onTouchEvent

public void onTouchEvent(AbilityForm form,

从类复制的说明: ViewListener

A callback method registered with the AbilityForm supplier for you to implement callbacks upon touch events.

Generally, this method is triggered in the following scenario:

1. The developer of the supplier uses AbilityForm#registerViewListener(int, ViewListener) to register a callback method upon touch events.
2. When a touch event is dispatched to a component on the client, the event is sent to the supplier through the AbilityForm framework, and the AbilityForm framework triggers the registered callback method ViewListener#onTouchEvent(AbilityForm, ViewsStatus).

form - Indicates the AbilityForm object provided by the supplier.

viewsStatus - Indicates the status of components for which a listener has been set on the client.
