我需要在docker工具箱中运行降级的docker版本。
我已按照this指南安装了必需的docker-machine版本（删除了先前的默认设置并安装了新的默认版本），并借助package com.MyApps.screen;
import android.content.Context;
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.Sinergi.VenusERP10_Client.R;
import java.util.ArrayList;
import com.squareup.picasso.Picasso;
public class ProductAdapter extends RecyclerView.Adapter<ProductAdapter.ProductViewHolder> {
private Context mContext;
private ArrayList<ProductItem> arProductList;
private OnItemClickListener mListener;
public interface OnItemClickListener{
void onItemClick(int position);
}
public void setOnItemClickListener(OnItemClickListener listener) {
mListener = listener;
}
public ProductAdapter(Context context, ArrayList<ProductItem> productList) {
mContext = context;
arProductList = productList;
}
@Override
public ProductViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(mContext).inflate(R.layout.product_item, parent, false);
return new ProductViewHolder(v);
}
@Override
public void onBindViewHolder(ProductViewHolder holder, int position) {
String imageUrl = arProductList.get(position).getsImageURL();
holder.tvCode.setText(arProductList.get(position).getsCode());
holder.tvName.setText(arProductList.get(position).getsName());
holder.tvPrice.setText(arProductList.get(position).getsPrice());
holder.tvDesc.setText(arProductList.get(position).getsDescription()); Picasso.with(mContext).load(imageUrl).fit().centerInside().into(holder.ivImage);
}
@Override
public int getItemCount() {
return arProductList.size();
}
public class ProductViewHolder extends RecyclerView.ViewHolder {
ImageView ivImage;
TextView tvCode;
TextView tvName;
TextView tvPrice;
TextView tvDesc;
public ProductViewHolder(View itemView) {
super(itemView);
ivImage = itemView.findViewById(R.id.ivImage);
tvCode = itemView.findViewById(R.id.tvCode);
tvName = itemView.findViewById(R.id.tvName);
tvPrice = itemView.findViewById(R.id.tvPrice);
tvDesc = itemView.findViewById(R.id.tvDesc);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mListener != null) {
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION) {
mListener.onItemClick(position);
}
}
}
});
}
}
}
命令设置了环境。
当我键入docker-machine env default时，我期望看到已安装的Docker版本（1.13.1），但仍为18.03 ...，即使在重新启动docker toolbox应用程序之后。该如何解决？
