我的Activity继承另一个Activity并包含导航抽屉，其中每个选项打开一个新的fragment。我想将Youtube集成到其中一个fragment中。以前我使用YouTubePlayerView将Youtube集成到Activity中，但这里需要在Fragment中实现。我在网上搜索并找到了YouTubePlayerFragment可以将Youtube集成到Fragment中。但是当我在教程中搜索时，我发现即使使用YouTubePlayerFragment，我们也会扩展YouTubeBaseActivity。以下是这些示例...

我无法理解如何使用YouTubePlayerFragment，使我的类扩展Fragment而不是我的项目所需的YouTubeBaseActivity。正如下面所示，我的类扩展另一个Activity，并包含导航抽屉，在第五个选项中打开YouTube Fragment。我想在此片段内播放Youtube视频。我简要介绍一下我的类布局-
public class LandingActivity extends BaseGActivity {
.
.
.
.
public void selectDrawerItem(int position) {
Bundle args = new Bundle();
switch (position) {
case 0:
currentFragment = new HomeFragment_();
args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_ALL);
GApplication.getInstance().stopGPlayer();
break;
case 1:
currentFragment = new HomeFragment_();
args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_PHOTO);
GApplication.getInstance().stopGPlayer();
break;
//
case 2:
currentFragment = new HomeFragment_();
args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_AUDIO);
GApplication.getInstance().stopGPlayer();
break;
case 3:
currentFragment = new HomeFragment_();
args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_VIDEO);
GApplication.getInstance().stopGPlayer();
break;
case 4:
currentFragment = new HomeFragment_();
args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_MEME);
GApplication.getInstance().stopGPlayer();
break;
case 5:
currentFragment = new YoutubeFragment();
default:
currentFragment = new HomeFragment_();
args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_ALL);
GApplication.getInstance().stopGPlayer();
break;
}
currentFragment.setArguments(args);
FragmentManager frgManager = getFragmentManager();
frgManager.beginTransaction().replace(R.id.content_frame, currentFragment)
.commit();
mDrawerList.setItemChecked(position, true);
setTitle(dataList.get(position).getItemName());
mDrawerLayout.closeDrawers();
}
public class YoutubeFragment extends Fragment implements YouTubePlayer.OnInitializedListener{

if (!wasRestored) {

YPlayer.play();
}
}
}
YouTubeFragment.java

布局

错误-
