PopupMenu

A popup menu shows a rundown of things in a vertical rundown that is secured to the view that conjured the menu. It's useful for giving a flood of activities that identify with particular substance or to give choices to a second part of a summon. Activities in a popup menu ought not specifically influence the relating substance—that is the thing that relevant activities are for. Or maybe, the popup menu is for stretched out activities that identify with areas of substance in your action.

Example :-
               PopupMenu ppm = new PopupMenu(this,view);
               getMenuInflater().inflate(R.menu.main,ppm.getMenu());
                ppm.show();

Fragment code

  In Fragments there are two types are adding for Fragment .

 1) Static Fragment :-

Syntax : -
  xml :-              

      <?xml version="1.0" encoding="utf-8"?>

      <fragment  

       android:id="@+id/fragment1" 

       android:name="com.kiranapp.dynamicfragment" 

       android:layout_width="0px" 

       android:layout_height="match_parent" 

       android:layout_weight="1" /> 

  java :-
               Fragment frag=getFragmentManager().findFragmentByID(R.id.static_fragment);

 2) Dynamic Fragment :-

Syntax :-
 xml : -       

     <FrameLayout 

      android:layout_width="match_parent"     

      android:layout_height="wrap_content" 

      android:layout_marginTop="20dp" 

      android:id="@+id/myframe" 

      android:layout_gravity="center_horizontal" 

      android:background="#8a99c3">

    </FrameLayout>

 java : -         

     fragmentManager=getFragmentManager();
     dynamicfragment dynamifrag=new dynamicfragment();
     fragmentTransaction=fragmentManager.beginTransaction();
     fragmentTransaction.add(R.id.myframe,dynamifrag);
     fragmentTransaction.commit();    

    DynamicFragment :-

               Below code is example for  dynamicfragment . And i have taken another one xml    
               and java.
