Android ImageView gets scaled image on screen

Question

In my code, I load an image from the source code into my ImageView. ScaleType of this image is FIT_CENTER. My original image is much larger than the screen. Can I get the width and height or scale ratio of the image on the screen? I can do this manually, how, based on the orientation of the image, calculate the ratio of the area in which the ImageView is located and the ratio of the image itself. After the relationship, I can guess what sizes are set (e.g. width or height) and so on ...

Is there any other easy way to do this?

Answer 1

, adjustViewBound true scaleType XY.

android:adjustViewBounds="true"
android:scaleType="fitXY"

Answer 2

ImageView

getDrawable(). getIntrinsicHeight()

.

Answer 3

hi set fitXY scale type like this. android:scaleType="fitXY"

Answer 4

There is another way to “auto-scale” your image. You should set the loaded bitmap as the background of the ImageView control instead of setting it as the source. Hope this helps.
