I got 100 ImageButton, I need to make a list of these button, I tried with a static list like the scrollview, It work but the app need 4 to 5 seconds to load all the ImageButtons, so I want to try to make a list that load buttons when user scroll down. In this way the app does not have to load all the buttons at once, I've been looking for a solution for days but I can not find it, someone know how to achieve this list of imagebutton?
You should use ListView or RecyclerView. I recommend starting with some lessons:List view. Ask if you will have some problems.

I'm a beginner with short knowledge of programming, I've just started learning android development. I'm making an app and at one of the pages I have to make a certain kind of design that I cannot figure out how to or can't even find them in the internet. Basically, as you can see in the images below, next to the first textview, there's a little arrow. Whenever the user clicks on that arrow, two edittexts should appear below that texview just like in the second image and kind of drag the rest of the textviews down. I'd be really grateful if you guys could help me do this or at least provide me with some information on where to search this kind of problem solution. Thanks.
Just create your desired layout in xml with 2 edittext below each textview. But make sure You take these 2 edittexts in a single container. Lets say LinearLayout.
Then you would be easily able to show/hide these lineralayout based on the TextView click.
Or If You are using recyclerView, then it would be more easy. In this case, You have to show the 2 edittexts for currently clicked item only and will need to hide for all others
I've already coded a ListView with images. But I'd like to add animations to it.
What I exactly want is I want to have two images in a row but only one visible. When I touch on it, the second should appear and the first should disappear.
I know how to make such an animation but not with a ListView.
Does anyone know that?
I think you are looking for somethink like This.
You can take custome listview with images and according to handle the animation on row click.
I have seen an app which has different type of scrolling. I hope images attached will be able to explain it. Here the list when scrolled up, moves up by taking DownloadAll, Playall button up too. Later on DownloadAll and PlayAll button stops going up and only the list scrolls up.
I don't know what this is called as. I tried searching, but could not find anything similar.
How can I achieve this type of scrolling?
Take a look at "Libraries for developers" it has a section of listview where you can find different styles of listviews (plus scrolling animations such as sticky, animated scrollview, flabby etc...)
My Problem, is that I don't even know what to search for.
I want a ListView.
This ListView has some Elements with a "sticky" state.
If I scroll down the List on the device, I want that all ListElements with state "sticky", to be sticky ontop of the list (non-scrollable) till there is another one "pushing it away". The rest of the elements are supposed to scroll as normal.
I've seen that kind of List in the Google Market. If you have a big screen you can see that list on the Detailview of any app on the left side or if you have android JB, the same effect is on the google search bar in the google now app.
Image One: You can see the normal ListView on the left side

Image Two: You can see the normal ListView scrolled up a bit

Image Three: You can see, what I actually want. The View is scrolled up but the "sticky" price does not disappear. Instead of that all other elements, went under the "sticky" one

How do I do that?
I think that you meant to do some "synchronized scrolling".
There's a great post explaining how they've done in on Google Play:

Hope that's what you were looking for..
I believe that is a separate component, not related to ListView in any way.
Just create the header, let it be a RelativeLayout, or LinearLayout, and fill the rest of the area with the ListView set to fill_parent. Then, when you'll scroll the ListView, the "header" will stay sticky (as it is a separate component), and the list will scroll down.
I have a gridview with some objects inside it and I have an alphabetic list that is compose by a lof of textviews.
I want to click on "A" and the gridview is going down until the letter "A" and the same with the other letters.
Maybe that won't be a problem but the big problem is when I scrolling the gridview, I want to know which items are display and try to get the first item to decide which letter is it.
That look like the iphone contact
