您可以将文件放在项目的资产目录中并使用

      AssetManager am = context.getAssets();

您可以使用以下代码列表来读取文本文件的内容。

获取路径：

File file = app.getFilesDir();
String path = file.getAbsoluteFile().getAbsolutePath() + "<filename.extension>";

--------------------------------------------------------

public static String readAllContents(String path) {

    String fileContents = null;

    try {
        InputStream inputStream = new FileInputStream(path);
        if ( inputStream != null ) {
            InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
            String receiveString = "";
            StringBuilder stringBuilder = new StringBuilder();

            while ( (receiveString = bufferedReader.readLine()) != null ) {
                stringBuilder.append(receiveString);
            }

            inputStream.close();
            fileContents = stringBuilder.toString();
        }
    }

    catch (FileNotFoundException e) {
        Log.e("exception", "File not found: " + e.toString());
    } catch (IOException e) {
        Log.e("exception", "Can not read file: " + e.toString());
    }

    return fileContents;
}
