class TestWearableButtonsProvider : WearableButtonsProvider

---

A WearableButtonsProvider suitable for use in tests.

This allows for explicitly specifying which buttons are available for testing, and their coordinates. It is intended to be used by passing in a map, mapping between the button keycode (typically in the set KEYCODE_STEM_PRIMARY, KEYCODE_STEM_1, KEYCODE_STEM_2, or KEYCODE_STEM_3) and the location of the button. Take the following example:

    Mapbuttons = new HashMap<>();
    buttons.put(KEYCODE_STEM_1, new TestWearableButtonLocation(100, 100);

    TestWearableButtonsProvider provider = new TestWearableButtonsProvider(buttons);

    WearableButtons.setWearableButtonsProvider(provider);

TestWearableButtonsProvider(
    buttons: (Mutable)Map<Int!, TestWearableButtonsProvider.TestWearableButtonLocation!>
)

Build a button provider, which will respond with the provided set of buttons.

Parameters
buttons: (Mutable)Map<Int!, TestWearableButtonsProvider.TestWearableButtonLocation!>	The buttons returned by this provider.

Public functions

getAvailableButtonKeyCodes

Added in 1.0.0

fun getAvailableButtonKeyCodes(context: Context): IntArray<Int>?

Get the keycodes of available hardware buttons on device. This function based on key's locations from system property. This count includes the primary stem key as well as any secondary stem keys available.

Parameters
context: Context	The context of the current activity

Returns
IntArray<Int>?	An int array of available button keycodes, or null if no keycodes could be read.

getButtonInfo

Added in 1.0.0

fun getButtonInfo(context: Context, keycode: Int): Bundle

Returns a bundle containing the metadata of a specific button. Currently, only location is supported. Use with X_KEY and Y_KEY. The key will not be present if the information is not available for the requested keycode.

The location returned is a Cartesian coordinate where the bottom left corner of the screen is the origin. The unit of measurement is in pixels. The coordinates do not take rotation into account and assume that the device is in the standard upright position.

Parameters
context: Context	The context of the current activity
keycode: Int	The keycode associated with the hardware button of interest

Returns
Bundle	A Bundle containing the metadata for the given keycode
