Android应用上只读取了一些文件

Question

大家下午好， 我在同一目录中有10个文件，但有些文件正在被读取。 我检查了名字，写得很好。

活动从其他活动中获取int“位置”。它就像一个用于加载文件的标识符，其名称在文件“Categorias”中，我把文件的名称放在一个字符串中，然后用“position”读取它，每行的txt放入列表视图的位置。问题是只能读取其中一些文件。我看不出问题了。

for的第一个循环读取fichero =“categorias.txt”。第二个循环读取向量[位置]

谢谢

Java

protected String fichero="categorias.txt";
protected String Nombre;
protected int position;


protected int contarLineasFichero() {
    int lineas = 0;
    try {
        InputStreamReader is = new InputStreamReader(openFileInput(fichero));
        BufferedReader fich = new BufferedReader(is);

        String s;
        while ((s = fich.readLine()) != null)
            lineas++;

        is.close();

    } catch (IOException ex) {
        ex.printStackTrace();
    }
    return lineas;
}

protected void leerFichero() {
    int linea = 0;
    String s;

    try {

                new BufferedReader(new InputStreamReader(openFileInput(fichero)));

            vector[linea] = s;
            linea++;
        }

        fin.close();
    } catch (Exception ex) {

                fout.write(s);
                fout.write("\n");

            }


        }

        fout.close();

    } catch (Exception ex) {
        Log.e("Ficheros", "Error al escribir fichero a memoria interna");
    }
