Cannot cast 'android.view.View' to 'com.example.shabeer.listview.ListView'

I get an error in this line here

list_view = (ListView)findViewById(R.id.listView_id); shows error

inconvertible type; cannot cast android.view.View to com.example.shabeer.listview.ListView

also the list_view.setAdapter(adapter); is not working.

ListView class:

package com.example.shabeer.listview;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;

public class ListView extends AppCompatActivity {

    public static ListView list_view;
    private static String[] NAMES = new String[] { "Tom", "John", "Jack", "Pal"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_list_view);
    }

    public void listView(){
         list_view = (ListView)findViewById(R.id.listView_id);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.name_list, NAMES);
        list_view.setAdapter(adapter);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_list_view, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

activity_list_view.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

You cannot cast an Android listview to your own listview.

Instead of "com.example.shabeer.listview.ListView" you need a "android.widget.ListView". This is the one you are referencing in your xml layout file.

public static android.widget.ListView list_view;

and

list_view = (android.widget.ListView)findViewById(R.id.listView_id);
