Get drawable image by its name

Question

I have a model and it has a specific country flag:

public int getCountryFlag() {
    return countryFlag;
}

public void setCountryFlag(int countryFlag) {
    this.countryFlag = countryFlag;
}

I am getting Data from an API. The API has a value country code and this could be like: "country":"de","created_at":"2018-08-08 09:17:43","updated_at":"2018-08-08 09:17:43"

I have the flags named as the country code:

de
se
us
....

How can I get the exact resourceID of the image to relate it to the model? I am using RecyclerView.

I tried something like:

int resID = getResources().getIdentifier(object.getString("country"), "drawable",  getPackageName());
model.setCountryFlag(R.drawable.sy);

Though that didn't work!

so are you saying that your drawable resource has the same name as that returned by the api? and your question is how to use that to access the drawable file? — Jacob Celestine, Aug 08 '18 at 10:05

If you're sure about the format of the api string then do the following:

String country = api.trim().split(",")[0].split(":")[1].replaceAll("\"", "");

or

String country = api.trim().substring(11, 13);

and then:

int resID = getResources().getIdentifier(country, "drawable",  getPackageName());
model.setCountryFlag(resID);

I am sure about the format of the API and I get the value of 0 always. So it's an exception error – Mike Aug 08 '18 at 10:38
@Mike So if you use `String country = api.substring(11, 13);` do you get the 2 letters for the country? – Aug 08 '18 at 10:41
Oh damn! This is working actually. I had forgotten to rename the file. I simply didn't have it correct in the folder. Thanks man :)) – Mike Aug 08 '18 at 10:44

You can get flag by Resource Id name

int drawableResourceId = this.getResources().getIdentifier("de", "drawable", this.getPackageName());

you can also check How to get a resource id with a known resource name?
