Android Image Viewer, Full Screen Zoom and CenterCrop

How can I get an image that fills the screen but maintains its aspect ratio and fits in the center?

I currently have large images, larger than my phone screen resolution, but I suspect they will be inboxes on higher resolution devices

What combination scaleType

will perform the trick?

You can just use adjustViewBounds

value to keep the aspect ratio of the image



<ImageView
        android:id="@+id/metallicaImage"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:adjustViewBounds="true"
        android:src="@drawable/metallica" />

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scaleType="fitCenter" />


This is the basic setting.

I ran into this before, the problem is that when the image needs to be scaled (screen width is larger than the image), Android will not scale the image beyond its given size. However, scaling works just fine.

I ended up creating the AspectRatioImageView

one mentioned below works well. Be sure to read the comments about getIntrinsicWidth()

returning 0 and getDrawable()

returning zero and put some security checks in them.

How do I stretch three images across the screen while maintaining the aspect ratio?
