android - Correct way to remove all (Child) fragments -

i load bunch of child fragments dynamically inside parent's fragment linearlayout (fragmentcontainer), when user clicks button, need remove them , add new ones. don't know exact number of fragments added each time. way of removing fragments @ once

linearlayout ll = (linearlayout) view.findviewbyid(r.id.fragmentcontainer); ll.removeallviews(); 

now can add new ones using fragment transaction methods. way of removing fragments super easy , works me better removing each fragment 1 one using remove() practice? how performance? recommend better way?

this way of removing fragments @ once

no, isn't. way of removing views container.

this way of removing fragments super easy , works me.

it remove fragments. removes views. why method named removeallviews().

but practice?

no. starters, when rotate device or undergo configuration change, notice "removed" fragments come back.

do recommend better way?

keep track of outstanding fragments (e.g., using arraylist<fragment>), iterate on list, passing each remove() method on fragmenttransaction.
