标题：Android中SwipeMenuListView的使用

步骤：

1.在布局文件中初始化做SwipeMenuListView

2.在创建SwipeMenuCreator对象

3.创建SwipeMenuItem，设置背景、宽度、图标

4.将SwipeMenuItem添加到SwipeMenu中。

5.将SwipeMenuCreator，设置到SwipeMenuListView上

6.为listView设置setOnMenuItemClickListener事件监听器  回调onItemClick()

代码:

1.在布局中添加;

2.在Activity中重写：

private SwipeMenuListView mListView;
    
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_list);
    
    
            mAppList = getPackageManager().getInstalledApplications(0);
    
    
            mListView = (SwipeMenuListView) findViewById(R.id.listView);
            mAdapter = new AppAdapter();
            mListView.setAdapter(mAdapter);
    
    
            // step 1. create a MenuCreator
            SwipeMenuCreator creator = new SwipeMenuCreator() {
    
    
                @Override
                public void create(SwipeMenu menu) {
                    // create "open" item
                    SwipeMenuItem openItem = new SwipeMenuItem(
                            getApplicationContext());
                    // set item background
                    openItem.setBackground(new ColorDrawable(Color.rgb(0xC9, 0xC9,
                            0xCE)));
                    // set item width
                    openItem.setWidth(dp2px(90));
                    // set item title
                    openItem.setTitle("Open");
                    // set item title fontsize
                    openItem.setTitleSize(18);
                    // set item title font color
                    openItem.setTitleColor(Color.WHITE);
                    // add to menu
                    menu.addMenuItem(openItem);
    
    
                    // create "delete" item
                    SwipeMenuItem deleteItem = new SwipeMenuItem(
                            getApplicationContext());
                    // set item background
                    deleteItem.setBackground(new ColorDrawable(Color.rgb(0xF9,
                            0x3F, 0x25)));
                    // set item width
                    deleteItem.setWidth(dp2px(90));
                    // set a icon
                    deleteItem.setIcon(R.drawable.ic_delete);
                    // add to menu
                    menu.addMenuItem(deleteItem);
                }
            };
            // set creator
            mListView.setMenuCreator(creator);
    
    
            // step 2. listener item click event
            mListView.setOnMenuItemClickListener(new SwipeMenuListView.OnMenuItemClickListener() {
                @Override
                public boolean onMenuItemClick(int position, SwipeMenu menu, int index) {
                    ApplicationInfo item = mAppList.get(position);
                    switch (index) {
                        case 0:
                            // open
                            open(item);
                            break;
                        case 1:
                            // delete
    // delete(item);
                            mAppList.remove(position);
                            mAdapter.notifyDataSetChanged();
                            break;
                    }
                    return false;
                }
            });

效果：
