I have string array that looks like this:
<string-array name="USA">
<item name="NY">001</item>
<item name="LA">002</item>
<item name="WA">003</item>
</string-array>
I can get those numbers by:
Resources res = getResources();
int arryid = res.getIdentifier("USA", "array", getPackageName());
String[] numbers = res.getStringArray(arryid);
But how can I also get the names (NY,LA,WA)? Note that I have a lot of counties... Maybe use different approach?
In the documentation there is no name attribute for an <item>.
So I don't think there will be any way to get those keys.
However, if you want to get name of string or string-array, you can get it programmatically but not for the <item>.
As "001" is just the index, why not simply use that?
<string-array name="USA">
<item>NY</item>
<item>LA</item>
</string-array>
Then just use index + 1 for the position:
String[] usaStates = getResources().getStringArray(R.array.USA);
int index = 0;
String firstStateName = usaStates[index];
int firstStatePosition = (index + 1);
That aside, you can use two arrays and merge them into a HashMap:
<string-array name="USA">
<item>NY</item>
<item>LA</item>
</string-array>
<string-array name="USA_pos">
<item>001</item>
<item>002</item>
</string-array>
String[] usaStates = getResources().getStringArray(R.array.USA);
String[] usaStatePositions = getResources().getStringArray(R.array.USA_pos);
Map <String, String> map = new HashMap<>(usaStates.length);
for (int i = 0; i < usaStates.length; i++) {
map.put(usaStates[i], usaStatePositions[i]);
}
String[] numbers = getResources().getStringArray(R.array.USA);
to get data from array use.
numbers[id]
add array like this.
<string-array name="USA">
<item>NY</item>
<item>LA</item>
<item>WA</item>
</string-array>
