Android touchlistener implementation drag and drop instance code

If the touch monitor is set for a control, the control will move with the user's drag. If the drag distance is greater than the set critical value, there will be a callback ondragcomplete when the finger is released. The user can delete the control from the parent layout in this method, or perform other operations. If the user's drag distance is less than the critical value, the control will return to its original position when the user releases his finger. The ondragbound callback is triggered. If the user directly releases his finger without dragging after touching the control, the onclick callback will be triggered, so the user does not need to set onclick listening for the control.

The source code is as follows:

If you inherit this class and override three callback methods, you can get a callback at the right time.
