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();}
