How to extend ImageView via java?

Question

Java

It is necessary to change the parameter for the image by the checkbox:
android:layout_width="wrap_content"
to
android:layout_width="fill_content"
and back.

Answer 1

As far as I know, there is no parameter for width and height called fill_content.
I will think that this is a typo and you need fill_parent.
Then this line of code can solve your problem:

//сделать по ширине родителя:
imageView1.getLayoutParams().width = LayoutParams.FILL_PARENT;

or

//сделать по ширине контента
imageView1.getLayoutParams().width = LayoutParams.WRAP_CONTENT;

It is desirable to use MATCH_PARENT instead of FILL_PARENT.
