使用我制作的上下文从 sharedPreference 方法获取 Cast 错误

问：

这是我的共享首选项中的代码部分，我从中得到错误：

package com.example.myapplication;

import android.content.Context;
import android.content.SharedPreferences;

public class SharedPreferenceHelper {

    private final SharedPreferences sharedPreferences;
    private final Context context;

    public SharedPreferenceHelper(Context context) {
        this.context = context;
        sharedPreferences = context.getSharedPreferences(this.context.getString(R.string.Profile_SharedPreferences), Context.MODE_PRIVATE);
    }

    public String getName(String key) {
        switch (key) {
            case "A":
                return this.sharedPreferences.getString((this.context.getString(R.string.Profile_SharedPreferences_Name_Key_Button_A)), "");
            case "B":
                return this.sharedPreferences.getString((this.context.getString(R.string.Profile_SharedPreferences_Name_Key_Button_B)), "");
            case "C":
                return this.sharedPreferences.getString((this.context.getString(R.string.Profile_SharedPreferences_Name_Key_Button_C)), "");
            default:
                return "Error";
        }

    }

我尝试调试，但我不明白为什么这会导致异常错误，我希望在以下行： 调试以查找是否检测到密钥？ 这与我在 resources 中的密钥名称匹配： resources

this.sharedPreferences.getString((this.context.getString(R.string.Profile_SharedPreferences_Name_Key_Button_A)), "");

返回一个 String 值，当我进入调试模式时，我看到以下内容：

这也是我从 Main 调用方法的地方：

    @Override
    protected void onStart() {
        super.onStart();
        SharedPreferenceHelper sharedPreferenceHelper = new SharedPreferenceHelper(getApplicationContext());
        eventA_Button.setText(String.valueOf(sharedPreferenceHelper.getName("A")));
}
