Quantization string: Android authoritative programming 13.7 challenge exercise-optimize string resource display

Notice that there is only one crime record, and the subtitle showing the total number of records is displayed: 1 crimes. Please correct this careless grammatical error.
In the implementation of the idea, you can prepare different string resources in the code to use, but this will give the application localization manufacturing trouble. It is good practice to use complex string resources (also known as quantization strings).
First, the complex string resource is defined in the Strings.xml file.

<plurals name= "subtitle_plural" ><item quantity= "one" >%1$s crime</item><item quantity= "other" >%1$s crimes</item></plurals>

Then, use the Getquantitystring method to correctly handle the single complex problem.

1 int crimesize = crimelab.getcrimes (). Size (); 2 String subtitle = getresources ()3 . getquantitystring (R.plurals.subtitle_plural, Crimesize, crimesize);
