        setContentView(R.layout.activity_main); 
        setStartUpWorldValues();
        setStarUpScreenText(); //when this is removed, application runs but text from object is not displayed.
    }
    protected void setStartUpWorldValues(){
        earth.setPlanetColonies(1);                      //Set Planet Colonies to one

【问题讨论】：

  • 根据错误，您是否确保所有文本视图都正确命名？

标签： java android xml string runtime-error


【解决方案1】：

根据 LogCat，您缺少引用的字符串资源：

Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x1755

在第 28 行

at chaper.two.hello_world.MainActivity.setStarUpScreenText(MainActivity.java:28)

这就是这一行：

planetMassValue.setText(earth.planetMass);

您的res/values/strings.xml 似乎缺少WorldGen 类的对象earth 中的属性planetMass 指向的字符串。

如果字符串存在，并且您正确引用它，则 R 文件可能存在问题。所以只需做一个项目 -> 清理，以便重建 R 文件。

【讨论】：

  • 如果你使用的是 IDEA/Studio，或者删除 R.java 和 "File->Invalidate caches"。
  • 感谢您的建议。我删除了对 earth.planetmass 的引用并改为放置“测试”，但仍然出现错误。我将生成的日志放在帖子中。
  • 这听起来确实像是资源文件中的错误。如果你还没有，你应该尝试重建它。除此之外，我没有想法。
  • 没关系我改错了字符串。现在可以了。谢谢我被困了一段时间。谢谢你。
