Android get value of the selected radio button

Question

I have a RadioGroup rg1 and I want to get the value of the selected radio button.

I know that I can get the id of the selected radio button by using:

if(rg1.getCheckedRadioButtonId()!=-1)
int id= rg1.getCheckedRadioButtonId()

that gives me the id , but I want the value of that button.

You need to get the radio button at that index, then get the value of the text of that button. Try this code below.

if(rg1.getCheckedRadioButtonId()!=-1){
    int id= rg1.getCheckedRadioButtonId();
    View radioButton = rg1.findViewById(id);
    int radioId = radioGroup.indexOfChild(radioButton);
    RadioButton btn = (RadioButton) rg1.getChildAt(radioId);
    String selection = (String) btn.getText();
}

Is the id returned from getCheckedRadioButton only the id within the RadioGroup? Why couldn't you get the id of the button and then use a more general findViewById to get the RadioButton instad of adding extra steps of indexOfChild and getChildAt – Rarw May 28 '13 at 18:52

What is radioGroup at int radioId = radioGroup.indexOfChild(radioButton); – Mitesh Shah May 06 '14 at 13:24
radioGroup is the object of RadioGroup; That group contains all the radio button. It is parent for those radio button – Simon Chius Apr 21 '15 at 10:17
so rg1 and radioGroup is the same object in that case, right? – Jack Lynx Aug 23 '16 at 15:28
Or you can get the radio button with their ID's and get its text if its checked using `isChecked` method. Like this `RadioButton radio_male = ((RadioButton) findViewById(R.id.rbtn_male)); String gend = radio_male.isChecked() ? radio_male.getText().toString() : radio_female.getText().toString();` – vikas devde Dec 26 '17 at 15:13
Couldn't you simply have done - `(RadioButton) rg1.findViewById(id).getText();` ? – Aman Grover Apr 19 '20 at 18:36

try this:

RadioGroup rg = (RadioGroup)findViewById(R.id.youradio);
String radiovalue = ((RadioButton)findViewById(rg.getCheckedRadioButtonId())).getText().toString();

rb1=(RadioButton)findViewById(rg1.getCheckedRadioButtonId());

Now you can use rb1.getText() to get the text on the Radiobutton that is checked

I think you should try this

RadioGroup rg=(RadioGroup)findViewById(R.id.youradio);
String radiovalue=(RadioButton)this.findViewById(rg.getCheckedRadioButtonId())).getText().toString();

Get the radio button text only when a radio button is checked in a radio group by this Kotlin code -

radioGroup.setOnCheckedChangeListener { rg, i ->
    val selectedId = radioGroup.checkedRadioButtonId
    val radioButton = findViewById<RadioButton>(selectedId)
    myTextView.text = radioButton.text
}
