我在內部存儲器中為我的應用程序創建文件夾時遇到了一些問題.我正在使用這段代碼：

public static void createFoldersInInternalStorage(Context context){

try {

File usersFolder = context.getDir("users", Context.MODE_PRIVATE);

File fileWithinMyDir = new File(usersFolder, "users.txt"); //Getting a file within the dir.

FileOutputStream out = new FileOutputStream(fileWithinMyDir); //Use the stream as usual to write into the file.

File dataFolder = context.getDir("data", Context.MODE_PRIVATE);

File fileWithinMyDir2 = new File(dataFolder, "data.txt"); //Getting a file within the dir.

FileOutputStream out2 = new FileOutputStream(fileWithinMyDir2); //Use the stream as usual to write into the file.

File publicFolder = context.getDir("public", Context.MODE_PRIVATE);

File fileWithinMyDir3 = new File(publicFolder, "public.txt"); //Getting a file within the dir.

FileOutputStream out3 = new FileOutputStream(fileWithinMyDir3); //Use the stream as usual to write into the file.

} catch(FileNotFoundException e){

e.printStackTrace();

}

}

因此創建文件夾但在其名稱前面有“app_”開頭：app_users,app_data,app_public.有沒有辦法用我給出的名字創建文件夾？另一個問題：我想首先創建文件夾文件,而不是所有其他文件夾“數據,公共,用戶”….最后一個問題：如果我想創建一個文件,我怎么能給出正確的文件夾路徑內存中的Documents / Users / myfile.txt？

提前致謝！
