Using Unicode Character makes it very easy :

First create an array with your values(this will go to the number picker)

String mValues[] = { "100 " + "u33A1", "200 " + "u33A1" };

Now use this method to create number picker with custom values:

 private void setNubmerPicker(NumberPicker nubmerPicker,String [] numbers ){
    nubmerPicker.setMaxValue(numbers.length-1);
    nubmerPicker.setMinValue(0);
    nubmerPicker.setWrapSelectorWheel(true);
    nubmerPicker.setDisplayedValues(numbers);
}

And for the final step call this method:

  setNubmerPicker(yourNumberPicker,mValues);
