在XML中引用字符串资源的INTEGER值

Question

Is it possible to reference not the representated string, but the integer key of a resource in xml?

<string name="first_string">First! :-D</string>
<string name="second_string">Second :(</string>

<integer-array name="something">
    <item>@string/first_string</item>
    <item>@string/second_string</item>
</integer-array>

This for example does not work, because @string/first_string is resolved to First! :-D First! :-D , instead of it's resource key (for example 0x7f0c0010 ). Is there any way at all to access that?

Answer 1

In java, you have integer values in generated R.class of your project.

For instance:

int value = R.string.first_string;

In XML, it's not possible to get it.

Answer 2

One thing that has a similar effect as putting the keys in an xml array, is by accessing it in java with obtainTypedArray instead of getIntArray or getStringArray .

typedArray = getResources().obtainTypedArray(R.array.something);
int id = typedArray.getResourceId(0, -1); // 1st param: position, 2nd: default value

if (id == R.string.first_string);  // true
if (id == R.string.second_string); // false

Hope that helps someone! For me (op), this seems not to help at all, since I can't access the stored preferences in this way, which is why I needed it in XML directly if at all possible.
