In one part of my app, I'm trying to make a gallery of photos that you can browser through. I want to have a snapping effect similar to the Gallery class. I want it to have a snapping effect every time you swipe from one image to the next in the list. This would be similar to the Gallery app where you browser through photos, or who you swipe through your gallery of apps. Every time you swipe, it has a "snapping" effect. What would be the easiest way to do this?
I know in the newer Android APIs the Gallery deprecated, so that is out of the question.
You want ViewPager. It's included in the compatibility package and described in this Android Developers blog post.

In the Google Photos app, in the photos tab, you can long-click a picture to select. If you keep holding the screen you can drag to highlight additional pictures to perform an action upon. From a coding standpoint how can I implement this functionality in both a list and grid view. I haven't been able to find any sample code.
You have severals libraries existing that do the heavy lifting for you.
I'm using : https://github.com/afollestad/drag-select-recyclerview
and it's working great.
So i got a lot of solutions online but none of them were simple and complete. First i tried using imageview and adding external libraries for zooming etc. but i couldn't find one which had all the functionality we see in a gallery app without being extremely slow. I read something about canvas though don't know what it is. I also found "zooming a view" in android official tutorial but it was just a single tap zoom. So which is the best solution (in terms of functionality and speed) for this: I want an activity to show just a single image such that the user can zoom/rotate/pan it as its gonna contain text that the user needs to be able to read. So basically just like a gallery app. Is it possible to call on the gallery app activity to display this image? Why doesnt android have better support to do this? What is the best way you would suggest.
I am posting this question because I never worked on this and I am not aware which component is used to implement such functionality.
See this screen-shot. This is an sample image. It is not my work, this is taken from Google Images:
Now on application startup I am reading Android sd card and updating my database. In the meantime, I am using ProgressDialog like this
Now what I want is to show 5 image slides. Not Image slide I want a single colour backgroung and the text should have to be change every two seconds on the same backgroung with five small circles I downside.
Now I am not able to get what is it. A image slide show or other native component. I asked in chat rooms they asked me to post here.
If it can happen without image it will be better because there is a lot of complexities with different device sizes.
How can I implement this?
Try with android smartimageview or with Viewflow
I'm wondering how to implement gallery of screenshots like Google Play (Android Market). If i use typical Gallery, the problem is the first item of gallery is at the center(it has big big space at the beginning and the same at the end). I tried some horizontal listview but it seem has problem with scrolling when i push my horizontal listview in another scrollview link. In Google Play, the "gallery" doesn't have space at the beginning.
Thanks in advance.
use a ViewPager. it's used extensively in Google's in-house apps and works quite well for horizontal paging. it's also a pretty excellent replacement for TabHost.
Gallery is actually deprecated in favor of ViewPager.
Actually i finished my project long ago and forgot close question. Using this Android: Create an image Viewer using ViewPager.
For future guests, you can see another training from Android Developer about ViewPager here:
Displaying Bitmaps in Your UI
I would like to know if it is possible to do the following:
I would like to create sort of a slideshow element for my app that when a user swipes their finger of the image, it will take them to the next image. If they click on the image, it will take them to a link. Is this possible with Android? This would have to be updated from a link outside of the project of course. So it would have to be on our main Web site. The code cannot be developed in eclipse, since it will be targeting new events.
Thanks
Sounds like you want a Gallery or a ViewFlipper, with some ImageViews with click handlers that launch ACTION_VIEW intents with urls.
