【问题描述】：

我有一个带有缩略图和文本的水平回收器视图。单击缩略图图像时，应播放相应的视频。我能够显示图像和文本，现在我无法继续播放视频。任何帮助将不胜感激。

主要活动

 public class MainActivity extends AppCompatActivity 

private RecyclerView horizontal_recycler_view;
private ArrayList<String> horizontalList;
private HorizontalAdapter horizontalAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    horizontal_recycler_view = (RecyclerView) findViewById(R.id.horizontal_recycler_view);

    horizontalList = new ArrayList<>();
    horizontalList.add("horizontal 1");
    horizontalList.add("horizontal 2");
    horizontalList.add("horizontal 3");
    horizontalList.add("horizontal 4");
    horizontalList.add("horizontal 5");

    horizontalAdapter = new HorizontalAdapter(this, horizontalList);


    LinearLayoutManager horizontalLayoutManager
            = new LinearLayoutManager(MainActivity.this, LinearLayoutManager.HORIZONTAL, false);
    horizontal_recycler_view.setLayoutManager(horizontalLayoutManager);

    horizontal_recycler_view.setAdapter(horizontalAdapter);

适配器

    public class HorizontalAdapter extends RecyclerView.Adapter<HorizontalAdapter.MyViewHolder> 

private List<String> horizontalList;
Context ctxt;


public HorizontalAdapter(Context context, List<String> horizontalList) 
    this.ctxt = context;
    this.horizontalList = horizontalList;



@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) 
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.horizontal_item_view, parent, false);

    return new MyViewHolder(itemView);


@Override
public void onBindViewHolder(final MyViewHolder holder, final int position) 
    holder.txtView.setText(horizontalList.get(position));

    holder.imgView.setImageResource(R.drawable.thumbnail);

    holder.txtView.setOnClickListener(new View.OnClickListener() 
        @Override
        public void onClick(View v) 
            Toast.makeText(ctxt, holder.txtView.getText().toString(), Toast.LENGTH_SHORT).show();
        
    );


@Override
public int getItemCount() 
    return horizontalList.size();


public class MyViewHolder extends RecyclerView.ViewHolder 
    public TextView txtView;
    public ImageView imgView;


    public MyViewHolder(View view) 
        super(view);
        imgView = (ImageView) view.findViewById(R.id.thumbnail);
        txtView = (TextView) view.findViewById(R.id.video_title);

    

【问题讨论】：

你想在另一个活动中播放视频吗？还是在单元格中？

在另一个活动中

获取点击索引视频的绝对路径并传递给下一个活动并使用androidbegin.com/tutorial/…播放

不好意思问我看不懂...能不能说的再清楚点或者举个例子...

【参考方案1】：

Main Activity in --->>

    recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
    recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, true));
    recyclerView.setAdapter(new Top_ServiceAdapter());

---->Adapter in you horizontal_item_view.xml layout in 

linearlayout in image or text  with orientation vertical .... so done this problem

【参考方案2】：

您应该首先创建一个包含：“title”、“videoUrl”、“thumbnail_url”的类Item

那么你的水平列表将是一个列表

private List<Item> horizontalList;

然后在您的 viewHolder 上，您获取 videoUrl 并打开新 Activity，其意图是在其捆绑包中包含视频 url。

    Intent intent = new Intent(ctxt, VideoActivity.class);
    intent.putExtra("VIDEO_URL", item.videoUrl);
    startActivity(intent);

然后在您的 VideoActivity 上，您应该实现一个 videoPlayer 库以使用检索到的 videoUrl 显示视频

Intent intent = getIntent();
String videoUrl = intent.getStringExtra("VIDEO_URL");
