Programmatically center TextView text

Question

I beg some leniency here  I m just starting with the Android SDK tutorials and I m attempting something out of interest that s not in the tutorial itself  but I would hope would be easy   I am trying to center a TextView item via code horizontally and vertically  I can do it in XML just fine   I ve seen several examples of how to do this when the parent is a table or some other object  but I hope this would be easier for me to grasp   p s  Feel free to correct my terminology    Here is the example code from the tutorial   my working model   package com example myfirstapp   import android os Bundle  import android app Activity  import android content Intent  import android view ViewGroup LayoutParams  import android widget TextView    public class DisplayMessageActivity extends Activity        Override     public void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           Intent intent   getIntent            String message   intent getStringExtra MainActivity EXTRA MESSAGE            TextView textView   new TextView this           textView setTextSize 40           textView setText message           textView setGravity View TEXT ALIGNMENT GRAVITY            setContentView textView             I ve managed to locate the setGravity method  and I ve tried to dabble in the setLayoutParams for it  but I m not sure what the scope is for it as I can t locate what I should be importing to get the WRAP CONTENT constant to resolve  From what I understood  centering and content wrapping gravity are two separate things  I d like an example of how to do both in this case and maybe how where I would have found the answer in the API documentation
