How to use custom designed numbers in your android widget

Wed, 04/07/2010 - 06:44 | by jozsi

SDK Version:

If you don't want to download external fonts into your application, this article will be useful to you. You can draw your own numbers for example in gimp from 0 to 9. Copy thoose numbers in to your project folder's res/drawable subfolder. Each number is a new png (for example: one.png, two.png...). Then don't forget to refresh this directory in eclipse.

In my last project I wrote an easy method, what I used to draw single numbers on a widget.

        /**
         * 
         * @param context
         *            - you need a context to draw the number
         * @param numberInt
         *            - the number, what you want to draw (0-9)
         * @param where
         *            - viewId
         * @param remoteView
         *            - RemoteViews type object, at instantiate you need to select a
         *            xml (for example: 
         *            RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widgetmain);
         *             )
         */
        private void intToImage(Context context, int numberInt, int where,
                        RemoteViews remoteView) {
                if (numberInt < 0 || numberInt > 9) {
                        Log.d("Tutorial", "Invalid number" + numberInt);
                } else {
 
                        int whereArray[] = { R.id.third, R.id.second, R.id.first }; // viewId
                        int images[] = { R.drawable.zero, R.drawable.one, R.drawable.two,
                                        R.drawable.three, R.drawable.four, R.drawable.five,
                                        R.drawable.six, R.drawable.seven, R.drawable.eight,
                                        R.drawable.nine }; // srcId
                        remoteView
                                        .setImageViewResource(whereArray[where], images[numberInt]);
                }
        }
 
}

Later you can use that like this:

                [...]
                int daysleft = (int) days;
 
                intToImage(context, (int) Math.floor(daysleft / 100), 0, remoteViews);
                daysleft = daysleft - (int) Math.floor(daysleft / 100) * 100;
                intToImage(context, (int) Math.floor(daysleft / 10), 1, remoteViews);
                daysleft = daysleft - (int) Math.floor(daysleft / 10) * 10;
                intToImage(context, daysleft, 2, remoteViews);
                [...]

That's it. Not a big thing, but I hope you found this article helpful.
