如何在列表视图中滑动一个新的视图，就像android中的删除按钮一样？

Question

我已经有一个列表视图与simpleCursorAdapter，并显示缩略图所有的视频从SD卡..

现在我想扩展我的列表视图更多，我想添加卷帘列表视图的代码是以编程方式不使用任何已给出的SwipeLibrary，我想创建自己的代码集使用卷帘

我想创建像这些http://www.youtube.com/watch?v=E0352OH488M这样的东西

我想创建自己的代码集，而不使用其他程序员的库。

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");
    }

}

Answer 1

你为什么不看看这些库是如何制作的呢？

你基本上需要：

• a onTouchListener on each row以检测滑动手势
• an objectanimator以移动视图。
• 自定义适配器以显示视图。

Answer 2

这是我通过添加HorizontalScrollView实现的。整个列表视图项布局都在HorizontalScrollView中。在那之后，我为这个HorizontalScrollView实现了自己的OnTouchListener。在没有任何库的情况下运行良好。

最好尝试一下swipe来删除样式。它适合android系统。https://github.com/timroes/SwipeToDismissUndoList
