读取保留以前格式的文本文件

Question

我正在创建一个简单的网络应用程序，并希望在启动时加载聊天记录，这可以正常工作，但它将文本格式化为一行

写入档案

CharSequence cs = tv.getText ();
final String str = cs + "\r\n" + s;
//Write to text file
try {
FileOutputStream fos = openFileOutput("Chat Log", Context.MODE_APPEND);
fos.write(s.getBytes());
fos.close();
} catch (Exception e) {
e.printStackTrace();
}



}
catch (IOException e1)
{

e1.printStackTrace();
}
//close the socket
socket.close(); 

阅读文字

final TextView tv = (TextView)findViewById(R.id.textView1);
try {
BufferedReader inputReader = new BufferedReader(new InputStreamReader(
openFileInput("Chat Log")));
String inputString;
StringBuffer stringBuffer = new StringBuffer();
while ((inputString = inputReader.readLine()) != null) {
stringBuffer.append(inputString + "\r\n");
tv.append(inputString);
}

} catch (IOException e) {
e.printStackTrace();
}

您应该可以使用Html.toHtml和Html.fromHtml保存格式。

有些事情：

{
  "_index" : "logstash-2016.04.21",
  "level1" : {
    "level2" : {
      "1" : "somevalue",
      "2" : "somevalue2"
    }
  }
}

然后：

String htmlFormatted = Html.toHtml(tv.getText());
// .. save to file ..
