I want to use some predefined dimensions from my dimens.xml file in my programmatic layout.
So for instance, in my dimens.xml file I have:
<dimen name="margin1">40dip</dimen>
<dimen name="margin2">40dip</dimen>
And then in my programmatic textview I have:
RelativeLayout.LayoutParams lpMargin = new RelativeLayout.LayoutParams( R.dimen.margin1, R.dimen.margin2);
Applying the layout parameter to my textview results in an enormous view.
I already found the problem. If I print out:
Log.e("Metrics", "margin width = " + String.valueOf(R.dimen.margin1));
...it gives an enormous value: margin width = 2131034112. The thing that's messing it up is the units, "dip".
So my question is: what's the correct way to specify dimensions without units for calling programmatically? If that's not possible, can I alter R.dimen.margin1 so I can use it as a programmatic layout parameter?
EDIT: It wasn't the units messing it up -- it's returning the internal ID! (As ianhanniballake says below, I needed to call with getResources().getDimension(R.dimen.margin1)).
