How do I set phone numbers to be LTR in a RTL TextView with RTL characters

As you can see here, the phone number here is starting from the right to the left.
However, I want it to display it like this (Image here is edited):
This is the TextView displaying this message:
<TextView
android:text="#string/smsSentTo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/smsSentTo"
android:textColor="#color/mdtp_white"
android:textSize="18sp"
android:layout_above="#+id/chooseUsernameAndPickProfilePicture"
android:layout_centerHorizontal="true"
android:layout_marginBottom="24dp"/>
#string/smsSentTo (Arabic locale): (looks like StackOverflow is displaying the {0} wrong, ignore that.)
<string name="smsSentTo">تم إرسال رسالة SMS إلى {0}</string>
#string/smsSentTo (English locale):
<string name="smsSentTo">An SMS has been sent to {0}</string>
As you can see, I'm formatting the text using MessageFormat:
String smsSentTo = MessageFormat.format(smsSentToTV.getText().toString(), phone);
smsSentToTV.setText(smsSentTo);
How can I get it to display these properly?

There is a solution with a downside
String html = "<p>تم إرسال رسالة SMS إلي</p>" + "+961 01 234 567";
textView.setText(Html.fromHtml(html));
The downside is that the HTML p tag prints a line afterwards separating the number into the next line. I tried to remove it with some HTML attributes or using tags other than p tag, but that didn't work
Hope this satisfies your need, or can give you even a clue.

HTML with sub and sub-sub bullets not showing properly

Consider this HTML:
<ul>
<li>Some bullet point text.</li>
<li>Another bullet point:</li>
<ul>
<li>A Sub Bullet point of the above.</li>
<ul>
<li>A Sub sub bullet point.</li>
</ul>
<li>The second sub bullet point.</li>
</ul>
</ul>
I'm loading this into a TextView in MainActivity:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val someText = findViewById<TextView>(R.id.someTextView)
val url = "<ul>\n" +
" <li>Some bullet point text.</li>\n" +
" <li>Another bullet point:</li>\n" +
" <ul>\n" +
" <li>A Sub Bullet point of the above.</li>\n" +
" <ul>\n" +
" <li>A Sub sub bullet point.</li>\n" +
" </ul>\n" +
" <li>The second sub bullet point.</li>\n" +
" </ul>\n" +
"</ul>\n"
someText.text = Html.fromHtml(url, Html.TO_HTML_PARAGRAPH_LINES_CONSECUTIVE)
}
Nothing special with the activity_main.xml:
<TextView
android:id="#+id/someTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
Expected (Sub, Sub-sub bullet points):
Actual (no sub and sub-sub bullets AND indenting is wrong):
I've tried this library but it has the same problems.
Another solution would be to convert the tags to "\u25CF" and sub-sub bullets to "\u25CB" (or BulletSpan) and use JSoup for the ordering. But this feels like a lot of work for a standard HTML text.
I've tried MyTagHandler but the same problem.
Any ideas?
Thanks for the help guys!

ul and li tags are not supported by Html.fromHtml() method. There is an open issue in Google Issue Tracker about these missing tag supports and about the supported tags not listen on Html.fromHtml() method's documentation.
But, I think BulletSpan might be helpful.

How to differentiate two HTML elements with the same class?

I would like to know if there is any method in Jsoup that differentiates multiple elements with the same class. For clarification, consider the following HTML fragment, I need to retrieve the class name "description", but I need to differentiate one information from the other.
<Div class = "related-box gray-text no-margin">
<H3 class = "epsilon"> Awards </ h3>
<P class = "description">
<Strong> Sena - 6 </ strong> <br>
There was no
</ P>
<P class = "description">
<Strong> Quina - 5 </ strong> <br>
124 winning bets, R $ 43,174.39
</ P>
<P class = "description">
<Strong> Quadra - 4 </ strong> <br>
8817 winning bets,
</ P>
Thank You!

Assuming you want to grab the second <p>tag in the posted div, you have multiple options. The following examples use the nth-of-type CSS selector, the get function for jsoup Elements (inherited from ArrayList) and iterating through the elements, if you need more detailed comparison of the elements contents. There are a lot more options and as mentioned in my comment above, using tools like the chrome developer tools, you can select elements and get a matching selector, which might be a good starting point for generalization.
Example Code
String source ="<div class='related-box gray-text no-margin'>"+
"<h3 class='epsilon'>Awards</h3>"
+ "<p class='description'><strong>Sena - 6</strong><br>There was no</p>"
+ "<p class='description'><strong>Quina - 5</strong><br>124 winning bets, R $ 43,174.39</p>"
+ "<p class='description'><strong>Quadra - 4</strong><br>8817 winning bets,</p></div>";
Document doc = Jsoup.parse(source, "UTF-8");
// nth-of-type(n) CSS selector
Element quina = doc.select(".description:nth-of-type(2)").first();
System.out.println(quina.text());
// Elements.get(n) jsoup method
quina = doc.select(".description").get(1);
System.out.println(quina.text());
// iterate over Elements
Elements descriptions = doc.select(".description");
for (Element element : descriptions) {
if(element.text().contains("Quina")){
quina = element;
}
}
System.out.println(quina.text());
Output
Quina - 5 124 winning bets, R $ 43,174.39
Quina - 5 124 winning bets, R $ 43,174.39
Quina - 5 124 winning bets, R $ 43,174.39

how to fetch raw() function enabled content using json in ruby on rails

I have one rails application where I have one model posts. Post model having two attributes - "title" & "content". I am using ckeditor for my content. Here is my ckditor snapshot
When I save something eg- "hi how r u" with bold, itallic, underline etc. Then it save posts content like this <b><i><u>hi how r u</u><i></b>. I know the solution in rails. I am using <%= raw(#posts.content) %> to solve this problem. But Now my problem is different. I want to fetch all the posts content from the database by using json. I am doing like this..
def index
#posts = Post.all
respond_with(#posts) do |format|
format.json { render json: #post_names = {:post => #posts.as_json(:only=> :content)} }
end
end
Now when i go through http://localhost:3000/posts.json then it showing like this
{"post":[{"content":"hi"},{"content":"hi"},{"content":"<img src=\"https://www.ginfy.com/img/logo.png\">"},{"content":"hi"},{"content":"my health is not good. Please pray for me..<br>"},{"content":"my health is not good. Please pray for me<br>"},{"content":"hello"},{"content":"<img src=\"http://www.ibettertechnologies.com/img/logo.png\">"},{"content":"<u><i><b>hi how r u?</b></i></u><br>"},{"content":"sdfsd"},{"content":"i am going to home. Please pray for my safe jouney"},{"content":"job"},{"content":"dsfdfs"},{"content":"fddf"},{"content":"jd dsbdsj djhj dsjhdfjks"},{"content":"ddd gd fgdfdg"},{"content":"dfslkdfskldfskl dskljdfskldf dskljdfskldfjslk"},{"content":"please pray for me"},{"content":"dfdf"},{"content":"cvxvxdfs"},{"content":"hdbhjds dsjks"},{"content":"s"},{"content":"hi"},{"content":"hu"}]}
I want to fetch this json in android. How can I use <%= raw() %> function in json to get correct formatted value.

You have to use Html.fromHtml() function to escape HTML tags. You can do like this ..
<TextView
android:id="#+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_margin="5dp"
android:textColor="#android:color/black"
android:textSize="20sp"
android:textStyle="bold" />
text2.setText(Html.fromHtml(app.getTitle()).toString());

Parsing issues while parsing xml response android

Xml response is like , but in one tag , the text is this:
<Description>
<center><strong><span>Warehouse / Building Maintenance</span></strong></center><br />
<br />
<strong><span>I</span></strong><span>mmediate openings available in the local Perris area for warehouse/building building maintenance positions. <br />
<br />
<strong>Job Description:</strong><br />
</span>
<ul>
<li><span>Associates will be responsible to define pieces of equipment that will paralyze operations if they fail, and plan whatever level of preventative maintenance necessary. <br />
</span></li>
<li><span&gt
......
similar text
......
</Description>
I can't able to parse it in proper way.
I tried using Jsoup.parse((nodeValue))
and Html.fromHtml(String) also URLEncoder.encode(String)
but its returning simple & symbol thats it.
How to parse this type of response?

A temporary solution could be applying replaceAll("<", "<").replaceAll(">", ">") if API methods aren't working, but arent you supposed to use Html.toHtml(string) when you have stuff encoded and want it to become real html ?

Actually its returning only & symbol , that's because the nodelist item returns only single value.
After using like this:
NodeList fstNm = fstNmElmnt.getChildNodes();
System.out.println("nodefstnm"+fstNm.getLength());
for(int j=0;j<fstNm.getLength();j++) {
String val = ((Node) fstNm.item(j)).getNodeValue();
nodeValue=nodeValue.concat(val);
}
and then parsing with Jsoup., returns what I want.
