Solution 1:

If you want to do same effect (exactly same effect), you can watch how Android do it here: https://github.com/android/platform_frameworks_base/blob/3f453164ec884d26a556477027b430cb22a9b7e3/core/java/android/widget/ImageView.java

Interesting part of code about CENTER_CROP:

[...]
mDrawMatrix = mMatrix;

float scale;
float dx = 0, dy = 0;

if (dwidth * vheight > vwidth * dheight) {
    scale = (float) vheight / (float) dheight; 
    dx = (vwidth - dwidth * scale) * 0.5f;
} else {
    scale = (float) vwidth / (float) dwidth;
    dy = (vheight - dheight * scale) * 0.5f;
}

mDrawMatrix.setScale(scale, scale);
mDrawMatrix.postTranslate((int) (dx + 0.5f), (int) (dy + 0.5f));
