Remove part of String Android

Question

in my app I get a String from RSS fedd item(tag description)and put it in a ListView but the String looks like this:

I try to remove the tag with this method but doesn't work:

private String refactor(String mess) {
        int indexToRemove = mess.lastIndexOf("<strong>");
        String toBeReplaced = mess;
        if(indexToRemove >= 0 ){
             toBeReplaced = mess.substring(0, indexToRemove);
        }
        int newIndex = toBeReplaced.lastIndexOf("</strong>");
        String messFinal = toBeReplaced;
        if(newIndex >= 0){
            messFinal = toBeReplaced.substring(0, newIndex);
        }
        return messFinal;
    }

Answer 1

Would be better to not to remove HTML tags, but render them correctly.

textView.setText(Html.fromHtml(sourceString));

Answer 2

Why don't just use replace() from String?

If you want render the HTML correctly you could just use

Spanned parsedHtmlString = Html.fromHtml(htmlString)

instaed if rendering the html can cause you some layout problems you can use this to remove the html tags

Spanned strippedHtmlString = Html.fromHtml(htmlString).toString()

Remember that those metdods are deprecated starting from Android N, so you need to use something like this for compiling with API 24+

Spanned result;

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
    result = Html.fromHtml(htmlString, Html.FROM_HTML_MODE_LEGACY); //add .toString() to remove html tags
} else {
    result = Html.fromHtml(htmlString); //add .toString() to remove html tags
}

took from here

EDIT Based on your comment, i think you should go with this:

public RssItem(Parcel source) { 
    Bundle data = source.readBundle();
    title = Html.fromHtml(data.getString("title")).toString(); 
    link = Html.fromHtml(data.getString("link")).toString(); 
    pubDate = (Date) data.getSerializable("pubDate"); 
    description = Html.fromHtml(data.getString("description")).toString(); 
    content = Html.fromHtml(data.getString("content")).toString(); 
    feed = data.getParcelable("feed"); 
}

i've omitted some objects because it really depends on what they contain. Moreover you should do some check for null before parsing them with Html.fromHtml

You can use Jsoup for removing html tags.

private String refactor(String html) {
    return Jsoup.parse(html).text();
}
