Java 随机变量导致的运行时错误

此代码正在生成以下错误

                }

            }
        });
    }

}

正如您所看到的，返回类型是int

android.content.res.Resources$NotFoundException:字符串资源ID#0xffca961

改变这个

public static int rgb (int red, int green, int blue)

Added in API level 1
Return a color-int from red, green, blue components. The alpha component is implicity 255 (fully opaque). These component values should be [0..255], but there is no range check performed, so if they are out of range, the returned color is undefined.

Parameters
red Red component [0..255] of the color
green   Green component [0..255] of the color
blue    Blue component [0..255] of the color

到

setText（int）

查找具有所述id的资源，如果未找到，则获取

ResourceNotFoundException

您需要的是

setText（CharacterSequence）

编辑：

正如Chris Stratton所建议的，您使用

setText

显示的次数超过两次。每次将新数据设置为

Textview

如果要追加数据，请使用

append

而不是

setText

---

或者您可能打算将颜色设置为您想要的文本视图。

虽然传递裸整数被错误地解释为资源ID是正确的，但根本不清楚其目的是将该颜色的值显示为可打印的数字，特别是调用setText（）两次不可能完成任何有用的事情。@ChrisStratton right错过了它。也许op应该使用appender你是说调用setTextColor（）而不是setText（）？非常感谢！！克里斯斯特拉顿

display.setText(Color.rgb(crazy.nextInt(265), crazy.nextInt(265),crazy.nextInt(265)));

display.setText(String.valueOf(Color.rgb(crazy.nextInt(265), crazy.nextInt(265),crazy.nextInt(265))));
