本文介绍了一个Activity页面中使用RadioGroup来切换多个Fragment的实现方法。通过onCreate方法初始化界面，设置默认显示的Fragment，并监听RadioGroup的选择变化，动态显示和隐藏不同的Fragment。

Activity页面

  protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        frag = findViewById(R.id.frag);
        group = (RadioGroup)findViewById(R.id.group);
        group.check(group.getChildAt(0).getId());
	
        group.check(group.getChildAt(0).getId());
        fragment011 = new Fragment01();
        fragment022 = new Fragment02();
        fragment033 = new Fragment03();
        manager = getSupportFragmentManager();
        transaction = manager.beginTransaction();
        transaction.add(R.id.frag,fragment011);
        transaction.add(R.id.frag,fragment022);
        transaction.add(R.id.frag,fragment033);

        transaction.show(fragment011).commit();

        group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                switch (checkedId){
                    case R.id.radio0:
                        manager = getSupportFragmentManager();
                        transaction = manager.beginTransaction();
                        transaction.show(fragment011).hide(fragment022).hide(fragment033).commit();
                        break;
                    case R.id.radio1:
                        manager = getSupportFragmentManager();
                        transaction = manager.beginTransaction();
                        transaction.show(fragment022).hide(fragment011).hide(fragment033).commit();
                        break;
                    case R.id.radio2:
                        manager = getSupportFragmentManager();
                        transaction = manager.beginTransaction();
                        transaction.show(fragment033).hide(fragment022).hide(fragment011).commit();
                        break;
                }
            }
        });
    }
