Answer 1

For anybody looking for this, I tried the above answer. Adding a margin to hide part of textureview to make it look square looks good in preview. But when saving the image, you should remove the hidden areas from the output image also.

An Easier solution is to show a full textureview and to overlay some other layouts on it to make it look square.You can easily crop the image from output.
