AlertDialog message with new line. (\n doesn't work.)

问题

I need to use a break-line in a AlertDialog on Android. I already tried with the "\n" character but it doesn't work. I don't see the "\n" character but the text wont wrap.

Any help?

回答1:

You can use Spanned text using Html.fromHtml("some string" + "<br>") to create new line on some textview element.

回答2:

If you are receiving the String from somewhere, maybe the \n is being escaped.

Try with:

string = string.replace("\\n","\n");

回答3:

How about using the HTML tag to set new text?

    controlName.setText(Html.fromHtml(outputString + "<br/>" + outputString2));

回答4:

It doesn't matter when use "\n" in Dialog or Activity/Fragment.
I faced the same issue but it turned out the TextView have the attribute: android:singleLine="true" or android:maxLines="1", it conflicts with "\n" so make sure to REMOVE these attributes first.
