How to get a id of string array from Strings.xml without direct id reference

Question

I have a number of arrays stored in Strings.xml file in my android project. I want to populate a list from these Arrays based upon a button click. depends upon which button clicked, i need to populate different lists. So the code is very messy by adding a nested if else structure. Is there any way to get the String Array from the Strings.xml where i can call it using a single common method for all. I am keeping the same name for button tag and array name. please help....`

current code is

if(submit_button.getTag().toString.equalsIgnoreCase("vacation"){
return getResources().getStringArray(R.array.vacation);
}
else if(submit_button.getTag().toString.equalsIgnoreCase("summer"){
return getResources().getStringArray(R.array.summer);
}
else if(submit_button.getTag().toString.equalsIgnoreCase("monsoon"){
return getResources().getStringArray(R.array.monsoon);
}
else if(submit_button.getTag().toString.equalsIgnoreCase("automn"){
return getResources().getStringArray(R.array.automn);
}
else if(submit_button.getTag().toString.equalsIgnoreCase("rainy"){
return getResources().getStringArray(R.array.rainy);
}
else if(submit_button.getTag().toString.equalsIgnoreCase("humid"){
return getResources().getStringArray(R.array.humid);
}
else if(submit_button.getTag().toString.equalsIgnoreCase("sunny"){
return getResources().getStringArray(R.array.sunny);
}
else{
return null;
}

<string-array name="myarray">
    <item>value1</item>
    <item>value2</item>
    <item>value3</item>
    <item>value4</item>
</string-array>

And in your java code,

String[] MyArray = getResources().getStringArray(R.array.myarray);

I hope this is what you need, If not please let me know.

use this method to get the array id from array name..

private int getArrayId(String arranameString) {

    int id = this.getResources().getIdentifier(arranameString, "array", this.getPackageName());

    return id;

}

This will return the id of your string array

there is no need to parsing it into Long.

You use this code;

For string:

public static int getImageResourceIDFromName(String tag,
            Context context) {

        int identifier = context.getResources().getIdentifier (tag,"string",context.getPackageName());
        return identifier;  
    }

For Array:

public static int getImageResourceIDFromName(String tag,
            Context context) {

        int identifier = context.getResources().getIdentifier (tag,"array",context.getPackageName());
        return identifier;  
    }

You need to pass name of identifier then it will return ids of that particular resource it will help you create lots if else statement,
