AndroidStudio类微信界面+RecycleView

1、修改后的tab01.xml

添加recycleview控件

        final boolean isExpanded = position == expandedPosition;
        holder.rlChild.setVisibility(isExpanded ? View.VISIBLE : View.GONE);
        holder.rlParent.setOnClickListener(new View.OnClickListener() {
            @Override

                    notifyItemChanged(expandedPosition);
                }
                expandedPosition = isExpanded ? -1 : holder.getAdapterPosition();
                mViewHolder = isExpanded ? null : holder;
                notifyItemChanged(holder.getAdapterPosition());
            }
        });
    }

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

    class expandviewholder extends RecyclerView.ViewHolder{
        RelativeLayout rlParent, rlChild;
        TextView tvTeam, tvTeamChild;
        public expandviewholder(View itemView) {
            super(itemView);
            rlParent = itemView.findViewById(R.id.rl_parent);
            rlChild = itemView.findViewById(R.id.rl_child);

            tvTeamChild = itemView.findViewById(R.id.tv_team_child);
        }
    }
}

3、adapter_wisp.java

package com.example.mywechart;

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

import androidx.recyclerview.widget.RecyclerView;

import java.util.List;

public class adapter_swipe extends RecyclerView.Adapter<adapter_swipe.swipeviewholder> implements ItemTouchHelperListener{

    private List<String>list;
    private Context context;
    private View inflater;

    public adapter_swipe(Context context, List<String> list) {
        this.context=context;
        this.list=list;
    }

    @Override

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

    @Override
    public void onItemDismiss(int position) {
        if (position < 0 || position > getItemCount()) {
            return;
        }

        list.remove(position);
        notifyItemRemoved(position);

        // 解决 RecyclerView 删除 Item 导致位置错乱的问题
        if (position != list.size()) {
            notifyItemRangeChanged(position, list.size() - position);
        }
    }

    public class swipeviewholder extends RecyclerView.ViewHolder{
        TextView tvContent;

        public swipeviewholder(View itemView) {
            super(itemView);

        import androidx.recyclerview.widget.ItemTouchHelper;
        import androidx.recyclerview.widget.LinearLayoutManager;
        import androidx.recyclerview.widget.RecyclerView;

        import java.util.ArrayList;
        import java.util.List;


public class weixinFragment extends Fragment {



    private RecyclerView recyclerView;
    private List<String> mList = new ArrayList<>();
    private Context context;
    private adapter_swipe adapter;

    public weixinFragment() {
        // Required empty public constructor
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view= inflater.inflate(R.layout.tab01, container, false);

        recyclerView=view.findViewById(R.id.rcv_swipe);
        initData();
        initView();

        return view;
    }

    private void initData() {
        mList.add("Never Gonna Give You UP");
        mList.add("Scared To Be Lonely");
        mList.add("Once Upon a Time");
        mList.add("Ham");
        mList.add("How To Love");
        mList.add("In The Name Of Love");
        mList.add("Bloom");
        mList.add("Ghost");

        mList.add("Where Is You Love");
        mList.add("Changing");
        mList.add("Come and Get You Love");
        mList.add("Money Run Low");
        mList.add("Radioactive In The Dark");
        mList.add("Come Back To You");
        mList.add("The Heat");
        mList.add("There For You");
        mList.add("Here with You");
        mList.add("Wannabe");
        mList.add("Flowers");
        mList.add("Suck for You");
        mList.add("Take a Walk");
        mList.add("Shots");
        mList.add("Meant To Be");
        mList.add("Ferrari");
        mList.add("Hey Mamma");
        mList.add("Hands in the Fire");
    }

    private void initView(){
        context=this.getActivity();
        adapter=new adapter_swipe(context,mList);

        ItemTouchHelper.Callback callback = new SwipeItemTouchHelper(adapter);
        ItemTouchHelper touchHelper = new ItemTouchHelper(callback);
        touchHelper.attachToRecyclerView(recyclerView);

        LinearLayoutManager manager=new LinearLayoutManager(context);
        manager.setOrientation(LinearLayoutManager.VERTICAL);

        recyclerView.setAdapter(adapter);
        recyclerView.setLayoutManager(manager);
        recyclerView.setHasFixedSize(true);
    }


}

6、ItemTouchHelperListener

package com.example.mywechart;

public interface ItemTouchHelperListener {
    void onItemDismiss(int position);
}
