Hi Mark, Thanks for your reply. I saw the behaviour you are talking about. If I am not wrong, you are talking about the ability to drag the application icons on the home screen to different locations. I am also able to achieve that, but, unfortunately, that is not what I want. The feature that you are talking about only involves changing the position of a View, while my requirement is to find out the View over which the movable View is dropped. Please note that on the basis of which target view, it is dropped at, I need to do a particular task. So effectively, this problem is reduced to finding the View from the coordinates to which it is dropped or may be some better solution. Do You have any idea for how to go for this...

this.setLayoutParams (p);

I hope this helps as a pointer. Note that after you placed the object
to a new position, you have to remember the new coordinates (instead
of (10,10) where you started originally).
ACTION_DOWN is called when you click the mouse button, ACTION_MOVE is
called while you click and drag, and ACTION_UP is called when you
release the mouse button. Replace mouse by finger on the actual
device :-)
I hope this is what you meant.

Fwiw, changing layout parameters is a really inefficient way to do animations on the screen. I would strongly suggest looking at the launcher code and doing something inspired by that. -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support.

[android-developers] Re: DRAG AND DROP
I don't know what your final code looks like that you use, but you can change the visibility of the original item you are dragging temporarily using setVisibility(View.INVISIBLE) or View.GONE depending on how your layout is organized, so that only one item is visible while dragging. You could post your code here if you need further help.

Hi Peli
here i attach my code, to be added , i have ressolved the issue of double
image by getting rawX() value of the event , and setting my absolute layout
according to that.
but here i get a unique problem, whenever i click the button and try to drag
it, the mouse tip comes to a certain pixels above from the topleft corner of
the button,like a offset distance,if you run the code on the emulator u wil
find this problem.
can anyone help to solve this?

[android-developers] Re: DRAG AND DROP
what you have to do is, remember the coordinates that you get with the
ACTION_DOWN event.
Remember the distance (difference) between those coordinates and the
original coordinates of your image (call that offsetX and offsetY),
and subsequently in ACTION_MOVE always add those offset values.

[android-developers] Re: DRAG AND DROP
Introduce new member variables of your class:
int mOffsetX;
int mOffsetY;
Then below you do something like:
if ( action == MotionEvent.ACTION_DOWN ) {
System.out.println(X=+mCurX+ y=+mCurY);
this.setText(x: + mCurX + ,y: + mCurY );
mOffsetX = mCurX - 10; // 10 was the initial coordinate
mOffsetY = mCurY - 10;
} else if ( action == MotionEvent.ACTION_MOVE ) {
System.out.println(X=+mCurX+ y=+mCurY);
this.setText(x: + mCurX + ,y: + mCurY );
AbsoluteLayout.LayoutParams p = new
AbsoluteLayout.LayoutParams
(AbsoluteLayout.LayoutParams.WRAP_CONTENT,
AbsoluteLayout.LayoutParams.WRAP_CONTENT,this.getScrollX()+
mCurX + mOffsetX,
this.getScrollY()+mCurY + mOffsetY); Here you add the
offset values.
this.setLayoutParams (p);
}
I hope this helps as a pointer. Note that after you placed the object
to a new position, you have to remember the new coordinates (instead
of (10,10) where you started originally).
ACTION_DOWN is called when you click the mouse button, ACTION_MOVE is
called while you click and drag, and ACTION_UP is called when you
release the mouse button. Replace mouse by finger on the actual
device :-)
I hope this is what you meant.

You can also look at the source code of the Home (Launcher) application, in particular the class called DragLayer.

The basic idea is that you continuously put your image to a new position according to the coordinates that you obtain through ACTION_MOVE to give the illusion of dragging. In ACTION_UP you check whether the finger position is close to the target. in ACTION_DOWN you can remember the initial finger coordinates so that you can grab your icon everywhere correctly. Basically you have to code everything by yourself, but it should not be very difficult.

[android-developers] Re: DRAG AND DROP
hi all i have mentioned about a code link which can be used as an e.g. of the Drag_N_Drop feature, but there will be small change. the onMotionEvent(MotionEvent event) has to be replaced by onTouchEvent(MotionEvent event). though it starts the Drag_n_drop but it not smooth as u expect. rather here i am getting a abnormal behavior,i.e, i am getting double image of the button, that i drag and drop,Can anyone run the code sample and solve the issue...? regards Kaushik On Fri, Jan 9, 2009 at 2:39 AM, Peli peli0...@googlemail.com wrote: which can be found here: http://android.git.kernel.org/?p=platform/packages/apps/Launcher.git;a=blob;f=src/com/android/launcher/DragLayer.java with the related classes being here: http://android.git.kernel.org/?p=platform/packages/apps/Launcher.git;a=tree;f=src/com/android/launcher but this is the luxury version, including scaling of the image, scroll zones, and vibration :-) Peli On Jan 8, 8:16 pm, Romain Guy romain...@google.com wrote: You can also look at the source code of the Home (Launcher) application, in particular the class called DragLayer.
