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 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 have a GridView in which I am showing list of books. I have tried by creating custom layout and putting cancel button onlongclick listener of a view. But i am not able to apply a shaking animation to the items. Can anyone guide me how can i apply an animation to the items and make it similarly like iphone?
Now I want to provide feature to delete the Multiple items from the GridView like the View which shows as below:
I did lots of research for this ,but failed to get such kind of view in Android.
Can any one guide me for this?
You'll have to make a custom gridview for that. Place a button (x) on top of the grid item and set its visibility to invisible.. onLongPress of the grid item, make that button visible.. onclick of the button, delete that grid item by getting its id.
Hope I have given you a direction.
I am trying to create something like (very poorly created in paint) in the image below:
I have only 4 items, and it won't be more. the items contains two textviews. But when you click on an item, i want it to expand, (like item 2) to the bottom with three extra buttons. It would be really nice if there would be some nice expand animation. I don't want this list to be scrollabe, it just need to fits in my screen. And only one can be expanded.
I think there are two options, but maybe i am missing something.
1) Create an itemlayout.xml, containing an linearlayout or something containing the extra buttons, set to linearlayoutbuttoncontainer.setvisibility(View.GONE). And then build a switch, which closes the others than the clicked one, and set the visibility of the clicked item to visible. This would be fairly easy to build i guess, i don't foresee a lot of problems. But is it possible creating an animation or is there only a sudden screen change?
2) expandable listview, with the buttons in the expandable item. I know its possible to make only one item expanded, by rembering the expanded one and closing it again. But is it possible to make it like this, with the buttons in the expandable part? Actually i've never used an expandable view.
Anyone know what the best solution should be?
Thanks
I would recommend using an expandable list view for this, as your second option described. For this type of list you can use a expandable listview adapter, describded here:
http://developer.android.com/reference/android/widget/ExpandableListAdapter.html
This adapter has both a getGroupView(open/close items) and a getChildView method in which you can inflate your layouts, or manually set them up. If you have used ordinary listviews I'm sure this wont be a problem for you, since it's basically the same operations.
This means you should probably inflate your childViews with a LinearLayout containing three buttons. Then you have to implement functionality for your collapse/expand logics by keeping track of which item index is opened.
I did this tutorial when I first started out with exp.list views, I found it helpful:

Good luck!
You gotta check this http://udinic.wordpress.com/2011/09/03/expanding-listview-items/ it works neat. If you got any more problems, do ask...
I have a listview in my android application, and i want to have a delete button in each item.
I want to show/hide this button by toggling an external button. Is it possible to do this with an animation? Also the animation has to be synchronized on all items.
I know how to do this without animation but with animation i have no clue.
Does anyone know how to do that?
Thanks
If you take a ScrollView that has a LinearLayout inside it. Then by adding rows to it using an inflater for the custom row and inserting each row into the LinerLayout you mock a ListView. It's actually faster for smaller ListViews to do this. Inside your LineraLyout set the android:animateChanges = "true" then add an onClick listener to the button in each row that will remove the view from your LinerLayout you can get the desired effect. It is all in one of the samples on the Android website. If you need source code I can post an example but to see the effect in action look to a sample app I published on Google Play called My Gratitude List that I published to practice some layout effects. Here is the link to the app.
I added a ListView and a Button to a layout.
What I want to do is, when I click the button, the ListView should scroll to a specified item such as the 10th to the top. But I don't want it to scroll too fast like flipping a page.
How can I do this? Can I add a fraction to a ListView? If so, how can this be archived?
i haven't try it but you can use "setSmoothScrollingEnabled(boolean smoothScrollingEnabled)" method of listview.
i think this will help you.
