java - RecyclerView 列表和下一个 Activity Android 的 Intent

Question

我使用 RecyclerView 创建了一个列表，我希望如果用户触摸该列表中的某个项目，它会将用户重定向到另一个 activity。注意我在 tab 中有 list。如何做到这一点？到目前为止，这是我尝试过的方法。

1. 类列表适配器

公共(public)类 ListAdapter 扩展 RecyclerView.Adapter 实现 View.OnClickListener{

List<ListName> mItems;
public ListAdapter(FragmentActivity c) {
    super();
    mItems = new ArrayList<ListName>();

    ListName nature = new ListName();
    nature.setName("Jose Mourinho");
    nature.setDes("Chelsea Football Club");
    mItems.add(nature);

    nature = new ListName();
    nature.setName("Louis van Gaal");
    nature.setDes("Manchester United");
    mItems.add(nature);

    nature = new ListName();
    nature.setName("Arsene Wenger");
    nature.setDes("Arsenal");
    mItems.add(nature);

    nature = new ListName();
    nature.setName("Manuel Pellegrini");
    nature.setDes("Manchester City");
    mItems.add(nature);

    nature = new ListName();
    nature.setName("Brendan Rodgers");
    nature.setDes("Liverpool CF");
    mItems.add(nature);
    }
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View v = LayoutInflater.from(viewGroup.getContext())
            .inflate(R.layout.recyler_view_list, viewGroup, false);
    ViewHolder viewHolder = new ViewHolder(v);
    return viewHolder;
    }
    @Override
    public void onBindViewHolder(ViewHolder viewHolder, int i) {
    ListName nature = mItems.get(i);
    viewHolder.tvName.setText(nature.getName());
    viewHolder.tvDes.setText(nature.getDes());
    }
    @Override
    public int getItemCount() {

    return mItems.size();
    }

    @Override
    public void onClick(View v) {

    }

    class ViewHolder extends RecyclerView.ViewHolder{

    public TextView tvName;
    public TextView tvDes;
    public ViewHolder(View itemView) {
        super(itemView);
        tvName = (TextView)itemView.findViewById(R.id.txtTitle);
        tvDes = (TextView)itemView.findViewById(R.id.txtSubTitle);
    }
    }

    } 

1. 类 ListName 。该类用于设置和获取名称和描述

     public class ListName {
       private String mName;
       private String mDes;
   
      public String getName() {
      return mName;
    }
      public void setName(String name) {
   this.mName = name;
     }
      public String getDes() {
       return mDes;
     }
      public void setDes(String des) {
       this.mDes = des;
     }
   
     } 
   

2. Tab1 类。这是 Tab1 的 fragment 类。

    public class Tab1 extends Fragment {
   
    RecyclerView mRecyclerView;
    RecyclerView.LayoutManager mLayoutManager;
    RecyclerView.Adapter mAdapter;
   
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                        Bundle savedInstanceState) {
       final View view = inflater.inflate(R.layout.tab_1, container,      false);
   final FragmentActivity c = getActivity();
   final RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
   LinearLayoutManager layoutManager = new LinearLayoutManager(c);
   recyclerView.setLayoutManager(layoutManager);
   
   new Thread(new Runnable() {
       @Override
       public void run() {
           final ListAdapter adapter = new ListAdapter(c);
           c.runOnUiThread(new Runnable() {
               @Override
               public void run() {
                   recyclerView.setAdapter(adapter);
               }
           });
       }
   }).start();
   
   return view;
   }
   }
   

3. 类 ViewPagerAdapter 。此类是选项卡的适配器

    public class ViewPagerAdapter extends FragmentStatePagerAdapter {
   
    CharSequence Titles[]; 
    int NumbOfTabs; 
   
   
   public ViewPagerAdapter(FragmentManager fm, CharSequence mTitles[], int mNumbOfTabsumb) {
   super(fm);
   
   this.Titles = mTitles;
   this.NumbOfTabs = mNumbOfTabsumb;
   
    }
   
   @Override
   public Fragment getItem(int position) {
   
   if (position == 0) // if the position is 0 we are returning the First tab
   {
       Tab1 tab1 = new Tab1();
       return tab1;
   } else             // As we are having 2 tabs if the position is now 0 it must be 1 so we are returning second tab
   {
       Tab2 tab2 = new Tab2();
       return tab2;
   }
   
   }
   
   @Override
   public CharSequence getPageTitle(int position) {
      return Titles[position];
   }
   

   //此方法返回标签条的标签数

   @Override
   public int getCount() {
     return NumbOfTabs;
   }
   }
   

Answer 1

在您的 Viewholder 中的 itemView 上放置一个 setOnClickListener 并编写代码以转到另一个 Activity ( Intent )

class ViewHolder extends RecyclerView.ViewHolder
{

public TextView tvName;
public TextView tvDes;

    public ViewHolder(View itemView) 
    {
        super(itemView);
        tvName = (TextView)itemView.findViewById(R.id.txtTitle);
        tvDes = (TextView)itemView.findViewById(R.id.txtSubTitle);

        itemView..setOnClickListener(new View.OnClickListener()
            {
                @Override
                public void onClick(View v)
                {
                     Intent intent = new Intent(getActivity().getApplicationContext(), ActivityName.class);
                     startActivity(intent); //or startActivityForResult(REQUEST, intent);
                }
            });

    }
}
