我试图构建 android 新的收件箱样式 ListView ，如图所示左右滑动，我尝试了 47deg swipelistview但它不是那么稳定，还有其他可用的库吗？!

目前已尝试 47 度

 public class MainActivity extends Activity {

        Listview pullToRefreshListView;
        SwipeListView swipelistview;
        ItemAdapter adapter;
        List<ItemRow> itemData;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            pullToRefreshListView = (ListView) findViewById(R.id.example_swipe_lv_list);
            swipelistview = pullToRefreshListView.getRefreshableView();
            itemData = new ArrayList<ItemRow>();
            adapter = new ItemAdapter(this, R.layout.custom_row, itemData);

            swipelistview.setSwipeListViewListener(new BaseSwipeListViewListener() {
                @Override
                public void onOpened(int position, boolean toRight) {
                    if (toRight) {
                        adapter.remove(position);
                        Toast.makeText(MainActivity.this, "Open to dismiss",
                                Toast.LENGTH_SHORT).show();
                    } // swipelistview.dismiss(position);
                    else {
                        Toast.makeText(MainActivity.this, "Open to edit",
                                Toast.LENGTH_SHORT).show();
                    }
                }

                    if (right) {
                        // adapter.onRight();
                        swipelistview.getChildAt(position).findViewById(R.id.back)
                                .setBackgroundColor(Color.GREEN);

                                .setBackgroundColor(Color.RED);
                        swipelistview.getChildAt(position)
                                .findViewById(R.id.imageViewLeft)
                                .setVisibility(View.GONE);
                        swipelistview.getChildAt(position)

                    // swipelistview.openAnimate(position); //when you touch front
                    // view it will open

                }

                @Override

                    Log.d("swipe", String.format("onClickBackView %d", position));

                    // swipelistview.closeAnimate(position);//when you touch back
                    // view it will close
                }

                @Override
                public void onDismiss(int[] reverseSortedPositions) {

                }

            });

            // These are the swipe listview settings. you can change these
            // setting as your requirement
            swipelistview.setSwipeMode(SwipeListView.SWIPE_MODE_BOTH); // there are
                                                                        // five

                                                                                    // four

                                                                                    // actions
            swipelistview.setSwipeActionLeft(SwipeListView.SWIPE_ACTION_REVEAL);
            swipelistview.setOffsetRight(convertDpToPixel(0f)); // left side
                                                                // offset
            swipelistview.setOffsetLeft(convertDpToPixel(0f)); // right side
                                                                // offset
            swipelistview.setAnimationTime(60); // Animation time
            swipelistview.setSwipeOpenOnLongPress(false); // enable or disable
                                                            // SwipeOpenOnLongPress
            swipelistview.setSwipeCloseAllItemsWhenMoveList(true);
            swipelistview.setAdapter(adapter);

            for (int i = 0; i < 10; i++) {
                itemData.add(new ItemRow("Swipe Item" + i, getResources()
                        .getDrawable(R.drawable.ic_launcher)));

            }

            adapter.notifyDataSetChanged();
        }
 public int convertDpToPixel(float dp) {
    DisplayMetrics metrics = getResources().getDisplayMetrics();
    float px = dp * (metrics.densityDpi / 160f);
    return (int) px;
}
    }

适配器类

public class ItemAdapter extends ArrayAdapter<ItemRow> {

    List<ItemRow> data;
    Context context;
    int layoutResID;

    public ItemAdapter(Context context, int layoutResourceId, List<ItemRow> data) {
        super(context, layoutResourceId, data);

        this.data = data;
        this.context = context;
        this.layoutResID = layoutResourceId;

        // TODO Auto-generated constructor stub
    }

    NewsHolder holder = null;
    View row = null;

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        row = convertView;
        holder = null;

        if (row == null) {
            LayoutInflater inflater = ((Activity) context).getLayoutInflater();
            row = inflater.inflate(layoutResID, parent, false);

            holder = new NewsHolder();

            holder.itemName = (TextView) row
                    .findViewById(R.id.example_itemname);
            holder.icon = (ImageView) row.findViewById(R.id.example_image);
            holder.imageViewRight = (ImageView) row
                    .findViewById(R.id.imageViewRight);
            holder.imageViewLeft = (ImageView) row
                    .findViewById(R.id.imageViewLeft);

            row.setTag(holder);
        } else {
            holder = (NewsHolder) row.getTag();
        }

        ItemRow itemdata = data.get(position);
        holder.itemName.setText(itemdata.getItemName());
        holder.icon.setImageDrawable(itemdata.getIcon());

        return row;

    }
    public void remove(int pos){
        data.remove(pos);

    }

    public void onLeft() {

        holder.imageViewLeft.setVisibility(View.VISIBLE);
        holder.imageViewRight.setVisibility(View.GONE);
    }

    public void onRight() {
        holder.imageViewRight.setVisibility(View.VISIBLE);
        holder.imageViewLeft.setVisibility(View.GONE);
    }

    static class NewsHolder {

        TextView itemName;
        ImageView icon;
        ImageView imageViewLeft, imageViewRight;

        RelativeLayout mRelativeLayout;
    }

最佳答案

您可以简单地支持对列表项 onTouch 的“滑动”手势，而不是使用自定义 ListView，如下所示:

private static final int DEFAULT_THRESHOLD = 128;

row.setOnTouchListener(new View.OnTouchListener() {

    int initialX = 0;
    final float slop = ViewConfiguration.get(context).getScaledTouchSlop();

    public boolean onTouch(final View view, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            initialX = (int) event.getX();
            view.setPadding(0, 0, 0, 0);
        } else if (event.getAction() == MotionEvent.ACTION_MOVE) {
            int currentX = (int) event.getX();
            int offset = currentX - initialX;
            if (Math.abs(offset) > slop) {
                view.setPadding(offset, 0, 0, 0);

                if (offset > DEFAULT_THRESHOLD) {
                    // TODO :: Do Right to Left action! And do nothing on action_up.
                } else if (offset < -DEFAULT_THRESHOLD) {
                    // TODO :: Do Left to Right action! And do nothing on action_up.
                }
            }
        } else if (event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL) {
            // Animate back if no action was performed.
            ValueAnimator animator = ValueAnimator.ofInt(view.getPaddingLeft(), 0);
            animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
                @Override
                public void onAnimationUpdate(ValueAnimator valueAnimator) {
                    view.setPadding((Integer) valueAnimator.getAnimatedValue(), 0, 0, 0);
                }
            });
            animator.setDuration(150);
            animator.start();
        }
};

如果没有执行任何操作，我也会使用反向动画。

此解决方案是轻量级的，因此您不会遇到任何滞后。
