Remove all fragments from container

Is there a way to remove all fragments which are already added the specific view with its view id?

For example I want to remove all fragments which are added into R.id.fragmentcontainer view.

Here is much simplier way to clear all fragments from Fragment Container View

view.findViewById(R.id.fragmentcontainer).removeAllViews()

if you are using viewbinding then

binding.fragmentcontainer.removeAllViews()

This Kotlin extension does the job:

fun FragmentManager.removeAll(containerId: Int) {
    beginTransaction().apply {
        fragments.filter {
            it.id == containerId
        }.forEach {
            remove(it)
        }
    }.commit()
}

In case someone is looking for a code in Kotlin:

supportFragmentManager.apply {
        for (fragment in fragments) {
           beginTransaction().remove(fragment).commit()
        }
        popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE)
    }

As an addition to useful answers I have to say that if you have added few fragments to specific view container, for example:

getSupportFragmentManager()
    .beginTransaction()
    .add(containerViewId, fragmentA)
    .add(containerViewId, fragmentB)
    .commit();

and if you need just replace them by one, you can simply call replace without removing fragmentA and fragmentB

getSupportFragmentManager()
    .beginTransaction()
    .replace(containerViewId, fragment)
    .commit();

According to the docs replace removes all fragments before adding new:

Replace an existing fragment that was added to a container. This is essentially the same as calling remove(Fragment) for all currently added fragments that were added with the same containerViewId and then add(int, Fragment, String) with the same arguments given here.

Its very simple just loop through all the fragments and remove it

for (Fragment fragment : getSupportFragmentManager().getFragments()) {
    getSupportFragmentManager().beginTransaction().remove(fragment).commit();
}

But in case of Navigation Drawer be sure to check it, if you try to remove it you will get error.

for (Fragment fragment : getSupportFragmentManager().getFragments()) {
  if (fragment instanceof NavigationDrawerFragment) {
      continue;
  }
  else { 
      getSupportFragmentManager().beginTransaction().remove(fragment).commit();
  }
}

Last but very important be sure to check for null before doing any fragment transactions

for (Fragment fragment : getSupportFragmentManager().getFragments()) {
    if (fragment instanceof NavigationDrawerFragment) {
        continue;
    }
    else if (fragment != null) {
        getSupportFragmentManager().beginTransaction().remove(fragment).commit();
    }
}

More optimized version
There is no need in multiple call of commit so lets call it one time at the end

supportFragmentManager.fragments.let {
    if (it.isNotEmpty()) {
        supportFragmentManager.beginTransaction().apply {
            for (fragment in it) {
                remove(fragment)
            }
            commit()
        }
    }
}

Use this code

activity?.let {
it.supportFragmentManager.fragments.forEach { fragment ->
        it.supportFragmentManager.beginTransaction().remove(fragment).commit()
    }
}

Hope it helps.

Thank you.

Try this, hope it helps :D

try {
if(manager.getFragments()!=null){
    if(manager.getBackStackEntryCount()>0) {
        for (int i = 0; i < manager.getBackStackEntryCount(); i++)
            manager.popBackStack();

        manager.beginTransaction().remove(getSupportFragmentManager()
        .findFragmentById(R.id.main_content))
        .commit();
        }
    }
}catch (Exception e){
    e.printStackTrace();
}

It is indeed very simple.

private static void removeAllFragments(FragmentManager fragmentManager) {
    while (fragmentManager.getBackStackEntryCount() > 0) {
        fragmentManager.popBackStackImmediate();
    }
}

Save all your fragments in an ArrayList.

Initializing:

List<Fragment> activeCenterFragments = new ArrayList<Fragment>();

Adding fragment to list:

private void addCenterFragments(Fragment fragment) {
    fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.add(R.id.empty_center_layout, fragment);
    activeCenterFragments.add(fragment);
    fragmentTransaction.commit();
}

When you want to remove all them, do the following:

private void removeActiveCenterFragments() {
    if (activeCenterFragments.size() > 0) {
        fragmentTransaction = fragmentManager.beginTransaction();
        for (Fragment activeFragment : activeCenterFragments) {
            fragmentTransaction.remove(activeFragment);
        }
        activeCenterFragments.clear();
        fragmentTransaction.commit();
    }
}

I have used this method in production for years, and it works like a charm. Let me know if you have any questions.
