Complications

“any feature in a timepiece beyond the simple display

of hours and minutes” (Wikipedia)

#dfua

Complication types

-Short text-Long text-Range of values-Icon (small picture)-Image (big picture)

Complications coding

#dfua

Each position need to be identified

private static final int LEFT_DIAL_COMPLICATION = 0;

private static final int RIGHT_DIAL_COMPLICATION = 1;

public static final int[] COMPLICATION_IDS = {LEFT_DIAL_COMPLICATION,

RIGHT_DIAL_COMPLICATION};

Complication ID

#dfua

Each position must be mapped with array of supported types

// Left and right dial supported types.

public static final int[][] COMPLICATION_SUPPORTED_TYPES = {

{ComplicationData.TYPE_SHORT_TEXT},

{ComplicationData.TYPE_SHORT_TEXT}

};

Complication supported types

#dfua

Data Providers and system trigger .onComplicationDataUpdate() sometimes

/* Called when there is updated data for a complication id. */

@Override

public void onComplicationDataUpdate(

int complicationId, ComplicationData complicationData) {

Log.d(TAG, "onComplicationDataUpdate() id: " + complicationId);

mActiveComplicationDataSparseArray.put(complicationId, complicationData);

invalidate();

}

ComplicationData receiving

#dfua

.onDraw() is the moment of drawing. ComplicationData where stored earlier

@Override

public void onDraw(Canvas canvas, Rect bounds) {

ComplicationData complicationData;

for (int i = 0; i < COMPLICATION_IDS.length; i++) {

complicationData = mActiveComplicationDataSparseArray

.get(COMPLICATION_IDS[i]);

// ...

Complications rendering

#dfua

Complication may be deactivated or contain wrong data type

if ((complicationData != null)

&& (complicationData.isActive(currentTimeMillis))

&& (complicationData.getType() ==

ComplicationData.TYPE_SHORT_TEXT)) {

ComplicationText mainText = complicationData.getShortText();

CharSequence complicationMessage =

mainText.getText(getApplicationContext(),

currentTimeMillis);


#dfua

Actual drawing is trivial

canvas.drawText(

complicationMessage,

0,

complicationMessage.length(),

complicationsX,

mComplicationsY,

mComplicationPaint);

#dfua
