运行尝试显示对象ListView的片段时会发生此异常。我已经研究了异常但是其他情况的解决方案似乎与“setText”函数有关,或者其他任何尝试以字符串形式显示除字符串之外的东西。我真的不确定还能说些什么。提前谢谢!

答案 0 :(得分:0)
发现您的错误。它位于IngAdapter下面的行中
super(context, 0, ings);
在这里,第二个参数应该是资源名称,并且永远不应该被任何int值硬编码。这是将用于创建列表中每一行的布局标识符。如果您只想显示可以使用的名称列表 - android.R.layout.simple_list_item_1 ,这是android中可用于显示字符串值的标准。
所以将代码更改为
super(context, android.R.layout.simple_list_item_1, ings);
