I'm not sure I have any suggestions. I have not done anything with WindowsManager. Most of what I have done relies on there being a ViewGroup in which all the events can be handled. I do not know how WindowManager fits in with that. However, the newer drag-drop framework introduced in API 11 might be able to do it. I have one example that is built with that: Drag-Drop for a GridView (V4).

Hello blahti,

this work is just great! I´m actually trying to have some achievements using drag and drop but I can´t find the clue. I found your job some hours ago and I started to play with it, actually what I would like to achieve in is using drag and drop with and overlay button (always on top of any app ) added through WindowsManager, I thought you might have some ideas about how I should approach this issue.

Thanks a lot.

The current version compiles with Android 2.3.3, but I think it will compile and run with Android 2.2. Just change set android:minSdkVersion=”8″ in AndroidManifest.xml. If you want to have more than one GridView active in the app, all you have to do is use the code in my GridView example. In onDragStart of DragLayer, find the code that goes through the GridView children and adds them as DropTargets. With a second GridView, you could do the same.

In my example, I moved an image from one place to another. That happens in onDrop of ImageCell. To impose more constraints on what can move, I think you could add more logic in onDrop.

I think you could add a swap feature easily. In onDrop of ImageCell, change the code to check the the cell number of what is in the DragSource. So then, at the point of drop, you know both the cell number of the drop target and the source. Be sure to cast DragSource, as in “ImageCell isource = (ImageCell) source;”. Then do what you need for your kind of swap.

Does it have Swap feature, when you drag and drop an image to a grid that alreday contains an image?

Hi Blahti.

Can you give a tutorial on how to implement drag and drop functionality on differing images making them target specific?

By this I mean, If you have say, 4 draggable images; image_drag_1, image_drag_2, image_drag_3, and image_drag_4 and 4 drop_target images; image_drop_1, image_drop_2, image_drop_3, and image_drop_4.

image_drag_1 should be matched to image_drop_1 and any attempt to drop image_drag_1 on any other drop image or location in the screen layout, makes image_drag_1 snap back to its original position.

I tired modifying your code to suit my purpose but it yielded no result. Thanks in advance!
