TestWearableButtonsProvider

public class TestWearableButtonsProvider implements 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);

Public constructors

TestWearableButtonsProvider

public TestWearableButtonsProvider(
    @NonNull Map<IntegerTestWearableButtonsProvider.TestWearableButtonLocation> buttons
)

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

Parameters
@NonNull Map<IntegerTestWearableButtonsProvider.TestWearableButtonLocation> buttons

The buttons returned by this provider.

Public methods

getAvailableButtonKeyCodes

@Override
public int[] getAvailableButtonKeyCodes(@NonNull Context context)

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
@NonNull Context context

The context of the current activity

Returns
int[]

An int array of available button keycodes, or null if no keycodes could be read.

getButtonInfo

@Override
public @NonNull Bundle getButtonInfo(@NonNull Context context, int keycode)

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
@NonNull Context context

The context of the current activity

int keycode

The keycode associated with the hardware button of interest

Returns
@NonNull Bundle

A Bundle containing the metadata for the given keycode
