好的，所以我制作一个应用程序只是为了好玩，它会在屏幕上弹出一个随机数。如果您点击与随机数相同的数字按钮，您将获得一分，如果您点击数字不正确的按钮，您将失去一分。问题是你只有 10 秒的时间来获得足够的分数。无论如何，我的应用程序有两个主要问题。当您点击正确的按钮时，您的分数不会上升。但是，如果您点击了错误的按钮，分数会下降。我觉得这很奇怪。另外，在计时器用完后，我无法设置内容视图来告诉玩家他/她是否赢了。我是否需要进行单独的活动来设置新的内容视图，或者我有不同的错误？

谢谢您的帮助！

这是我的活动课：

您在分数增加后立即生成一个随机数，因此它会上升，但在您点击下一个后会回落if

if (1 == random) {
                playerscore++;
                runOnUiThread(new Runnable() {
                    public void run() {
                        score.setText("Your Score Is " + playerscore);
                    }
                });
                randomnumber();  // there is a new nunmber
            }

            if (1 != random) {  // this should be an else
                playerscore--;
                runOnUiThread(new Runnable() {
                    public void run() {
                        score.setText("Your Score Is " + playerscore);
                    }
                });
                randomnumber();

我已在您遇到问题的上述代码中添加注释

另外，在计时器用完后，我无法设置内容视图来告诉玩家他/她是否赢了。我是否需要进行单独的活动来设置新的内容视图，或者我有不同的错误？

不知道你有什么问题很难说。但这可以做到。但是，我建议为此使用AlertDialog，或者您可以在ActivitythemeDialogmanifest

此外，您可以只使用一个侦听器，Buttons因为它们都做几乎相同的事情，或者在 xml 中通过将onClick函数设置为所有它们相同

<Button
    android:id="@+id/button1
    ...
    android:onClick="functionName"/>

然后在java中

public void functionName(View v)
{
     // v is the button that was clicked
}

或者在java中通过实现你的监听器，这里是onClick，

button1.setOnClickListener(this);  // do this for each
public void onClick(View v)
{
    // v is still the button clicked
}

然后获取被点击按钮的文本，并与随机数进行比较

你有错误的if用法。正确选择按钮后，您将生成下一个数字并再次检查是否random!=that_button_number。它几乎每次都会发生，所以它会降低你的分数。

     if (random == 3) {randomNumber()}else{}

不是

if(random==3){
      randomNumber();
  };     
if(random!=3){};

您不能调用setContentView应用程序的运行时。你会得到RuntimeException. 你可以：

  • 隐藏一种布局，显示新的setVisibility
  • 利用Frame layout
  • 许多其他事情，例如片段事务或附加新视图

我看过你的代码，我在你的代码中发现了两个问题。1.你应该提取Listener，为每个按钮写它是很愚蠢的。2.在andoid中，不允许在其他线程中操作UI，应该使用Handle
