如何读取 XML 文件并将其作为带有所有标签和白色字符的字符串传递给 setText [Android]

Question

我想读取 XML 文件，将其保存为字符串并传递给 setText。我不想解析它，但在我的智能手机屏幕上看到它带有所有标签和白色字符，例如

<a>
  <b>some text</b>
</a>

不是：

some text

怎么做？

Answer 1

使用FileInputStream读取文件：

File file = new File(<FilePath>);
if (!file.exists()) {
  System.out.println("File does not exist.");
  return;
}
if (!(file.isFile() && file.canRead())) {
  System.out.println(file.getName() + " cannot be read from.");
  return;
}
try {
  FileInputStream stream = new FileInputStream(file);
  char current;
  while (stream.available() > 0) {
    current = (char) stream.read();
    //Do something with character
  }
} catch (IOException e) {
  e.printStackTrace();
}

仅供参考，这是我解决问题的方法：

    public String readXML() {

        String line;
        StringBuilder total = new StringBuilder();

        try {
            InputStream is = activity.getAssets().open("subjects.xml");

            BufferedReader r = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            total = new StringBuilder();

            while ((line = r.readLine()) != null) {
                total.append(line + "\n");
            }

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

        return total.toString();
    }
