我在引用映射 EditText 的类方法之一的行中遇到资源未找到异常目的。我不明白为什么我会遇到这个问题。

我有一个名为 store.java 的简单 Java 类它只是映射来自微调器和 EditText. 的数据和一个名为 SpinPizza.java 的类打印它们的值。

Store.java

package com.Lak;

import android.os.Parcel;
import android.os.Parcelable;

public class store implements Parcelable {

    @SuppressWarnings("rawtypes")
    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public store createFromParcel(Parcel in) {
            return new store(in);
        }

        public store[] newArray(int size) {
            return new store[size];
        }
    };
    private static final long serialVersionUID = 1L;
    private String pizzaname;
    private String pizzasize;
    private int n;

    public store() {
    }

    public store(Parcel source) {
          /*
           * Reconstruct from the Parcel
           */
        n = source.readInt();
        pizzaname = source.readString();
        pizzasize = source.readString();
    }

    public void setOrder(String name, String size, int qty) {
        pizzaname = name;
        pizzasize = size;
        n = qty;
    }

    public String getPizzaName() {
        return pizzaname;
    }

    public int getQuantity() {
        return n;
    }

    public String getPizzaSize() {
        return pizzasize;
    }

    public int describeContents() {
        return 0;
    }

    public void writeToParcel(Parcel dest, int flags) {

        dest.writeInt(n);
        dest.writeString(pizzaname);
        dest.writeString(pizzasize);
    }

    /** Called when the activity is first created. */
}

        });
    }
}

最佳答案

数量是一个整数:

public int getQuantity()

所以你应该使用这个:

objText2.setText(String.valueOf(B[i].getQuantity()));

否则，操作系统会尝试为该 int 查找不存在的资源。

详细解释:EditText.setText() 方法被重载，所以它有一个版本用于 String (setText(CharSequence text) ) 和字符串资源 ID 的版本 (setText(int resid))。

关于java - 未找到资源异常，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5444713/
