FileOutputStream創建文件，但FileInputStream

Question

我正在使用FileOutputStream在不是我的MainActivity的活動中創建文件。該文件已創建，當我銷燬活動時，我需要的數據被寫入，但是當我從我的MainActivity重新啓動活動時，無法找到該文件。我可以在我的代碼中更改什麼，以便我沒有得到fileNotFoundException？相關的代碼是在這裏：

try { 
fis = new FileInputStream("words"); 
ois = new ObjectInputStream(fis); 
} catch (FileNotFoundException e1) { 
fnfexception = e1; 

} catch (IOException ioe) { 
ioe.printStackTrace(); 
} 
EOFException eof = null; 

int counter = 0; 
if (fnfexception == null) { 
while (eof == null) { 
    try { 
    if (words == null) words = new Dict[1]; 
    else words = Arrays.copyOf(words, counter + 1); 
    words[counter] = (Dict) ois.readObject(); 
    counter++; 
    } catch (EOFException end) { 
    eof = end; 
    } catch (IOException ioe) { 
    ioe.printStackTrace(); 
    } catch (ClassNotFoundException e1) { 
    e1.printStackTrace(); 
    } 
} 
} 
wordStartCount = counter; 
wordCount = counter; 
fnfexception = null; 

try { 
fos = openFileOutput("words", Context.MODE_PRIVATE); 
oos = new ObjectOutputStream(fos); 

} catch (FileNotFoundException e1) { 
fnfexception = e1; 

} catch (IOException ioe) { 
ioe.printStackTrace(); 
}

你用錯誤的方式，從內部文件讀取，使用下面的代碼

try { 
    FileInputStream fis = context.openFileInput("file_name"); 
    int content; 
    StringBuilder str = new StringBuilder(); 
    while ((content = fis.read()) != -1) 
     str.append((char) content); 
    fis.close(); 
    String savedText = str.toString(); 
} catch (IOException e) { 
    e.printStackTrace(); 
}
