QUESTION
My app consists in letting you add lists in which you can keep your notes. Therefore, I have this NotesListActivity where I can add and keep my Lists. I wanted to filter this lists following the https://www.youtube.com/watch?v=CTvzoVtKoJ8 tutorial and then I tried to adapt it to my code like below. Could you please tell me what is the problem here, cause I don't even get an error, I just not get any title of list as result. So, this is what I have in my RecyclerAdapter:
...ANSWER
Answered 2021-Jun-13 at 20:18The problem is that you are using an empty notesListAll
list for filtering results; you need to populate it with the list of notes in the constructor

...ANSWER
Answered 2021-Jun-15 at 19:49You can use simply intent.putExtra
instead of worrying about which variant like put_____Extra
to use.
When extracting the value, you can use intent.extras
to get the Bundle and then you can use get()
on the Bundle and cast to the appropriate type. This is easier than trying to figure out which intent.get____Extra
function to use to extract it, since you will have to cast it anyway.
The below code works whether your data class is Serializeable or Parcelable. You don't need to use arrays, because ArrayLists themselves are Serializeable, but you do need to convert from MutableList to ArrayList.

I'm following a tutorial about RecyclerView, but I can't write ct:
the way he did. I typed in manually, but it does not work. I'm not sure how he typed it. He typed in this
, then android studio writes ct:
automatically. What do I need to type to do that?
MyAdapter is a class I created for RecyclerView. Here is the code for that class:
...ANSWER
Answered 2021-Jun-15 at 19:45The little lighter colored "ct" prompt is just a visual aid and it does not always show up. When you provide a raw value as an argument, it will show the prompt (like this, 1, or "foo"). When you provide a variable for the argument like ctx, foo, etc, it does not show up. This goes for all functions that take arguments.
The moral of the story is, it is not important and can be ignored.

QUESTION
I'm doing a Group Chat with Firebase and currently I'm using a RecyclerView to display chat messages and I'm having a problem. When you open the app in the fragmented home and you go to chat activity and start chatting (adding elements to recycler view) all goes fine. But, when you go via the NavigationDrawer to another fragment and get back to the chat fragment using again this Navigation Drawer. When you add one element in the chat it appears all in the blank it just displays the last message. Anybody knows why does this happens?
Here I leave the RecyclerView Adapter Code:
...ANSWER
Answered 2021-Jun-15 at 13:55To solve your problem you can just remove the OnResume method because you are initializing the array every time you change between fragments and that is the problem.

QUESTION
I'm new to android studio and i'm not sure what was going on with it. How can I solve this error?
In the logcat, it mentioned that I required a view for recycler_food_list which apparently I had already coded into the foodlistfragment.java.
Logcat
...ANSWER
Answered 2021-Jun-15 at 03:29You're doing inflater.inflate(R.layout.fragment_menu, container, false);
, not inflating your R.layout.fragment_food_list
. You'll need to inflate the right layout to find your Recycler view.
QUESTION
ANSWER
Answered 2021-Jun-13 at 03:02So, this is not exactly what you want but at least it has the same layout as you want with a simpler approach.
So, the main challenges are:
Taking a curve cutout on the
CardView
probably need to be built programmatically with canvas for a better result. But for simplicity, this is replaced by aBottomAppBar
wrapped in aCoordinatorLayout
in order to have the curve effect with the top circle/gap.Replacing the top
View
withFab
in order to have an Inset FAB by setting thelayout_anchor
to theBottomAppBar
. Check material design for this.And having the cutout behavior requires to make the FAB like it doesn't exist by setting a transparent
backgroundTint
& removing theoutlineProvider
Making the top cutout (gap) of a particular row get overlapped to the top row like if it is a part of it. This works with the negative margin on the root view.
