android - 如何用新 View 滑动 ListView 会像android中的删除按钮一样出现？

Question

我已经有了一个带有 simpleCursorAdapter 的 ListView ，并显示来自 SD 卡的所有视频的缩略图..

现在我想进一步扩展我的 ListView ，我想以编程方式添加带有代码的滑动 ListView ，而不使用任何已经给出的 SwipeLibrary，我想使用滑动创建我自己的一组代码

我想创建类似这些的东西 http://www.youtube.com/watch?v=E0352OH488M

我想在不使用其他程序员库的情况下创建自己的代码集..

这是我的代码

public class FRAGThisWeek extends ListFragment {

    private static final String KEY_VIDEO_PATH = "AAA-1";
    private static final String KEY_VIDEO_TITLE = "AAA-2";
    private static final String KEY_VIDEO_ARTIST = "AAA-3";
    private static final String KEY_VIDEO_DURATION = "AAA-4";
    private static final String KEY_VIDEO_ID = "AAA-5";

    /* SOURCE URI FROM SDCARD */

    private static final Uri sourceUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
    private static final String[] projection = { MediaStore.Video.Media._ID,
            MediaStore.Video.Media.DATA, MediaStore.Video.Media.TITLE,
            MediaStore.Video.Media.DISPLAY_NAME, MediaStore.Video.Media.ARTIST,
            MediaStore.Video.Media.DURATION };
    private static final String orderBy = MediaStore.Video.Media.DATE_ADDED;

    /* THE DESIRED COLUMNS TO BE BOUND */
    private static final String[] from = { MediaStore.Video.Media.TITLE,
            MediaStore.Video.Media.ARTIST, MediaStore.Video.Media.DURATION };

    /* THE XML DEFINED VIEWS WHICH THE DATA WILL BE BOUND TO */
    private static final int[] to = { R.id.list_Title, R.id.list_Artist,
            R.id.list_Duration };

    private static Cursor videoCursor;
    private static int videoPathColumnIndex;
    private static int videoTitleColumnIndex;
    private static int videoArtistColumnIndex;
    private static int videoDurationColumnIndex;
    private static int videoIdColumnIndex;

    private static String videoPath;
    private static String videoTitle;
    private static String videoArtist;
    private static int videoDuration;
    private static int videoId;

    /* TO LUNCH PLAY.CLASS AND PUT MEDIA INFO INTO */
    private static Intent vIntent;

    /* MY CUSTOM ADAPTER */
    private static MyCustomSimpleCursorAdapter adapter;

    /* MY LISTVIEW */
    ListView lv;

    /* CUSTOM TYPE INFLATION IF NEED TO ADD MORE VIEW IN LISTVIEW XML LAYOUT */
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        return inflater.inflate(R.layout.frag_this_week, container, false);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        // CREATE CURSOR THAT WILL HOLD ALL VALUE
        videoCursor = getActivity().getContentResolver().query(sourceUri,
                projection, null, null, orderBy);

        // CREATE THE ADAPTER USING THE CURSOR POINTING TO THE
        // DESIRED DATA AS WELL AS THE LAYOUT INFORMATION
        adapter = new MyCustomSimpleCursorAdapter(getActivity(),
                R.layout.list_row_items, videoCursor, from, to);

        setListAdapter(adapter);

        // GET THE INSTANCE OF LISTVIEW for the swipeview purpose
        lv = getListView();
    }

    @Override
    /* ListView Listener */
    public void onListItemClick(ListView l, View v, int position, long id) {
        Log.d("clicked", "clicked");
    }

}

您为什么不看看这些库是如何制作的？

你基本上需要:

• 每行一个 onTouchListener 来检测滑动手势
• 一个对象动画师来移动你的观点。
• 用于显示您的 View 的自定义适配器。
