I need to have a set of Image views on a Linear Layout. &
==> onClick of an ImageView, I want to turn the Image to the back(Like Flipping Effect) & show another Image.
==> Again on click of that Image or another Image, I want to apply the same effect for that Image View & the Previous Imageview must come to the default position.
---> I just checked the FLIP ANIMATION in Android. But it is flipping the total view.
So I Just need How to flip an Image view in the same manner, with support from Android v2.2 & up
I think it is quite complicated but it is interesting & need some help how to achieve this as I am just learning the Android(& Coding).
Thanks.!!!
You can use this small library to do that :

I am developing Android application for book. I create total images for book is one hundred. In the app two buttons present one is previous button and second is next button. The previous button and next move images forward and back correctly. But now I want to implement zooming effect for image. But the text are some smalls not seen correctly. Please help. Thank you
Below are the options available for implementing zoom in-out effect in android Imageview.
How to implement zoom effect for image view in android?
Android imageView Zoom-in and Zoom-Out

Much better than the offered alternatives here IMHO
I'm building an app where I want to swipe images as though they were photos on a stack. In other words, if I swipe the top image I want it to animate moving in the direction of the swipe and have the next image underneath it visible the whole time. To accomplish this, I'm using a FrameLayout and two ImageView containers. I'm just alternating which one is on top. Meanwhile, as soon as a swipe occurs, the next image is loaded into the ImageView at the back using setBackground(drawable). My problem is that the ImageView at the back doesn't update it's image until I call bringToFront() on it, which means that as the top ImageView is animating, the image underneath is incorrect until the animation completes, at which point it abruptly changes to the correct image. I've tried calling invalidate() on the rear ImageView after setBackground(drawable) but this doesn't work. Anyone have any ideas on how I can get the image to update while it's behind?
UPDATE: Turns out I'm just not very on it today. I was updating the wrong ImageView and because the image loading was being done off the network, there was just enough lag to make me think it was happening after the animation completed.
Sounds to me like you wanna do something like an Image Slider.
There are great libraries existing for this purpose, this one for example:
https://github.com/daimajia/AndroidImageSlider
If you don't wanna use this, here are some tips:
Images on ImageViews are set with setImageDrawable(Drawable)
When your animation starts, set the new Image to your ImageView behind and slide the visible one away.
When the visible ImageViewhas slided away, set it's visibility to GONEand move it behind the second ImageView
Do this for every time a new image is loaded.
This should actually work.
You need a "ViewPager"
https://developer.android.com/training/animation/screen-slide.html
It has all the necessary handles to accommodate "N" number of images - also supports multiple swipe animations - default handlers - efficient memory management - prefetching - you are all in for a feast with this !!
Just make sure you get the "ImageView" in the layout of the "pages" you wish to develop on the "ViewPager".
Is it possible to have one picture as a panorama background of a viewpager, without having to cut the image into 3 and put each of the 3 images as a background for each of the different views?
Like the home screen of android.
You want a horzontal Parallax .
this library should to the trick, or at least get you on track.
I'm trying to create a stacked image gallery, this is a gallery on which all the pictures are overlaying each other in a stack(or pile), for example: a card pile, and the user would be able to see and touch just the upper image and to flip/throw it out of the screen(with translate animation). After throwing the first picture the user will see the second picture that was hidden underneath the first one and so on.
I didn't find a similar gallery in other apps except to "weheartpics" (for Iphone off course)
The line of solution that I'm following now is to create a FrameLayout, adding some overlaying pictures on it, to delete the upper picture when the user touch it(instead of throw it out of screen).
Use StackView, available on API Level 11 and higher.
Why not use a ViewPager and flip through your images from left to right? You can then utilize FragmentStatePagerAdapter to prefetch and cache your images as use flips through these
All right - here's another way:
Add ViewSwitcher with 2 ImageViews
Since you can't use drag and drop library look for some alternatives but generally you want implement dragging the top image. Hopefully that will expose the hidden image but if not you will have to swap images when the drag starts
Implement gesture performed listener to listen for the flick events on the top image
When image is flicked away:
a. Swap image views in ViewSwitcher (if not swapped already for the drag-n-drop)
b. Pre-load next image into hidden ImageView
Otherwise return top image into original location (don't load anything into hidden ImageView)
Ok, the solution for that problem was to use frameLayout and to add to it imageView from the code. It's easy to apply animations on the images and to remove/add them after the animation begins.
I want to apply drag,zoom in/out,rotate using multitouch to two images .one
image is placed on the top of the other. after applying these action
Create a image
from above two images after
changes made by applying actions.
I succeed in apply zoom/drag to top image ,created new image from that.
main problem is
1.How to apply action to two images, one image at a time ?
2.How to switch to another image from currently showing image
(which layout I should use)?
3.How user can have a facility to rotate or zoom a image using multitouch ?
What I am missing, Sorry for the list -:)
You need to keep the transformation done to Bitmap1 and apply it again to Bitmap2. for example you can use a Matrix calculated using touch events in order to apply it to the two Bitmaps.
I am not sure to uderstand what you want to do. What i understand is: you've got multiple imageview (that can be composed of 2 images placed on top of another) floating on the layout and you want to select one of them to resize / rotate it.
In order to do that you can simply use the ontouch event of an imageView.
Rotate + zoom with multitouch is not easy in Android, lots of code have to be written in order to make it work nicely. I suggest you to use an existing library. I used this one and it worked like a charm:
https://github.com/lukehutch/android-multitouch-controller
You can see in the sample provided http://code.google.com/p/android-multitouch-controller/source/browse/trunk/demo/MTPhotoSortr/src/org/metalev/multitouch/photosortr/PhotoSortrView.java that you can retreive at any time the new center, angle, and scale ratio of the updated images in mImages(i).getCenterX(), mImages(i).getAngle(), mImages(i).getScaleX(), ...
Using this values you can replicate the transformations (rotation, scaling, translation) on another Bitmap.
