SwipeLayout的简单使用

SwipeLayout(https://github.com/daimajia/AndroidSwipeLayout)，顾名思义，Android平台上的滑动布局，是一个可以让我们很方便使用滑动的库，典型的应用就是侧滑删除与侧滑菜单。在android的开发中运用的场景也是很多。如图所示的效果。

本篇文章主要介绍它的基本用法，目的在于能让你快速上手使用。

 1.配置

在gradle中添加以下依赖

compile "com.daimajia.swipelayout:library:1.2.0@aar"

compile 'com.android.support:recyclerview-v7:25.3.1'

2.xml文件布局 //最外层的cardview可以自己替换

3.构建适配器（注意要继承 RecyclerSwipeAdapter ）

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

import com.daimajia.swipe.adapters.RecyclerSwipeAdapter;

import java.util.List;

public class MyRecyclerViewAdapter extends RecyclerSwipeAdapter {
    private Context context;
    private List list;

    public MyRecyclerViewAdapter(Context context,List list){
        this.context=context;
        this.list=list;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.note_item,parent,false);

        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(MyViewHolder viewHolder, final int position) {
        Note note = list.get(position);
        viewHolder.note_title.setText(note.getNote_title());
        viewHolder.note_content_abs.setText(note.getNote_content_abs());
        viewHolder.note_time.setText(note.getNote_time());
    }
    @Override
    public int getItemCount() {
        return list.size();
    }

    @Override
    public int getSwipeLayoutResourceId(int position) {
        return position;
    }

    class MyViewHolder extends RecyclerView.ViewHolder{

        CardView cardView;
        TextView note_title;
        TextView note_content_abs;
        TextView note_time;

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

            cardView = (CardView) itemView;
            note_title = (TextView) itemView.findViewById(R.id.note_item_title);
            note_content_abs = (TextView) itemView.findViewById(R.id.note_item_abs);
            note_time = (TextView) itemView.findViewById(R.id.note_item_time);
        }
    }
}

        switch (item.getItemId()){
            case R.id.toolbar_open:
                drawerLayout.openDrawer(Gravity.RIGHT);
                break;
            default:
                break;
        }
        return true;
    }
}

上面的Note是填充 RecyclerView的item。

4.最终效果实现侧滑菜单
