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

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 。请注意，我选项卡中有list。如何实现这一目标？这是我到目前为止所尝试过的。

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);
    }
    }

    } 

类列表名称。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;
  }

  } 

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;
}
}

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];
}

//该方法返回选项卡 Strip 的选项卡数量

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

Answer 1

在 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);
                }
            });

    }
}
