android开发打开文件txt并返回内容

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();
