Public Methods

public int getAxis ()

Since: API Level 12

Gets the axis id.

Returns
  • The axis id.

public float getFlat ()

Since: API Level 9

Gets the extent of the center flat position with respect to this axis.

For example, a flat value of 8 means that the center position is between -8 and +8. This value is mainly useful for calibrating self-centering devices.

Returns
  • The extent of the center flat position.

public float getFuzz ()

Since: API Level 9

Gets the error tolerance for input device measurements with respect to this axis.

For example, a value of 2 indicates that the measured value may be up to +/- 2 units away from the actual value due to noise and device sensitivity limitations.

Returns
  • The error tolerance.

public float getMax ()

Since: API Level 9

Gets the inclusive maximum value for the axis.

Returns
  • The inclusive maximum value.

public float getMin ()

Since: API Level 9

Gets the inclusive minimum value for the axis.

Returns
  • The inclusive minimum value.

public float getRange ()

Since: API Level 9

Gets the range of the axis (difference between maximum and minimum).

Returns
  • The range of values.

public int getSource ()

Since: API Level 12

Gets the source for which the axis is defined.

Returns
  • The source.
