Custom List View with Cursor Adapter not working

I want to create a custom listview with SQLite database. Later I will add buttons on the listitem as well. It seems to be simple. But I'm trying it for a long time and it's not working. Can anyone please help me out where I am making the mistake?

Here are my Code

MyActivity.java

import android.app.Activity;
import android.app.ListActivity;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;

import java.lang.reflect.Array;
import java.util.ArrayList;
import java.util.List;

public class MainActivity extends ListActivity {

    MyCursorAdapter customAdapter;
    private Cursor mCursor;
    private ListView listView;

    // Default constructor
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);

       // listView = (ListView) findViewById(R.id.activity_main);

        DBHelper dbh= new DBHelper(this);
        mCursor= (Cursor) dbh.getAllCotacts();
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> a, View v, int position, long id) {
            }
        });


        new Handler().post(new Runnable() {

            //@Override
            public void run() {
                customAdapter = new MyCursorAdapter(MainActivity.this, mCursor, 0);

                listView.setAdapter(customAdapter);
            }

        });
    }

}
