将文件放在
/assets项目的文件夹中，然后
InputStream通过打开文件即可
AssetManager：
InputStream in = getAssets().open("data.txt");然后，您可以从文件中读取行，并将它们添加到
StringBuilder使用
Reader：
//The buffered reader has a method readLine() that reads an entire line from the file, InputStreamReader is a reader that reads from a stream.BufferedReader reader = new BufferedReader(new InputStreamReader(in));//This is the StringBuilder that we will add the lines to:StringBuilder sb = new StringBuilder(512);String line;//While we can read a line, append it to the StringBuilder:while((line = reader.readLine()) != null){ sb.append(line);}//Close the stream:reader.close();//and return the result:return sb.toString();
