import android.widget.Toast;
public class MainActivity extends Activity {
RadioGroup rg;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
rg = (RadioGroup)findViewById(R.id.radioGroup1);
Button showGender = (Button)findViewById(R.id.button1);
showGender.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
int id = rg.getCheckedRadioButtonId();
RadioButton rb = (RadioButton)findViewById(id);
String gender = rb.getText().toString();
Toast.makeText(getApplicationContext(), gender+"Selected", Toast.LENGTH_LONG).show();
}
});
}
}
In this code at least u select one Radio button otherwise it show force close error.
