[Résolu] Répondre à un appui long sur une ImageView

private static final String IMAGEVIEW_TAG = "icon bitmap"

// Creates a new ImageView
ImageView imageView = new ImageView(this);

// Sets the bitmap for the ImageView from an icon bit map (defined elsewhere)
imageView.setImageBitmap(mIconBitmap);

// Sets the tag
imageView.setTag(IMAGEVIEW_TAG);

    ...

// Sets a long click listener for the ImageView using an anonymous listener object that
// implements the OnLongClickListener interface
imageView.setOnLongClickListener(new View.OnLongClickListener() {

    // Create a new ClipData.
    // This is done in two steps to provide clarity. The convenience method
    // ClipData.newPlainText() can create a plain text ClipData in one step.

    // Create a new ClipData.Item from the ImageView object's tag
    ClipData.Item item = new ClipData.Item(v.getTag());

    // Create a new ClipData using the tag as a label, the plain text MIME type, and
    // the already-created item. This will create a new ClipDescription object within the
    // ClipData, and set its MIME type entry to "text/plain"
    ClipData dragData = new ClipData(v.getTag(),ClipData.MIMETYPE_TEXT_PLAIN,item);

    // Instantiates the drag shadow builder.
    View.DragShadowBuilder myShadow = new MyDragShadowBuilder(imageView);

    // Starts the drag

            v.startDrag(dragData,  // the data to be dragged
                        myShadow,  // the drag shadow builder
                        null,      // no need to use local data
