It's fine? :D
I have an API PHP that receives html text replaced by string [tag] tags and my Android app needs to replace this tags of text by Spannable strings.
I have a problem with replace string tags of [strong], [br], [p], [i] to SpannableString and to apprimorate the content text.
Not all text is overwritten correctly. Some [strong] tags, for example, still remain there, other times the text is repeated, rather than overlapping.
My Activity receives that:
...
SpannableStringBuilder parseContent = new StringTagParserHelper(tagPost.getContent())
.addMultipleStyle();
contentView.setText(parseContent);
My String parser classe is:
public class StringTagParserHelper {
private static String rawText;
private SpannableStringBuilder spannableContent;
public StringTagParserHelper(String text) {
rawText = text;
}
/**
* @return
*/
public SpannableStringBuilder addMultipleStyle() {
spannableContent = new SpannableStringBuilder(rawText);
cleanTags("strong");
return spannableContent;
}
private void cleanTags(String tag) {
Pattern pattern = Pattern.compile(tag + "\\](.+?)\\[/" + tag);
Matcher matcher = pattern.matcher(rawText);
while (matcher.find()) {
Log.d("PARSE", String.valueOf(matcher.group(1)));
String _internal = matcher.group(1);
int start = matcher.start();
int end = matcher.end();
if (tag.equals("strong")) {
Spannable spanText = new SpannableString(_internal);
spanText.setSpan(
new StyleSpan(Typeface.BOLD), 0, _internal.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
);
spannableContent.replace(start, end, spanText);
}
if (tag.equals("br")) {
//
}
}
}
.
[EDIT]
Added 2 screenshots.
- One with bold text and spannable replace of
spanText
- another without style and spannable replace
_internalstring.
The line of Log.d() receives the list of raw string text without tags.
Log.d("PARSE", String.valueOf(matcher.group(1)));
Please, help me, guys!
