Hello! I have been testing your code and I'm not able to found why my image don't fit all the screen.

On both orientations i have on sides i.e: horizontal, i have white space west and east sides.. i want the images takes all the available spaces.
Hope you can help me! Great work!

First of all, thanks for the nice widget! There is a problem though when using the ScaleImageView with a ViewPager, weird things happen because the pager feeds unexpected values to the setFrame method. The problems is fixed in the code below.

protected boolean setFrame(int l, int t, int r, int b) {
    mWidth = r - l;
    mHeight = b - t;

    mMatrix.reset();

    /* When using this with a ViewPager, r can be for example -960 while l is -1440.
     * This is totally uncool, so we should make sure that the values are within
     * the screen size limits when used for other calculations. 
     */
    int r_norm = r - l;
    mScale = (float) r_norm / (float) mIntrinsicWidth;
    int paddingHeight = 0;
    int paddingWidth = 0;
    // scaling vertical
    if (mScale * mIntrinsicHeight > mHeight) {
        mScale = (float) mHeight / (float) mIntrinsicHeight;
        mMatrix.postScale(mScale, mScale);
        paddingWidth = (r_norm - mWidth) / 2;
        paddingHeight = 0;
        // scaling horizontal
    } else {
        mMatrix.postScale(mScale, mScale);
        paddingHeight = (b - mHeight) / 2;
        paddingWidth = 0;
    }
    mMatrix.postTranslate(paddingWidth, paddingHeight);

    setImageMatrix(mMatrix);
    mMinScale = mScale;
    zoomTo(mScale, mWidth / 2, mHeight / 2);
    cutting();
    return super.setFrame(l, t, r, b);
}

I wanted it to be of zoom scale 1 on load (so it looks exactly like ImageView) but on some images (depending on width to height ratio) it is zoomed slightly so can't see the whole image until manually zoom out by pinching the image.

I'm still debugging on where the calculation went wrong but haven't got an answer yet. If someone have please let me know thanks!

Hi, I am glad to have found out this project here. This is not an issue, it's more like I want to know the way to enable or disable ScaleImageview programmatically. Is it possible?

Hi,
I have checked your app it's working properly when image load from drawable or assign directly, but it's not working when I have used Picasso for a loading image.

ScaleImageView imgPhotoView = (ScaleImageView) findViewById(R.id.activity_photo_view_img);
Picasso.with(this).load(photoURL).fit().centerInside().into(imgPhotoView);

How can I check if my ImageView is zoomed or if it is shown as it is as default?
