getAction() returns a pointer id and an event (i.e., up, down, move) information.
getActionMasked() returns just an event (i.e., up, down, move) information. Other info is masked out.
For example:
getAction() returns 0x0105.
getActionMasked() will return 0x0005, which is 0x0105 && ACTION_MASK.
- The value of ACTION_MASK is 0xFF. It masks the following actions.
- ACTION_DOWN 0, UP 1, MOVE 2
- ACTION_POINTER_DOWN 5, UP 6
- The value of ACTION_POINTER_ID_MASK is 0xFF00. It masked the pointer ID from following deprecated constants.
- ACTION_POINTER_1_DOWN 0x0005
- ACTION_POINTER_2_DOWN 0x0105
- ACTION_POINTER_3_DOWN 0x0205
