I'm working on image multi touch events, that have an image with touchEvents like googleMaps's touchEvents( pinchZoom and move togather with 2 fingers ), I tried GestureImageView and cusomized it and could implement that. but I'm not sure it is correct way or there is another method for it.Is there any way to do that ?
also I want to show different parts of the large image by clicking on each part and show theme so that it seams that camera moves view on the image.
Is there any library or any tools for this purpose in android?
I will be appreciate if help me.
Thank you.

I am going to create an android app where I can click on icons and have them layered on top of a picture/layer, and be able to move those around on top of that picture or layer using my finger etc.
I'd like to know if there's anything in android animations that can help me do this or if there's some way of doing this like the html < map >
If you look at this, would be helpful to you.
Using ImageView may solve your issue.

Much better than the offered alternatives here IMHO
I need to build a component to view large images.
I cannot put the ImageView in a ScrollView because I will need to be handle other touch events on the image.
The ideal would be to build a "viewer"
with an horizontal handle
and a vertical handle
that enable to move where the picture is centered so that I can scroll the image using the handles without touching the picture itself.
I would like to achieve something like in the following picture, I have researched but I was not able to find any Android API or other component/library that I could use.
Thank you very much for any suggestion.
Best thing I can think of is use two custom scrollbars for the horizontal and vertical scroll. In an onChange() function you can change the crop area on the master image and display the cropped image. Depedning on how it is done you can get a slide effect going for the image.
I want to create an image auto scrolling for an outer-space type of game. To make it more exact, I want to load 2 background image that uses a single image occupying the whole screen and auto-scroll it alternatively to create an animation that the background image is moving. Don't get confused with auto scrolling and and shifting to another image automatically. I really meant auto scrolling like moving background using 1 image.
I did some research but what I saw are segments of java codes that made me confused. If possible can anyone provide me an example? From loading the image from xml (should I use an imageview with this? or just set the background image of the layout?) and how I should process it in java code to make an image autoscrolling.
Any ideas guys? Thanks! Sorry for asking too much.
User can select some images to the screen, and be able to select/drag/move/zoom/rotate each image. When an image is selected, it will have a blue border. And user can also bring an image to the front or background.
Here is sample picture in the following: there are two images(girls) on a star-background. The top one has been selected(it has a blue border).
I don't know have to implement it. For several days of learning, I can now drag/move/zoom/rotate a single image(inside an imageview, and scaled by matrix). But I don't know how to handle multi-images.
I want to know:
Is it still a good idea to use ImageView(for each image), or what classes should I use?
How to implement the orders? (so I can bring them to front or background)
How to determine which image has been selected
How to find and draw the border of selected image?
For now, I just know how to use ImageView, but I'm not sure if I can use it to implement this task. Please give me some advices, thanks !
Drawing everything directly onto a Canvas is one way of doing it. There is an article that covers the basics of using a Canvas. You can read it HERE
There is one major downside in doing this - you have to handle all the input events by yourself. The API won't tell you which image has been clicked, or dragged. You'll have to implement that by yourself.
