I know how I can change the animation between two activities. But how about:
Imagine an activity with one rectangle in the middle. If the user presses on the rectangle and swipe to top, the whole activity should swipe top (with the same speed) and finish if the user has swiped enough. I know how I can change the transitionAnim between two activities but this drives me nuts.
Using Framelayout, setting Homescreenwallpaper behind the content and make the anim on the content could be one solution, right? Are there better ways?
Could someone advise me and/or give me some tipps how I can achieve this?

I have the requirement for what is effectively two activities side by side, allowing the user to scroll from one to the other, and back. I've decided that ViewPager is probably the best way to handle this, but am open to suggestions.
When the activity loads, the left hand view is displayed. I want to indicate to the user that the other view exists, by just scrolling it a small amount to the left and back again (similar to the way it's now common to show that a sliding drawer menu exists).
I've tried a number of things but have yet failed to find a method where both the views scroll smoothly together. Another way of interpretting the requirement is saying I want to programmatically fake a user flicking the page briefly.
Try calling the method fakeDragBy(float)! According to the documentation you need to first call beginFakeDrag() to initiate it and then call endFakeDrag(). This will mantain the ViewPagers default snapping behavior, so once you've revealed the other screen is there you don't have to animate the transition back, simply call endFakeDrag and the ViewPager will correctly snap back to the last screen (As long as you haven't dragged it past the half-way mark).
I have two activities one with some data and the second one, semitrasparent with some buttons on it.
I want the second activity slide over the first one after the swipe gesture.
I've already read about ViewPager and it's not what I am looking for. I want the first activity still being visible over the semitrasparent second one.
I am looking for any suggestions how to do this.
Literally not possible.
The entire point of an Activity is that it fills the ENTIRE screen, and there are never 2 of them shown at the same time, ever.
So you can't swipe to "semi" open one with a slide animation.
To do that, you'll have to use 1 Activity, and multiple Fragments.
So, I'm working on a media player application.
I would like to make something similar to Google Play Music's or SoundCloud's slide up mini-player to full-player UX.
I'm not really sure how to tackle that, though. Is it simply two fragments/views? I can understand how to transition onClick with animations, but how would I go about the fluid dragging?
Yes, it can be done with a fragment, OnTouchListener, and dragging the fragment up. I've done it with a click event and animation with no dragging.
The activity is on the bottom and the container with the fragment placed on top via the xml.
I wouldn't call it expanding though. Its just not fully revealed on screen (i.e. the location is on and off the screen and the fragment isn't actually changing).
I have an activity that displays a camera screen, another one that displays a dynamic list of things, and I would like to slide between them.
The problem is that the ViewPager only allows me to slide between different layouts, without any activity-related effect.
Thanks for your help!
I think that using a ViewPager is what would be the easiest way. But if you don't want to, maybe you can try something like that :
Code something to detect the swipe gesture.
When the swipe gesture is detected, start the second activity whith a slide transition.
I've never done something like that. It's just a though.
I've been trying to figure out how to go about doing this specific task, but I can't quite figure out.
So, I have a ViewPager setup with 2 layouts that work perfectly. In the landing Pager, I have a button. What I'd like to do is, hit that button and the page animate vertically (up) to another layout.
I got the similar movement with starting a new Activity, but the problem with that, is that the title bar gets animated as well. So it doesn't give this fluid motion to the layout above.
I tried several things, but came up short with a lot of crashes.
Then I was thinking of having the landing Pager be a ScrollView and stack both layouts on top of each other, and navigate to a specific id, but came to no avail.
Does what I'm saying making sense? How should I go about creating something like this?
So to summarize.
Land on a page where you can swipe to one additional page (left).
Be able to hit a Button (on landing page) and animate up (vertically) to another layout.
All of this while having a static title bar.
Thanks in advance.
