包的名称是com.HJ.calculator

问题是我尝试在eclipse中更改App主题。它在此之前有效，但在此之后，无论我改变什么主题，它都无法正常工作。我试着换成AppBaseTheme。但它仍然没用。请帮助。

@Evjin

中的十六进制代码指的是

public static final int AppTheme=0x7f0b008c;

此行位于我的应用程序中的R.java文件中。在我的MainActivity.java中，我没有使用R.id在任何地方都可以使用Apptheme。

Answer 1

这Exception：

android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f0b008c a=-1 r=0x7f0b008c}

通常在尝试通过其R.id设置某些内容时触发，但是您要发送另一个未绑定到资源的整数。

修改

正如@kha在评论中提到的，属性android:background期望integer id绑定到可绘制或颜色资源，而不是主题。

例如，如果要将其设置为黑色，则可以添加此项：

android:background="@android:color/black"

不幸的是（AppName）已停止在模拟器
