Android 读取txt 文件

Android过程：InputStream-InputStremRreader-BufferedReader-String；
其中 InputStream inputStream=getResources().openRawResource(R.raw.abc);//abc 为 在res/raw文件下的txt文件
Java读取外部txt文件
InputStreamReader read = new InputStreamReader( new FileInputStream(file),encoding);//考虑到编码格式

                 


public  String getString( InputStream inputStream) {
  
 InputStreamReader inputStreamReader = null;
    try {
        inputStreamReader = new InputStreamReader(inputStream, "gbk");
    } catch (UnsupportedEncodingException e1) {
        e1.printStackTrace();
    }
    BufferedReader reader = new BufferedReader(inputStreamReader);
    StringBuffer sb = new StringBuffer("");
    String line;
    try {
        while ((line = reader.readLine()) != null) {
            sb.append(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
      sb.close;
    return sb.toString();
}
