I have a problem:
I have implemented in my project the drag & drop with some icons simulating the drag & drop of android 2.2.
So, when you click for one second an icon, you can start to move your finger and insert your icon in any part of the screen. The basic behaviour of android 2.2 (API level 8) is that when you do a long click, there is a little Vibration and an Animation of the icon that you have touched and you can start to move.
I have implemented the vibration but i have no idea of what i can implement the little animation.
I have read about a scaleAnimation but I'm not sure.
Can anyone explain me the best way to implement this animation?
There are some tutorial or example?
Thanks in advance.

Here is the nice example of drag and drop with animation replacing view DraggableGridView
you can inflate your custom layout too and can handle all the events relating with the same.

Hello Guys I am trying to implement tab dragging in one of my project that is supposed to run on android 2.2 or higher which is similar to Google chromium Desktop browser in dragging and swapping .
I have thought the following way to implement it which are as follow and
using the given logic http://jqfaq.com/how-to-drag-and-drop-replace-the-position/ with Linear Layout as vertical orientation and adding and removing element with gesture and animation
using Custom ViewPager and Fragments to achieve the same
Extending FrameLayout and adding and removing tab dynamically and when user press and start dragging then shuffle all the tab .. but this way in need to destroy and create all the visible tab again to give the same effects , with this way might work but mine progress and activity work will has to be recreated
Using Activity Group as Drag and Drop with view start from api level 11
i hope you guys got my problem and come up with suggestion and if have some ready made sample and best way to it
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.
my android version is 2.2
I want to make ui like easyband (youtube video)
so, how to drag and drop imageView or button between other layout?
and I want know insert imageView or button array of items to use drag and drop
plz help me
Your answer would be Android drag and drop framework.
However, I guess you are just at the beginning to solve your problem, try to ask more specific questions (like I have tried this method and it's giving me this error) instead of looking for a whole answer
Try creating a GridView that allows you to drop views from one area to another. Here is Bill Lahti's code and examples of the similar Drag and Drop effect on lower API's.

I have a need to create a circular dial/rotary style component for use in an application. It's essentially a circular menu that allows users to select from the items that are ringed around it, and then they can click the button in the center to activate the selected item. However, I've never created a custom UIView of this type, and don't really know where to begin. Can anyone give me any pointers as to how I would draw the view and then rotate it as the user drags their finger? I obviously know how to intercept touch events, etc. but I'm not sure how to actually go about manipulating the UI appropriately. Any tips or pointers would be great!
I don't know if you've already found a solution to this, but here is a nice overview of how to get started:
http://shahabhameed.blogspot.com/2011/05/custom-views-in-android.html
For you, I think you can extend an existing View, that View being the SeekBar. You can take the standard SeekBar and draw it in a circle.
Finally, here is a source code that does the rotation with a volume knob. It is its own project though, so you have to do some work to use it in your own app.

Good Luck!
I have a neat library to do this. It is extremely stable and well maintained. https://bitbucket.org/warwick/hgdialrepo
Heres a youtube demo: https://youtu.be/h_7VxrZ2W-g
This library comes with a demo app with source code and the demo app actually uses a dial as a menu, So I think this should be the perfect solution for you.
I saw one iphone application if the button is visible and we press cancel button then that button should gone. in that case there is animation "the button diposes from left to right and finally got vanished". In android i am able to rotate any view or move it from left to right. But how can i get the effect that the button destroy animation and make a button visible in that type of animation.
Thanks

I'm not sure that I fully understand what you're trying to do, but it seems like you want to fade the button as well as translating it. If that's the case, then you can use alpha animations to change the opacity of the button. By gradually reducing the alpha to 0, the button will appear to fade away.
I have recently completed a series on animations on my blog. It is probably best to read the articles in order starting with the first, but the final article covers animating individual widgets.
To get a general idea of animations in android, check out this awesome page on quick actions. There is plenty of code and working animations with different options so you can get a full tutorial of how they work.
