我们适配器中也相应的把 textview 给删除

package nd.no.xww.bottomnavigationlayout;

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import com.bumptech.glide.Glide;

import java.util.List;
import java.util.Map;

/**

public class RecyclerGridAdapter extends RecyclerView.Adapter<RecyclerGridAdapter.ViewHolder> {

Context context;
List<Map<String, Object>> data;

public RecyclerGridAdapter(Context context, List<Map<String, Object>> data) {
this.data = data;
this.context = context;
}

@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recycler_one_view_2_item, viewGroup, false);
return new ViewHolder(view);
}

@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int i) {
Glide.with(context).load(data.get(i).get("pic")).into(holder.img);
holder.name.setText(data.get(i).get("name").toString());
}

@Override
public int getItemCount() {
return data.size();
}

public class ViewHolder extends RecyclerView.ViewHolder {

ImageView img;
TextView name;

public ViewHolder(@NonNull View itemView) {
super(itemView);

img = itemView.findViewById(R.id.img_recy_item_2_pic);
name = itemView.findViewById(R.id.tv_recy_item_2_name);

}
}
}
然后,是数据做一下简单的修改,把对应的 desc 数据给删除:

private void addGridData() {
Map<String, Object> map = null;
Random random = new Random();
for (int i = 0; i < 30; i++) {
int n = random.nextInt(pics.length);
map = new HashMap<>();
map.put("pic", pics[n]);
map.put("name", names[n]);
gridData.add(map);
}
}
