Question

在“切断绳索”级别清除屏幕中，分数会增加到您在关卡中获得的分数值。我怎么能这样做？我尝试使用for循环，一旦我达到该值就停止递增，但这会导致我的应用程序崩溃。我想它需要在每个增量上设置textview的文本。有什么想法吗？

目前，这就是我将比分拉到游戏结束时的显示方式：

// get score and set text field
        scorePreferences = getSharedPreferences("score", 0);
        score = scorePreferences.getInt("score", 0);
        scoreValue.setText(Integer.toString(score));

我希望它增加到首选项中保存的值。我试着这样做：

for (int i = 0; i < score; i++) {
    scoreValue.setText(i);
}

记录cat消息：

编辑：我写了我的计时器来计算这样的分数：

public void scoreTimer() {
        timer.scheduleAtFixedRate(new TimerTask() {
            public void run() {
                if (incrementScore < score) {
                    incrementScore++;
                    scoreValue.setText(String.valueOf(incrementScore));
                }
            }
        }, delay, period);
    }

但我现在得到这个错误：

我猜我需要使用“asynchronise”或“runonuithread”方法？但我不知道该怎么做？

Answer 1

将分数设为String

for (int i = 0; i < score; i++) {
    scoreValue.setText(String.valueOf(i));
}

实际上，当您将int传递给setText()方法时，它会将其作为资源ID并尝试在字符串资源中找到该字符串（使用res / string.xml编写）。这就是为什么你有一个ResourceNotFoundException：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.main.francois/com.main.francois.GameOverActivity}:
android.content.res.Resources$NotFoundException: String resource ID #0x0

以与Doodle Jump和Cut the Rope相似的方式增加分数
