RecyclerViewを使ってアンドロイドでリストを作成するには？

Question

私はrecyclerViewを使用してリストを作成したいと思いますか？アンドロイドでそれを行う方法を教えてください。

public class MainActivity extends AppCompatActivity { 

     RecyclerView myRecyclerView; 

     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_main); 

      myRecyclerView = (RecyclerView)findViewById(R.id.my_recycler_view); 

      LinearLayoutManager layoutManager = new LinearLayoutManager(this); 
      myRecyclerView.setLayoutManager(layoutManager); 

      myRecyclerView.setAdapter(new FriendListAdapter()); 

     } 
    } 

Answer 1

XML：

<android.support.v7.widget.RecyclerView 
     android:id="@+id/rv_test" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:scrollbarStyle="outsideInset" 
     android:scrollbars="vertical" /> 

JAVAクラス

ArrayList<String>list_friend; 
    RecyclerView rv_test = (RecyclerView) view.findViewById(R.id.rv_test); 
    LinearLayoutManager mLinearLayoutManager = new LinearLayoutManager(YourActivity.this); 
    rv_test.setLayoutManager(mLinearLayoutManager); 
    rv_test.setHasFixedSize(true); 
    rv_test.setItemAnimator(new DefaultItemAnimator()); 

    //Set Adapter 

    FriendListAdapter mAdapter = new FriendListAdapter(list_friend); 
    rv_test.setAdapter(mAdapter); 

FriendListAdapter

public class FriendListAdapter extends RecyclerView.Adapter<FriendList.ViewWrapper> { 
     ArrayList<String>list_friend; 
     public FriendList(ArrayList<String>list_friend) { 
      this.list_friend=list_friend; 
     } 

     @Override 
     public ViewWrapper onCreateViewHolder(ViewGroup viewGroup, int i) { 
      // create a new view 
      @SuppressLint("InflateParams") View itemLayoutView = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_friend, null); 
      // create ViewHolder 
      return new ViewWrapper(itemLayoutView); 
     } 

     @Override 
     public void onBindViewHolder(final ViewWrapper viewWrapper, int position) { 
      viewWrapper.getName().setText(list_friend.get(viewWrapper.getAdapterPosition())); 
     } 

     @Override 
     public int getItemCount() { 
      return list_friend.size(); 
     } 

     class ViewWrapper extends RecyclerView.ViewHolder { 
      final View base; 
      TextView tv_name; 

      public ViewWrapper(View itemView) { 
       super(itemView); 
       base = itemView; 
      } 

      TextView getName() { 
       if (tv_name == null) { 
        tv_name = (TextView) base.findViewById(R.id.tv_name); 
       } 
       return (tv_name); 
      } 
     } 
    }

MyAdapterアダプタ=新しいMyAdapter（MainActivity.this、あなたのリスト） recyclerview.setA dapter（アダプター）;その後、

と

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.CustomViewHolder> implements View.OnClickListener { 

    ArrayList<String> arr; 
    Context mContext; 

    public MyAdapter(Context context, ArrayList<String> Arr,) { 
     this.arr = arr; 
     this.mContext = context; 

    } 

    @Override 
    public int getItemCount() { 
     // TODO Auto-generated method stub 
     return (null != arr ? arr.size() : 0); 
    } 

    @Override 
    public void onBindViewHolder(final CustomViewHolder arg0, final int position) { 


    } 


    @Override 
    public CustomViewHolder onCreateViewHolder(ViewGroup viewGroup, int arg1) { 
     View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_item, null); 
     RecyclerView.LayoutParams lp = new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
     view.setLayoutParams(lp); 


     CustomViewHolder viewHolder = new CustomViewHolder(view); 

     return viewHolder; 

    } 

    @Override 
    public void onClick(View v) { 



    } 

    public class CustomViewHolder extends RecyclerView.ViewHolder { 


     public CustomViewHolder(View rowView) { 
      super(rowView); 


     } 
    } 



}

XMLファイルアダプタクラスを作成します - 主な活動に

<android.support.v7.widget.RecyclerView 
     android:id="@+id/recycle_view" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     /> 

： - アダプタで

myTagRecyclerView = (RecyclerView) view.findViewById(R.id.cardList); 
    RecyclerView.LayoutManager mLayoutManager = newLinearLayoutManager(this); 
    myTagRecyclerView.setLayoutManager(mLayoutManager); 
    myTagRecyclerView.setItemAnimator(new DefaultItemAnimator()); 
MyTagRecyclerViewAdapter adapterTagItemList = new MyTagRecyclerViewAdapter(this, dataList); 
myTagRecyclerView.setAdapter(adapterTagItemList); 

： -

import android.content.Context; 
import android.support.v7.widget.RecyclerView; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.TextView;
