在还没给大家介绍单选按钮(RadioGroup)的使用，先给大家展示下效果图吧：
xml文件
java文件
public class
MainActivity extends Activity {
private TextView txt=null;
private RadioGroup sex=null;
private RadioButton male=null;
private RadioButton female=null;
@Override
protected void
onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.txt=(TextView)
super.findViewById(R.id.txt);
this.sex=(RadioGroup)
super.findViewById(R.id.sex);
this.male=(RadioButton)
super.findViewById(R.id.male);
this.female=(RadioButton)
super.findViewById(R.id.female);
this.sex.setonCheckedChangeListener(new
onCheckedChangeListenerImp());
} private class
onCheckedChangeListenerImp implements
OnCheckedChangeListener{
public void
onCheckedChanged(RadioGroup group, int checkedId)
{ String temp=null;
if(MainActivity.this.male.getId()==checkedId){
temp="男";
} else if(MainActivity.this.female.getId()==checkedId){
temp="女";
} MainActivity.this.txt.setText("您的性别是"+temp);
} }
以上所述是小编给大家介绍的Android程序开发中单选按钮(RadioGroup)的使用详解，希望对大家有所帮助！
