Can I pick your brain?

Hi All

I'm currently trying my hand at building a weather app (Inspired by Ben). At the moment I'm looking putting together some sort of Horizontal view to show a brief summary for each day of the week e.g. Image on top with with two TextView underneath showing High and Low temperatures.

I figure that a ListView would be my best bet thanks to the magic of adapters - but it turns out that the SDK doesn't come equipped with a Horizontal ListView :(. So I've turned to a HorizontalScrollView containing a RelativeLayout inside. However if I continue down this path (based on my limited knowledge) I cannot use an adapter to fill the ScrollView - Instead I'd have to update all the images and TextViews line by line, which doesn't seem very particle.

Has anyone else had a similar issue?

I've found the TwoWayView library on GitHub but I - 1, Can't figure out how to add it into Android Studio & b. Can't get it to work in Eclipse either :)

I'd really appreciate any help and advice you'd have to offer.

I used a ScrollView to do a handful of items horizontally before, but never a horizontal ListView with more items. This is a great question without a satisfactory answer (at least not with a quick search). This library looks promising, though: https://github.com/sephiroth74/HorizontalVariableListView

Tell me about it! :) I almost went mad trying to find the answer to my question.

I did see a reference to that library on my google travels, the problem I had though - like with the TwoWayView lib, is that I can't figure out how to get it into Android Studio. Each time I try I always end up with some sort of gradle error... I think I need to re-watch the videos you made on 'An Overview of Android Studio'. I'm pretty sure you adding/importing libraries.

If I get stuck I'll put my hand up and ask for help :)

Sounds like a plan! If you update AS to the latest you should be able to add the following line in the build.gradle file in your app module. This feature of Gradle is awesome; it automatically includes the version that you specify without any additional work. I'll try it out myself if I have a chance, too.

compile 'it.sephiroth.android.library.horizontallistview:library:+'

Your dependencies section should look something like this:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    compile 'com.android.support:appcompat-v7:19.+'
    compile 'it.sephiroth.android.library.horizontallistview:library:+'
}

As for using it, I see the library includes a demo project. Hopefully there's enough there to figure out how to include it in your own project.
