Example 1
public boolean onLongClick(View v) {
    TextView thisTextView = (TextView) v;
    String dragContent = "Dragged Text: " + thisTextView.getText();

    //Set the drag content and type.
    ClipData.Item item = new ClipData.Item(dragContent);
    ClipData dragData = new ClipData(dragContent,
            new String[] {ClipDescription.MIMETYPE_TEXT_PLAIN}, item);

    //Set the visual look of the dragged object.
    //Can be extended and customized. Default is used here.
    View.DragShadowBuilder dragShadow = new View.DragShadowBuilder(v);

    // Starts the drag, note: global flag allows for cross-application drag.
    v.startDragAndDrop(dragData, dragShadow, null, DRAG_FLAG_GLOBAL);
