java - 错误: Cannot find getter for field in Android Room

这是android studio中的一个简单的类:

package com.loghty.bahaa.loghty;

import android.arch.persistence.room.ColumnInfo;
import android.arch.persistence.room.Entity;
import android.arch.persistence.room.PrimaryKey;
import android.support.annotation.NonNull;


@Entity (tableName = "Chars")
public class Chars {

    @PrimaryKey(autoGenerate = true)
    @ColumnInfo(name = "char_Id")
    private int pCId;

    @NonNull
    @ColumnInfo(name = "char_field")
    private String mcharField;

    // Getters and setters

    public String getMcharField() {
        return mcharField;
    }

    public void setMcharField(@NonNull String mcharField) {
        this.mcharField = mcharField;
    }

    public int getpCId() {
        return pCId;
    }
}

但是，当我构建应用程序时，我在pCId字段中收到此错误:



我检查了很多次代码，但没有什么奇怪的。错误到底在哪里？

最佳答案

将变量从私有(private)更改为 protected 或公共(public)

来自private int pCId;
至protected int pCId;
