我得到一个资源未找到异常，我不确定为什么。我在想这个错误的方式吗？我试图将 setTextColor 标签移动到不同的位置，但它仍然无法正常工作。我让它正常工作的唯一方法是在 onCreate 方法中。所以应用程序能够在 onCreate 中找到权限 ID，但不能在其他方法中找到？有人知道为什么吗？

ViewPager 适配器：

这个

  home.setText(Color.GRAY); //expecting  a resource id which is an int
  // the resource does not exist. hence you get ResourceNotFoundException

例子：

考虑到您有如下字符串资源

   <string name="app_name">MyAppName</string>

您可以执行以下操作

  home.setText(R.string.app_name);
  // the resource referred exists in string.xml.

http://developer.android.com/reference/android/widget/TextView.html。

检查文档以获取更多信息。

public final void setText (int resid)
//expects a resource id which is an integer.

不确定你在做什么。如果要显示颜色值，可以执行以下操作。

 home.setText(String.valueOf(Color.GRAY));
