Android文件未加載

Question

我有一種感覺，資產文件的路徑是錯誤的，但我不確定正確的路徑使用。我有雙重檢查的文本文件實際上位於assets是什麼讓我覺得它的錯誤文件或目錄是因爲錯誤沒有這樣的文件或目錄？

在用於存儲不同字段的問題代碼周圍有條件代碼。該代碼指定數組中是否等於四個元素，然後使用該文件中的數據填充數組列表。如果沒有這個條件，那麼日誌會顯示錯誤。該文件被命名爲

• quiz1.txt
• quiz2.txt
• quiz3.txt

這裏是logcat的

下面是源代碼

如果你使用這個，你會確保路徑是正確的。

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