I want to create an audio app to promote music. I want to have a regular Activity that has a listView and then a container or two to display standard information about the Artist. Music files will be inside the ListVIew with a button to play and stop the selected song. So to sum this up how should go about putting a list with buttons inside an Activity with other container? Hopefully this makes sense.
Thanks.
You should really check out this great Notepad tutorial. You create a basic Notepad, which uses a listview, and a database. If you just starting out I can tell you from experience, these tutorials are the best way to learn. There are tons of them out there :).
EDIT: While I could just give you the code to do what you want, you would learn nothing in the process :).

This is more of a curiosity than anything else but it would be good to get some feedback from everyone on possible problems and solutions etc.
Is it possible to use one "host" activity and use that activity to display 3-4 different activities?
I already use tab host in my app and this doesn't seem to fit my needs in regard to the menu idea, ill explain what I'm trying to do as it may help.
Im trying to find a nice clean solution to playing background music, but this could be applied to other functions as well, but essentially, after the splash screen i would like a "host" activity to load first and in that activity, load up a menu activity, when the use presses a button the menu activity, i would like the next activity to load up still inside the "host" activity.
I'm hoping this would make playing music etc as clean as possible and with as little extra coding as possible.
Is this idea possible? would it be beneficial? what would be the best way to accomplish this?
Like i said this is more of a curiousity than a "gimme code to do it", I can work that out once i know the direction to head in & if its possible, I mainly want this for b/g music at the moment but im sure this could be applied other functions.
Thanks for looking, reading giving your thoughts :)

Im not necessarily asking for code but more the concept of how to achieve the following.
Im creating a bird-song app where I have a single-button that needs to play two different mp3 files as the user selects one or the other. My hope is to have the single 'play' button and then a radio button for selecting either mp3_A or mp3_B to play.
How would I go about achieving that?
THANKS!
Please try to google keywords if you are really need something most likely someone has already have tutorials on it.
Here is something off the first type on google search: site.
Oh completely forgot just use the basics for mediaplayer class like stop and open whenever a radiobutton is clicked that should solve this request of yours.
Thanks guys. This topic describes a great fix!

I am building my first Android application that will guide the user through a series if listViews containing categories until the user reaches the final activity where a large block of text will be displayed.
My question is:
Can and should I build the listViews dynamically in one activity or should I build them all in eclipse manually?
There will be a lot of activities. I dont mind building them, i just dont want to bog down the application. From what I understand Android does a pretty good job of destroying old activities, but I am not sure the impact of having hundreds of activities would be.
Thanks in advance for your advice.
Sounds like one activity containing a ViewFlipper to hold the list(s). Presumably the list isn't the only thing you'll be wanting to display. You'll probably want to show a heading of some kind, and the user's location in the hierarchy.
What if the user hits back button? Will the app navigate to the previous activity?? Or will it be disabled?
I would suggest you make different activities since its the easiest way to do
I would like to put fairly extensive help information within my app - both "how to use" and explanation of what one is seeing.
The app (map oriented) has a row of buttons at the bottom, and I was considering adding a help button.
Context sensitive help is mostly not appropriate, btw.
What are common and best practices for this?
Thanks
I wouldn't suggest using a help button, once the user knows how to use your app it will be useless, and will only takes some space.
What I do (but it's maybe not the best practice) is to show a popup on the first use. Within the popup I put some basic help and a link to my website which fully explains how my app works (with some screenshots to make it user-friendly). I also put a "Help" button in the activity menu which redirects to my website again.
What I can suggest is to explore by yourself how other android apps shows the help information, and reuse or adapt the one you prefer (this is what I've done).
I have put help into a menu item as I expect new users to click the menu button anyway (my app, Zwitscher also has a button bar at the bottom).
Clicking the menu item then starts an Activity that simply shows a table view that explains the various buttons in the system and contains a link to more information online.
See https://github.com/pilhuhn/ZwitscherA/blob/master/src/de/bsd/zwitscher/HelpActivity.java and
https://github.com/pilhuhn/ZwitscherA/blob/master/res/layout/help.xml
Another option I've seen sometimes is including a help option in the preferences/configuration screen.
Usually it starts a new activity with a sequence of steps to make the user understand everything.
I have a ListView in Android that needs to have the ability to be manually reordered. An example would be within Android's Music Player application, when you can change the order of tracks in a playlist. I know how to programmatically change the order of a ListView, but not how to do it in regards to a touch and slide approach that can be found in the Music Player application.
Thanks in advance,

There's nothing in the framework for this at the moment, you'll need to look at the Music source code to get an idea of how to implement this. You can also, of course, copy over parts of the relevant implementation as you see fit.
