Use android:textAllCaps:true it will work like a charm

 <TextView
    android:layout_width="0dip"
    android:layout_height="wrap_content"
    android:layout_weight="3"
    android:text="@string/app_name"
    android:textAllCaps="true"
    android:layout_gravity="center_vertical"
   android:textStyle="bold"
    android:typeface="sans" />

In Java code use 

   text.toUpperCase()

If you mean you want the TextView to capitalize everything that is put into it, then you can set the capitalize XML attribute on the TextView.

If you mean you only want capital letters to show up ex:

"Hi There!" --> "HT"

Then you need a little bit of Java code (from memory, untested):

private static String removeLowercase(String input)
{
   if(input == null)
     return null;

   String retVal = "";

   for(int i=0; i < input.length(); i++)
   {
        char c = input.charAt(i);

        if(Character.isUpperCase(c))
            retVal += c;
   }

   return retVal;
}

You can then set the text in the TextView:

myTV.setText(removeLowercase("SomeInput"));

This will convert the text to all uppercase

text.toUpperCase()
