如何将 int 转换为在 textView 中设置

Question

当我将productQuantity String更改为整数应用程序崩溃时遇到问题，我无法理解错误，但他将我带到这里：holder.quantity.setText(currentItem.getProductQuantity());当我施法时setText(currentItem.getProductQuantity())它不起作用package com.original.original.original.admin;public class ProductItem {    String productName;    String productCode;    String productBuyPrice;    String productSalePrice;    int productQuantity;    private String key;    public ProductItem() {    }    public ProductItem(String productName, String productCode, String productBuyPrice, String productSalePrice, int productQuantity) {        this.productName = productName;        this.productCode = productCode;        this.productBuyPrice = productBuyPrice;        this.productSalePrice = productSalePrice;        this.productQuantity = productQuantity;    }//    @Exclude    public String getKey() {        return key;    }//    @Exclude    public void setKey(String key) {        this.key = key;    }    public String getProductCode() {        return productCode;    }    public String getProductName() {        return productName;    }    public String getProductBuyPrice() {        return productBuyPrice;    }    public String getProductSalePrice() {        return productSalePrice;    }    public int getProductQuantity() {        return productQuantity;    }}而这个onBindView方法@Override    public void onBindViewHolder(productViewHolder holder, int position) {        ProductItem currentItem = items.get(position);        holder.name.setText(currentItem.getProductName());        holder.code.setText(currentItem.getProductCode());        holder.buyPrice.setText(currentItem.getProductBuyPrice());        holder.salePrice.setText(currentItem.getProductSalePrice());        holder.quantity.setText(currentItem.getProductQuantity());    }

Answer 1

尝试 String.valueOf(YOUR_VALUE);

就像是 textView.setText(String.valueOf(7));

在你的情况下，我想，

holder.quantity.setText(String.valueOf(currentItem.getProductQuantity()));

Answer 2

如果您确定“holder.quantity”和“currentItem”不为空，请使用此代码

holder.quantity.setText(String.valueOf(currentItem.getProductQuantity()));
