推荐答案
您不应在 ViewHolder 中设置点击侦听器，因为您将无法访问位置或任何内容.请使用 ClickListenerHelper 如示例.
You should not set click listeners within the ViewHolder as you would not be able to access position or anything. Please use the ClickListenerHelper as shown in the sample.
//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 时向视图添加一个 listener.并为您返回项目、位置及其视图.
Basically, this will add a listener to the view when the ViewHolder is created. And returns the item, the position, and its view for you.
