Android TextView not showing multiple lines, even though String has newlines [duplicate]

For the input text:
<p>Arbit string <b>of</b><br><br>text. <em>What</em> to <strong>do</strong> with it?
I run the following code:
Whitelist list = Whitelist.simpleText().addTags("br");
// Some other code...
// plaintext is the string shown above
retVal = Jsoup.clean(plaintext, StringUtils.EMPTY, list,
new Document.OutputSettings().prettyPrint(false));
I get the output:
Arbit string <b>of</b>
text. <em>What</em> to <strong>do</strong> with it?
I don't want Jsoup to convert the <br> tags to line breaks, I want to keep them as-is. How can I do that?

Try this:
Document doc2deal = Jsoup.parse(inputText);
doc2deal.select("br").append("br"); //or append("<br>")

This is not reproducible for me. Using Jsoup 1.8.3 and this code:
String html = "<p>Arbit string <b>of</b><br><br>text. <em>What</em> to <strong>do</strong> with it?";
String cleaned = Jsoup.clean(html,
"",
Whitelist.simpleText().addTags("br"),
new Document.OutputSettings().prettyPrint(false));
System.out.println(cleaned);
I get the following output:
Arbit string <b>of</b><br><br>text. <em>What</em> to <strong>do</strong> with it?
Your problem must be somewhere else I guess.

Extra line breaks at end of text

I seem to be getting what seems like some extra line breaks after using this method to set the text of a TextView
message.setText(Html.fromHtml( message ));
How can I remove these? They cause my layout to get warped since it adds two extra lines to the output.
The string was saved to my sqlite database via Html.toHtml( editText.getText() ).trim();
Initial string input : hello
Log output of the message variable: <p dir="ltr">hello</p>

you can use this lines ... totally works ;)
i know your problem solved but maybe some one find this useful .
try{
string= replceLast(string,"<p dir=\"ltr\">", "");
string=replceLast(string,"</p>", "");
}catch (Exception e) {}
and here is replaceLast ...
public String replceLast(String yourString, String frist,String second)
{
StringBuilder b = new StringBuilder(yourString);
b.replace(yourString.lastIndexOf(frist), yourString.lastIndexOf(frist)+frist.length(),second );
return b.toString();
}

For kotlin you can use
html.trim('\n')

Looks like toHtml assumes everything should be in a <p> tag. I'd strip off the beginning and ending <p> and </p> tags before writing to the database.

This is working as below in Kotlin.
val myHtmlString = "<p>Test<\/p>"
HtmlCompat.fromHtml(myHtmlString.trim(), FROM_HTML_MODE_COMPACT).trim('\n')

Android Remove First and Last <div> tag from html text using Jsoup

I want to remove first and last div tag from the html text. i use jsoup library to parse the html text.i tried some thing which are shown in code.The html text which have more than one div tag or not be , but i want to remove just first and last div tag if available. please help me. thanks in advance.
public String divremove(String html) {
Document doc = Jsoup.parse(html);
for (Element e : doc.select("div")){
if (e != null) {
Log.e("LOG","link >> " + e.text());
}
}
/* Element link = doc.removeClass("div");
if (link != null)
{
}
Integer in = doc.select("div").first().elementSiblingIndex();*/
Element link = doc.select("div").first();
Log.e("LOG","link >> " + link);
Element link2 = doc.select("div").last();
Log.e("LOG","link2 >> " + link2.text());
return html;//formatted
}

Here's an example:
final String html = "<div>A</div><div>B</div><div>C</div><div>D</div>";
Document doc = Jsoup.parse(html);
// (1) - Remove from html
doc.select("div").first().remove();
doc.select("div").last().remove();
System.out.println(doc.body());
// (2) - Remove from list
Elements divs = doc.select("div");
divs.remove(0);
divs.remove(divs.size()-1);
System.out.println(divs);
(1) removes the first and last tag from the html, so doc wont contain them anymore. If you just want to remove them from your selected div's, use (2) instead. This will keep it in your html (= doc), but it's removed from divs.

Android, how to replace slashes in path

i have an image path : "UploadFile\\/UserProfile\\/Female.jpg". How to replace "\\/" with "/"?
i have tried :
replaceAll("\\/","/")
replaceAll("\\\\/","/")
Code:
adapter_profilepic = objUser.getProfilePicture().replaceAll("\\/","/");

This works :
String src = "UploadFile\\/UserProfile\\/Female.jpg";
src = src.replaceAll("\\\\/","/");
System.out.println(src);
output:
UploadFile/UserProfile/Female.jpg
You said you tried it, but check it again.

According documentation your string is used as regular expression. Why you don't using replace:
String adapter_profilepic = objUser.getProfilePicture().replace("\\\\/","/");

Android Jsoup in service - get text of span

Im pretty new to jsoup. For days im trying now to read out a simple number from a span without any success.
I hope to find help here. My html:
<div class="navi">
<div class="tab mail">
<a href="/comm.php/indexNew/" accesskey="8" title="Messages">
<span class="tabCount">1 </span>
<img src="/b2/message.png" alt="Messages" class="moIcon i24" />
</a>
</div>
The class tabCount excists 3 times though in the whole document and I am interested in the first span with this class.
Now I am trying in onCreate() of a service to create a thread with:
Thread downloadThread = new Thread() {
public void run() {
Document doc;
try {
doc = Jsoup.connect("https://www.bla.com").get();
String count = doc.select("div.navi").select("div.tab.mail").select("a[href]").first().select("tabCount").text();
Log.d("SOMETHING", "test"+(count));
} catch (IOException e) {
e.printStackTrace();
}
}
};
downloadThread.start();
This forces my app to crash. The same if i change text() to ownText(). if i remove text() then the app can start but it gives me null.
what am i doing wrong? By the way, besides the service a webview is loading the same url. might that be a problem?

You only need to select the element you're interested in, you don't need to get every outer element before. In your example you could try
String count = doc.select("span.tabCount").text();
Where you define the type of the element "span" and class name ".tabcount"
For an example that might help you, look at this link
Edit:
Try this code instead, this will get the value of the first span.
Elements elements = doc.select("span.tabCount");
String count = elements.first().text();
And if you want to print all elements you could do like this.
Elements elements = doc.select("span.tabCount");
for (Element e : elements) {
Log.d("Something", e.text();
}

Haven't you meant .select(".tabCount")?
BTW, on Android AsyncTasks are more convenient than Threads. Also, empty catch blocks are a bad practice.

Your select statement is wrong. You can insert the whole selection string in one line. Furthermore you have to prefix "tabCount" with a dot as it is a class.
String count = doc.select("div.navi div.tab.mail a").first().select(".tabCount").text();
