Get the string id of a button

Question

my button has a string id

<RadioButton 
android:id="@+id/Dirty" 
android:text="Very Dirty"

and I would like to use the name Dirty in my code but I cant use get Text since the display name of the radio button is different from what I need and get Id returns an integer.

Any suggestions on how to get the "Dirty" from my selected radio button?

Thanks.

Code (from comments)

RadioButton rb = (RadioButton) findViewById(selectedId); 
String sel = (String) rb.getText();

RadioButton rb = (RadioButton) findViewById(selectedId); String sel = (String) rb.getText(); — user3170, Dec 17 '13 at 08:37

Use getResourceEntryName method :

    RadioButton myButton = (RadioButton) findViewById(R.id.button1);
    String s = myButton.getResources().getResourceEntryName(R.id.button1);

Xml

the getText just returns the display name of the button and not the id name of the button. – user3170 Dec 17 '13 at 08:41

A workaround would be to add a tag with the same name as id to your radio button (in addition to id):

<RadioButton
    android:id="@+id/Dirty"
    android:tag="Dirty"
    android:text="Very Dirty"
    />

Then in your code you can get the tag as String:

RadioButton radioButton = (RadioButton)findViewById(R.id.Dirty);
String tag = (String) radioButton.getTag();

So the inconvenience would be to add tags to your radio buttons, which are the same as their id.

If you want to use a string to refer at your button, you should use Tag instead of Id.

I think you can find the answer here.

This one

getResources().getResourceName(int resid);

seems to be useful for you.

Try this:

int selectedRdBtnId = radioGroup.getCheckedRadioButtonId();
radioButton = (RadioButton) findViewById(selectedRdBtnId);
String rbText = radioButton.getText();

Edit:

For getting id, I would suggest implementing onCheckedChangeListener.

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(RadioGroup radioGroup, int radioButtonID) {
       //radioButtonID contains selected radio button's ID.

       case R.id.dirty:
           //do something
           break;
       case R.id.clean:
           //something else
           break;
       default:
           //default action
           break;
    }
});

Hope this helps.

The thing is that I know which radio button is selected and I can get the id but the id will always return an integer. I need the string name I gave to the button as an id. – user3170 Dec 17 '13 at 08:46
