Change Resource getString() programmatically

Question

Is there any way to change a R.string programmatically? Because it's throwing an error.

Basically I want to do this: String parkAdd = getString(R.string.stg_ParkAddress_+id);

Because I have hardcoded strings that are changed according ID.

I tried to do this but don't work:

String parkAdd = getString(R.string.stg_ParkAddress_1);
parkAdd = parkAdd.replace("1",id);
if (!parkAdd.equalsIgnoreCase("")){
    tvParkAddress.setText(parkAdd);
}

You cannot change the resource values programmaticaly. Basically you cannot change it at runtime — Aman Grover, Sep 01 '16 at 11:21
@AmanGrover but I need a solution to get this, will I need to make a switch? — FilipeOS, Sep 01 '16 at 11:22
But it is not possible to change any resource value at runtime. — Aman Grover, Sep 01 '16 at 11:26

@FilipeOS take a look at Gary's solution. I am not 100% sure it'll work, but it seems the only way if at all possible — Aman Grover, Sep 01 '16 at 11:32

The R.string.xxx is actually a constant and the value can't be appended to, the resource will never be found. You can search for R.java to see the values for your app:

public static final class string {
     public static final int about_open_source_heading=0x7f060013;
     public static final int about_open_source_list=0x7f060014;
}

If you have hard coded strings that depend on a specific value, maybe you can do something like this:

switch ( id ) {
   case 12345: 
      parkAddr = R.string.stg_ParkAddress_12345;
      break;
   case 12346: 
      parkAddr = R.string.stg_ParkAddress_12346;
      break;
}

Gary Bak, why are you accessing the `public static final class string`? – FilipeOS Sep 01 '16 at 11:37
@FilipeOS - that was just a sample of what the `R.java` file looks like. When you use the constants R.string.stg_ParkAddress_X you are referencing the final in that file/class. – Gary Bak Sep 01 '16 at 11:41

String resource can not be changed at runtime. You can save the string in SharedPreference which you can modify and save for further uses.

It is not possible to edit the string resources programmatically,Do another class and have your strings placed in this class and access during run time.

Simply concatenate it with id

String parkAdd = getString(R.string.stg_ParkAddress) + id;

No because it will fetch my string and not the stg_ParkAddress_X – FilipeOS Sep 01 '16 at 11:26
