问题描述
我需要能够以编程方式消除RecyclerView
中的某个项目,而无需用户实际刷卡(相反,我想让他们点击卡中的按钮时消除该项目).我见过的许多图书馆似乎只支持实际的刷卡操作.
I need to be able to programmatically dismiss an item inside a RecyclerView
without the user actually swiping (instead I want to dismiss the item when they tap a button in the card). A lot of libraries I've seen only seem to support actual swipes.
我尝试使用现有的库,只是通过以编程方式自己创建滑动来模拟MotionEvent
,但这会干扰另一个水平滑动的侦听器,因此我想知道如何进一步实现此理想RecyclerView
,但是如果有人知道如何使用ListView
,我可以尝试改编.
I've tried using an existing library and just simulate a MotionEvent
by creating a swipe on my own programmatically, but this interferes with another horizontal-swipe listener, so I'm wondering how else this could be done, ideally for a RecyclerView
but if anyone knows how to for a ListView
instead I can try to adapt that.
我已经查看了此库以及其他库以获取灵感,但是我可以而是要弄清楚如何以编程方式触发滑动.
I've looked at this library as well as others for inspiration but I can't figure out how to trigger the swipes programmatically instead.
推荐答案
在自定义适配器中使用ListView
或RecyclerView
,并在从数据列表中删除项目后调用notifyDataSetChanged
:
Use a ListView
or RecyclerView
with custom adapter, and call notifyDataSetChanged
after removing an item from the datalist:
private void removeListItem(View rowView, final int position) {
Animation anim = AnimationUtils.loadAnimation(this,
android.R.anim.slide_out_right);
anim.setDuration(500);
rowView.startAnimation(anim);
new Handler().postDelayed(new Runnable() {
public void run() {
values.remove(position); //Remove the current content from the array
adapter.notifyDataSetChanged(); //Refresh list
}
}, anim.getDuration());
}
