   home_fragment.java

   package com.example.mymehnat;

   import android.content.Intent;
   import android.os.Bundle;

   import android.view.View;
   import android.view.ViewGroup;
   import android.widget.AdapterView;
   import android.widget.ArrayAdapter;
   import android.widget.ListView;

   public class home_fragment extends ListFragment {

   ListView lst;

   @Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   View v = inflater.inflate(R.layout.home_fragment, container, false);
   lst = v.findViewById(android.R.id.list);
   return v;
   }

   @Override
   public void onActivityCreated(Bundle savedInstanceState) {
   super.onActivityCreated(savedInstanceState);
   ArrayAdapter adapter = ArrayAdapter.createFromResource(getActivity(), R.array.songs, android.R.layout.simple_list_item_1);
   setListAdapter(adapter);

   getListView().setOnItemClickListener(new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView adapterView, View view, int i, long l) {
   Intent intent = new Intent(getActivity(), Lyrics.class);
   intent.putExtra(“SongName”, lst.getItemAtPosition(i).toString());
   startActivity(intent);
   }
   });
   }

   }

   @Override
   public boolean onCreateOptionsMenu(Menu menu) {

   getMenuInflater().inflate(R.menu.menu,menu);

   MenuItem item=menu.findItem(R.id.item_search);
   SearchView searchView=(SearchView)item.getActionView();
   searchView.setQueryHint(“Search”);
   searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
   @Override
   public boolean onQueryTextSubmit(String s) {

   return false;
   }

   @Override
   public boolean onQueryTextChange(String s) {

   return true;
   }
   });
   return super.onCreateOptionsMenu(menu);
   }
   }

   I wanted to add a searchbar in my MainActivity and search the items in my listview inside home_fragment(Fragment).
   the search bar is added successfully but its not functioning..

   please help me..
   I’m stuck on this for many days..
