Android - How to populate all images from SQLite to ListView in a simple way after Camera takes a photo?

I have spent a week reading a lot of questions and answers, tutorials, android documentations, videos etc. but still a lot of them are complicated, highly personalized examples with complicated data structures, interfaces and highly customized adapters of how to set all images retrieved from SQLite database to a listview. I just want a very direct, simple way of setting all my images from SQLite database to show on a simple listview. Android documentation does not have a very clear and complete example on this as well. My program has no highly customized adapter, no all those fancy data structures. I am sure that my question will benefit a lot of people trying to do the same thing because trust me I have browsed through many documentations, methods, tutorials, videos on youtube, and many questions and answers out there but none have a straightforward, understandable way to simply populate all the images from an SQLite to a ListView using just one class.

What this program is supposed to do is when it starts up, and when the camera icon on the activity bar is clicked, a camera will be opened and if a user takes a photo and oks to save it the picture will be saved in the database and the photo will be shown on the main page as a thumbnail in a ListView immediately after the camera instance is gone. I have tried viewing the database using adb and the storing mechanism is right, just the populating part is not.

So what is a simple way of populating all images from SQLite database to ListView?

I have tried many fancy ways as a result spent a lot of days in the process. So I have reverted back to this simpler code example that works so far below so it won't complicate your answering effort.

Below are my codes:

MainActivity:

import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.provider.MediaStore;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import java.io.ByteArrayOutputStream;


public class MainActivity extends ActionBarActivity {

    static final int REQUEST_IMAGE_CAPTURE = 1;
    SQLiteDatabase db;
    private ListView listView;
    private SimpleCursorAdapter adapter;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        db = this.openOrCreateDatabase("images.db", Context.MODE_PRIVATE, null);
        db.execSQL("create table if not exists tb (   image blob)");    

    }

    @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_main, menu);
        //dispatchTakePictureIntent();
        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) {
            //Calling dispatchTakePictureIntent to start the camera activity
            dispatchTakePictureIntent();
            return true;
        }

        return super.onOptionsItemSelected(item);

    }


    private void dispatchTakePictureIntent() {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {

            Bundle extras = data.getExtras();
            Bitmap imageTaken = (Bitmap) extras.get("data");

            ContentValues values = new ContentValues();

           byte[] toValuesPut = this.getBytes(imageTaken);
            values.put("image", toValuesPut);
            db.insert("tb", null, values);
            getImage();              

            db.close();
        }

    }

    protected void getImage(){
        listView = (ListView) findViewById(R.id.parentListView);
        Cursor c = db.rawQuery("select * from tb", null);
        //startManagingCursor(c);
        if(c.moveToNext()) {
            byte[] image = c.getBlob(0);
            Bitmap bmp = BitmapFactory.decodeByteArray(image, 0, image.length);
            ImageView thumb1 = (ImageView) findViewById(R.id.child2);
            thumb1.setImageBitmap(bmp);
        }    
    }

    public static byte[] getBytes(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 0, stream);
        return stream.toByteArray();
    }    
}
