android - FastAdapter 位置

Question

我正在使用 mike penz 的快速 adapter，我试图从 adapter 中删除项目。就像当我按下接受按钮然后该项目必须从列表中删除但是要删除我需要在其中传递位置变量但我无法从 adapter.

MainActivity.class

Answer 1

您不应在 ViewHolder 中设置点击监听器，因为您将无法访问位置或任何内容。请使用 sample 中所示的 ClickListenerHelper。

//init the ClickListenerHelper which simplifies custom click listeners on views of the Adapter
mClickListenerHelper = new ClickListenerHelper<>(fastItemAdapter);

fastItemAdapter.withOnCreateViewHolderListener(new FastAdapter.OnCreateViewHolderListener() {
    @Override
    public RecyclerView.ViewHolder onPreCreateViewHolder(ViewGroup parent, int viewType) {
        return fastItemAdapter.getTypeInstance(viewType).getViewHolder(parent);
    }

    @Override
    public RecyclerView.ViewHolder onPostCreateViewHolder(final RecyclerView.ViewHolder viewHolder) {
        mClickListenerHelper.listen(viewHolder, ((Doc_Appointment_Req_Adapter.Doc_App_req_Vh) viewHolder). accept, new ClickListenerHelper.OnClickListener<Doc_Appointment_Req_Adapter>() {
            @Override
            public void onClick(View v, int position, Doc_Appointment_Req_Adapter item) {
                ...
            }
        });
        return viewHolder;
    }
});

基本上，这会在创建 ViewHolder 时向 View 添加一个 listener。并为您返回项目、位置及其 View 。
