I have a directory that is displayed in a ListView. Inside each folder there is a .txt file called Sales ...(Sales112855,Sales122921,Sales122941, ..., ). There is a cat for sorting through files. That is, by clicking on an item from the list, it goes inside the folder and goes through the files there.

The code:

File[] listFile = dir.listFiles();
        for (File f : listFile) {
            if (f.isDirectory() && (!f.getAbsolutePath().equalsIgnoreCase(String.valueOf(dir)))) {
                File[] listFile2 = f.listFiles();
                for (File f2 : listFile2) {
                    Toast.makeText(this, "f2 " + f2, Toast.LENGTH_SHORT).show();
                }
                Toast.makeText(this, "f " + f, Toast.LENGTH_SHORT).show();
            }
        }

Problems like this. I do not know how to make it stop at the file I need. tricks for JDK 8+ I will not be able to use.

you can break, once you found your file

                for (File f2 : listFile2) {
                    Toast.makeText(this, "f2 " + f2, Toast.LENGTH_SHORT).show();
                 if (f2.getName().toLowerCase().endsWith((".txt"))) {
                   // found file
                     break;
                  }
                }
