英文:

Setting a new line from API call not creating newline

问题

设置新行而不进行网络调用对我有效：

mTextView.setText("Message 1 \nMessage 2");

[![enter image description here][1]][1]

但是当我从API调用中的JSON设置文本时，它对我不起作用：

mTextView.setText(userInfo.getDescription());

[![enter image description here][2]][2]

它在我的数据库中存储的格式是：hello \nTest message.

问题是什么？

编辑：

尝试这样做，但也不起作用

String x = description.replace("\n", System.lineSeparator());
Log.d(TAG, "formatDescription: Formatted: " + x);
return x;```

编辑2：

需要在``` .replace("\n", System.lineSeparator());``` 中添加额外的```"\"```才能使其起作用

Setting a new line without a network call works for me:

```mTextView.setText(&quot;Message 1 \nMessage 2&quot;);```

However when I set the text from the JSON in an API call it doesn&#39;t work for me:

```mTextView.setText(userInfo.getDescription());```

[![enter image description here][2]][2]

The format it&#39;s stored in my db is: ```hello \nTest message.```


What is the issue?

Edit: 

Tried doing this, but doesn&#39;t work either

Log.d(TAG, "formatDescription: Description: " + description);
String x = description.replace("\n", System.lineSeparator());
Log.d(TAG, "formatDescription: Formatted: " + x);
return x;

Edit 2: 

Need to add an extra ```"\"``` to ```.replace("\n", System.lineSeparator());``` for it to work
