What I want to do is to get a specific text from strings.xml dynamically. I think it will involve to access an object variable dynamically.
There will be a function like:
public void getDynamicString(int level) {
text.setText(R.string.levelText_+level);
}
And in strings.xml there will be <string name="levelText_5">Text level 5</string>
I would rather not create a list with all the text resources. Can one do this in Java/Android.
Use the method getIdentifier(name, defType, defPackage) of the Resources class to get the id of a resource by name. Then you can do a normal getString(id) from the same class.
EDIT: a bit of Googling revealed this: this. You can find sample usage there.
Try: getResources().getString(R.id.stringId).
You should look at using getIdentifier(String, String, String) of the Resources class.
All you have to do is call
this.getString(R.string.levelText_5)
If your in an area of the program in which you have access to a Context or Application, such as a ListAdapter call:
context.getString(R.string.levelText_5)
or
application.getString(R.string.levelText_5)
if you have no access to the context or application then call:
getResources().getString(R.String.levelText_5);
To do it dynamically call:
String name = "levelText_"+level;
int id = getIdentifier(name, "string", "com.test.mypackage");
getResources().getString(id);
I had the same problem and I fixed it using this
okey , whenever you want to access a string from strings.xml dynamically and what i mean by that is to avoid using getResources().getString(R.id.stringId) ,you create a string in which you can manipulate dynamically however you want in our case uriq ("stupid variable name") and then you create resource object which is in my example level_res and initialize it then you use this method called getIdentifier() which accepts your dynamic string as a parameter ,now u simply pass your ressource to the method getstring(mysttring)
String uriq="level"+level_num;
level_res=getResources();
int mystring=getResources().getIdentifier(uriq,"string",getPackageName());
String level=level_res.getString(mystring);
