Find Fragment by tag name in Container

Question

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();

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

Answer 1

you can retrieve a Fragment by tag through

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

then you can check if your fragment is instace of HomeFragment

if (fragment instanceof HomeFragment) {
}

Answer 2

getSupportFragmentManager().findFragmentById(R.id.container).getClass().getName();

Answer 3

Fragment fragment = getFragmentManager().findFragmentById(R.id.order_container);
String tag = (String) fragment.getTag();

Answer 4

If you want to get the tag of a fragment you can use the getTag() method. This probably isn't going to be the nicest way to achieve what you are looking to do.

http://developer.android.com/reference/android/app/Fragment.html#getTag()

If you have several fragments and you will change them around, consider using an adapter.

Answer 5

You can use findFragmentById in FragmentManager

getFragmentManager().findFragmentById(R.id.order_container)

Answer 6

You want the name?? You can get your fragment using the ID and doing:

fragment.getClass().getName();

is it what you want? Or you can use:

fragment.getTag();

it's returns the tag name of the fragment, if specified.
