Android :: Drag And Drop From Source View To Target View
Sep 17, 2009
I have a problem statement, and here it is: My requirement is: There are a number of images shown on the screen. I want to allow the user to drag and drop any of the images to anyother image. Based on which image is dragged and on which is it dropped, I need to do something specific. So, I need to find a way so that I can get my source view and my target view.To understand this in a better way, consider a practical scenario. In the File Explorer of Windows, we can drag and drop items from the left pane showing the directory tree to any of the folders shown in the right pane.If anyone of you ever faced a similar scenario, please let me know because I could not find a direct support to such a thing (Drag and Drop) in the platform, so may be I need to find an innovative solution to it.

My understanding is that when you have a view that's too small to easily touch, you're supposed to use a TouchDelegate to increase the clickable region for that view. However, searching for usage examples on Google turn up multiple people asking the question, but few answers. Does anyone know the proper way to set up a touch delegate for a view to, say, increase its clickable region by 4 pixels in every direction?

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............

I noticed that AbsoluteLayout is deprecated in the latest SDK. AbsoluteLayout is an important piece to implementing drag and drop. If it disappears in a later release, what will be the solution to implement drag and drop?

I want to know how to manual sort with ListView by using drag and drop? for example, the user can drag an item from position 2 to position 1. Someone said there is a play list activity that can support it in music application. But I cannot find it in my SDK 1.0. Who can provide some suggestion? If there is a demo, it is more better.

I'm just wondering if I'm able to create a View from an external XML source. As I was reading, you must place the XML layout inside the res/layout and when you compile it, you can load the layout by typing setContentView(R.layouts.my_layout). What if I have this XML layout online (on a website) and I want to create the layout on runtime? Is there any way to do this? Or I have to parse the XML and create the layout (hard-coded)?

In browsers when I type view-source: before any address it gives me the page source. But i am not able to do it in android. It gives me "web page not available" . Can any one please tell me why it is giving that and any other way for me to view the page source in android?
One more doubt is what exactly is "@hide", even if I commented it( /** @hide */) it is having some meaning( it is not visible in another classes ). When I deleted it its working fine, it is visible. what is the reason?

I am working on something that needed custom drag-and-drop functionality, so I have been subclassing View, doing a bunch of math in response to touch events, and then rendering everything manually through code on the canvas in onDraw. Now, the more functionality I add, the more the code is growing out of control and I find myself writing a ton more code than I would expect to write in a high level environment like Android.
Is this how it's done, or am I missing something? If I'm not doing anything fancy in the UI, the framework handles the majority of my interactions. Built-in controls handle the touches and drags, and my code is pretty much limited to business logic and data. Is there a way to leverage the power of some of the UI controls and things like animations while also doing some of it manually in the onDraw canvas? Is there an accepted standard of when to use one or the other (if indeed the two approaches can be mixed)?

I have a table-top style game board consisting of 10x10 squares. Each square is a PNG image. On top of these squares I want to place tiles which can be drag and dropped on top of the squares.
What would be my best approach concerning Views?
Is it possible to have two layers where layer one is a grid of ImageView's which represents the board. Would it then be possible to let the tile be an ImageView also which could be "stacked" on top of the ImageView's which represents the board?

I am working on a MapView app in Android. I have three markers that I want to be able to use the Google Map API getlocation-function on, later on. In order to try it out I would like to move the marker with a drag and drop-function, and then check the location.
Anyone who has gotten a drag and drop to work on an android marker, or know a way to start figuring it out?

I want to dynamically pull in a layout from an external source. As discussed in this thread from September 2009 -
http://groups.google.com/group/android-developers/browse_thread/threa.
I am wondering if the situation has changed since this discussion or if it is likely to change. I understand the need to use pre-compiled xml layouts so if there is an option to dynamically pull in a layout that is already compiled that would be fine. Basically I want a setup where I can change a view layout without an app update. The elements within the view would be fairly static (e.g. there will be 2 buttons call foo and bar that fire fooOnClick and barOnClick). The only work around I can think of is a custom scripting language that allows the definition of views that are created from code. Ideally this would parse the same xml as a standard layout. Obviously this would involve a lot of code and probably be fairly slow.
Button btnFoo = new Button(); btnFoo.setText("foo"); dynamicLayout.addView(btnFoo);
If this is the only option at least the EdsMagicLayoutInflater class would be reusable across projects.

If you look at the Android documentation about how to implement a List View and populate it you will notice that they only teach you how to do it in Java extending ListActivity instead of the normal Activity, but how would the same code (layout and populate the list) using XML layout files and extending Activity?
I'm asking this because I want to implement a RelativeLayout and add more elements to the screen where the ListView is with more flexibility than using .inflate() and addHeaderView()/addFooterView().

I am looking for an app that allows me to use drag and drop to reorder tasks and also synchronizes with Microsoft Exchange.
Many of the great task apps (Any.Do, Wunderlist) have drag and drop capability but do not sync with Exchange. Those that do sync with exchange don't have drag and drop functionality.
I have tried Touchdown, Tasks For Microsoft Exchange, Tasks and Notes for MS Exchange, TaskSync for Exchange, Any.Do, Wunderlist, and Remember the Milk.

I connect the usb to charge, but I cant drag and drop files like I did with my Instinct through Windows. Currently, I have to take the mini sd card out of the phone and put that into my computer to connect that way to add music, etc. Anyone know anything about how to drag and drop directly when connected with the usb?
