RecyclerView实现侧滑删除、置顶、滑动

1、首先在build.gradle里添加

compile 'com.github.mcxtzhang:SwipeDelMenuLayout:V1.2.1'

2、设置recyclerView的item布局

<?xml version="1.0" encoding="utf-8"?>

<com.mcxtzhang.swipemenulib.SwipeMenuLayout

    xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent"

    android:layout_height="100dp"

    android:clickable="true"

    android:paddingBottom="1dp"

    app:ios="false"

    app:leftSwipe="true"

    app:swipeEnable="true">

    <TextView

        android:id="@+id/content"

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:background="?android:attr/selectableItemBackground"

        android:gravity="center"

        android:text="项目中我是任意复杂的原Item布局" />

    <!-- 以下都是侧滑菜单的内容依序排列 -->

    <Button

        android:id="@+id/btnTop"

        android:layout_width="60dp"

        android:layout_height="match_parent"

        android:background="#d9dee4"

        android:text="置顶"

        android:textColor="@android:color/white" />

    <Button

        android:id="@+id/btnUnRead"

        android:layout_width="120dp"

        android:layout_height="match_parent"

        android:background="#ecd50a"

        android:clickable="true"

        android:text="标记未读"

        android:textColor="@android:color/white" />

    <Button

        android:id="@+id/btnDelete"

        android:layout_width="60dp"

        android:layout_height="match_parent"

        android:background="#d9dee4"

        android:text="删除"

        android:textColor="@android:color/white" />

</com.mcxtzhang.swipemenulib.SwipeMenuLayout>

3、Activity

public class RecyclerSlideActivity extends AppCompatActivity {

    private RecyclerView recyclerView;

    private RecyclerSlideAdapter adapter;

    private List<String> mDatas;

    private LinearLayoutManager mLayoutManager;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_recycler_slide);

        initData();

        recyclerView = (RecyclerView) findViewById(R.id.recycler);

        adapter = new RecyclerSlideAdapter(this, mDatas);

        adapter.setOnDelListener(new RecyclerSlideAdapter.onSlideListener() {

            @Override

            public void onDel(int position) {

                Toast.makeText(RecyclerSlideActivity.this, "删除:" + position, Toast.LENGTH_SHORT).show();

                mDatas.remove(position);

                adapter.notifyItemChanged(position);

            }

            @Override

            public void onTop(int position) {

                String s = mDatas.get(position);

                mDatas.remove(s);

                adapter.notifyItemInserted(0);

                mDatas.add(0, s);

                adapter.notifyItemRemoved(position + 1);

                if (mLayoutManager.findFirstVisibleItemPosition() == 0) {

                    recyclerView.scrollToPosition(0);

                }

            }

        });

        recyclerView.setAdapter(adapter);

        recyclerView.setLayoutManager(mLayoutManager = new LinearLayoutManager(this));

        recyclerView.setOnTouchListener(new View.OnTouchListener() {

            @Override

            public boolean onTouch(View view, MotionEvent motionEvent) {

                if (motionEvent.getAction() == MotionEvent.ACTION_UP) {

                    SwipeMenuLayout viewCache = SwipeMenuLayout.getViewCache();

                    if (null != viewCache) {

                        viewCache.smoothClose();

                    }

                }

                return false;

            }

        });

    }

    private void initData() {

        mDatas = new ArrayList<>();

        for (int i = 0; i < 40; i++) {

            mDatas.add("item" + i);

        }

    }

}

4、adapter

public class RecyclerSlideAdapter extends RecyclerView.Adapter<RecyclerSlideAdapter.Slide> {

    private Context context;

    private LayoutInflater mInflater;

    private List<String> mDatas;

    public RecyclerSlideAdapter(Context context, List<String> mDatas) {

        this.context = context;

        this.mDatas = mDatas;

        mInflater = LayoutInflater.from(context);

    }

    @Override

    public Slide onCreateViewHolder(ViewGroup parent, int viewType) {

        return new Slide(mInflater.inflate(R.layout.item_recycler, parent, false));

    }

    @Override

    public void onBindViewHolder(final Slide holder, final int position) {

        //这句话关掉IOS阻塞式交互效果，并依此打开左滑右滑

//        ((SwipeMenuLayout) holder.itemView).setIos(false).setLeftSwipe(position % 2 == 0 ? true : false);

//        holder.content.setText(mDatas.get(position));

        //验证长按

        holder.content.setOnLongClickListener(new View.OnLongClickListener() {

            @Override

            public boolean onLongClick(View view) {

                Toast.makeText(context, "longclig", Toast.LENGTH_SHORT).show();

                return false;

            }

        });

        holder.btnUnRead.setVisibility(position % 3 == 0 ? View.GONE : View.VISIBLE);

        holder.btnDelete.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                /**

                 * 如果删除时，不适用adapter.notifyItemRemoved(position),则删除没有动画效果

                 * 如果想让侧滑菜单同时关闭，需要同时调用(CstSwipeDelMenu)holder.itemView).quickClose();

                 */

                mOnSlideListener.onDel(holder.getAdapterPosition());

            }

        });

        //注意事项，设置item点击，不能对真个holder.itemView设置，只能对第一个TextView设置

        holder.content.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                Toast.makeText(context, "onClick:" + position, Toast.LENGTH_SHORT).show();

            }

        });

        //置顶

        holder.btnTop.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                if (null != mOnSlideListener) {

                    mOnSlideListener.onTop(holder.getAdapterPosition());

                }

            }

        });

    }

    @Override

    public int getItemCount() {

        return null != mDatas ? mDatas.size() : 0;

    }

    /**

     * 和Activity通信的接口

     */

    public interface onSlideListener {

        void onDel(int position);

        void onTop(int position);

    }

    private onSlideListener mOnSlideListener;

    public onSlideListener getmOnSlideListener() {

        return mOnSlideListener;

    }

    public void setOnDelListener(onSlideListener mOnDelListener) {

        this.mOnSlideListener = mOnDelListener;

    }

    public class Slide extends RecyclerView.ViewHolder {

        TextView content;

        Button btnDelete;

        Button btnUnRead;

        Button btnTop;

        public Slide(View itemView) {

            super(itemView);

            content = (TextView) itemView.findViewById(R.id.content);

            btnDelete = (Button) itemView.findViewById(R.id.btnDelete);

            btnUnRead = (Button) itemView.findViewById(R.id.btnUnRead);

            btnTop = (Button) itemView.findViewById(R.id.btnTop);

        }

    }

}

RecyclerView滑动Scroll

package com.bumptech.glide.integration.recyclerview;

import android.support.v7.widget.LinearLayoutManager;

import android.support.v7.widget.RecyclerView;

import android.widget.AbsListView;

import android.widget.ListView;

/**

 * Converts {@link android.support.v7.widget.RecyclerView.OnScrollListener} events to

 * {@link AbsListView} scroll events.

 *

 * <p>Requires that the the recycler view be using a {@link LinearLayoutManager} subclass.

 */

public final class RecyclerToListViewScrollListener extends RecyclerView.OnScrollListener {

  public static final int UNKNOWN_SCROLL_STATE = Integer.MIN_VALUE;

  private final AbsListView.OnScrollListener scrollListener;

  private int lastFirstVisible = -1;

  private int lastVisibleCount = -1;

  private int lastItemCount = -1;

  public RecyclerToListViewScrollListener(AbsListView.OnScrollListener scrollListener) {

    this.scrollListener = scrollListener;

  }

  @Override

  public void onScrollStateChanged(RecyclerView recyclerView, int newState) {

    int listViewState;

    switch (newState) {

      case RecyclerView.SCROLL_STATE_DRAGGING:

        listViewState = ListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL;

        break;

      case RecyclerView.SCROLL_STATE_IDLE:

        listViewState = ListView.OnScrollListener.SCROLL_STATE_IDLE;

        break;

      case RecyclerView.SCROLL_STATE_SETTLING:

        listViewState = ListView.OnScrollListener.SCROLL_STATE_FLING;

        break;

      default:

        listViewState = UNKNOWN_SCROLL_STATE;

    }

    scrollListener.onScrollStateChanged(null /*view*/, listViewState);

  }

  @Override

  public void onScrolled(RecyclerView recyclerView, int dx, int dy) {

    LinearLayoutManager layoutManager = (LinearLayoutManager) recyclerView.getLayoutManager();

    int firstVisible = layoutManager.findFirstVisibleItemPosition();

    int visibleCount = Math.abs(firstVisible - layoutManager.findLastVisibleItemPosition());

    int itemCount = recyclerView.getAdapter().getItemCount();

    if (firstVisible != lastFirstVisible || visibleCount != lastVisibleCount

        || itemCount != lastItemCount) {

      scrollListener.onScroll(null, firstVisible, visibleCount, itemCount);

      lastFirstVisible = firstVisible;

      lastVisibleCount = visibleCount;

      lastItemCount = itemCount;

    }

  }

}
