getBoolean won't accept string key with getSharedPreferences

This might be Android 101, but I'm getting used to the SDK now. Anyhow, I simply do not understand the error. I want to update some checkbox selections based on my shared preferences file and I'm using the following method:

private void updatePreferencesData() {

    SharedPreferences prefs = getSharedPreferences(PREFS_NAME, 0);

    Boolean textData = prefs.getBoolean(R.string.Chri, false);
    CheckBox cb1 = (CheckBox) findViewById(R.id.chkbxChristmas);
    cb1.setChecked(textData);

}

Android Studio doesn't like my use of R.string.Chri in Boolean textData = prefs.getBoolean(R.string.Chri, false);

It states: "getBoolean(java.lang.String, Boolean) in SharedPreferences cannot be applied to (int, Boolean)"

In my strings.xml I have the value:

<string name="Chri">Christmas</string>

When I simply change the line to 

 Boolean textData = prefs.getBoolean("Christmas", false);

It works fine

How is it that the strings in strings.xml is being handled differently?

Thank you!

R.string.Chri is an int. Instead use getResources().getString(R.string.Chri) to retrieve the string.

You should use:

 prefs.getBoolean(this.getResources().getString(R.string.Chri), false);

Correct. R.string.Chri is an int. To get a string, call getString(R.string.Chri) on some Context, such as your activity.
