I have a TextView which contains text with Html attributes like subscription,
for example it's a chemical formula H2SO4. How can I get this text from textview, but with subscriptions (String isn't showing the subscript)
here you can see screenshot
https://www.dropbox.com/s/0u9vtmqaxdnqfy5/Capture.PNG
To set H2SO4 in textview,Use subscript tag as
textview.setText(Html.fromHtml("H<sub>2</sub>SO<sub>4</sub>"), TextView.BufferType.EDITABLE);
where textview is your Textview's tag.
And get text from textview as
String str = Html.toHtml(textview.getEditableText()).toString();
anothertextview.setText(Html.fromHtml(str));

I have a StringBuffer with a HTML Site in it and want to have some specific information of this Site.
1 line is f.e.:
img class="a" data-src="http://test.com" src="" /<
and i want a String with "http://test.com".
Is there a function/parser which can help me?
This is a common question and you could've found the answer with a quick Google search.
Look into Regular Expression (regex) as you'll need it probably more than once.
Consider JSoup framework.
There is "Selector" mechanism to find and operate with html elements.
Jsoup will do the trick, just do a little css and you can get whatever element you need.
Document doc = Jsoup.connect("http://test.com").get();
//DOM Selector CSS String see jsoup docs.
//This will select all image elements with the a class similar to css. IE: img.a
//http://jsoup.org/cookbook/extracting-data/selector-syntax
//Get all elements that are images with class of a
Elements images = doc.select("img.a");
for (Element image : images) {
//Get the url of the image
String url = image.attr("data-src");;
}

Is there any simple library in java which can parse a string as input and produce result after evaluating the input string.
Such as- I will give a String like 5+5*(4/2)-7+1
and any of the library method will return me the output: 9.
Java provides a built-in JavaScript syntax processing:
javax.script.ScriptEngineManager mgr = new javax.script.ScriptEngineManager();
javax.script.ScriptEngine engine = mgr.getEngineByName("JavaScript");
String res = "5+5*(4/2)-7+1";
System.out.println(engine.eval(res));

java.awt.Color has a couple of defined Colors - for example, Color.RED (or Color.red) is a public static value that returns Color(255, 0, 0). But there are only a limited set of colors defined - 13 by my count.
Are there any Java libraries that have the HTML Color Chart colors defined, so I can say something like ColorLibrary.AQUAMARINE and get back #60CC93? Or, even better, are there libraries that map the name to the color, so I can say Color color = ColorMap.get("aquamarine");?
There aren't many libraries which have compiled a map of colour names to rgb/hex values, however there are a few different libraries which provide functions to get colours which are predefined by java.

I have a textarea in my webpage works as a editor.
While typing the java/c/c++ code in the textarea, I want the code to be formatted and auto beautify itself (like coloring keywords, spaces, auto tabs for code inside {} blocks).
Or
I need an editor which can be embedded in my webpage.
You can use CodeMirror (C, C++ and Java example there : http://codemirror.net/mode/clike/index.html)
It's really simple to make it work, just include codemirror.js, codemirror.css and the .js of the languages you want in your page's header, then there is a method to create an editor from a textarea, for instance :
CodeMirror.fromTextArea(document.getElementById("TEXTAREA_ID"), {
mode: "text/x-java",
indentWithTabs: true,
smartIndent: true,
lineNumbers: true,
lineWrapping: true,
matchBrackets : true,
autofocus: true
});
More infos : http://codemirror.net/doc/manual.html
Of course there are others (Ace, EditArea, ...) but I already used that one and I'm happy with it :)
Cheers

I'm looking for an api/method/framework where I can compare strings. One is a string stored on the server whereas the other is a string given by user input.
For example:
Stored String : "Login"
User input : "login" "log in" "lOG IN" or any such permutation.
I'm using java in spring mvc (making a webapp). the server is getting a string from the user and then looks for a string similar to the given string and returns the found records.
Any help would be appreciated. Thanks
Unless your data size is small (< a few MB), you probably want something like Apache Lucene, which can be used to index and search large document sets, and can do fuzzy searches using Levenshtein distance and other algorithms for similarity matches.
