在RecyclerView中无法播放视频或音频的VideoView
在RecyclerView中无法播放视频或音频的VideoView
提问于 2015-12-12 03:17:21
嗨，我正在尝试创建一个视频日志片段，它有一个回收视图，其中包含标题，情绪和每个列表项目中的视频。由于某些原因，videoview甚至没有出现。videofilePath保存正确，我已经使用println语句进行了检查。我没有收到任何错误，但它只是完全崩溃。下一个列表项在视频显示之前开始。
这是我的ViewHolder类
public class JournalViewHolder extends RecyclerView.ViewHolder{
private TextView title;
private TextView mood;
private VideoView mVideoView;
MediaController mMediaController;
Context mContext;
public JournalViewHolder(View view, Context context){
super(view);
mContext = context;
title = (TextView)view.findViewById(R.id.JournalTitle);
mood = (TextView)view.findViewById(R.id.JournalMood);
mVideoView = (VideoView)view.findViewById(R.id.JournalVideo);
mMediaController = new MediaController(context);
}
public void bind(JournalEntry journalEntry){
title.setText(journalEntry.getTitle());
mood.setText(journalEntry.getMood());
if(journalEntry.getVideoFileName() != null){
Uri uri = Uri.parse(journalEntry.getVideoFileName());
mVideoView.setVideoURI(uri);
mVideoView.requestFocus();
mVideoView.setMediaController(mMediaController);
mVideoView.setZOrderOnTop(true);
mVideoView.start();
}
}}
下面是我的适配器类
public class JournalRecyclerViewAdapter extends RecyclerView.Adapter<JournalViewHolder> {专用列表mContext；专用上下文列表；
public JournalRecyclerViewAdapter(List<JournalEntry> entries, Context context){
mJournalEntries = entries;
mContext = context;
}
@Override
public JournalViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View view = inflater.inflate(R.layout.journal_list_items, parent, false);
JournalViewHolder holder = new JournalViewHolder(view, mContext);
return holder;
}
@Override
public void onBindViewHolder(JournalViewHolder holder, int position) {
JournalEntry entry = mJournalEntries.get(position);
holder.bind(entry);
}
@Override
public int getItemCount() {
return mJournalEntries.size();
}}
下面是我的类，它初始化项目列表和回收器视图
public class JournalView extends FragmentLoggingLifeCycler {
private RecyclerView mRecyclerView;
DataAccess mDataAccess;
List<JournalEntry> mEntryList;
public static final String USERNAME_KEY = "username";
public static final String PASSWORD_KEY = "password";
String password;
String username;
User currentUser;
private Context mContext;
public JournalView() {
// Required empty public constructor
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
mContext = activity.getApplicationContext();
}
@Override
public void onAttach(Context context) {
super.onAttach(context);
mContext = context;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_journal_view, container, false);
Bundle data = getArguments();
username = data.getString(USERNAME_KEY);
password = data.getString(PASSWORD_KEY);
LinearLayoutManager manager = new LinearLayoutManager(getActivity());
mDataAccess = DataAccess.getDataAccess(container.getContext());
currentUser = mDataAccess.getLoginUser(username, password);
mEntryList = mDataAccess.getAllJournals();
//mDataAccess.mDatabase.delete(Scheme.Journal.NAME, null, null);
// mEntryList = trimList(mEntryList, currentUser.getUsername());
// for(int counter = 0; counter < mEntryList.size(); counter++){
// System.out.println(mEntryList.get(counter).getTitle());
// }
mRecyclerView = (RecyclerView)view.findViewById(R.id.JournalList);
mRecyclerView.setLayoutManager(manager);
mRecyclerView.setAdapter(new JournalRecyclerViewAdapter(mEntryList, mContext));
return view;
}
private static List<JournalEntry> trimList(List<JournalEntry> entries, String username){
List<JournalEntry> returnedList = new ArrayList<>();
for(int i = 0; i< returnedList.size(); i++){
System.out.println(entries.get(i).getUsername()+ ", " +username);
if(entries.get(i).getUsername().equals(username)){
returnedList.add(entries.get(i));
}
}
return returnedList;
}}
下面是我的XML文件。

我正在开发一个名为OneItem的库，它可能会对您有所帮助。
https://github.com/tbrand/OneItem
在#selectItemAt(int position)中，开始使用任意VideoView(如MediaPlayer或ExoPlayer)播放视频。
在#UnSelectItemAt(int position)中，停止播放视频并释放它。
