我正在尝试制作一个游戏，并且可以成功切换到游戏所在的第二个 Activity ，但是当我在应用程序的第二个 Activity 中单击按钮以调用diceroll方法时，我的应用程序总是崩溃总是崩溃。请帮助我，我是Android新手。
这是代码，我在最后也附了我的错误报告。

最佳答案
问题在这里(在diceroll中):
text.setText(x);
期望整数值表示字符串资源id-因此出现错误:
android.content.res.Resources$NotFoundException: String resource ID #0x5 at
而是:
text.setText(Integer.toString(x));
查看您的所有
setText中是否存在类似错误。
