Question

我在这里遇到了问题。最近我正在开展一个像火种这样的项目，但这并不是那么进步。我做的更简单。

有一个可以滑过不同页面的滑动页面。你可以在每个页面中按压或不喜欢。

我想在这里做的是当他们点击“赞”按钮时，该页面将会消失并自动转到下一页。

我创建了带有喜欢和不喜欢按钮的幻灯片页面，但现在问题是

如何点击类似按钮，该页面将消失，它将自动转到下一页。

我会在下方附上我的寻呼机适配器，希望有人可以帮助我。如果您需要更多信息，请告诉我。非常感谢您提前。

Answer 1

试试这个

images.remove(postion); // This will remove that current page in ViewPager
notifyDataSetChanged(); // This will reload viewpager

使用layout.swipe从页面适配器中删除特定位置页面
