Your response will be very useful for me and another one
Hello I'm developing an example of this in github https://github.com/mtparet/Drag-And-Drop-Android
It could help you.
All contribution are welcome
Take a look at this sample that Drag and drop inside a List View..
Drag and drop sample...Click on You can find the project here. and Download the Zip file..
The ACTION_UP
and ACTION_DOWN
constants returned by MotionEvent.getAction()
refer to the state of finger taps (for example, finger is placed down on screen, finger is lifted up from screen), not to movement direction. You will need to also use the MOVE
action in combination with ACTION_UP
and ACTION_DOWN
to accomplish what you're trying to do.
For example, in your onTouch
method, when you receive MOTION_DOWN
(user has pressed down on the ListView item), identify which item the user tapped on. You can then track the MOVE
action to give visual cues, such as to draw a floating "ghost" version of the item that follows their finger. Finally, when you receive MOTION_UP
(user lifted their finger after dragging), identify which column their finger was over and do whatever you need to do to move the data over to the other list.
You can use the x and y coordinates provided with each MotionEvent
to determine things like which item the user tapped on, which list they moved their finger over, etc.
