區隔可點按的廣告程式

您應該將播放器的UI邏輯與管理廣告點按的處理程式分開。 其中一個方法是為活動實作多個片段。

1. 實作一個片段以包含 MediaPlayer.

   此片段應該呼叫 notifyClick() 和將負責視訊播放。

   public class PlayerFragment extends SherlockFragment {
       ...
       public void notifyAdClick () {
           _mediaPlayer.notifyClick();
       }
       ...
   }
   

2. 實作不同的片段來顯示UI元素（表示廣告可點按）、監視該UI元素，並將使用者點按的片段傳達給包含 MediaPlayer.

   此片段應該宣告介面以進行片段通訊。 片段在其期間擷取介面實施 onAttach() 生命週期方法，並可呼叫介面方法來與活動通訊。

   public class PlayerClickableAdFragment extends SherlockFragment {
       private ViewGroup viewGroup;
       private Button button;
       OnAdUserInteraction callback;
       @Override
       public View onCreateView(LayoutInflater inflater,
                                ViewGroup container,
                                Bundle savedInstanceState) {
           // the custom fragment is defined by a custom button
           viewGroup = (ViewGroup) inflater.inflate(R.layout.fragment_player_clickable_ad,
                                                    container, false);
           button = (Button) viewGroup.findViewById(R.id.clickButton);
   
           // register a click listener to detect user interaction
           button.setOnClickListener(new View.OnClickListener() {
               @Override
               public void onClick(View v) {
                   // send the event back to the activity
                   callback.onAdClick();
               }
           });
           viewGroup.setVisibility(View.INVISIBLE);
           return viewGroup;
       }
   
       public void hide() {
           viewGroup.setVisibility(View.INVISIBLE);
       }
   
       public void show() {
           viewGroup.setVisibility(View.VISIBLE);
       }
   
       @Override
       public void onAttach(Activity activity) {
           super.onAttach(activity);
           // attaches the interface implementation
           // if the container activity does not implement the methods
           // from the interface an exception will be thrown
           try {
               callback = (OnAdUserInteraction) activity;
           } catch (ClassCastException e) {
               throw new ClassCastException(activity.toString()
                   + " must implement OnAdUserInteraction");
           }
       }
   
       // user defined interface that allows fragment communication
       // must be implemented by the container activity
       public interface OnAdUserInteraction {
           public void onAdClick();
       }
   }
