How do i implement android style left and right swipe using libgdx? (ex:flipping through imgaes)
I read about GuesterDetector and testcase http://code.google.com/p/libgdx/source/browse/trunk/tests/gdx-tests/src/com/badlogic/gdx/tests/GestureDetectorTest.java?r=2641.
But i am not sure once after guester identfied how to implement android style left and right swipe and also how to distinguish between left and right swipe with in fling method.
Implementing using adroid API is stright forward android Swipe event in listview inside tab widget understood admob example to implement native call backs, but integrating this seems not stright forward in this case.
Either way, Please let me know if some one experience with that.
From that example, you are wanting to use the fling method. To detect horizontal direction, check the velocityX -- positive means a swipe to the right (and you'll want to scroll your images to the left).

the lazy swipe app opens when user swipes from bottom left corner of the screen diagonally. how is this done? how lazy swipe app is only seen as an arc, and not on the whole screen? I want to make an app like that? please tell me how should I start to make that kind of swipe gesture?
I donw know the app, but there are serval ways to do that.
basically you have to override onInterceptTouchEvent() and onTouchEvent() for your View
or
you can override Activity.onTouchEvent() to let the activity intercept all touch events.
Have a look here:
https://developer.android.com/training/gestures/viewgroup.html
Update:
After reviewing LazySwipe: Lazy Swipe is using the same mechanism / android api as Facebook chats heads. It's not an activity. Basically its a Service. Here is a discussion and implementation. There are also libraries on Github (I have never used that one).
But as you see it's not an Activiy, hence you can not use Activity.onTouch(). However, you can display and interact any regular View or ViewGroup. Therefore, overriding ViewGoroup.onInterceptTouchEvent() and ViewGorup.onTouchEvent() is possible. So yes, you can detect Swipe gestures.
There are alredy some gesture detectors build in on Android that you can use. Have a look here: https://developer.android.com/training/gestures/scroll.html
I have created a swipe app using jQM. it is working well.
But this swipe event performs after the sliding from left to right is completed. What i want is when user slides at the same time menu appear like sliding view is this possible.
JQM 1.3.2 has three swipe events that can be modified in many ways.
From their docs: http://api.jquerymobile.com/swipe/
Triggered when a horizontal drag of 30px or more (and less than 75px vertically) occurs within 1 second duration but these can be configured:
The swipe event can also be extend to add your own logic or
functionality. The following methods can be extended:
I would think you want to modify "$.event.special.swipe.start"
I am surprised that your event does not trigger quicker. Default settings state that all they need to do is move 30px in 1 sec. That is like the width of a pinky finger movement.
PS - while this may not be the "best answer." I really just did not want to type all this in the comments!
Good Luck! Hope this points you in the right direction.
I need to implement a swipe gesture using two finger touch input on my ListView from right to left and vice-versa, but it should work exactly like an app named Clean Master who applied this under its "History" section (check the image) for going from Cache to Residual files (but using sinlgle touch input and i want to implement this using two finger touch input). If you've used this app, can you please tell me how to implement this. I've no idea being new to this concept. Please help me learn.
Is this what you need? Its a library called swipe listview.Its so easy to use and have customization options.
I don't want to reinvent the wheel and this has been obviously already been done by Google in the Gmail app. I want to achieve effect identical to the finger slide message remove from gmail. It's also achieved in notofication bar in (you can remove notification by sliding it left or right)
I was wondering if I could get pointed in the right direction. Maybe this is described somewhere in google developers site.
What's most important I need it for API 7+.
You'll have to implement two different principles:
is the capture all the motion events to translate your view with the finger
use a Gesture Detector to detect the onFling(), check if the fling is in the right direction, and if yes, apply whatever action you need.
Unfortunately I've never implemented such, so I can't show you any code. But hopefully that points you to the right direction.
I want to add a sliding panel view using cocos2d for android. Any suggestions.
The way i've achieved this in one of my previous android market apps for paintball field designing is to have a separate CCLayer class added as a child to the main scene, and have the main scene responding to the CCTouchesBegan. if the location of the touch is within the co-ords of the visible panel, then call a 'touched' method inside it passing the touch co-ords, so that it can deal with it's own content.
On another panel at the bottom I had a button, which showed or hid the side panel, so it didn't 'slide' or support being 'flung' across the screen, but rather was shown or hidden.
Sliding it or flinging it on/off the screen could be written relatively simply i believe, using a combination of CCTouchesMoved and CCTouchesEnded to track the slide/fling and perform translation on the layer co-ords.
There's nothing to have prevented me implementing a slide in/out using some simple animation, but I had no requirement for it in the app, and hence didn't implement it.
Hope this is at least of some use,sorry i can't provide some worked examples right now, busy with work.
