我在运行时得到了一个清晰的列表(布局之间没有空间),但是当我向下滚动时,所有内容都会受到干扰,并在要查看的布局之间形成一个大空间
package com.example.recyclerview;
// this is the code of the Adapter
//there is also a card class (datatype for the arraylist declared in mainActivity
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import java.util.ArrayList;
public class Adapter extends RecyclerView.Adapter<Adapter.ViewHolder> {
Context context;
ArrayList<card> arl ;
public Adapter(Context context, ArrayList arl){
this.context = context;
this.arl = arl;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.card,parent,false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder ;
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
holder.img.setImageResource(arl.get(position).img);
holder.name.setText(arl.get(position).name);
holder.contact.setText(arl.get(position).contact);
}
@Override
public int getItemCount() {
return arl.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView img;
TextView name;
TextView contact;
public ViewHolder(View itemView){
super(itemView);
name = itemView.findViewById(R.id.name);
img = itemView.findViewById(R.id.imageView);
contact = itemView.findViewById(R.id.details);
}
}
}
期望有一个视图,其中滚动时两个视图之间的间距不能有任何变化
