Android pinch zoom large image, memory efficient without losing detail

由 时间秒杀一切 提交于 2019-12-03 06:07:12
My app has to display a number of high resolution images (about 1900*2200 px), support pinch zoom. To avoid Out of memory error I plan to decode image to show full screen by using options.inSampleSize = scale (scale was calculated as Power of 2 as Document) (My view i used is TouchImageView extends of ImageView ) So i can quickly load image and swipe smoothly between screens(images). However, when i pinch zoom, my app loses detail because of scaled image. If i load full image, i can't load quickly or smoothly swipe, drag after pinch zoom. Then i try to only load full image when user begin

Elevation not working for ImageView

由 江枫思渺然 提交于 2019-12-03 05:28:59
Elevation for ImageView is not working. I declared ImageView in XML like this: <ImageView android:id="@+id/image" android:layout_width="100dp" android:layout_height="50dp" android:elevation="10dp" android:src="@drawable/youtube" /> What else should I do for elevation to work properly for ImageView? The elevation shadow is derived from the background drawable of a View. If your ImageView has no background, you'll see no shadow. If you want to change that behavior, you need to build your own ViewOutlineProvider and call View.setOutlineProvider() to set it (and this is not trivial). Works in all
