Add swipe right to delete ListView item

Question

I have a ListView that uses a custom adaper (that extends BaseAdapter). How do I add the swipe to delete gesture?

I want use the same functionality the gmail application uses.

Solution 1

The easiest way to do this is to move your ListView over to a RecyclerView and use a GridLayoutManager with a single column. It will look the same, but allows you to swipe to dismiss using the ItemTouchHelper.

     recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
     recyclerView.setLayoutManager(new GridLayoutManager(getActivity(), 1));

     recyclerView.setAdapter(adapter);


    ItemTouchHelper itemTouchHelper = new ItemTouchHelper(new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
        @Override
        public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
            // Remove item from backing list here
            adapter.notifyDataSetChanged();
        }
    });

    itemTouchHelper.attachToRecyclerView(recyclerView);

Solution 2

You can use the lib ::

SwipeMenuListView

Solution 3

Accepted answer translated to Kotlin:

val itemTouchHelper =  ItemTouchHelper(object: ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT or ItemTouchHelper.RIGHT) {
    override fun onMove(
        recyclerView: RecyclerView,
        viewHolder: RecyclerView.ViewHolder,
        target: RecyclerView.ViewHolder
    ): Boolean {
        TODO("Not yet implemented")
    }

    override fun onSwiped(viewHolder: RecyclerView.ViewHolder, direction: Int) {
            todoListAdapter.notifyDataSetChanged()
    }

})
this.runOnUiThread {
    itemTouchHelper.attachToRecyclerView(recyclerView)
}

Yes, you will have to change the ListView to a RecyclerView, change the adapter base class type and then create one or more Handlers for the data.

I have do it, but now i have scroll in recycleview, i don't want scroll i have already scrollview is possible remove scroll?

[Fra87]

I have solved problem of scroll, my Adapter is RecyclerView.Adapter, if i want method that return item from position How i do?

[Fra87]

i want to create my custom method delete in RecyclerView.Adapter but i have a dubt, after i have delete item from ArrayList then i call notifyDataSetChanged() or i call notifyItemRemoved() ?

[Gary Bak]

Removed is probably the better choice, then the adapter knows which positions it has to redraw. The notifyDataSetChanged will force it to redraw whatever is on the screen.

[Fra87]

Last question: If i want add listner on item how i can?

[Fra87]

From adapter is possible call onCreate activity?

Shall also implement public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {return false;} Upvoted!

This is an answer for flutter. However the question targets native android
