Solution 1:

Use this method to get co-ordinates on canvas touch point

    final int index = e.getActionIndex();
    final float[] coords = new float[] { e.getX(index), e.getY(index) };
    Matrix matrix = new Matrix();
    view.getImageMatrix().invert(matrix);
    matrix.postTranslate(view.getScrollX(), view.getScrollY());
    matrix.mapPoints(coords);
    return coords;
