//I tried different approaches but none of them have worked out for me so far please help





//this is the adapter on which the upper recyclerview is based on


public class DessertAdapter extends RecyclerView.Adapter<DessertAdapter.DessertVh> {



    public static class DessertVh extends RecyclerView.ViewHolder{

        CardView cv;
        TextView personName;
        TextView personAge;
        ImageView personPhoto;


        DessertVh(View itemView){
            super(itemView);
            cv = (CardView)itemView.findViewById(R.id.cv);
            personName = (TextView)itemView.findViewById(R.id.person_name);

        return dvh;

    }

    @Override
    public void onBindViewHolder(DessertVh dessertVh, int i){
        dessertVh.personName.setText(persons.get(i).name);

Answer 1

尝试这样的事情：（在RecylcerView的OnItemClicklistener中）：

Intent intent = new Intent(Intent.ACTION_SEND); intent.putExtra(Intent.EXTRA_TEXT, persons.get(position); intent.setPackage("com.google.android.apps.youtube.app"); startActivity(intent);

我希望这有帮助！：d

Answer 2

您可以设置点击这样的每个项目。您需要在列表项中传递一些视频网址。然后你将用该网址启动youtube活动。

List<Dessert> persons;
Context context
DessertAdapter(Context context, List<Dessert> persons)
{
  this.persons = persons;
  this.context = context;
}

...

@Override
public void onBindViewHolder(DessertVh dessertVh, int i){
   ...

    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Uri url = Uri.parse("vnd.youtube://" + video_id); // get your url from list item or your code.
            Intent intent = new Intent(Intent.ACTION_VIEW, url);
            context.startActivity(intent);
        }
    });
    }

像

一样调用你的适配器

    DessertAdapter adapter = new DessertAdapter(AnimateToolbar.this, persons);
    rv.setAdapter(adapter);

如何使用recyclerview打开隐含意图，以便打开YouTube视频
