public class MainActivity extends Activity {
private RadioGroup rg = null;
private Button bt = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
rg = (RadioGroup) findViewById(R.id.rg_sex);
bt = (Button) findViewById(R.id.bt_sex);
bt.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
int count = rg.getChildCount();   //获取单选按钮组内的所有单选按钮
String msg = null;
for (int i = 0; i < count; i++) {
RadioButton rb = (RadioButton) rg.getChildAt(i);
if(rb.isChecked()){
msg = rb.getText().toString();
break;   //找到选中按钮，终止循环
}
}
Toast.makeText(MainActivity.this, msg, 1).show();
