实现点击Button跳转Fragment效果

第一步：XML设置按钮

第二部：设置几个Fragment

第三部：代码实现

//获取Fragment的管理类对象
supportFragmentManager = getSupportFragmentManager();
//开启一个事物
begin = supportFragmentManager.beginTransaction();
//为这个事物添加一个Fragment
begin.add(R.id.framelayout,new YIFragment());
//开启这个事物
begin.commit();

//点击切换Fragment

@Override
public void onClick(View view) {
    switch (view.getId()){
        case R.id.zhonghe:
            //replace 替换
            supportFragmentManager.beginTransaction().replace(R.id.framelayout,new YIFragment()).commit();
            break;
        case R.id.dongtan:
            supportFragmentManager.beginTransaction().replace(R.id.framelayout,new ERFragment()).commit();
            break;
        case R.id.faxian:
            supportFragmentManager.beginTransaction().replace(R.id.framelayout,new SANFragment()).commit();
            break;
        case R.id.wode:
            supportFragmentManager.beginTransaction().replace(R.id.framelayout,new SIFragment()).commit();
            break;
    }
}
