I dread designing UI for Android apps, and I have been searching and trying every possible combination of things to get this the way I want it, but I just cannot seem to get it right.
I want to have a simple Android app that has a text field and a send button next to each other on the bottom of the screen (I already have this correct), and I also want a functional chat area filling the rest of the screen above.
It obviously needs to be scrollable, and I would like to be able to add a new line to the bottom of the chat by doing something like chatBox.add(username, text).
This is the type of view I am looking for:
<bob> my name is bob
<bill> hi bob, my name is bill!
<bob> we are having an awesome conversation, bill
<bill> both of our names start with a b
<bob> how right you are
I had made such app. For chat window I used listView. ListView has stackFromBottom mode. So the last added messages will be on the bottom of ListView. Also I created custom Adapter extending ArrayAdapter, so it is easy to add new messages.
Here is a nice example, how to use listView with adapter and add new items.
Leonisdos is right, you shoud use listView. Do you know the app Irssi-ConnectBot ? I think you should have a look in its source code to have many good examples.
Here the code.google project of Irssi-connectbot (and the github)
Wrap a TextView in a ScrollView. Use append() on the TextView and fullScroll(View.FOCUS_DOWN) on the ScrollView when you append new chat entries.
For longer chats, Leonidos' ListView approach is more efficient, but I thought I'd mention this one.

I'm quite new to android studio so be easy please.
For now I'm doing my best to implement MVVM pattern using Kotlin.
I want an app which is shows Persons in a list (For now I'm using Recycle View with a Text View inside). I want user to be able to tap on a Person and after tap Person card would pop up. The questions are:
Which component should I use instead of Text View to observe user's tap?
Which components should I use for Person card? Person(Name, Last name, Age, Avatar(jpg img))
You can just use the text view. Just set an onClickListener to know when someone taps it.
Depends on the exact UI you want. A dialog might fit, with whatever you want inside it.
Hi I am developing an android app and I want to add a similar component that I found in another app this is the structure:
So I want to make something like this but I can't figure out what components of xml android to use I was thinking of a CardView with a ListView inside or use a table layout instead but I dont know if that's the right choice because it has to be dynamic, when I tap the + button I have to add a new row or when I tap the - the last row has to disappear also the weight and reps elements are text field's for the user to input data. What's the best way to achieve this?
I have used this forum when I didn't know how to do something, but now I have decided to begin participating in it.
I would like to know how could I do a dropdown text (maybe it has a specific name and that's why I don't find any results on the internet). I mean, I have some tags in the screen (About, Company, Contact, ...). Each of these tags has a down arrow on the right side, and when I click it, it has to display (and hide if it's clicked again).
Here are the links with the images of what I want to do.

Thank you in advance!
You should use an ExpandableListView component.
There is a tutorial for it here.
Finally I did it with ImageViews and TextViews using the property android:visibility. Now that it's a static version is working properly. I hope that it continues working well when taking the information from the DB
Im creating an in app chat and I cant figure out how to keep the listview I have implemented to keep from growing down below the edittext box I set up to take user chat. Whats happening now is that new lines add to the listview just fine but after the list grows large enough it starts to add to itself below the edittext box. I find that pretty annoying and imagine a user would too so my question is:
How can I keep a listview from growing downwards.
Id like for new fields/text to add to the bottom of the listview but be placed ontop of the edittext just like any normal chat would do.
It's very easy, simply set the transcriptMode. If you do it from XML, you have the choice between normal and alwaysScroll:

This is how the built-in Google Talk and SMS/MMS applications are implemented (they use the normal transcript mode.)
friends,
i want to perform functionality same like stackoverflow tags as we do normally creating a question separated by commas in android.
i know we have auto complete text view in android any one suggest me can i use it for multi selection?
or any useful way to achieve this?
any help would be appreciated.
it can be achieve through two ways
i devised my own machanism so may b you people have better approach than me please share too.
1) simple
2) advance
1) in simple we can use autocomplete text view and only use single tag with hard coded values which is limitation.
2) i have used a popup page with a Edittext and add button on top and listview with checkboxes below it.
fixed items i have already loaded into list view with checkboxes so that i could select multiple tags.
and in case of if i want to add my custom tag then i use that edit text above list view and store it in temporary data and
then finally using bundle i show selected values where i want seperated by commas.
thats it.
