本文介绍了一个基于Android的应用中实现不同功能模块（Fragment）间切换的方法。通过RadioGroup监听选择变化来动态替换显示的Fragment，实现了主菜单界面的功能切换。

package com.quanten.globalcard.moudle.main;

import android.app.Activity;


import android.os.Bundle;
import android.support.v4.app.FragmentTransaction;
import android.widget.RadioGroup;

import com.quanten.globalcard.R;
import com.quanten.globalcard.framework.app.BaseActivity;

/**

public class MenuActivity extends BaseActivity
{
    private RadioGroup radioGroup;
    private FragmentTransaction fragmentTransaction;

    private HomeFragment homeFragment;
    private InternetFragment internetFragment;
    private MallFragment mallFragment;
    private MyFragment myFragment;

    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_menu);

        radioGroup = (RadioGroup) findViewById(R.id.menu_rg_navigate_bar);
        radioGroup.setOnCheckedChangeListener(getListener());


        homeFragment = new HomeFragment();
        internetFragment = new InternetFragment();
        mallFragment = new MallFragment();
        myFragment = new MyFragment();

        getSupportFragmentManager().beginTransaction().add(R.id.munu_fl_container, homeFragment).commit();

    }

    @Override
    protected void initLogics() {

    }

    private RadioGroup.OnCheckedChangeListener getListener()
    {
        return new RadioGroup.OnCheckedChangeListener()
        {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId)
            {
                if (radioGroup == group)
                {
                    if (checkedId == R.id.munu_rb_home)
                    {
                      getSupportFragmentManager().beginTransaction().replace(R.id.munu_fl_container, homeFragment).commit();
                    }
                    else if (checkedId == R.id.munu_rb_internet)
                    {
                        getSupportFragmentManager().beginTransaction().replace(R.id.munu_fl_container, internetFragment).commit();
                    }
                    else if (checkedId == R.id.munu_rb_mall)
                    {
                        getSupportFragmentManager().beginTransaction().replace(R.id.munu_fl_container, mallFragment).commit();
                    }
                    else if (checkedId == R.id.munu_rb_my)
                    {
                        getSupportFragmentManager().beginTransaction().replace(R.id.munu_fl_container,myFragment ).commit();

                    }
                }
            }
        };
    }
