Answer 1

试试这个，你可以从drawable文件夹中读取文件

        String data = "";
        StringBuffer sbuffer = new StringBuffer();
        InputStream is = this.getResources().openRawResource(+
                R.drawable.filetoread);
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        if (is != null) {
            try {
                while ((data = reader.readLine()) != null) {
                    sbuffer.append(data + "\n");
                }
                is.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
         data = sbuffer.toString(),
        }

为什么要将.txt保留在drawable/文件夹中？最好将它保存在assets文件夹中，并按照此SO中的说明进行阅读。

BufferedReader reader = null;
try {
    reader = new BufferedReader(
        new InputStreamReader(getAssets().open("filename.txt")));

    // do reading, usually loop until end of file reading  
    String mLine;
    while ((mLine = reader.readLine()) != null) {
       //process line
       ...
    }
} catch (IOException e) {
    //log the exception
} finally {
    if (reader != null) {
         try {
             reader.close();
         } catch (IOException e) {
             //log the exception
         }
    }
}
