I'd like to make a listview that, initially shows some elements of an array, loading more entries when you scroll down as maket does in example.
Can someone help me with or link solving that?
thanks
See https://github.com/johannilsson/android-pulltorefresh for one possible solution, and https://github.com/commonsguy/cwac-endless for another.

My idea is to create a kind of growing form. Now the question is: What is the best way to do this? I haven't found a library, yet. On the picture below, you can see how I thought it to be. It should go to the next step after each input and an EditText field should appear. Any advice on existing libraries or tips on which UI component should be used to realized would be appreciated. Thanks for the help!
you have plenty approach but the one i prefer to use:
make your list, then for each index assign its next EditText. by default make your all EditTexts (except first one) disabled. then add a listener each index to observe its text. as soon as it was filled tell that listener to enable its next EditText.
maybe its not so efficient but its simple and makes code more readable. and also you can extend that easily if you just implement two first indexes because the rest is just the same.
I'm trying to get the same item as Window's combobox in Android java. I realize there's a spinner but what I need is to display a scrollable list of items that the user can simply select one or more. The spinner is nice, but it's a totally different beast.
Is there an equivalent? Because otherwise I guess I would have to create a section of text items, that I would have to build my own scroll function as well as selection. Hoping to avoid all that.
Thanks.
You're going to have to write your own, or find a library. There is no builtin equivalent. Luckily it should be easy, you basically just want a recycler view where the adapter keeps track of what items you've clicked on. That will take care of the scrolling, and the display simplifies to a normal list adapter.
Import third-party library just for little feature is unnecessary, you could try change spinnerMode to dialog, then the spinner is scrollable.
Edited：
sorry, I noticed that you need select multiple items, my answer is not suitable. You could create a custom widget.
The easiest solution is using library. There a alot library you can use for that problem. Here is the some library you can used:

Or you can follow this tutorial

How do I create a button to scroll up
I see it in a lot of applications
I hope to get some help and also put some examples
Thank you
Depends on what you are using. You will need to give some extra info.
For a RecyclerView, to scroll to the top, you will do it like this:
recyclerView.getLayoutManager().scrollToPosition(0);
If you are using a ListView:
listView.setSelectionAfterHeaderView();
So here's the thing, I want to build a GridView containing few items that are movable/rearrangeable by the user. Pretty much similiar as the one you'd see on the home screen of Android.
I've looked into some places but ended up with zero result. The closest thing I was able to find was the sample of a home screen app found on developers.android.com but It doesn't have the thing I'm looking for (the items are unarrangeable).
Please give me a hint how this could be done. Code examples are also welcome.
Thanks in advance! :)
I think you should implement a drag&drop.
The GridView can handle the OnDragListener, so you could do : myGridView.setOnDragListener and do whatever you want with it.

I have a listview which has a bunch of selections. I want to keep the focus on the listview in touchmode and get the item selected. What is the best way to do that?
I found this blog:
http://bestsiteinthemultiverse.com/2009/12/android-selected-state-listview-example/
and
http://developer.android.com/resources/articles/touch-mode.html
What does the community suggest?
You can't keep focus in touch mode. You can use the "choice mode" instead to keep items checked.
To get an idea of how to use ListView I'd take a look at this Google I/O video. It helped me a lot in getting going and goes over the choice mode (I think).
