Android 无法获取项目位置以取消listitem

我正在我的应用程序中使用Roman Nurik的

SwipeListViewTouchListener

关闭列表项。 这就是我正在做的：

SwipeListViewTouchListener touchListener2 =
                new SwipeListViewTouchListener(
                    lv,
                    new SwipeListViewTouchListener.OnSwipeCallback() {
                       @Override
                      public void onSwipeLeft(ListView listView, int [] reverseSortedPositions) { 
                            Toast.makeText(MainActivity.this, "LEFT", Toast.LENGTH_SHORT).show(); 
                      }

                      @Override
                     public void onSwipeRight(ListView listView, int [] reverseSortedPositions) {

                        }
                 },
                 true, // example : left action = dismiss
                 true); // example : right action without dismiss animation

        lv.setOnTouchListener(touchListener2); 
        lv.setOnScrollListener(touchListener2.makeScrollListener());

现在，我的问题是如何从列表中删除已删除的项（类似于

customAdapter.remove(position);

并通知适配器，如

customAdapter.notifyDataSetChanged();

试试这个

public void onSwipeLeft(ListView listView, int[] reverseSortedPositions) {
    Toast.makeText(MainActivity.this, "LEFT", Toast.LENGTH_SHORT).show();
    if (reverseSortedPositions != null && reverseSortedPositions.length>0) {
        for (int i : reverseSortedPositions) {
            customAdapter.remove(i);
        }
        customAdapter.notifyDataSetChanged();
    }
}

试试这个

public void onSwipeLeft(ListView listView, int[] reverseSortedPositions) {
    Toast.makeText(MainActivity.this, "LEFT", Toast.LENGTH_SHORT).show();
    if (reverseSortedPositions != null && reverseSortedPositions.length>0) {
        for (int i : reverseSortedPositions) {
            customAdapter.remove(i);
        }
        customAdapter.notifyDataSetChanged();
    }
}

您回答了您的问题。请从适配器中删除该项，然后调用notifyDataSetChangedwhat's problem if you have adapter just do you want.@keshav但我无法获取toouchlistiner2中位置的值。是否从中获取数据db@Sparkplug您的customAdapter是什么？是扩展BaseApter还是ArrayAdapter？您回答yo您的问题。从适配器中删除该项并调用notifyDataSetChangedwhat's problem if you have adapter just do you want.@keshav但我无法获取toouchlistiner2中位置的值。您从中获取数据吗db@Sparkplug什么是您的customAdapter？是扩展BaseApter还是ArrayAdapter？谢谢，伙计。现在它可以工作了正如计划的那样。谢谢你，伙计。现在它正在按计划工作。
