Alternative for String.join in Android?
Question
I want to concatenate an ArrayList with commas as separators. I found this answer , stating it's possible to use String.join in Java.
When I try to use this however, Android Studio gives the following error:
Cannot resolve method 'join(java.lang.String, java.lang.String, java.lang.String, java.lang.String)'
Is there a good, concise alternative for Android Studio (instead of using a for loop)?

You can use TextUtils.join instead:
String result = TextUtils.join(", ", list);
( String.join was added in Java 8, which is why you can't use it in Android.)

String[] List ={"<html>","<body>","<title>"};
String abc;
abc =TextUtils.join("\n", List);
textmsg.getText().insert(textmsg.getSelectionStart(), abc);
result:
<html> <body> <title>

你可以用它
TextUtils.join(", ", your_list);
