setText method not working properly?

I am trying to execute the settext method on my textview but it doesn't seem to work. I learned that "%s" in the first argument of the string.format method should return the given string of the second argument but it somehow it doesn't work. 

SPCalories = Double.longBitsToDouble(sharedPreferences.getLong("Calories", Double.doubleToLongBits(0)));
d_c = SPCalories;
dc_text = Double.toString(d_c);
Calories_text.setText(R.string.Calories + String.format("%s", dc_text));

R.string.Calories:

<string name="Calories">Calories: </string>

Am I doing something wrong with SharedPreferences maybe?

You should do:

<string name="Calories">Calories: %s</string>

And: 

Calories_text.setText(String.format(getString(R.string.Calories), dc_text));

You omitted getString method:

Calories_text.setText(getString(R.string.Calories) + String.format("%s", dc_text));
