Format method for string resource files in Android

Most of the time our sensibility to Google in the design of Android to adhere to a large number of MVC architecture, you can write public code, art and specific logic developers Independent. How do I implement a formatted string for the Android resource file Values/strings.xml?

<?xml version= "1.0" encoding= "Utf-8"?><resources>    <string name= "App_name" >stringdemo</ string>    <string name= "Hello" >hello robert</string></resources>

The above is a simple string resource file, it is not used to format, because it is relatively simple to directly describe the meaning, when we design a similar Delete xxx file? , we may need to dynamically get the name of XXX in Java, so it is easy to use formatting when defining resources, without the need for a bunch of strings to stitch or stringbuffer a silly way to append, see examples

<string name= "alert" >delete%1 $ s file</string>

Here%1 $ s represents this is a string type, if the integer type can be written as%1$d, like printf, such as formatted string function, of course, if it contains more than one need to format the content, the second can be written as%2$s or%2$d, then finally in Java how to call it? Look at the following example:

Example one: the integer type

<string name= "alert" >i am%1$d years old</string>

That's what defines it.
Of course, we eliminate the unexpected, such as the secret of a string type, note that%1$d is not%1 $ s, so the default standard merge becomes

int nage=23; String Sageformat = Getressources (). getString (R.string.alert); String sfinalage = String.Format (Sageformat, NAge);

When this is done, I am years old is formed.

You can also get direct access to

String sfinalage=getresources (). getString (R.string.alert,nage);

Here's what happens when you look at string strings.

Example Two: the String type

String sname= "Robert"; <pre name= "code" class= "java" >string scity= "Yantai";

Resource is defined as

<string name= "Alert2" >my name is%1 $ s, I am form%2$s</string>

In Java, you only need to

String Sinfoformat = Getresources (). getString (R.STRING.ALERT2); String Sfinalinfo=string.format (Sinfoformat, SName, scity);

The bank's final sfinalinfo shows that the content is

My name is Robert, I am form Yantai
