In-call UI: New visual design treatment for lo-res contact photos
Add a special effect for "lo-res" contact photos (i.e. the 96x96
thumbnails we typically get from contacts sync.)
Rather than simply scaling up the image (which looks terrible since the
onscreen photo is now so much larger than the source image) we instead
show a large blurred version of the image, overlaid with a smaller "inset"
of the original unblurred image.
Implementation details:
- InCallContactPhoto: this new class behaves just like an ImageView,
*except* if you call setImageDrawable() and pass in a BitmapDrawable
that's 96x96 or smaller. In that case, the "special effect" kicks in:
We generate a blurred version of the input bitmap, display that in the
InCallContactPhoto widget itself, and also show a separate ImageView
with a smaller "inset" of the original image.
The CallCard now uses InCallContactPhotos instead of ImageViews for both
the foregound and "on hold" contact photos. (We never show the inset
for the "on hold" call, though.)
- BitmapUtils: this is a new utility class that contains the actual
gaussianBlur() implementation (borrowed from the Music2 app.)
- Performance seems fine so far; the blur adds something like 100msec to
the setImageDrawable() call, but that happens asynchronously anyway
(since we already have to wait for the contact photo lookup) so it has
no effect on the initial startup time of the InCallScreen.
(But if this *does* turn out to be a problem there's definitely room for
improvement, like by optimizing the current BitmapUtils code, or even by
pushing the gaussianBlur() implementation down into RenderScript.)
TESTED:
- Lo-res photos from contacts sync:
==> blur + inset effect is shown
- Hi-res photos from the device's camera:
==> original photo is shown with no special effect
- Incoming and outgoing calls
- Two calls in use / swap / merge
- Turn the screen on and off during a call
- Exit and return to the in-call screen during a call
