Xây dựng và tủy chỉnh một ActionBar trong lập trình android

[kulu193]

bài viết này long sẽ tự tạo cho chính ứng dụng của mình một đối tượng như là đối tượng actionbar của android. và tất nhiên đối tượng này do chính mình tạo ra thì mọi quyền hạn cũng như "luật chơi" là do chính như yêu cầu mà mình mong muốn không phải sự cho phép của android.

3) actionbar là gì:
- như hình ảnh bên trên vậy, actionbar như là thanh tiêu đề của trang trong ứng dụng hiện tại. mà mỗi trang như vậy nó lại có một tiêu đề cũng như có các nút chức năng hoàn toàn khác nhau.
- chức năng mỗi nút là do chính mình hay do phía khách hàng đặt app quyết định.
- từ phiên android lever 11 trở đi (android 3.0 trở đi) thì android có hỗ trợ đối tượng actionbar.

4) mô tả thông tin thêm:
- trong demo này không sử dụng đối tượng actionbar của thư viện android
- trong demo này actionbar là một tập hợp từ các layout và đối tượng cơ bản (textview, imageview, linearlayout, ...)
- đối tượng myactionbar trong demo này còn thiết lập các sự kiện lắng nghe khi bạn click vào đối tượng.
