I am looking for some ideas on how to best achieve this effect. I have two fragments, one containing the map (and all controls) and another fragment that contains my RecyclerView to display the results. In my activity layout I would like to position my map and list fragments exactly how it is shown in this video. The map fragment shall stay aligned with the topmost edge of the list unless the user is actively scrolling the list upwards. The video I recorded should demonstrate what it is I am trying to achieve.
From an explanatory standpoint, I need view and layout ideas. I have already implemented all the necessary callbacks for all user interactions between the two fragments and the activity. One item in particular I am most interested hearing feedback on is how to align two views and then have the lower slide over the view when the user starts scrolling. Notice how the list (when showing) will not scroll downward.
One method I can suggest is to have both the map and the ListView in the same fragment and try this. It's the sliding drawer animation in Play Music.
For the part where touching the map shrinks the list view to a bar on the bottom. I suggest you create animations in the listView to shrink and to expand and call them on event Down and Up respectively. Here is the MotionEvent.

I've seen many examples for implementing a card flip animation when transitioning between two fragments, however I need to implement it on two views within a single fragment. Basically, within a listview row we have some property details.
They the user taps a more button in the lower right, I want to flip the row's view so it shows the actions for that row instead.
I have card_flip_left_in.xml, card_flip_left_out.xml, card_flip_right_in.xml, and card_flip_right_out.xml animations in my Resources/anim folder. I wasn't sure how to proceed beyond this.
So i have this requirement for a custom scroll for a linear layout and i have no idea where to start. The scroll will be like this:
instead of recyclerView items leave the screen, the top most item will remain fixed, and the items will overlap it when scrolled. So instead of scrolling out of the screen, or scrolling into the screen, they will scroll out from the first card and into the first car.
I would seek for advices with alternatives, as i have relatively short time to do it. I would avoid doing a custom layout manager unless really necessary (its tricky to do so).
I want to create a custom listview that scroll horizontally and stacks the last 4 items in the view instead of allowing them to go off screen. The stack should look something like this: . So if a user scrolls all the way to the left they see a regular listview, but as they scroll right, if an item was supposed to go off screen, it is instead stacked behind the last item in the list, with a max of 4 stacks. What's a good basic way to accomplish this? I already found the horizontally scrolling listview library I wanted to use but don't know where to start on the stacking part.
I am new the Android development (3 weeks).
I'd like to create an Activity that allows the user to scroll through a list of items. I'd like only one item to occupy the width/height of the screen at any given time. At the same time, I'd like for the items to be able to scroll smoothly (up/down), similarly to facebook/instagram. During run-time, items will be pushed on top of the stack/list (like a news feed in FB).
What is the best way to accomplish this? What are the pros/cons between using a ListView, LinearLayout (Vertical) items, a List of Buttons added on top of one another? Or should I use Fragments that display on top of one another? How would I implement the ability to display only one item at a given moment?
The answer is to use a ViewPager: http://developer.android.com/reference/android/support/v4/view/ViewPager.html
By default, the motion is horizontal, but there are examples that show how to make it vertical.
I have a ListView and each item contains a TextView displaying a number. I'd like to give my users the ability to change this number while staying on the ListView (as opposed to drilling down into a detailed view by clicking on the list item).
What I'm looking to do is to slide in a layout from the bottom of the screen that covers about half of the screen. I'd like this layout to be OVER the Activity behind it (as opposed to being part of that Activity's layout and simply showing it). I'd also like it to be model (or seem modal). Meaning the Activity behind it can not be focused and manipulated. In this layout I will essentially create a calculator.
What I need help with right now is:
1) How to display a layout over the current Activity
2) How make the background (the Activity) modal
Could someone point me to some tutorials/resources and/or give me a few tips?
use an Animation. here is a small tutorial on them: http://developerlife.com/tutorials/?p=343
initially, the view you want to be modal must be placed where you want it to show up(and visibility set to gone).
use a translate animation to visually move the view from below the screen to halfway up the screen. once the animation starts, set visibility to visible
try disabling all views that the user should not be able to interact with after you have started the animation holding the calculator view
