How do I get the currently displayed fragment?

Question

I am playing with fragments in Android.

I know I can change a fragment by using the following code:

FragmentManager fragMgr = getSupportFragmentManag         


        

Answer 1

If get here and you are using Kotlin:

var fragment = supportFragmentManager.findFragmentById(R.id.fragment_container)

R.id.fragment_container is the id where the fragment is presenting on their activity

Or if you want a nicer solution:

supportFragmentManager.findFragmentById(R.id.content_main)?.let {
    // the fragment exists

    if (it is FooFragment) {
        // The presented fragment is FooFragment type
    }
}
