Reading string value from a text file into textView

I've been searching everywhere for a method that allows one to read a @string value from a text file. I'm not sure if I'm being entirely clear since I cannot seem to describe it in words so I'll use this snippet.

This is a <@string/square_root>

So when I read the file into a textview it includes the square root symbol with it. Is this possible? or if there is another method to do this.

The standard way to do this is to put your string in a resource file, typically res/values/strings.xml (Note below that 221A is the Unicode value of the square root symbol).

<string name="square_root">\u221A</string>

Then you can reference this string from either an XML layout file:

<TextView android:text="@string/square_root" ...>

Or from Java code:

Context context = this;  // in this example the current activity is the context
String title = context.getString(R.string.square_root);
TextEdit textEdit = ....
textEdit.setText(title);
