標題：Android中SwipeMenuListView的使用

步驟：

            1.在佈局檔案中初始化做SwipeMenuListView

             2.在建立SwipeMenuCreator物件

            3.建立SwipeMenuItem，設定背景、寬度、圖示

            4.將SwipeMenuItem新增到SwipeMenu中。

            5.將SwipeMenuCreator，設定到SwipeMenuListView上

            6.為listView設定setOnMenuItemClickListener事件監聽器  回撥onItemClick()

程式碼:

     1.在佈局中新增;

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="${relativePackage}.${activityClass}" >


    <com.baoyz.swipemenulistview.SwipeMenuListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />


</RelativeLayout>

   2.在Activity中重寫：

   

 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：
