android - how to get the image edge x/y position inside imageview

Question

If i have an ImageView that fills the screen.
The ImageView background is set to green color.
I place a bitmap in the ImageView, keeping bitmap proportions.

Answer 1

Here is a method I wanted to share, it will return the offset of the bitmap inside an imageView using getImageMatrix

public static int[] getBitmapOffset(ImageView img,  Boolean includeLayout) {
        int[] offset = new int[2];
        float[] values = new float[9];

        Matrix m = img.getImageMatrix();
        m.getValues(values);

        offset[0] = (int) values[Matrix.MTRANS_Y];
        offset[1] = (int) values[Matrix.MTRANS_X];

        if (includeLayout) {
            ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) img.getLayoutParams();
            int paddingTop = (int) (img.getPaddingTop() );
            int paddingLeft = (int) (img.getPaddingLeft() );

            offset[0] += paddingTop + lp.topMargin;
            offset[1] += paddingLeft + lp.leftMargin;
        }
        return offset;
    }
