Answer 1

Hey friends I got the solution of above problem.Here I post my full source code so that others can use this solution.

1.Create one acyivity i.e CameraPictureActivity.

            public class CameraPictureActivity extends Activity {
                Button addImage;
                ArrayList imageArry = new ArrayList();
                ContactImageAdapter imageAdapter;
                private static final int CAMERA_REQUEST = 1;

                ListView dataList;
                byte[] imageName;
                int imageId;
                Bitmap theImage;
                DataBaseHandler db;

                /** Called when the activity is first created. */
                @Override
                public void onCreate(Bundle savedInstanceState) {
                    super.onCreate(savedInstanceState);
                    setContentView(R.layout.main);
                    dataList = (ListView) findViewById(R.id.list);
                    /**
                     * create DatabaseHandler object
                     */
                    db = new DataBaseHandler(this);
                    /**
                     * Reading and getting all records from database
                     */
                    List contacts = db.getAllContacts();
                    for (Contact cn : contacts) {
                        String log = "ID:" + cn.getID() + " Name: " + cn.getName()
                                + " ,Image: " + cn.getImage();

                        // Writing Contacts to log
                        Log.d("Result: ", log);
                        // add contacts data in arrayList
                        imageArry.add(cn);

                    }
                    /**
                     * Set Data base Item into listview
                     */
                    imageAdapter = new ContactImageAdapter(this, R.layout.screen_list,
                            imageArry);
                    dataList.setAdapter(imageAdapter);

                    /**
                     * open dialog for choose camera
                     */

                    final String[] option = new String[] {"Take from Camera"};
                    ArrayAdapter adapter = new ArrayAdapter(this,
                            android.R.layout.select_dialog_item, option);
                    AlertDialog.Builder builder = new AlertDialog.Builder(this);

                    builder.setTitle("Select Option");
                    builder.setAdapter(adapter, new DialogInterface.OnClickListener() {

                        public void onClick(DialogInterface dialog, int which) {
                            // TODO Auto-generated method stub
                            Log.e("Selected Item", String.valueOf(which));
                            if (which == 0) {
                                callCamera();
                            }


                        }
                    });
                    final AlertDialog dialog = builder.create();

                    addImage = (Button) findViewById(R.id.btnAdd);

                    addImage.setOnClickListener(new View.OnClickListener() {
                        public void onClick(View v) {
                            dialog.show();
                        }
                    });

                }

                /**
                 * On activity result
                 */
                @Override
                protected void onActivityResult(int requestCode, int resultCode, Intent data) {
                    if (resultCode != RESULT_OK)
                        return;

                    switch (requestCode) {
                    case CAMERA_REQUEST:

                        Bundle extras = data.getExtras();

                        if (extras != null) {
                            Bitmap yourImage = extras.getParcelable("data");
                            // convert bitmap to byte
                            ByteArrayOutputStream stream = new ByteArrayOutputStream();
                            yourImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
                            byte imageInByte[] = stream.toByteArray();

                            // Inserting Contacts
                            Log.d("Insert: ", "Inserting ..");
                            db.addContact(new Contact("Android", imageInByte));
                            Intent i = new Intent(CameraPictureActivity.this,
                                    CameraPictureActivity.class);
                            startActivity(i);
                            finish();

                        }
                        break;
                    }
                }

                /**
                 * open camera method
                 */
                public void callCamera()
                {
                    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    startActivityForResult(intent, CAMERA_REQUEST);
                    intent.setType("image/*");
                    intent.putExtra("crop", "true");
                    intent.putExtra("aspectX", 0);
                    intent.putExtra("aspectY", 0);
                    intent.putExtra("outputX", 250);
                    intent.putExtra("outputY", 200);
                }
                }

2.Create class DataBaseHandler.

             public class DataBaseHandler extends SQLiteOpenHelper 
             {

            // All Static variables
            // Database Version
            private static final int DATABASE_VERSION = 1;

            // Database Name
            private static final String DATABASE_NAME = " Camera_imagedb";

            // Contacts table name
            private static final String TABLE_CONTACTS = " Camera_contacts";

            // Contacts Table Columns names
            private static final String KEY_ID = "id";
            private static final String KEY_NAME = "name";
            private static final String KEY_IMAGE = "image";

            public DataBaseHandler(Context context) {
                super(context, DATABASE_NAME, null, DATABASE_VERSION);
            }

            // Creating Tables
            @Override
            public void onCreate(SQLiteDatabase db) {
                String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_CONTACTS + "("
                        + KEY_ID + " INTEGER PRIMARY KEY," + KEY_NAME + " TEXT,"
                        + KEY_IMAGE + " BLOB" + ")";
                db.execSQL(CREATE_CONTACTS_TABLE);
            }

            // Upgrading database
            @Override
            public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
                // Drop older table if existed
                db.execSQL("DROP TABLE IF EXISTS " + TABLE_CONTACTS);

                // Create tables again
                onCreate(db);
            }

            /**
             * All CRUD(Create, Read) Operations
             */

            public// Adding new contact
            void addContact(Contact contact) {
                SQLiteDatabase db = this.getWritableDatabase();

                ContentValues values = new ContentValues();
                values.put(KEY_NAME, contact._name); // Contact Name
                values.put(KEY_IMAGE, contact._image); // Contact Phone

                // Inserting Row
                db.insert(TABLE_CONTACTS, null, values);
                db.close(); // Closing database connection
            }

            // Getting single contact
            Contact getContact(int id) {
                SQLiteDatabase db = this.getReadableDatabase();

                Cursor cursor = db.query(TABLE_CONTACTS, new String[] { KEY_ID,
                        KEY_NAME, KEY_IMAGE }, KEY_ID + "=?",
                        new String[] { String.valueOf(id) }, null, null, null, null);
                if (cursor != null)
                    cursor.moveToFirst();

                Contact contact = new Contact(Integer.parseInt(cursor.getString(0)),
                        cursor.getString(1), cursor.getBlob(1));

                // return contact
                return contact;

            }

            // Getting All Contacts
            public List getAllContacts() {
                List contactList = new ArrayList();
                // Select All Query
                String selectQuery = "SELECT  * FROM contacts ORDER BY name";

                SQLiteDatabase db = this.getWritableDatabase();
                Cursor cursor = db.rawQuery(selectQuery, null);
                // looping through all rows and adding to list
                if (cursor.moveToFirst()) {
                    do {
                        Contact contact = new Contact();
                        contact.setID(Integer.parseInt(cursor.getString(0)));
                        contact.setName(cursor.getString(1));
                        contact.setImage(cursor.getBlob(2));
                        // Adding contact to list
                        contactList.add(contact);
                    } while (cursor.moveToNext());
                }
                // close inserting data from database
                db.close();
                // return contact list
                return contactList;
            }
            }

3.create another class Contact

        public class Contact 
        {

            // private variables
            int _id;
            String _name;
            byte[] _image;

            // Empty constructor
            public Contact() {

            }

            // constructor
            public Contact(int keyId, String name, byte[] image) {
                this._id = keyId;
                this._name = name;
                this._image = image;

            }
            public Contact(String name, byte[] image) {
                this._name = name;
                this._image = image;

            }
            public Contact(int keyId) {
                this._id = keyId;

            }

            // getting ID
            public int getID() {
                return this._id;
            }

            // setting id
            public void setID(int keyId) {
                this._id = keyId;
            }

            // getting name
            public String getName() {
                return this._name;
            }

            // setting name
            public void setName(String name) {
                this._name = name;
            }

            // getting phone number
            public byte[] getImage() {
                return this._image;
            }

            // setting phone number
            public void setImage(byte[] image) {
                this._image = image;
            }
        }

4.create one adapter i.e ContactImageAdapter

        public class ContactImageAdapter extends ArrayAdapter{
             Context context;
                int layoutResourceId;   
               // BcardImage data[] = null;
                ArrayList data=new ArrayList();
                public ContactImageAdapter(Context context, int layoutResourceId, ArrayList data) {
                    super(context, layoutResourceId, data);
                    this.layoutResourceId = layoutResourceId;
                    this.context = context;
                    this.data = data;
                }

                @Override
                public View getView(int position, View convertView, ViewGroup parent) {
                    View row = convertView;
                    ImageHolder holder = null;

                    if(row == null)
                    {
                        LayoutInflater inflater = ((Activity)context).getLayoutInflater();
                        row = inflater.inflate(layoutResourceId, parent, false);

                        holder = new ImageHolder();
                        holder.txtTitle = (TextView)row.findViewById(R.id.txtTitle);
                        holder.imgIcon = (ImageView)row.findViewById(R.id.imgIcon);
                        row.setTag(holder);
                    }
                    else
                    {
                        holder = (ImageHolder)row.getTag();
                    }

                    Contact picture = data.get(position);
                    holder.txtTitle.setText(picture._name);
                    //convert byte to bitmap take from contact class

                    byte[] outImage=picture._image;
                    ByteArrayInputStream imageStream = new ByteArrayInputStream(outImage);
                    Bitmap theImage = BitmapFactory.decodeStream(imageStream);
                    holder.imgIcon.setImageBitmap(theImage);
                   return row;

                }

                static class ImageHolder
                {
                    ImageView imgIcon;
                    TextView txtTitle;
                }
            }

5.Finally create the xml files main and screen_list .

5.1 main.xml

5.2 screen_list.xml

6.Output like this.
