I need to implement pagination in my android app. I have multiple textviews in my android application. I need to display it as pages in my UI.
Am adding textview dynamically to my scrollview layout. Inside my scrollview there may more than one Textviews with dynamically loaded texts with different height. I need to implement pagination with this. How can i achieve this, please provide me some ideas or working codes.
Maybe user ViewPager? It provide you pages where you can apply fragment with any view you want. You can use it on part of screen.

I want to create a scroll view with pages that can be scrolled vertically and horizontally as well.
The scroller should be just like a slideshow on a website, to slide between images (content). Something like ScrollView, but to stop at a certain point when scrolled.
I am using this in Xamarin.Forms, so I'll need to create a custom renderer (Android) and set the content of the pages from Forms.
I tried ViewPagers, but I want to be able to set the content from Forms page, not from predefined layouts...
I just couldn't find a clear example/tutorial so I can understand how to approach this problem. I also think about overriding some methods from ScrollViewRenderer class, to intercept and only slide to a certain point, but have no idea which methods and properties to change.
Something like CarouselPage on XF, which can be used inside a layout.
Any help or examples would really be appreciated. Thanks!
I'm searching for 2 days for a solution for this problem.
I would like to have 2 or more different CardViews which are inflated into a single RecyclerView.
For instance, one card with just text and another with text and an image.
At the moment I have functional code which works with the CardViews independently, but I am unsure of how to inflate the two simultaneously.
The code I have is based off of this Tuts+ tutorial.
Please could someone offer a solution or, alternatively, a better way to do it?
CardView is an advanced View widget that allows you to add other Views onto it. Thus, for your situation, simply add another CardView in your layout file the same manner you added the initial CardView.
Hope this helps.
I have a list view in which I want each list item will contain images. But the images will be displayed one at a time. SO, at a time for every list item only one image will be displayed. To view other images in the list item,one has to swipe horizontally. Is there any inbuilt widget that handles this in android?
EDIT1
My List item not only has Image but it also contains other views like textview, seekbar etc. So each list item will contain Image, textview, seekbar etc but the majority of the space will be occupied by the Image. Now, for each list item, when the image is swiped horizontally, another image has to be downloaded from a ulr and displayed.
EDIT2
I did a bit of research on ViewPager but many references like the answers here and this blog seem to suggest that using ViewPager inside a listview is not a good idea. Why is that? If it is not a good idea, what is a good alternative?
This problem can be solved by using ViewPager.
Link: http://developer.android.com/training/animation/screen-slide.html
ViewPager(for swiping between views) + UniversalImageLoader(for loading images from URLs, with caching etc)
If it is not, what is a good alternative?
I think you should use RecyclerView with LinearLayoutManager.HORIZONTAL. All things like recycling the views, view holder design pattern can be done easily with it and it is a new widget that google introduced and you can use it instead of ListView + ViewPager. because as you suggested it is not recommended to use viewpager inside listview. Although you can use horizontalScrollView but it dose not recycle the view. Other third party library like this exist but I recommend you use RecyclerView with LinearLayoutManager.HORIZONTAL because it is from google and it is normally tested more than people library. And another thing is you can use other layout manager like GridLayoutManager or having for example 3 rows that swiping horizontally or other good effects like adding animation and .... that google provided with RecyclerView.
For downloading the images you can use Picasso,Volley, Universal Image Loader or a lot of other libraries that exist.
Happy Coding :-)
Not sure I'm following you, but rather than a ListView wouldn't it be simpler to use ViewPager with simple Fragment that wraps a single image at a time. That way you get horizontal swiping "for free".
Do you just want swipe to change images? Or do you want the images to scroll as you swipe? For the former, you can just use a GestureDetector. For the latter you would probably use a ViewPager. See http://developer.android.com/training/animation/screen-slide.html
I have achieved the same functionality by using ViewPager, you can either put the SeekBar and TextView in the Fragment class off which you are gonna make multiple instances for each item and add to the pageradapter,
You can also add the TextView and SeekBar above the ViewPager Layout in your main fragment layout file and change the text and data on seekbar on viewpager's on item change listener, this looks more neat and this is the approach i've used
I have implemented simple database android application.In which I have displayed list of name and images.But if data is more then ten then table layout is not scrolling vertically.
Is it possible to implement vertical scrolling without using scrollview?
If possible then please provide me some reference.
Thanks in advance.
Why do you want to do it without using ScrollView? You can simply wrap your TableLayout inside a ScrollView to add the functionality.
I've always used ScrollView so I can't really give you a way to do this without using it.
Random link off Google that explains it pretty well: http://huuah.com/using-tablelayout-on-android/
As #Klaus said, you have to implement a ScrollView. Nonetheless, you can set
android:scrollbars="#null"
in the XML resource and in that way the scrollbar will be "invisible"
Hi
Here is a good article http://blog.sptechnolab.com/2011/02/01/android/android-custom-listview-items-and-adapters/. It is in LinearLayout but is someone write comment over there then i can convert the layout file into TableLayout.
I´m writing an application for Android in which I have a character that I must dress with multiple items, such as clothes, hairs, hats, earrings, etc. and on one side of the screen I need to have a container with many items inside that are available for use.
My problem is that I haven´t found any object that lets me do this simple task in android, I need it to be scrollable, and resizeable so I can place it on the right of the screen, the objects i need to add are Imageviews.
I accomplished this on iPhone with a UIScrollView but it seems that it't not that simple with Android.
Thank you.
you will use a ScrollView too, but you need embed a container of your images, like a Layout or Webview inside your ScrollView.
