查找片段在容器标签名称 [英] Find Fragment by tag name in Container

问题描述

我有个亲戚的布局，我将片段在相对布局。 像这样

I have a relative layout and i am adding fragment in that relative layout. Like this

     HomeFragment mHomeFragment = new HomeFragment();
    FragmentManager fragmentManager = getFragmentManager();
    FragmentTransaction fragmentTransaction =fragmentManager.beginTransaction();

    if(mHomeFragment!=null&& mHomeFragment.isAdded()){

        fragmentTransaction.show(mHomeFragment);

    }else {

        fragmentTransaction.add(R.id.order_container,mHomeFragment,"Search");


    }
    fragmentTransaction.commit();

我也有一个文本视图，我必须展示片段我加入了相对布局的名称。 就像情况下搜索。 如何获得片段在我相对布局假设与添加的名字              ID = R.id.order_container

I also have a text view where i have to display the name of fragment i added in the relative layout. Like search in case. How to get the name of fragment added in my relative layout suppose with id = R.id.order_container

推荐答案

您可以通过

Fragment fragment = getFragmentManager().findFragmentByTag("yourstringtag");

那么你可以检查你的片段instace HomeFragment

if (fragment instanceof HomeFragment) {
}
