以下是我遇到问题的代码

package com.example.imhungry;

import java.util.Random;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;


public class ImHungry extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_im_hungry);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_im_hungry, menu);
        return true;
    }

    Random randomGenerator = new Random();
    int randomInt = randomGenerator.nextInt(8);
    String wordList[] = new String[8];
    {
        wordList[0] = "Mexican";
        wordList[1] = "American";
        wordList[2] = "Barbeque";
        wordList[3] = "Chinese";
        wordList[4] = "Indian";
        wordList[5] = "Italian";
        wordList[6] = "Thai";
        wordList[7] = "Viatnamese";
        wordList[8] = "Middle Eastern";

    }


 String wordToDisplay = wordList[randomInt];


}

Answer 1

您正在 8-String数组中添加九个字符串！删除这一行：

wordList[8] = "Middle Eastern";

或者让你的数组保存 9 字符串：

String wordList[] = new String[9];
