RecyclerView 是Android L版本中新添加的一个用来取代ListView的SDK，它的灵活性与可替代性比ListView更好。RecyclerView的强大这里就不说了。
RecyclerView
RecyclerView使用有点小小的不足，就是没有像ListView那样提供ClickListener和LongClickListener方法，需要我们手动去添加。这并不影响它的灵活性。
要实现RecyclerView的ClickListener和LongClickListener方法，我们可以用这种方式来实现：
在适配器adapter中定义接口，然后在onBindViewHolder中去为holder.itemView去设置相应的监听，最后回调我们设置的监听即可。
public class AikaifaAdapter extends RecyclerView.Adapter<AikaifaAdapter.AikaifaViewHolder> { private Context mConttext; private List<ShopCar.CarList> data; //定义接口
public interface OnItemClickListener { void onItemClick(View view, int position); void onItemLongClick(View view, int position);
} private OnItemClickListener mOnItemClickListener; public AikaifaAdapter(Context context, List<ShopCar.CarList> data) { this.mConttext = context; this.data = data;
} public void setOnItemClickListener(OnItemClickListener mOnItemClickListener) { this.mOnItemClickListener = mOnItemClickListener;
} @Override
public AikaifaAdapter.AikaifaViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view;
view = LayoutInflater.from(mConttext).inflate(R.layout.item_shopcart, parent, false); return new AikaifaAdapter.AikaifaViewHolder(view);
} @Override
public void onBindViewHolder(final AikaifaViewHolder holder, final int position) {
holder.tv.setText(data.get(position).getProductName()); if (mOnItemClickListener != null) {
holder.itemView.setOnClickListener(new View.OnClickListener() { @Override
public void onClick(View v) { int pos = holder.getLayoutPosition();
mOnItemClickListener.onItemClick(holder.itemView, position);
}
});
holder.itemView.setOnLongClickListener(new View.OnLongClickListener() { @Override
public boolean onLongClick(View v) { int pos = holder.getLayoutPosition();
mOnItemClickListener.onItemLongClick(holder.itemView, pos); return false;
}
});
}
} @Override
public int getItemCount() { int count = (data == null ? 0 : data.size()); return count;
} class AikaifaViewHolder extends RecyclerView.ViewHolder { private TextView tv; public AikaifaViewHolder(View view) { super(view);
tv = (TextView) view.findViewById(R.id.tv_item_shopcart_shopname);
}
}调用：
mAdapter.setOnItemClickLitener(new OnItemClickLitener() { @Override
public void onItemClick(View view, int position) { //点击事件
} @Override
public void onItemLongClick(View view, int position) { //长按事件
}
});
这样就完成了RecyclerView的点击事件了。
