回答1:

I am not sure if I understood correctly. It must be either of the two, that you want, I guess.

In your image view set the attribute

android:scaleType="fitXY"

to fit the ImageView completely.

You can choose

android:scaleType="centerCrop"

to crop Center.

i know it's late but maybe it would be helpful for someone coming on this question page by using android:scaleType="centerCrop" image is centered but it is cropped from all sides so it would be better to use this property instead that is fitCenter and with this use another property too to maintain the aspect ratio

android:adjustViewBounds="true"            
android:scaleType="fitCenter"

Are you aware of the cropping options on ImageView?

You will just apply these as an attribute in your XML:

like:

android:scaleType="centerCrop"

in java: imageView.setScaleType(ScaleType.FIT_XY);
