The replacement method in Android String.xml _android

This example describes the replacement method in the Android String.xml. Share to everyone for your reference, specific as follows:

In the development of Android, often meet a sentence, such as "I am 23 years old"; This 23 needs to be generated in the program, but there is a problem, this complete sentence is a textview, rather than three textview mosaic, It is written in a string.xml file, and can be implemented with string concatenation, but is especially troublesome;

Today encountered a good way, in the string.xml, not only can you set the text format line, and so on, you can also set the text format similar to the variable;

1, integral type , such as "I am 23 years old", this 23 is integral type. It can be written in String.xml, <string name= "old" > I%1$d this year </string>

In the program, use the

String Sageformat = Getresources (). getString (r.string.old);
String sfinalage = String.Format (Sageformat, 23);

Replace the%1$d with 23;

%1$d expression means the whole name= "old", the first integer substitution. If there are two integral types in a name that need to be replaced, the second one is:%2$d, and so on; Replace the string type shown in the program;

2, String type , such as "My name is Dick, I come from the capital of Beijing", where the "dick" and "capital of Beijing" need to be replaced.

It can be written in String.xml, <string name= "alert" > My name is%1 $ s, I am from%2$s</string>

In the program:

String SAGEFORMAT1 = Getresources (). getString (R.string.alert);
String SFinal1 = String.Format (SAGEFORMAT1, "Dick", "capital Beijing");

Here two strings need to be replaced, according to the order of the above program.

I hope this article will help you with the Android program.
