Android: How to refer to strings in a string definition [closed]

Question

Is there anyone knows how to refer to a defined string in a string definition, i.e.:

<string name="string_1">I am string 1</string>

and then,

<string name="string_2">I want to refer to @string/string_1</string>
<string name="string_3">@string/string_1 need to be referred here</string>

I've tried the sample codes, but it didn't work!

Answer 1

You could try using String.format():

<string name="string1">I am %1$s</string>
<string name="string2">String 1</string>

...
String string1 = String.format(resources.getString(R.string.string1, R.string.string2));

Answer 2

Yes you can do it at one condition as long as you reference the entire string

<string name="string_1">I am string 1</string>
<string name="string_2">I am string 2</string>

and then,

<string name="string_2">@string/string_1</string>
<string name="string_3">@string/string_2</string>

<string name="string_default">@string/string2</string>

but following is not supported

<string name="string_default">@string/string1 TEST</string>

You can also get your issue resolved by using String.format() (a good walk around)
