android - 從文本文件逐行讀取

Question

我有下面的代碼，我知道它在Java中工作。我現在正在嘗試做和Android應用程序中的等價物。操作非常簡單：我需要在類中使用方法（在同一個工作區中），我首先需要從我存儲在/res/raw中的文本文件中刪除這些行。

基本上我需要調用駐留在Android Activity類的Java類中的此方法。這怎麼可能？

活動課片段（CaptureActivity.java）：

setContentView(R.layout.orientation); 
         try { 
          SentenceGenerator sentenceGenerator = new SentenceGenerator(); 
          ArrayList<String> firstState = stateGenerator.getState(resultOutput, result, result); 
          String viewPoint = firstState.get(0); 
          String object = firstState.get(1); 
          String subject = firstState.get(2); 
          Thing subjectInfo = new Thing(); 
          if(resultOutput.equals("Sliema")){ 
           Sliema sliema = new Sliema(); 
           subjectInfo = sliema.getInfo(viewPoint, object, subject); 
          } 
          try { 
           String s = sentenceGenerator.generateSentence("start.txt", "middle.txt", "end.txt", resultOutput, viewPoint, object, subject, subjectInfo.type, subjectInfo.name, subjectInfo.properties, false); 
           TextView instructionTextView = (TextView) findViewById(R.id.instructionTextView); 
           instructionTextView.setText(s); 

          } catch (Exception e) { 
          } 
         } catch (ClassNotFoundException e) { 
         } 

的Java類片段（SentenceGenerator.java）：

public static ArrayList<String> getLines(String filename) throws Exception { 
    ArrayList<String> lines = new ArrayList<String>(); 
    FileInputStream fstream = new FileInputStream(filename); 

    BufferedReader br = new BufferedReader(new InputStreamReader(fstream)); 
    String strLine; 
    while ((strLine = br.readLine()) != null) { 
     lines.add(strLine); 
    } 
    in.close(); 
    return lines; 
} 

感謝您的幫助提前！

變化如下代碼：

 BufferedReader br = new BufferedReader(new InputStreamReader(in)); 
String strLine; 
while ((strLine = br.readLine()) != null) { 
    lines.add(strLine); 
} 

到

Scanner br = new Scanner(new InputStreamReader(in)); 
while (br.hasNext()) { 
    String strLine = br.nextLine(); 
    lines.add(strLine); 
} 

這應該工作。 希望這有助於！
