vertical 垂直排布

private RadioGroup rg ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
rg=(RadioGroup) findViewById(R.id. radioGroup1);
//实现RadioGroup的监听事件
rg.setOnCheckedChangeListener( new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
switch (checkedId) {
case R.id.radio :
System. out.println();
break;
case R.id.radio0 :
System. out.println();
break;
case R.id.radio1 :
System. out.println();
break;
default:
break;
}
}
});
}
