Summary

Constants

int SOURCE_ANY

A special input source constant that is used when filtering input devices to match devices that provide any type of input source.

int SOURCE_CLASS_BUTTON

The input source has buttons or keys.

int SOURCE_CLASS_JOYSTICK

The input source is a joystick.

int SOURCE_CLASS_MASK

A mask for input source classes.

int SOURCE_CLASS_NONE

The input source has no class.

int SOURCE_CLASS_POINTER

The input source is a joystick.

int SOURCE_KEYBOARD

The input source is a keyboard.

int SOURCE_MOUSE

The input source is a mouse pointing device.

int SOURCE_ROTARY_ENCODER

The input source is a rotating encoder device whose motions should be interpreted as akin to those of a scroll wheel.

int SOURCE_STYLUS

The input source is a stylus pointing device.

int SOURCE_TOUCHPAD

The input source is a touch pad or digitizer tablet that is not associated with a display (unlike SOURCE_TOUCHSCREEN).

int SOURCE_TOUCHSCREEN

Constants

SOURCE_ANY

public static final int SOURCE_ANY

A special input source constant that is used when filtering input devices to match devices that provide any type of input source.

Constant Value: -256 (0xffffff00)

SOURCE_CLASS_BUTTON

public static final int SOURCE_CLASS_BUTTON

The input source has buttons or keys. Examples: SOURCE_KEYBOARD, SOURCE_DPAD. A KeyEvent should be interpreted as a button or key press.

Constant Value: 1 (0x00000001)

SOURCE_CLASS_JOYSTICK

public static final int SOURCE_CLASS_JOYSTICK

The input source is a joystick. A MotionEvent should be interpreted as absolute joystick movements. Use InputDevice.getMotionRange(int) to query the range of positions.

Constant Value: 16 (0x00000010)

SOURCE_CLASS_MASK

public static final int SOURCE_CLASS_MASK

A mask for input source classes. Each distinct input source constant has one or more input source class bits set to specify the desired interpretation for its input events.

Constant Value: 255 (0x000000ff)

SOURCE_CLASS_NONE

public static final int SOURCE_CLASS_NONE

The input source has no class. It is up to the application to determine how to handle the device based on the device type.

Constant Value: 0 (0x00000000)

SOURCE_CLASS_POINTER

public static final int SOURCE_CLASS_POINTER

The input source is a pointing device associated with a display. Examples: SOURCE_TOUCHSCREEN, SOURCE_MOUSE. A MotionEvent should be interpreted as absolute coordinates in display units according to the View hierarchy. Pointer down/up indicated when the finger touches the display or when the selection button is pressed/released. Use InputDevice.getMotionRange(int) to query the range of the pointing device. Some devices permit touches outside the display area so the effective range may be somewhat smaller or larger than the actual display size.

Constant Value: 2 (0x00000002)

SOURCE_CLASS_POSITION

public static final int SOURCE_CLASS_POSITION

The input source is an absolute positioning device not associated with a display (unlike SOURCE_CLASS_POINTER). A MotionEvent should be interpreted as absolute coordinates in device-specific surface units. Use InputDevice.getMotionRange(int) to query the range of positions.

Constant Value: 8 (0x00000008)

SOURCE_CLASS_TRACKBALL

public static final int SOURCE_CLASS_TRACKBALL

The input source is a trackball navigation device. Examples: SOURCE_TRACKBALL. A MotionEvent should be interpreted as relative movements in device-specific units used for navigation purposes. Pointer down/up indicates when the selection button is pressed/released. Use InputDevice.getMotionRange(int) to query the range of motion.

Constant Value: 4 (0x00000004)

SOURCE_DPAD

public static final int SOURCE_DPAD

The input source is a DPad.
