我正在使用Firebase UI FirebaseRecyclerAdapter填充RecyclerView。我设法从项目 View (标题)的组件中获取了单击事件,但没有从项目 View 中的任何地方获取到这,这是我所需要的。我跟随谷歌样本。
在我的 Activity 中:
private void setRecyclerView() {
recyclerView = (RecyclerView) findViewById(R.id.recycler_view_gigs);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
mAdapter = new FirebaseRecyclerAdapter<Gig, GigViewHolder>(Gig.class,
R.layout.list_item_card,
GigViewHolder.class,
reference) {
@Override
protected void populateViewHolder(final GigViewHolder viewGig, Gig model, final int position) {
viewGig.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i(Utils.TAG, "onItemClickGeneral: position " + position);
// this doesn't work
}
});
viewGig.bindToGig(model, new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i(Utils.TAG, "onItemClickTitle: position " + position);
// this works
}
});
}
};
recyclerView.setAdapter(mAdapter);
}
和我的ViewHolderClass:
public class GigViewHolder extends RecyclerView.ViewHolder {
ImageView ivIconArtist;
TextView tvArtist;
TextView tvVenue;
TextView tvDate;
public GigViewHolder(View view) {
super(view);
ivIconArtist = (ImageView) view.findViewById(R.id.iv_list_item_icon_artist);
tvArtist = (TextView) view.findViewById(R.id.tv_list_item_artist);
tvVenue = (TextView) view.findViewById(R.id.tv_list_item_venue);
tvDate = (TextView) view.findViewById(R.id.tv_list_item_date);
}
public void bindToGig(Gig gig, View.OnClickListener clickListener) {
tvArtist.setText(gig.getArtist());
tvVenue.setText(gig.getVenue());
tvDate.setText(gig.getDate());
tvArtist.setOnClickListener(clickListener);
}
}
我尝试了其他答案中建议的自定义onclicklistener +界面,也没有运气。
最佳答案
在FirebaseRecyclerViewAdapter中为整个行/项目实现单击和长按监听器。
我是这样做的。
IMPLEMENTATION
我的FirebaseViewHolder
类。
public class FirebaseViewHolder extends RecyclerView.ViewHolder {
public ImageView mImageView;
public TextView mPostTitle;
public TextView mPostDesc;
public FirebaseViewHolder(View itemView) {
super(itemView);
mImageView = (ImageView) itemView.findViewById(R.id.image_recyclerview);
mPostTitle = (TextView) itemView.findViewById(R.id.tv_title_recyclerview_item);
mPostDesc = (TextView) itemView.findViewById(R.id.tv_desc_recyclerview_item);
//listener set on ENTIRE ROW, you may set on individual components within a row.
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mClickListener.onItemClick(v, getAdapterPosition());
}
});
itemView.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
mClickListener.onItemLongClick(v, getAdapterPosition());
return true;
}
});
}
private FirebaseViewHolder.ClickListener mClickListener;
//Interface to send callbacks...
public interface ClickListener{
public void onItemClick(View view, int position);
public void onItemLongClick(View view, int position);
}
public void setOnClickListener(FirebaseViewHolder.ClickListener clickListener){
mClickListener = clickListener;
}
}
创建
FirebaseRecyclerAdapter
。FirebaseRecyclerAdapter<Post, FirebaseViewHolder> adapter = new FirebaseRecyclerAdapter<Post, FirebaseViewHolder>(
Post.class,
R.layout.recyclerview_list_item,
FirebaseViewHolder.class,
databaseReference
) {
@Override
protected void populateViewHolder(FirebaseViewHolder viewHolder, Post model, int position) {
Picasso.with(getActivity())
.load(model.image_url)
.into(viewHolder.mImageView);
Log.v(TAG, model.image_url);
//viewHolder.mImageView.setImageResource(R.mipmap.ic_launcher);
viewHolder.mPostTitle.setText(model.title);
viewHolder.mPostDesc.setText(model.desc);
}
@Override
public FirebaseViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
FirebaseViewHolder viewHolder = super.onCreateViewHolder(parent, viewType);
viewHolder.setOnClickListener(new FirebaseViewHolder.ClickListener() {
@Override
public void onItemClick(View view, int position) {
Toast.makeText(getActivity(), "Item clicked at " + position, Toast.LENGTH_SHORT).show();
}
@Override
public void onItemLongClick(View view, int position) {
Toast.makeText(getActivity(), "Item long clicked at " + position, Toast.LENGTH_SHORT).show();
}
});
return viewHolder;
}
};
