re-setting a TextView height programmatically

Question

I want to reset a textView height after I have added it to the main window in the xml file.

inside a RelativeLayout,

Answer 1

the sample way for this if you want to use dimen

first, you should set size in dimen XML file.

50dp
50dp

and

text_l.getLayoutParams().height = 
     getResources().getDimensionPixelSize(R.dimen.text_height);

text_l.getLayoutParams().width = 
     getResources().getDimensionPixelSize(R.dimen.text_width);

Or

if you want to set just int (for example we wanna set 50dp height and 100dp width)

text_l.getLayoutParams().height = 50 * 3;
text_l.getLayoutParams().width= 100 * 3;
