java - android - 从文本文件中逐行读取

Question

我有以下代码，我知道它可以在 Java 中运行。我现在正在尝试在 Android 应用程序中做同样的事情。操作非常简单:我需要使用类中的方法(在同一工作区中)，首先需要从存储在 /res/raw 中的文本文件中获取行.

基本上，我需要从 Android Activity 类调用驻留在 Java 类中的此方法。这怎么可能？

Activity 类 fragment (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) {
                        }

Java 类 fragment (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;
}

感谢您提前提供的任何帮助!

更改以下代码:

     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);
}

这应该有效。希望这有帮助!
