Android supports Plurals. Plurals are XML based resources which allow to handle different quantities. This way you can select the right text based on the quantity. In your XML file you specify values for the quantities “zero”, “one”, “two”, “many”, “few”, “many”, “other” and in your code you use the method getQuantityString() to get the correct value. You can also format strings. If now Strings are formated then you pass in the plural resources and the number. If Objects should be used for formating you pass them as additional parameters.
For example the following will define a plural. This file needs to be in the “res/values” directory and in this example it is called “plurals”.
<?xml version="1.0" encoding="utf-8"?>
<item quantity="zero">no Tutorial </item>
<item quantity="one">one Tutorial </item>
<item quantity="other">%d Tutorials</item>
The correct value can then be select via the following coding:
// number is defined somewhere before this
// number =….
// Get the Resources
Resources res = getResources();
// Get the
String quantityString = res.getQuantityString(R.plurals.tutorials,
// Do something with it…
From the Android development guide: Note that the selection is made based on grammatical necessity. A string for zero in English will be ignored even if the quantity is 0, because 0 isn’t grammatically different from 2, or any other number except 1 (“no tutorial”, “one tutorial”, “two tutorials”, and so on).
