java code

package com.mkyong.android;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Toast;

publicclassMyAndroidAppActivityextendsActivity {
    private RadioGroup radioSexGroup;
    private RadioButton radioSexButton;
    private Button btnDisplay;

    @OverridepublicvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    addListenerOnButton();

    }

    publicvoidaddListenerOnButton() {

        radioSexGroup = (RadioGroup) findViewById(R.id.radioSex);
        btnDisplay = (Button) findViewById(R.id.btnDisplay);

        btnDisplay.setOnClickListener(newOnClickListener() {

            @OverridepublicvoidonClick(View v) {

                    // get selected radio button from radioGroupintselectedId= radioSexGroup.getCheckedRadioButtonId();

                // find the radiobutton by returned id
                    radioSexButton = (RadioButton) findViewById(selectedId);

                Toast.makeText(MyAndroidAppActivity.this,
                    radioSexButton.getText(), Toast.LENGTH_SHORT).show();

            }

        });

    }
}

Solution 2:

try following code

radiogroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        publicvoidonCheckedChanged(RadioGroup group, int checkedId) {
            int id=group.getCheckedRadioButtonId();
            RadioButton rb=(RadioButton) findViewById(id);
                                     OR
            RadioButton rb=(RadioButton) findViewById(checkedId);

            String radioText=rb.getText().toString();

        }
    });

Solution 3:

try this...

    radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        publicvoidonCheckedChanged(RadioGroup group, int checkedId) {
            RadioButton radioButton = (RadioButton) group.findViewById(checkedId);
            String text = radioButton.getText().toString();
            updated_list.add(text);
        }
    });

Solution 4:

Kotlin code for retrieving text from a checked RadioButton in RadioGroup

    binding.genderRadiogroup.setOnCheckedChangeListener { _, _ ->
        var id: Int = binding.genderRadiogroup.checkedRadioButtonId
        var rb: RadioButton = binding.genderRadiogroup.findViewById(id)
        Toast.makeText(this,rb.text.toString(),Toast.LENGTH_SHORT).show()
    }

Solution 5:

Try this solution for retrieving the text:

radiogroup.setOnCheckedChangeListener(newRadioGroup.OnCheckedChangeListener() {

     voidonCheckedChanged(RadioGroup rg, int checkedId) {
          for (inti=0; i < rg.getChildCount(); i++) {
               RadioButtonbtn= (RadioButton) rg.getChildAt(i);
               if (btn.getId() == checkedId) {
                   Stringtext= btn.getText();
                   // do something with textreturn;
               }
          }
     }
});
