      <?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 :-

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
FragmentManager fragmentManager;
FragmentTransaction fragmentTransaction;

@Override protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 fragmentManager=getFragmentManager();
 dynamicfragment dynamifrag=new dynamicfragment();
 fragmentTransaction=fragmentManager.beginTransaction();
 fragmentTransaction.add(R.id.myframe,dynamifrag);

    Button b1;
@Nullable

@Override 

 public View onCreateView(LayoutInflater inflater, ViewGroup container, 

                                                      Bundle savedInstanceState) {
 return inflater.inflate(R.layout.dyanamicfragment,container,false);
 }
@Override 

 public void onActivityCreated(Bundle savedInstanceState) {
 super.onActivityCreated(savedInstanceState);
 b1=(Button)getActivity().findViewById(R.id.button);
