我应该在哪里查看我的应用代码来解决抛出此异常的问题？我无法解释它：

答案 0 :(得分：1)
您的错误发生在此行代码
上icon.setImageDrawable(res.getDrawable(res.getIdentifier(sIcon, null, null)));
因为Resource.getIdentifier（）是documented，并出现以下错误响应：
如果未找到此类资源，则返回0。 （0不是有效的资源ID。）
尝试调用ID为0的getDrawable（）确实是你的失败。
显然，由于
的结果，您没有任何名称由sIcon包含的资源String sIcon = "com.sj.jsondemo:drawable/" + app.getIcon();
在分配和尝试使用它之间简单地记录sIcon可能是值得的，看看这个名字是否合理 - 也许你正在不正确地构建它。另一种可能性是你的某些情况可能根本没有图标，你可以用它来代替默认或“？”的图片。什么的。
