Question

我需要显示一个包含很多新行'\ n'的字符串。这些字符串需要替换为该字符串中的实际换行符。我怎么能在android中做到这一点？

Answer 1

你可以使用它..

StringWriter stringWriter = new StringWriter();
PrintWriter writer = new PrintWriter(stringWriter, true);
writer.println("line1");
writer.println("line2");
writer.println("line3");
useString(stringWriter.toString());

line1, line2 and line3将分开打印。

Answer 2

String myString = "lots of \n new \n lines";
String newStringWithoutNewLines = myString.replace("\n", "");

Answer 3

你应该连接新行操作符，如：

String str = "This is testing" + "\n" + "How are you?";

你在数据库中说过，你可以分开：

String[] separated = str.split("\n");
separated[0]; // this will contain "This is testing"
separated[1]; // this will contain "How are you?"

然后将它们连接起来

Answer 4

似乎正在发生的事情是，您从数据库收到的字符串不包含换行符，而是包含字符\和n。最简单的解决方法是使用String.replace函数将字符序列\ n替换为字符\n，如下所示：

String str = getStringWithFakeNewlines();
str.replace("\\n", "\n"); // The first backslash is doubled to find actual backslashes

如何用android中的字符串中的实际新行替换换行符？
