我正在使用DatabaseHandler。 DatabaseHandler是我在游戏中使用的所有图像（标志）的resposibole。每次我的活动刷新并加载另一个图像（我的数据库有218个图像）。在某些时候，我得到致命的异常或：

很抱歉有很长的代码和堆栈跟踪，但我提供了所需的所有信息。
答案 0 :(得分：0)
ClassicMode.java，第82行 - 您正尝试将0设置为资源值。我只能猜测，但检查一下你是不是在做这样的事情：
int value; //It sets to 0
someTextView.setText(value); //It thinks you want to set a resource as the text, but there is no resource with id 0
如果要将数值插入TextView，请始终使用
"" + numericalValue或String.valueOf(numericalValue)
更新：
好的，现在我们了解更多。首先，在冒险接收0作为资源ID的问题之前，你应该创建一个条件：
if(imageResource !=0)
{
//create Drawable and put it into a View
}
这将修复崩溃。至于第二个问题，您需要使用文档检查传递给getResources().getIdentifier(uri, pic2, getPackageName());的值，并找出方法返回0的原因。
