保存文件不能工作總是android

Question

所以開始作爲按鈕的問題，只是意味着我的文件有問題。我想將數字保存到我的文件中，並且還選擇了我所選的語言。該languege完美的作品，但是當我試圖做同樣的我的號碼，它只是出問題

所以這是我languege文件的

french.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      try{ 
       buttonSound.start(); 
       String FILENAME = "LangFile"; 
       String data ="FR"; 
       FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE); 
       fos.write(data.getBytes()); 
       fos.close(); 
       FILENAME="TempFile"; 
       data="0"; 
       FileOutputStream fostemp = openFileOutput(FILENAME, Context.MODE_PRIVATE); 
       fostemp.write(data.getBytes()); 
       fostemp.close(); 
       startActivity(new Intent("com.technopolisapp.LOGOTECHNOPOLIS")); 
      } catch (FileNotFoundException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
      finally{ 
       finish(); 
      }    
     } 
    }); 

在這裏，我保存2個字母的按鈕被按下 代碼，這是再次讀取並且作出與選擇的languege按鈕的代碼

try{ 
     String FILENAME = "LangFile"; 
     FileInputStream fos = openFileInput(FILENAME); 
     byte[] b = new byte[2]; 
     fos.read(b); 
     fos.close(); 
     if(new String(b).equalsIgnoreCase("NL")){ 
      Tower.setText(classNamesDutch[0]); 
      Puzzle.setText(classNamesDutch[1]); 
      Mirror.setText(classNamesDutch[2]); 
      Tangram.setText(classNamesDutch[3]); 
      Frog.setText(classNamesDutch[4]); 
     } 
     if(new String(b).equalsIgnoreCase("GB")){ 
      Tower.setText(classNamesEnglish[0]); 
      Puzzle.setText(classNamesEnglish[1]); 
      Mirror.setText(classNamesEnglish[2]); 
      Tangram.setText(classNamesEnglish[3]); 
      Frog.setText(classNamesEnglish[4]); 
     } 
     if(new String(b).equalsIgnoreCase("FR")){ 
      Tower.setText(classNamesFrench[0]); 
      Puzzle.setText(classNamesFrench[1]); 
      Mirror.setText(classNamesFrench[2]); 
      Tangram.setText(classNamesFrench[3]); 
      Frog.setText(classNamesFrench[4]); 
     } 
    }catch (java.io.FileNotFoundException e) { 
     } catch (IOException e) { 
     e.printStackTrace(); 
    } 

現在，這是我的保存和閱讀我的數字代碼

public void Savefile(){ 
    int level=0; 
    String data; 
    try{ 
     String FILENAME = "TowerFile"; 
     FileInputStream fos = openFileInput(FILENAME); 
     byte[] b = new byte[1]; 
     fos.read(b); 
     fos.close();    
     if(new String(b).equalsIgnoreCase("1")){ 
      level=1; 
     } 
     if(new String(b).equalsIgnoreCase("2")){ 
      level=2; 
     } 
     if(new String(b).equalsIgnoreCase("3")){ 
      level=3; 
     } 
     if(new String(b).equalsIgnoreCase("4")){ 
      level=4; 
     } 
     if(new String(b).equalsIgnoreCase("5")){ 
      level=5; 
     } 
     if(level!=1 || level!=2 || level!=3 || level!=4 || level!=5){ 
      FILENAME="TowerFile"; 
      data="een"; 
      FileOutputStream fostemp = openFileOutput(FILENAME, Context.MODE_PRIVATE); 
      fostemp.write(data.getBytes()); 
      fostemp.close(); 
     } 
    } catch (FileNotFoundException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
} 

這是我想讀它

try{ 
     String FILENAME = "TowerFile"; 
     FileInputStream fos = openFileInput(FILENAME); 
     byte[] b = new byte[1]; 
     fos.read(b); 
     fos.close(); 
     if(new String(b).equalsIgnoreCase("1")){ 
      button1.setVisibility(Button.GONE); 
     } 
     if(new String(b).equalsIgnoreCase("2")){ 
      level=2; 
     } 
     if(new String(b).equalsIgnoreCase("3")){ 
      level=3; 
     } 
     if(new String(b).equalsIgnoreCase("4")){ 
      level=4; 
     } 
     if(new String(b).equalsIgnoreCase("5")){ 
      level=5; 
     } 
    }catch (java.io.FileNotFoundException e) { 
    } catch (IOException e) { 
      e.printStackTrace(); 
    } 

所以，我真的不明白哪裏出了問題，此刻

Answer 1

你想用Context.openFileStream(Context.MODE_PRIVATE)的方式。它沒有解釋爲什麼你必須這樣做，我假設操作系統的權限，但這應該適合你。
