I want to implement a lock screen where the user has to swipe up an image to reveal the app lock screen. I know how to animate views, but how do I animate them based on user input? (i.e. not just swipe up, user should be able to pull the image along)
I really don't know the term for this action so I've been stumped trying to search for it. I tried searching google in many ways but no results
You can use GestureDetector to detect user's gesture and then you need to animation views.Use below links for ref

I am working on an app in which i want to swipe image horizontally and while making swiping to half it would do some action and it would regain its original position. this is to be done in both ways left and right swipe.for an example gmail app uses this, in which when we swipe it half and left it, it will regain its same position. but in similar terms i also want to make some function call. please suggest me what to do.
for this i have tried something swipe features but i am not getting it properly.
If I got ur question correct, this is the solution

In my app, I want the user to be able to follow this list of instructions to be able to put a link to their installed android apps into a widget that I am creating.
In the widget, when the user taps the widget it opens up a new activity which contains all of their apps. To add new app links to that activity, I want the user to be able to pull out a kind of scrolling tab that would hold a list of all of their applications they have on their device (I already know how to do this). The user would then be able to press and hold on a app from that listview and then drag it into the droppable area in the widget that would hold their app. Please note the picture below to get a better idea of what I mean (sorry for poor quality):
How could I turn a listview object into something that is able to do this? I would have to make the listview have a touch listener attribute and then make the droppable area have a drag event, that much I am sure of (somewhat from just looking around on how to make things drag and droppable).
How could I do this? Any ideas or comments on improvements are appreciated!
You could use setOnItemLongClickListener to set a listener waiting for a long click then when it is fired begin the drag process.
In my web application there is an image gallery that uses swipe events to navigate to the next or previous pictures.
If a user zooms in to a particular image and tries to swipe to go to the next or previous picture, the whole page moves in addition to the swipe event being triggered, which creates a bad user experience. Note, this is a non issue, as long as the user is zoomed out all the way, however, I wouldn't want to limit the user in that way.
I was wondering if someone ever experienced this problem and has any suggestion as to how to troubleshoot this?
Swipe Event
$('.slideshowFrame').swipeleft(function () {
galleryIndex = ++galleryIndex%gallery.itemCount; //update index
$('.gallery-img-container').attr("src", gallery.item[galleryIndex].image);
});
I appreciate any suggestion, many thanks in advance!
I have done live user testing for a list in my app, and have come to an interesting puzzle.
A list, specifically a single-column table in iOS, may often have a swipe right gesture for more actions, like the twitter app and mail app, and a million other apps. But when important functionality is embedded in the UI beyond that action, and a user cannot figure it out, the only thing that comes to mind to alleviate that is something like the accessory button, ie. a right-pointing triangle or chevron button.
There is probably another way but it's not coming to me. Maybe making the rows taller than normal?
This was meant as a comment but was rejected as too-long.
So after thinking more about this, the ideal solution is a visual clue, rather than painfully obvious text saying "swipe a row for more options". Perhaps when a list (UITableView, etc) is shown and rows (UITableViewCell, etc) are created and added, then as they appear an animation begins of the main visible content sliding into place in the OPPOSITE direction of the desired swipe animation, with a minimal visual indicator afterward, reminding the user that the content is moveable!
Sound good? Optionally, immediately before the animation begins, any underlying content may be shown for a split second (if its supposed to appear underneath). Sweet!
I have submit button. When I do click or tap below a submit button, it should be able to recognize the gesture by programmatically in android. How could I do this?
Do I need to download anything based on Gestures? Else what should I do for this Gestures?
And, like a Gesture point- If I draw a line using Gesture concept or anything, gesture should perform its actions . After I draw a line, it should be able to open another screen. It must be able to display the last page.
maybe you need this android gestures.
