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.

Answer 1

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 – Euell

What is radioGroup at int radioId = radioGroup.indexOfChild(radioButton); – Wapiti

radioGroup is the object of RadioGroup; That group contains all the radio button. It is parent for those radio button – Armanda

so rg1 and radioGroup is the same object in that case, right? – Frisk

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(); – Inclinable

Couldn't you simply have done - (RadioButton) rg1.findViewById(id).getText(); ? – Wappes

try this:

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

Answer 5

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

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

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

Answer 9

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
}
