my problem::

• In the line alert.show(getFragmentManager(), "Alert_Dialog");
• I am getting error as The method show(FragmentManager, String) in the type DialogFragment is not applicable for the arguments (FragmentManager, String)
• How to resolve this so that i am able to pop the fragment

Answer 1

As you're using android.support.v4.app.DialogFragment, you should pass to show() an instance of android.support.v4.app.FragmentManager which can be queried using an getSupportFragmentManager() call instead of getFragmentManager().

Answer 2

Replace getFragmentManager() with getSupportFragmentManager().
