Programmatically “swipe-to-dismiss” an item in a ListView/RecyclerView?

问题

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.

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.

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.

回答1:

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());
}

Use one of the libraries that offer the swipe to dissmis funcionality ad extract the animation part, if im not mistaken its at the action_up at the onTouch(). Then call it from your onClick of the button.
