Android文件未加载

Question

我有一种感觉，资产文件的路径是错误的，但我不确定正确的路径使用。我有双重检查的文本文件实际上位于assets是什么让我觉得它的错误文件或目录是因为错误没有这样的文件或目录？

在用于存储不同字段的问题代码周围有条件代码。该代码指定数组中是否等于四个元素，然后使用该文件中的数据填充数组列表。如果没有这个条件，那么日志会显示错误。该文件被命名为

• quiz1.txt
• quiz2.txt
• quiz3.txt

这里是logcat的

如果你使用这个，你会确保路径是正确的。

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