我感觉资产文件的路径是错误的，但我不确定要使用的正确路径。我仔细检查了文本文件实际上位于assets什么让我认为它错误的文件或目录是因为错误没有这样的文件或目录？

问题代码周围有条件代码，用于存储不同的字段。代码指定数组中是否有四个元素，然后用文件中的数据填充数组列表。如果不满足此条件，则日志将显示错误。该文件名为

  • 测验1.txt
  • 测验2.txt
  • 测验3.txt

这是 LogCat

如果你使用它，你将确保路径是正确的。

AssetManager assetManager = getAssets();
String quizes[] = assetManager.list("myquizfolder");
for(String quiz : quizes) {
    InputStrem in = assetManager.open("myquizfolder/" + quiz);
}
