What is the correct way to specify dimensions in DIP from Java code?

Question

I found that it is possible to set dimensions of my interface elements in XML layouts using DIPs as in following fragment:

android:layout_width=\"10dip\"
         


        

Answer 1

I think the best way is not to define any dimensions in code, but use the values/dimens.xml file instead. You can always define your dimension in the desired unit like:

120dp

and then refer to this in your Activity like:

getResources().getDimensions(R.dimen.my_layout_height);

This would return pixels after doing the necessary conversions. And also of course you can refer to this in your other XMLs like:

android:layout_width="@dimen/my_layout_height"
