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 am building an android app. I am new to this, I found out an interesting activity UI development, But I don't know how to describe that property properly in android terms-(I SINCERELY APOLOGIZE FOR THAT ).I am adding a video, Please consider it.Free Flowing multi-directional Smooth scrollable android overlay UI (Please turn on the subtitles on)
How to have that kind of UI overlay suppose I want to display a large image or file with multiple clickable buttons on it[I have already tried various Image loading libraries to load big size images and to make that Multidirectional scrollable].But that's not the exact thing which I want (like you can see the above mentioned reference).
So how can I execute that?
Thank you In advance for considering your time.
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.
Hi i have a app contain 3 page. and i want to set one page as background like android home screen. I search in google and i found this and this
tutorial's but i couldn't use it for my target can anyone show me another better example thanks.
i mean How can i create app like android home screen which have one picture for 5 pages background (in my phone).
at last i found my answer and that was so simpler that i think.
that was not a live wallpaper that was simple trick using scroolview for background of main layout and listen to onPageScrollStateChanged.
that's it.
I have a scenario which I think is pretty common in Android applications. I know partial attempts of solving the issue were made, but until now I have not stumbled upon the full implementation. I intend to try to implement such component and open source it afterwards, but I need your help in its design.
So basically my case is the following: I have list view showing image loaded from the web and text per each row. I want to lazily load the images, placing default for each image and substituting it with the real one only when the image is downloaded. I also want to keep image cache avoiding the need to download the images multiple times in short period.
Up to now I have found several implementations that are partially working including:
Tom van Zummeren's implementation of similar component with several well known problems
Jeremy Wadsack's refinement of the concept, which is more or less working
Lazy drawables source forge project.
I also saw several stackoverflow questions regarding the problem: 1, 2, 3
However I have one more requirement which makes my task a bit more complex: I allow the user of my application to affiliate himself with some of the images. I want to load the new images associated to the user whenever the user navigates to the home screen. From it he should be able to go see his images, even before they have all been downloaded and in this case again default placeholders should be visible (Note the cross screen transition). Such use cases are:
An app listing user's youtube videos
An app for facebook - consider the images of friends
An app serving news that supports user's favorites etc
Note that I want to start fetching the new data related to the user on the home screen to provide better user experience. I will keep the user-related data stored locally forever.
The question
So my basic question is what approach should I use for the implementation of the image downloading? I know that the Android manuals say Service should be used only when I want to execute task even when application is not running. On the other side I will start the image downloading on the home screen and link the downloads to UI elements just when the user navigates to the new screen (Activity) - user-related list view and I do not know how to achieve that with AsyncTask (not that I have a very precise idea how to do it with Service either).
Any suggestion will be greatly appreciated, including links.
Universal Image Downloader is a good library which helps you to do image downloading in background with your settings.
It has so many features that you can implement at your own way.
I'm almost a complete beginner at programming (only did some basic a long time ago).
I want to learn how to make Android apps. My goal is to make a simple app that would be some kind of a picture gallery with a slideshow function.
The app would for example integrate ten pictures, there would be two arrows at the bottom of the screen to switch to the next (or previous) picture.
That's about it for a start.
Would any one be kind enough to list the main steps to follow in order to make this app ?
So far I'm learning the basics through various tutorials, but I'm kind of struggling...
Thanks in advance !
Make main activity that contains ImageView and two buttons
Make function that loads images into array or list
Implement listeners for button clicks
Is that enough or You want me to write more about this ?
