public bool StartDragAndDrop (Android.Content.ClipData? data, Android.Views.View.DragShadowBuilder? shadowBuilder, Java.Lang.Object? myLocalState, int flags);[<Android.Runtime.Register("startDragAndDrop", "(Landroid/content/ClipData;Landroid/view/View$DragShadowBuilder;Ljava/lang/Object;I)Z", "", ApiSince=24)>]
member this.StartDragAndDrop : Android.Content.ClipData * Android.Views.View.DragShadowBuilder * Java.Lang.Object * int -> boolParameters
- data
- ClipData
A android.content.ClipData object pointing to the data to be
transferred by the drag and drop operation.
- shadowBuilder
- View.DragShadowBuilder
A android.view.View.DragShadowBuilder object for building the
drag shadow.
- myLocalState
- Object
An java.lang.Object containing local data about the drag and
drop operation. When dispatching drag events to views in the same activity this object
will be available through android.view.DragEvent#getLocalState(). Views in other
activities will not have access to this data (android.view.DragEvent#getLocalState()
will return null).
<p>
myLocalState is a lightweight mechanism for the sending information from the dragged View
to the target Views. For example, it can contain flags that differentiate between a
a copy operation and a move operation.
</p>
- flags
- Int32
Flags that control the drag and drop operation. This can be set to 0 for no
flags, or any combination of the following:
<ul>
<li>#DRAG_FLAG_GLOBAL</li>
<li>#DRAG_FLAG_GLOBAL_PERSISTABLE_URI_PERMISSION</li>
<li>#DRAG_FLAG_GLOBAL_PREFIX_URI_PERMISSION</li>
<li>#DRAG_FLAG_GLOBAL_URI_READ</li>
<li>#DRAG_FLAG_GLOBAL_URI_WRITE</li>
<li>#DRAG_FLAG_OPAQUE</li>
</ul>
Returns
true if the method completes successfully, or
false if it fails anywhere. Returning false means the system was unable to
do a drag because of another ongoing operation or some other reasons.
