copied!<p>Using the drag-n-drop framework, instead that cycling the childs and setting the draglistener, I use as a grid item layout container, a DragableLinearLayout that extends the LinearLayout and implements the onDragEvent(DragEvent) method. </p> <p>So you can fill your grid with the adapter as usual and most of the drag and drop code is on the onDragEvent of DragableLinearLayout</p> <pre><code>public class DragableLinearLayout extends LinearLayout { public DragableLinearLayout(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public DragableLinearLayout(Context context, AttributeSet attrs) { super(context, attrs); } public DragableLinearLayout(Context context) { super(context); } @Override public boolean onDragEvent(DragEvent event) { //in wich grid item am I? GridView parent = (GridView) getParent(); Object item = parent.getAdapter().getItem( parent.getPositionForView(this)); //if you need the database id of your item...
