我是SwipeListView库的新手，轻扫了列表项之一后，此功能的工作方式如下：
该应用程序正在运行，但是视图被弄乱了，使得隐藏的内容（即在刷列表项之后看到的内容）被覆盖在每个列表项的顶部。在下面的图片之后，我粘贴了片段代码。
我怎样才能解决这个问题？
没有SwipeListView：
使用SwipeListView：

最佳答案
我现在有同样的问题。可能是因为正面布局的背景是透明的。该库不是隐藏代码，而是具有可见的背景。我通过将我的“后”视图隐藏在getView中，然后在滑动时使其可见来克服了这一问题。
mTourneyList.setSwipeListViewListener(new BaseSwipeListViewListener() {
@Override
public void onOpened(int position, boolean toRight) {
LinearLayout li = (LinearLayout) mTourneyList.getChildAt(position - mTourneyList.getFirstVisiblePosition()).findViewById(R.id.back);
li.setVisibility(View.VISIBLE);
}
或者您可以为前视图设置一些背景。
编辑：似乎“位置”参数未计算屏幕上的行，因此我稍稍更改了代码，并从“位置”中减去了第一个可见位置。
