I have the following problem
I have some text that will be inserted by the user and we will take as an example
Implemented phrase: I would like to know how to program better #hoje.
I wanted to loop through words beginning with # a listview underneath these words (ex: #hoje) and that these should be replaced by suggestions in this listview?
How do I? Thank you in advance.
By using the tag regex I believe your difficulty is to change the #nome of the string, in your case I think this will solve:
foobar.replaceAll("(^|\s)#hoje($|\s)", "$1" + valorAtual + "$2");
Note: I tested
\binstead of(^|\s)and($|\s), but I do not know why it did not work.
In a simple example it would look something like:
final String frasePadrao = "Eu gostaria de saber programar melhor #hoje";
final String fraseRegex = "(^|\s)#hoje($|\s)";
listView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<String>()
{
@Override
public void changed(ObservableValue<? extends String> observable, String valorAntigo, String valorAtual)
{
minhaLabel.setText(
frasePadrao.replaceAll(fraseRegex, "$1" + valorAtual + "$2")
);
}
});
minhaLabelwould be a label where text appears
(^|\s) search for space or beginning of string #hoje fetches the word you'd like to be replaced ($|\s) search space or end of string That is, in this way you can write #hoje to any position in the string, avoiding conflict with other texts that could vary. Technically \b should resolve this from the spaces between the word, but I do not know if it's a Java behavior, it just does not work:
"\b#hoje\b"
In other languages I had no problem using \b . However, (^|\s) and ($|\s) already meet this
