二：实现步骤：

1.在项目build.gradle里面添加包。

compile 'com.baoyz.swipemenulistview:library:1.3.0'

2.xml布局文件、

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <com.baoyz.swipemenulistview.SwipeMenuListView        android:id="@+id/listView"        android:layout_width="match_parent"        android:layout_height="match_parent" /></LinearLayout>

3.activity的实现，都写好了注释，相信也不难看懂，所以就不用解释了、

package com.example.administrator.myapplication;import android.content.Context;import android.graphics.Color;import android.graphics.drawable.ColorDrawable;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.widget.ArrayAdapter;import android.widget.Toast;import com.baoyz.swipemenulistview.SwipeMenu;import com.baoyz.swipemenulistview.SwipeMenuCreator;import com.baoyz.swipemenulistview.SwipeMenuItem;import com.baoyz.swipemenulistview.SwipeMenuListView;public class MainActivity extends AppCompatActivity {    private Context context;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        context = this;        /**         * 创建SwipeMenuCreator         */        SwipeMenuCreator creator = new SwipeMenuCreator() {            @Override            public void create(SwipeMenu menu) {                SwipeMenuItem openItem = new SwipeMenuItem(context);                openItem.setBackground(new ColorDrawable(Color.BLACK));                openItem.setWidth(dp2px(90));                openItem.setTitle("置顶");                openItem.setTitleSize(20);                openItem.setTitleColor(Color.WHITE);                menu.addMenuItem(openItem);                SwipeMenuItem deleteItem = new SwipeMenuItem(context);                deleteItem.setBackground(new ColorDrawable(Color.RED));                deleteItem.setWidth(dp2px(90));                deleteItem.setTitle("删除");                deleteItem.setTitleSize(20);                deleteItem.setTitleColor(Color.WHITE);                menu.addMenuItem(deleteItem);//                //可以加入图片//                SwipeMenuItem deleteItem1 = new SwipeMenuItem(context);//                deleteItem1.setBackground(new ColorDrawable(Color.LTGRAY));//                deleteItem1.setWidth(dp2px(90));//                deleteItem1.setIcon(android.R.drawable.ic_delete);//                menu.addMenuItem(deleteItem1);            }        };        /**         * 实例化         */        SwipeMenuListView listView = (SwipeMenuListView) findViewById(R.id.listView);        listView.setMenuCreator(creator);        /**         * 监听事件         */        listView.setOnMenuItemClickListener(new SwipeMenuListView.OnMenuItemClickListener() {            @Override            public boolean onMenuItemClick(int position, SwipeMenu menu, int index) {                //index的值就是在SwipeMenu依次添加SwipeMenuItem顺序值，类似数组的下标。                //从0开始，依次是：0、1、2、3...                switch (index) {                    case 0:                        Toast.makeText(context, "置顶:" + position, Toast.LENGTH_SHORT).show();                        break;                    case 1:                        Toast.makeText(context, "删除:" + position, Toast.LENGTH_SHORT).show();                        break;                }                // false : 当用户触发其他地方的屏幕时候，自动收起菜单。                // true : 不改变已经打开菜单的样式，保持原样不收起。                return false;            }        });        // 监测用户在ListView的SwipeMenu侧滑事件。        listView.setOnSwipeListener(new SwipeMenuListView.OnSwipeListener() {            @Override            public void onSwipeStart(int pos) {                Log.d("位置:" + pos, "开始侧滑...");            }            @Override            public void onSwipeEnd(int pos) {                Log.d("位置:" + pos, "侧滑结束.");            }        });        /**         * 添加一点死数据         */        String[] data = new String[15];        for (int i = 0; i < data.length; i++) {            data[i] = "消息:" + i;        }        /**         * 绑定adapter         */        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data);        listView.setAdapter(adapter);    }    public int dp2px(float dipValue) {        final float scale = this.getResources().getDisplayMetrics().density;        return (int) (dipValue * scale + 0.5f);    }}
