How to pass string resource reference in string array in android

Question

I want to pass in string resource value in string array but it doesn't take value in array. it will take null value

Below is my code :

prepaid = getResources().getString(R.string.lbl_prepaid);
dth = getResources().getString(R.string.lbl_dth);

public String[] addedRTHomeList(){
        String[] homeList = {prepaid,dth,"PostPaid","Utility Services","Complaint Entry","Complaint Status","Recharge Status",chat,"Topup Request","Redeem Discount","Private Bus Booking","ST Bus Booking","Hotel Booking","Flight Booking","Money Transfer","Settings","Reports","DTH Activation"};
        return homeList;
    }


for(int i = 0; i < ba.addedRTHomeList().length ; i++)
        {
            md = new MenuDetail();
            md.setMenuName(ba.addedRTHomeList()[i]);
            md.setImageId(ba.RTDrwableListThemeRed()[i]);

            RTmenuListRed.add(md);

            RTMenuThemeRed.put(ba.RTMenuCode()[i],RTmenuListRed);
        }

In for loop when i access 1st value of addedRTHomeList array it take null value

You cannot to this homeList = {prepaid,dth} you can only combine using Array.combine — Murtaza Khursheed Hussain

Instead of this you can create <string-array> in your string.xml. like,

<string-array name="your_array_name">
    <item>Element 1</item>
    <item>Element 2</item>
    <item>Element 3</item>
    <item>Element 4</item>
    .
    .
    .

</string-array>

after this you can get in Java as,

String[] mTestArray = = getResources().getStringArray(R.array.your_array_name);

this may helps your problem.

Use AarryList instead of simple array becasue arraylist have easy dynamic implementation.

When you create array you have tell him its length.

public String[] addedRTHomeList(){
        String[] homeList = {prepaid,dth,"PostPaid","Utility Services","Complaint Entry","Complaint Status","Recharge Status",chat,"Topup Request","Redeem Discount","Private Bus Booking","ST Bus Booking","Hotel Booking","Flight Booking","Money Transfer","Settings","Reports","DTH Activation"};
        return homeList;
    }

Like Above homeList is size of 17 you cant add value in 18 index because 18 is not exist that why you are getting this error

Solution:

Use String ArrayList example usage

ArrayList<String> homeList = new ArrayList<String>();

homeList.add("PostPaid");
homeList.add("Complaint Status");
homeList.add("Recharge Status");

.
.
}

to get Value from ArrayList homeList.get(index) Simply.

now if you add value it will create new index and add it on last. Best Of Luck.

You are getting an exception because you are trying to initialize the variables as class variables. I moved the initialization inside addedRTHomeList() method and found no issues.

Try this code,

public String[] addedRTHomeList(){
    String prepaid = getResources().getString(R.string.lbl_prepaid);
    String dth = getResources().getString(R.string.lbl_dth);
    String chat = getResources().getString(R.string.lbl_chat);

    return new String[]{prepaid,dth,"PostPaid","Utility Services","Complaint Entry","Complaint Status","Recharge Status",chat,"Topup Request","Redeem Discount","Private Bus Booking","ST Bus Booking","Hotel Booking","Flight Booking","Money Transfer","Settings","Reports","DTH Activation"};
}

String[] items = ba.addedRTHomeList();
for(int i = 0; i < items.length ; i++){
    md = new MenuDetail();
    md.setMenuName(items[i]);
    md.setImageId(ba.RTDrwableListThemeRed()[i]);

    RTmenuListRed.add(md);

    RTMenuThemeRed.put(ba.RTMenuCode()[i],RTmenuListRed);
}
