InputDeviceCompat

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

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

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

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.

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

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 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.

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 getMotionRange(int) to query the range of positions.

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 getMotionRange(int) to query the range of motion.

The input source is a DPad.

The input source is a game pad. (It may also be a SOURCE_JOYSTICK).

The input source is a device connected through HDMI-based bus. The key comes in through HDMI-CEC or MHL signal line, and is treated as if it were generated by a locally connected DPAD or keyboard.

The input source is a joystick. (It may also be a SOURCE_GAMEPAD).

The input source is a keyboard. This source indicates pretty much anything that has buttons. Use getKeyboardType() to determine whether the keyboard has alphabetic keys and can be used to enter text.

The input source is a mouse pointing device. This code is also used for other mouse-like pointing devices such as trackpads and trackpoints.

The input source is a stylus pointing device.

Note that this bit merely indicates that an input device is capable of obtaining input from a stylus. To determine whether a given touch event was produced by a stylus, examine the tool type returned by getToolType(int) for each individual pointer.

A single touch event may multiple pointers with different tool types, such as an event that has one pointer with tool type TOOL_TYPE_FINGER and another pointer with tool type TOOL_TYPE_STYLUS. So it is important to examine the tool type of each pointer, regardless of the source reported by getSource().

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

The input source is a touch screen pointing device.

The input source is a touch device whose motions should be interpreted as navigation events. For example, an upward swipe should be as an upward focus traversal in the same manner as pressing up on a D-Pad would be. Swipes to the left, right and down should be treated in a similar manner.

The input source is a trackball.

The input source is unknown.
