Android DB（DatabaseHandler）抛出EXCEPTION
[英]Android DB(DatabaseHandler) throws EXCEPTION
问题描述
我正在使用DatabaseHandler。 对于游戏中使用的所有图像（标志），DatabaseHandler都是resposibole。 每当我的活动刷新并加载另一张图像时（我的数据库中就有218张图像）。 在某种程度上，我遇到了致命异常或：
04-19 23:00:41.177: W/dalvikvm(10808): threadid=1: thread exiting with uncaught exception (group=0x41674db8)

ClassicMode.java ，第82行-您尝试将0设置为资源值。 我只能猜测，但是请检查您是否未执行以下操作：
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
如果要在TextView中插入数字值，请始终使用"" + numericalValue或String.valueOf(numericalValue)
更新：
好吧，现在我们了解更多。 首先，在冒险接收资源ID为0的问题之前，您应该创建一个条件：
if(imageResource !=0)
{
//create Drawable and put it into a View
}
这将修复崩溃。 至于第二个问题，您将需要检查传递给getResources().getIdentifier(uri, pic2, getPackageName());的值getResources().getIdentifier(uri, pic2, getPackageName()); 与文档，并弄清楚该方法为何返回0。
