我最近发现我出于某种原因无法在Android小部件上使用FileInputStream。不幸的是,我无法找到解决方案。 我每次尝试都会得到

  

无法解析方法' openFileInput(java.lang.string)

你能帮帮我吗?

try {
        FileInputStream HomeWorkIN = openFileInput(Class + ".txt");
        InputStreamReader HomeWorkREAD = new InputStreamReader(HomeWorkIN);
        char[] data = new char[ReadingBlock];
        String FinalData = "";
        int Size;
        try {
            while ((Size = HomeWorkREAD.read(data)) > 0) {
                String ReadData = String.copyValueOf(data, 0, Size);
                FinalData += ReadData;
                data = new char[ReadingBlock];
            }
            HomeWork += FinalData;
        } catch (IOException e) {
            e.printStackTrace();
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
