how can i use intent in ListFragment?

Question

I am creating a app.I've used a tablayout with fragments,extended one of the fragments with ListFragment and wanted to give intent inside that fragment,i used the following...

home_fragment.java

package com.example.mymehnat;

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.view.LayoutInflater;
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 implements AdapterView.OnItemClickListener {

ListView lst;

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

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    ArrayAdapter adapter = ArrayAdapter.createFromResource(home_fragment.this.getActivity(), R.array.songs, android.R.layout.simple_list_item_1);
    setListAdapter(adapter);
    getListView().setOnItemClickListener(this);
}

@Override
public void onItemClick(AdapterView<?> adapter, View view,int position, long l) {
    Intent intent = new Intent(home_fragment.this.getActivity(), Lyrics.class);
    intent.putExtra("SongName", lst.getItemAtPosition(position).toString());
    lst.getContext().startActivity(intent);

}

}

home_fragment.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/background">

<ListView
   android:layout_width="wrap_content"
   android:layout_height="match_parent"
   android:id="@android:id/list">

</ListView>
</LinearLayout>

but whenever I click any item on the list it doesn't work,shows nothing and prompted me an error...

    E/MessageQueue-JNI: java.lang.NullPointerException: Attempt to invoke             virtual method 'java.lang.Object android.widget.ListView.getItemAtPosition(int)' on a null object reference
    at com.example.mymehnat.home_fragment.onItemClick(home_fragment.java:36) and so on

please help me.
your help is highly appreciated.

You didn't initialize the ListView lst

Try to do like this. This need to be declared under the OnCreateView

lst = v.findViewById(R.id.list)

hey I tried what you said while doing that it says Cannot resolve symbol list which is the id of list,so I created a value id resource as list and after that the symbol problem is solved but it still dragging me into the same – john mantraj Jul 15 '19 at 06:12
