The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). ` public final class InputDeviceCompat ` ` extends Object `` ` |---|-------------------------------------------| | java.lang.Object || | ↳ | android.support.v4.view.InputDeviceCompat |

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 added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_CLASS_BUTTON ``` The input source has buttons or keys. Examples:[SOURCE_KEYBOARD](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_KEYBOARD),[SOURCE_DPAD](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_DPAD). A[KeyEvent](https://developer.android.com/reference/android/view/KeyEvent.html)should be interpreted as a button or key press.
Constant Value: 1 (0x00000001) ### SOURCE_CLASS_JOYSTICK added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_CLASS_JOYSTICK ``` The input source is a joystick. A[MotionEvent](https://developer.android.com/reference/android/view/MotionEvent.html)should be interpreted as absolute joystick movements. Use[getMotionRange(int)](https://developer.android.com/reference/android/view/InputDevice.html#getMotionRange(int))to query the range of positions.
Constant Value: 16 (0x00000010) ### SOURCE_CLASS_MASK added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` 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 added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` 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 added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_CLASS_POINTER ``` The input source is a pointing device associated with a display.

Pointer down/up indicated when the finger touches the display or when the selection button is pressed/released. Use[getMotionRange(int)](https://developer.android.com/reference/android/view/InputDevice.html#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.

(It may also be a[SOURCE_JOYSTICK](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_JOYSTICK)).
**See also:** - [SOURCE_CLASS_BUTTON](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_BUTTON) Constant Value: 1025 (0x00000401) ### SOURCE_HDMI added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_HDMI ``` 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.
Constant Value: 33554433 (0x02000001) ### SOURCE_JOYSTICK added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_JOYSTICK ``` The input source is a joystick. (It may also be a[SOURCE_GAMEPAD](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_GAMEPAD)).
**See also:** - [SOURCE_CLASS_JOYSTICK](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_JOYSTICK) Constant Value: 16777232 (0x01000010) ### SOURCE_KEYBOARD added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_KEYBOARD ``` The input source is a keyboard. This source indicates pretty much anything that has buttons. Use[getKeyboardType()](https://developer.android.com/reference/android/view/InputDevice.html#getKeyboardType())to determine whether the keyboard has alphabetic keys and can be used to enter text.
**See also:** - [SOURCE_CLASS_BUTTON](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_BUTTON) Constant Value: 257 (0x00000101) ### SOURCE_MOUSE added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_MOUSE ``` The input source is a mouse pointing device. This code is also used for other mouse-like pointing devices such as trackpads and trackpoints.
**See also:** - [SOURCE_CLASS_POINTER](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_POINTER) Constant Value: 8194 (0x00002002) ### SOURCE_ROTARY_ENCODER added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` 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.
**See also:** - [SOURCE_CLASS_NONE](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_NONE) Constant Value: 4194304 (0x00400000) ### SOURCE_STYLUS added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_STYLUS ``` 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)](https://developer.android.com/reference/android/view/MotionEvent.html#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](https://developer.android.com/reference/android/view/MotionEvent.html#TOOL_TYPE_FINGER)and another pointer with tool type[TOOL_TYPE_STYLUS](https://developer.android.com/reference/android/view/MotionEvent.html#TOOL_TYPE_STYLUS). So it is important to examine the tool type of each pointer, regardless of the source reported by[getSource()](https://developer.android.com/reference/android/view/MotionEvent.html#getSource()).

**See also:** - [SOURCE_CLASS_POINTER](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_POINTER) Constant Value: 16386 (0x00004002) ### SOURCE_TOUCHPAD added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_TOUCHPAD ``` The input source is a touch pad or digitizer tablet that is not associated with a display (unlike[SOURCE_TOUCHSCREEN](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_TOUCHSCREEN)).
**See also:** - [SOURCE_CLASS_POSITION](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_POSITION) Constant Value: 1048584 (0x00100008) ### SOURCE_TOUCHSCREEN added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_TOUCHSCREEN ``` The input source is a touch screen pointing device.
**See also:** - [SOURCE_CLASS_POINTER](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_POINTER) Constant Value: 4098 (0x00001002) ### SOURCE_TOUCH_NAVIGATION added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_TOUCH_NAVIGATION ``` 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.
**See also:** - [SOURCE_CLASS_NONE](https://developer.android.com/reference/android/support/v4/view/InputDeviceCompat#SOURCE_CLASS_NONE) Constant Value: 2097152 (0x00200000) ### SOURCE_TRACKBALL added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int SOURCE_TRACKBALL ``` The input source is a trackball.
