I have a android gallery and image view in my main layout. When I touch an image in Gallery I display that image in the imageview below. What I am trying to achieve is I want the user to be able to fling the image itself to left or right to go to next or previous image. I have been able to do that also. But at the same time when the user flings to next image I want the Gallery on top also to scroll to next image. How Can I achieve this. Any help will be greatly appreciated.
You will have to use the setSelection method.
if( fling right ){
gallery.setSelection(gallery.getSelectedItemPosition() + 1);
}

I am implementing pinch-zoom on ImageView in my App.I am having an Activity which is holding Gallery view and I am showing my ImageView inside gallery.Independently pich-zoom is working and I am able to handle gallery fling also when image is in normal size But my problem is:
How to fling when Image is in some zoom level.
you can follow this links that adds panning, zoom, and boundary detection to ImageView.
How can I get zoom functionality for images?
Generally Gallery include Two functionality
Zooming current Image showing to User
And swiping to next/previous Image
Issue is when we zoom Image inside a Gallery, it should disable the swipe view. It should only swipe when Zoom Image Drag reach to end.
This post Tell about how to zoom an Image Perfectly. Now you have to take one ViewPager and integrate both
I have a gallery that I use to display some ImageViews. I'd like to know which image in the gallery is currently highlighted/focused.
So far, setOnItemClickListener only fires if I actually click on the images. If I scroll through the images, a new image takes focus. I want to know which image that is.
How can I do this?
Get the images number in the list
Get the image (view) it self
how to center an image from gallery? If i use setSelection()
the gallery didn't are center, she move sometime in left sometime in right.
She move in center only if the image was in extremities or if the selected image was in center.
If i do a second clique the picture go in center, i don't understand why. I use a setOnItemClickListener to change the image.
This is what the behavior of the Gallery.Just Use the classes of the Gallery Customize it which involve CustomGallery CustomAbsSpinner and CustomAdapterView and change the function of Gallery class getCenterOfGallery() as per your requirement.
