I have been looking for a solution for this for a while now, What I'm trying to do is an application with drag animation like Tinder, the difference is that I have 3 images at once, one below the other and all of them are in ScrollView. My problem is that when I'm touching to move it up and down the ScrollView takes place, I can move it freely left and right but if I move it up/down even by one pixel I lose it. I've tried to make custom ScrollView that disables the touch of it when I touch the other View's with no luck :(, I thought maybe try and make the views that I want to drag to be at the top of the views with the Z-index and I couldn't find anything about it. I saw some answers like the dispatchTouchEvent and intercepTouch or something like this but I didnt understant how to work with it.
Sorry for my English, Thank you!
Found the answer, I used getParent of the view until I get to the scrollview as parent, and used requestDisallowInterceptTouchEvent(true) that solved it!

I have a horizontal slider in my app, and I want to make it so that if you have the slider selected, you can do the two-fingered swipe up or down gesture from anywhere on the screen (The scroll up or down gesture) to move the slider left or right. I haven't been able to find anything through google about how to change vertical swipe behavior for Talkback and was wondering if there was in fact a way to change this.
I'd really suggest not doing this, it isn't how Android works so it will confuse your users, and be a big source of bugs as any behavior like this can cause touch errors on completely separate views. I just fixed a problem on something similar in my company's app.
But if you really want to do this- your root ViewGroup needs to intercept touch events if there are two fingers down and it moves far enough to qualify. Read https://developer.android.com/training/gestures/viewgroup#intercept for an explanation of how a parent view group can steal touch events from the child. This is the same way ScrollView works to scroll its contents. In fact, looking up the AOSP implementation of ScrollView would give you good example code.
In my android app I am not able to move vertically when I put a map inside a Scrollview and if I am using other layouts then the items at the bottom are not visible.I had seen all the solutions provided before my question but couldn't found any appropriate solution..Thanks in advance if anybody could be able provide me solution who to do it ?
Scroll view by default only scrolls vertically. Have a look at this answer, it might solve your problem.
I need some help, i want the android scrollview animation effect....
Basically when the someone click on the textview of linearlayout in scrollview another horizontal view should come in.
Here is the pic....
What you could do is setup ontouch() on the textview. once you touch it then you would make the layout visible with setVisiblity(). you could even add in a animation to make it more professional.
You would probably get a bug if you didnt make every other view GONE, when you touch a new textview.
I like this idea and I might work around with it myself!
Good Luck
I am searching for an easy way to implement a view flipping like used in several occasions by google apps.
Behaviour should be like this: OnScroll the view should move to the side and show the content of the next page. If scrolled far enough the view should move smoothly into position (after lifting your finger) and snap into place. If not scrolled far enough and the finger is lifted, the original view should smoothly move to the original view and snap into place.
I search around and didn't figure out a easy way.
So I though about something like this:
Hide the ScrollBars of the horizontal ScrollView.
Set the scrollView position manually according to the position I get from a GestureDetector.
I am pretty sure that this way works. But it seems to complicated to me, because there are to many things that have to be programmed. Like the animation (Smooth acceleration, deceleration, snap), Gesture, calculation of the actual position....
So my Question: Am I on the right way or is there an easier approach? Did I miss something during I searched for a solution? Is this function already implemented by android or does it really have to be done by myself?
Look for this tutorial. Also if you try to search here, on SO, you will find thousands of similar question with lots of different solutions. You can choose one, that will useful for you.
I used buttons in HorizontalScrollView. normally when scroll right, after the last
button I have to scroll left. But I want to know when scroll right
after the last button it should show the first button. not want to
scroll left.
just as circle.
thanks
I don't know how to do that trick with horizontalScrollView, i thought that it's impossible, but i know one widget, that maybe can help you

unfortunatly, it's only vertical, and you can't put buttons into it. I tried to make it horizontal, but failed. Maybe, if you will need, you'll get more luck
