Question

我想制作一个骰子游戏，我使用了一个github项目（https://github.com/dylanmtaylor/Simple-Dice）。

MainActivity可在此处找到：https://github.com/dylanmtaylor/Simple-Dice/blob/master/src/com/dylantaylor/simpledice/RollDice.java

我想得到骰子的价值

例如： 如果第一个骰子是1而第二个骰子是6，那么我总共需要7个骰子。

我创建了一个更改文本视图的按钮，此按钮尝试获取骰子的数量。

TextView hwTextView = (TextView)findViewById(R.id.textView8);
                hwTextView.setText(String.valueOf(diceSum));

我试图获得价值＆＃34; diceSum＆＃34;，＆＃34; diceImages＆＃34;，＆＃34; dice＆＃34 ;，＆＃34; dice[roll[0]＆＃34;，＆＃34; dice[roll[1]＆＃34;但那并没有显示出一个数字。

我怎样才能尝试获得骰子的价值？

我不明白为什么你的代码没有用。我自己根据＆＃34; Scarne's dice game(pig)＆＃34;做了一个非常小的游戏。我自己面临着检索掷骰子价值的挑战。记住，我只是使用一个骰子。这就是我所做的：

int userScore;
private int[] diceArray = {R.drawable.d1, R.drawable.d2, R.drawable.d3,
        R.drawable.d4,R.drawable.d5,R.drawable.d6};

@Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

}

public void onRollBtnClicked() {
    ImageView diceFace = (ImageView) findViewById(R.id.diceFaceImageView);
    userScore = randomIntegerGenerator(1,6); // this is what you need
    diceFace.setImageResource(diceArray[userScore]);

}

// function to return random integer from min to max
public int randomIntegerGenerator(int min, int max) {
     return random.nextInt((max - min) + 1) + min;
}

我将我的掷骰价值存储在 userScore 中。您可以使用类似的方法。
