Refresh a fragment android

Question

Earlier this code was working but it now it suddenly stopped working. Fragment is not detaching from parent activity.

public void reLoadFragment(Fragment fragment) { Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment"); // Reload current fragment Fragment frg = null; frg = getSupportFragmentManager().findFragmentByTag(fragment.getClass().getName()); frg.onDetach(); final FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); ft.detach(frg); ft.attach(frg); ft.commit(); Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment finish"); }

ft.detach() not working after support library update 25.1.0. This solution works fine after update:

getSupportFragmentManager().beginTransaction().detach(oldFragment).commitNowAllowingStateLoss(); getSupportFragmentManager().beginTransaction().attach(oldFragment).commitAllowingStateLoss();

Credit: Refresh or force redraw the fragment

This worked for me in refreshing current fragment. None of the above answers worked in my case.

You can simply refresh the current fragment using

FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.detach(this).attach(this).commit();

Also, in your case you can do something like this,

public void reLoadFragment(Fragment fragment) { Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment"); Fragment currentFragment = fragment; if (currentFragment instanceof "FRAGMENT CLASS NAME") { FragmentTransaction fragTransaction = (getActivity()).getFragmentManager().beginTransaction(); fragTransaction.detach(currentFragment); fragTransaction.attach(currentFragment); fragTransaction.commit(); Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment finish"); } else Log.i(LogGeneratorHelper.INFO_TAG, "fragment reloading failed"); }

Use this in yout Main Activity:

frag_name frag_name = new frag_name(); FragmentManager manager = this.getSupportFragmentManager(); manager.beginTransaction().replace(R.id.youtframelayout, frag_name, frag_name.getTag()).commit();

It inicializes the fragment and replaces it in your FrameLayout

Like this your replacing again the fragment :)

Hope it works! :)

thanks, i made it work like this. ft.detach() not working after support library update 25.1.0. This solution works fine after update: getSupportFragmentManager() .beginTransaction() .detach(oldFragment) .commitNowAllowingStateLoss(); getSupportFragmentManager() .beginTransaction() .attach(oldFragment) .commitAllowingStateLoss();

This will refresh current fragment :

 FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.detach(this).attach(this).commit();

For kotlin use below code.

 fragmentManager!!.beginTransaction().detach(this).attach(this).commit()

For kotlin:

supportFragmentManager.beginTransaction().detach(fragment).attach(fragment).commit()
