Question

I can’t seem to rotate properly an image on the entire screen. The problem is that when the image rotates, you can see the background in some areas. I want the image to fill the screen also when it rotates. Here is the layout. I’ve tried different scale types without success.

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <ImageView
        android:id="@+id/image"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scaleType="centerCrop" />
</LinearLayout>

And here is the code that I am using.

image = (ImageView) findViewById(R.id.image);
image.setBackgroundResource(R.drawable.back_big);
rot = AnimationUtils.loadAnimation(this, R.anim.rotation);
image.startAnimation(rot);

I start the animation in onResume. As I said, the image rotates but there are background areas when it does rotate. I’ve tried using images much bigger than the screen but still it doesn’t do what I want. I don’t care that outer regions of the image are not visible. I just want the rotation to fill the screen. I guess ImageView sets its width and height initially and then, when it rotates, it uses those dimensions. Is there a better way to do this?

After looking more at the problem, I don’t think it’s possible to achieve what I want. If it is possible, then it is too complicated and it’s not worth it.
