Remember a SwipeMenuListView side sliding deletion disorder bug in Android development

There are many solutions on the Internet for sliding deletion, such as rewriting Listview to monitor sliding. Today we will talk about the next SwipeListView. This is an encapsulated component that was open sourced by a friend on the Internet. It can be applied to a variety of situations. Project address: https://github.com/baoyongzhang/SwipeMenuListView, I also adopted the borrowing principle and used it directly.

But when debugging and running the sliding deletion of data, a problem occurred. The deletion position was wrong. The first data deleted was deleted, but the last one was deleted. So to find the problem, I first tried it with listview. After checking, there is no problem with the data, so it means that the position of the deleted control was calculated incorrectly during deletion. Here are two renderings first.

So what caused the problem? I looked at a previously submitted version (I remember that it was good to use before, indicating that it was a recently submitted problem), so I found a problem, that is, the getview method of the SwipeMenuAdapter class is smaller than before. There is one more judgment, added for caching. I tried to remove the judgment condition and ran it again. Okay, here is some code.

public View getView(int position, View convertView, ViewGroup parent) { 
SwipeMenuLayout layout = null; 
// if (convertView == null) { 
View contentView = mAdapter.getView(position, convertView, parent); 
SwipeMenu menu = new SwipeMenu(mContext); 
menu.setViewType(getItemViewType(position)); 
createMenu(menu); 
SwipeMenuView menuView = new SwipeMenuView(menu, 
(SwipeMenuListView) parent); 
menuView.setOnSwipeItemClickListener(this); 
SwipeMenuListView listView = (SwipeMenuListView) parent; 
layout = new SwipeMenuLayout(contentView, menuView, 
listView.getCloseInterpolator(), 
listView.getOpenInterpolator()); 
layout.setPosition(position); 
// } else { 
// layout = (SwipeMenuLayout) convertView; 
// layout.closeMenu(); 
// layout.setPosition(position); 
//// View view = mAdapter.getView(position, layout.getContentView(), 
//// parent); 
// } 
if (mAdapter instanceof BaseSwipListAdapter) { 
boolean swipEnable = (((BaseSwipListAdapter) mAdapter).getSwipEnableByPosition(position)); 
layout.setSwipEnable(swipEnable); 
} 
return layout; 
}
