. Call it <included-in>.
Is there such a thing or way to achieve it, or do I have to inflate them both, and insert the content in code?
Thanks!

as the title says, I am trying to figure out how to dynamically load imagebuttons using Android Studio. I have already pre-loaded the drawable folder with all of the images I want to make into imagebuttons.
I am using a relativelayout for this app and the main screen will scroll down. I am trying to do this without using the XML file since it seems like it makes it harder to do things dynamically.
How can I create x number of imagebuttons with these conditions? If using the xml folder would make it easier, can someone help me understand it better?
Create a custom ScrollView which find that user reach to bottom. Then inflate your view which have ImageButton. Add that inflated view in your RelativeLayout or LinearLayout which will be inside ScrollView.
Refer this:- Detect end of ScrollView
I have a cardview inside which I have several Views which I want to align one below another. For a relative layout I will use the following
layoutParams.addRule(RelativeLayout.BELOW, idofanotherview);
However I cannot find addRule() method for cardview, how do I achieve this?
As the documentation of the CardView states, this component inherits from FrameLayout. That is normal that the addRule() method is unrecognized.
If you really need to use a RelativeLayout to position your subviews then I suggest that you wrap your subviews with one.
This post gives you a good exemple of how to achieve what you need
Good luck!
So I have a Scroll View which contains a relative layout. I want that relative layout to have 3 or more layouts that can be scrolled. I know how to implement that with HorizontalScrollView, but before execution, I have no idea how many elements the HorizontalScrollView is going to have. Should I use ViewPager for this? What I would like the most is a HorizontalListView.
Would you recommend something like this:

Or should I add views programmatically in a HorizontalScrollView?
ScrollView is widget that should be used to keep static layouts inside. In general - ones that just are ~slightly bigger that the screen.
If you need something really dynamic you should use elements based on adapters like ListView, or ViewPager.
I have a ListView that I want to dynamically add items to. For the items, I want to use a specific layout that I have defined in XML. How do I go about adding the items to it and have each item use the specific XML layout?
Do I have to create an adapter and jump through all those hoops? There is only a handful of items that I need to display. Each item has a few text views that need to be populated as well as an image that needs to be displayed.
If I go with the Adapter route, I need to basically creating a custom object/class that contains the text for each textview as well as the URL of the image I'm downloading. Seems like way overkill for just displaying a handful of listview items.
Isn't there someway I can just iterate through my items, inflate a view for each and add them to the listview?
you want to use a ScrollView for your purpose. works just like a listview, except the rule is a ScrollView should only have one child layout (that layout would be containing all the items you want to put inside). inflate a layout, then addView(). rinse repeat.
Unfortunately you do have to create an adapter. SimpleAdapter is about as easy as it gets. Here's a nice example that'll have you up and running in a few mins:

Either you can create an adapter which is really not all that complicated, or you can use a ScrollView with a LinearLayout inside and inflate yourself. Either option is reasonable, depending on your requirements, but inflating yourself and adding the views to the ListView manually isn't one of them. By the description you give, it sounds like you might just want to go the LinearLayout route.
Put a ScrollView with a LinearLayout inside in your main layout XML.
For each child:
Inflate the view for the child item and populate the fields accordingly.
Add the child view to the LinearLayout using addView.
I am trying to create a layout that can fits my situation where I will need to have a layout that keeps the views like imageview or textview or probably a combination of a few. while on the top right of it, i will need to have two buttons on top.
However, this layout has to be dynamic where I can select whether if I want to show the buttons or not. How should I go about it?
You can use any layout you want really, although it sounds like a horizontal LinearLayout would fit your situation the best.
You can then control visibility of individual elements via setVisibility(View.GONE) and setVisibility(View.VISIBLE), or simply through addView.
