Using github.com/TonicArtos/StickyGridHeaders library for placing headers in gridview and refer this article http://www.programering.com/a/MjN0ITMwATU.html where is the demo as what are u expecting.
The thing is that you are not supposed to add a scrollable view into another scrollable view. Both ListView and GridView are scrollable, so that just leads to trouble. I suspect that the Dropbox app does not use a GridView, but multiple LinearLayouts, that's at least what I would do. You just can not use an adapter in that case, but need to add the layouts and elements programmatically.

I want a layout that will display images without knowing how many. First i thought of a ScrollView, but don't know how to add different images to it. How can that be done? Or is there any other solution?
How can that be done?
Have the ScrollView wrap around a vertical LinearLayout, into which you add your ImageView widgets.
Or is there any other solution?
ListView. GridView. RecyclerView. ViewPager. And so on.
Depending on how you want to display the images, you can also use GridView : Grid View Android Developpers
There is an example : Gridview with two columns and auto resized images
You don't need to use ScrollView or know the amount of images you're gonna show. Just use a ListView with an ArrayAdapter that binds a List of Bitmaps (images) to your ListView (each item of your ListView is an ImageView). Each time you add a new image to your list, just call notifyDataSetChanged() method of your adapter, that's gonna update your ListView.
Just google for a relevant tutorial. You're gonna see lots of examples.
Need some help!!..
I'm try to implement a list view with two images in the initial screen, after scrolling other images can be seen.
Can you suggest anyway to implement it!
Use can achieve it by creating custom adapter for list view. Have a look :-

You need to do some updation like removing text view from custom list layout.
I want to implement the below image in android ,
I have used Relative Layout to display content and Recycler view to display comments but I want both under one scroll while my problem is recycler view is creating another scroll.
I also thought to add a layout dynamically but in that every layout I have to implement click listener for every child , which is not good for performance
What could be the best way to implement it
You can make a ListView where row contains Comments part and add Image as a Header of that ListView.
The other way is to create a Custom Adapter and include Image and Comments as a single row of a ListView
For implementing a click event on each item you can refer to this answer
Why don't you use a ListView with custom elements in it (that look like the comments on the picture) instead of the RecyclerView
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
How to do a layout like this? I currently use a listActivity and I need the same experience with this kind of layout.
You can use Staggered Grid View library. Also check and Quilt View. This is what you need.
To get this effect, you should create two list views and link the scrolls of both lists.
Define a OnScrollListener on both listviews and when "onScroll()", move programatically the other list. I think if all images are cached you shouldn't have delays.
You can use Staggered Grid View library. But there you need to mention height of each image pragmatically to set height of list view. Else when you scroll to end and come back to top, the alignment of images on top will get disturbed
You have to use GridView
You can refer this or this.
