I am trying to get images from Internet. (i can't show my code here). i AM storing a few images in a list and displaying them in an imageview each image after tapping other.
However, I want to make a slide of these images.
It's just a basic 'move to next picture' by sliding your finger on the screen.
Same as it would be in the phone photo gallery.
It's just to navigate through the images.
At the moment the image is going to the next one by the user tapping on the screen. But in this manner we can't go to the previous image. This is why we need to change the navigation to sliding a finger on the screen.
I have used View Flipper and ViewPager but how am i suppose to add images to these views after getting from internet each time.
Best Regards

I just started with Android Studio and I'm sure this question was maybe asked but:
I have a small app with an ImageView in the center.
Below, I have 2 buttons. All I want is this:
When one button is touched, I want the camera roll to appear, so when a photo is selected, the photo is placed inside the ImageView.
When the other button is touched, I want the user to take a photo and the photo needs to appear in the imageView.
Is there a tutorial on this specific issue?

I followed this link http://www.androidbegin.com/tutorial/android-implementing-viewpager-into-gridview-tutorial/ to obtain gridview in viewpager. But my problem is that the image displayed as full screen in viewpager appear to be cut in gridview window. I want the image that appear as full screen should also appear in gridview window. In other words, the image displayed as full screen should appear as whole in small size image in gridview window.I meant something like the images displayed in this question link...Order of images in Grid View in Android
I just start with programming, so please give some explanations, or it will be great if you also give some codes :)
I suggest you have a look at ImageView.ScaleType. It it will show you how the image should be scaled, cropped, etc. to be displayed in an ImageView.
My app consists of five different fragments where the user can slide from one to another.
I have applied the stack (Official Google Animation) to the fragments so the layout looks more appealing when transitioning from one page to another. I went ahead and made some changes, but when swiping you an see a black background so I had changed the default background in my styles.xml to a pre-fixed image. But I wish to apply the wallpaper of the system. For example I'm on my home-screen and I have lets say a picture of a cat as my wallpaper, and when I open my app, and scroll across screens I want the background to display the system wallpaper, aka the cat picture.
How can I go about achieving this?
I have searched on this but nothing is showing up, I've tried adding a colour item to colors.xml and setting the hex value to #00000000 and applying this to the background, but when sliding across the fragments, there is no transparency, instead it's black.
It seems so I can use this code -
WallpaperManager wallpaperManager = WallpaperManager.getInstance(this);
Drawable wallpaperDrawable = wallpaperManager.getDrawable();
But how can I apply this as a background to all of my fragments? I'm aware that it must be applied in the fragmentlauncher class where all my fragments are launched from.
I have a ListView in my application that has both text and images in it on each row. Now, when the row is clicked I'd like to zoom the image to fill the screen. On the next click it should collapse to it's original size.
What I'm looking for is something similar to Lightbox. When the image is clicked it expands.
I have access to the ImageView. What do I need to do to it to achieve this kind of effect?
If you want to zoom in/out view you can use scale animation. I recommend to watch Chet Haase tutorials called DevBytes: View Animations
In my Android app I have a gallery which contains some TextViews. I realized that some users don't understand that they can scroll that gallery although the previous and next TextViews are partially visible. So I put an ImageView with a horizontal arrow under the gallery.
Now the users try to drag the arrow. Is it possible to redirect the touch event from the ImageView to the gallery so that dragging it would scroll the gallery?
Thanks in advance,
Fri
The simplest thing (if you don't mind scrolling one item at a time) is to detect the direction of the touch event on the arrow and then dispatchSetSelected(boolean selected) on the gallery... I believe that will work. after the user does that once, they will probably intuit that they can then just drag the gallery. Of course if you want to measure the touch event speed and do the calculation for how far to scroll based on that, you can do that too... but that seems like a lot of unnecessary trouble.
