我正在开发一个安卓应用程序。在此应用程序中，我希望使用 AppCompatActivity 在 ListView 或 RecyclerView 中使用 youtube 播放器播放 youtube 视频。我使用了 YouTubeBaseActivity，它与此配合使用效果很好，但我需要 AppCompatActivity。所以我使用 YouTubePlayerFragment 或 YouTubePlayerSupportFragment 来解决我的问题。
当我将 YouTubePlayerFragment 与 AppCompatActivity 一起使用时，它运行良好。但是我想在 ListView 中使用它，但出现以下错误。
android.view.InflateException: Binary XML file line #8: Binary XML file line #8: Error inflating class fragment

所以，请告诉我我哪里错了？如何解决我的问题？
提前致谢。
更新 1:
我正在使用@azizbekian 解决方案。这解决了我的膨胀异常问题，但我有多个布局的相同视频。
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view;
YouTubePlayerFragment youtubeFragment;
LayoutInflater inflater = (LayoutInflater) aContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
View temp = inflater.inflate(R.layout.custom_frag_youtube_list, parent, false);
final int id = View.generateViewId();
temp.setId(id);
youtubeFragment = YouTubePlayerFragment.newInstance();
aActivity.getFragmentManager()
.beginTransaction()
.replace(id, youtubeFragment)
.commit();
view = temp;
view.setTag(youtubeFragment);
} else {
view = convertView;
youtubeFragment = (YouTubePlayerFragment)view.getTag();
}
youtubeFragment.initialize(YOUTUBE_API_KEY,
new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,
YouTubePlayer youTubePlayer, boolean b) {
// do any work here to cue video, play video, etc.
Log.e("Youtube Position: ",""+position);
Log.e("Youtube list value: ",""+aList.get(position));
youTubePlayer.cueVideo(aList.get(position));
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult youTubeInitializationResult) {
}
});
return view;
}
日志值:
Youtube Position:: 0
Youtube list value:: KSGYVl4ZgRs
Youtube Position:: 1
Youtube list value:: nCgQDjiotG0
更新 2:
我已经解决了所有问题而不是一个问题。如果我在播放一个视频后播放视频，那么时间适配器不会刷新。所以我无法一次处理视频播放。
更新 3:
经过大量搜索和@azizbekian 解决方案后，我已经解决了我的问题。通过使用以下解决方案。
@Override
public View getView(final int position, View convertView, final ViewGroup parent) {
final mHolder holder;
final View fview;
final LayoutInflater inflater = (LayoutInflater) aContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
holder = new mHolder();
fview = inflater.inflate(R.layout.custom_youtube_frag_listview_list, parent, false);
holder.mLoaderFrame = (ImageView) fview.findViewById(R.id.imgLayer1);
fview.setTag(holder);
} else {
fview = convertView;
holder = (mHolder) fview.getTag();
}
String VideoID = aList.get(position);
/**

*/
String mURL = YOUTUBE_THUMBNAIL_URL_VIDEO1 + VideoID + YOUTUBE_THUMBNAIL_URL_VIDEO2;
Glide.with(aContext).load(mURL).into(holder.mLoaderFrame);
holder.mLoaderFrame.setVisibility(View.VISIBLE);
if(mCounterLeaveremove != 0){
int mId = position+1;
if(mCounterLeaveremove != mId){
FragmentManager fragmentManager = aActivity.getFragmentManager();
Fragment oldFragment = null;
try {
oldFragment = fragmentManager.findFragmentById(mId);
} catch (Exception e) {
e.printStackTrace();
}
if(oldFragment != null) {
// Delete fragmet from ui, do not forget commit() otherwise no action
// is going to be observed
fragmentManager.beginTransaction().remove(oldFragment).commit();
}
}
}
holder.mLoaderFrame.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mCounterLeaveremove = position+1;
notifyDataSetChanged();
YouTubePlayerFragment youtubeFragment;
final int id = position+1;
fview.setId(id);
youtubeFragment = YouTubePlayerFragment.newInstance();
aActivity.getFragmentManager()
.beginTransaction()
.replace(id, youtubeFragment)
.commit();
youtubeFragment.initialize(YOUTUBE_API_KEY,
new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,
YouTubePlayer youTubePlayer, boolean b) {
Log.e("Youtube Position: ", "" + position);
Log.e("Youtube list value: ", "" + aList.get(position));
holder.mLoaderFrame.setVisibility(View.GONE);
String VideoID = aList.get(position);
youTubePlayer.loadVideo(VideoID);
youTubePlayer.setOnFullscreenListener(new YouTubePlayer.OnFullscreenListener() {
@Override
public void onFullscreen(boolean b) {
}
});
youTubePlayer.addFullscreenControlFlag(0);
/**

*/
new custom_youtube_list_adapter.MyPlayerStateChangeListener(holder.mLoaderFrame);
new custom_youtube_list_adapter.MyPlaybackEventListener(holder.mLoaderFrame);
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult youTubeInitializationResult) {
}
});
}
});
return fview;
}
要获取 youtube 视频缩略图，你可以去 throw。
How do I get a YouTube video thumbnail from the YouTube API?
最佳答案
Caused by: java.lang.IllegalArgumentException: Binary XML file line #8: Duplicate id 0x7f0b0063, tag null, or parent id 0x7f0b0062 with another fragment for com.google.android.youtube.player.YouTubePlayerFragment
问题是，您正试图膨胀具有相同 ID 的多个 fragment ，这是不可能的。因此，不是将 YouTubePlayerFragment 添加到 xml 文件中，而是在 java 代码中创建它。因此，custom_frag_youtube_list.xml 将更改为以下内容:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
然后在你的适配器中:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
...
View view;
YouTubePlayerFragment youtubeFragment;
if (convertView == null) {
View temp = inflater.inflate(R.layout.custom_frag_youtube_list, parent, false);
final int id = View.generateViewId();
temp.setId(id);
youtubeFragment = YouTubePlayerFragment.newInstance();
activity.getFragmentManager()
.beginTransaction()
.replace(id, youtubeFragment)
.commit();
view = temp;
view.setTag(youtubeFragment);
} else {
view = convertView;
youtubeFragment = view.getTag();
}
// interact with youtubeFragment
...
return view;
}
更新
根据 this thread 判断，Google 似乎不允许同时播放多个 YouTube 视频。
关于java - ListView 中的 YouTubePlayerFragment 出现 AppCompatActivity 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45512649/
