Android12 Framework blocks mouse left/right button sliding events

For Android devices that support a mouse, both the left and right buttons can drag space or respond to system gestures. The current requirement is to block the sliding event of the right mouse button and only respond to the sliding of the left mouse button.

To correct this problem you need to know the following constants.

AMOTION_EVENT_BUTTON_PRIMARY left click

AMOTION_EVENT_BUTTON_SECONDARY right click

AMOTION_EVENT_BUTTON_TERTIARY Auxiliary button

The specific changes are as follows:

Block the right-click move event.
