java - 如何将 int 转换为在 textView 内设置

当我将 productQuantity 字符串更改为整数时，应用程序崩溃，我遇到问题，我无法理解该错误，但他引导我到这里:

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

当我施放setText(currentItem.getProductQuantity())时它不起作用

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;
    }
}

还有这个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);

类似textView.setText(String.valueOf(7));

就你的情况而言，我想，

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