How to split string in android

Suppose i have a String, below
String myText="I'm a android developer and i'm developing an android app";
so i want to split the above string with(" ' "), and want to put it on a textView so how it is possible. i have used this code
split(Pattern.quote("'"));
so my complete code is :
textUser.setText(User);
String[] newDesc=Description1.split(Pattern.quote("'"));
for(String w:newDesc){
textDesc.setText(w);
}
but this is not working. Please resolve my issue

I believe Pattern.quote() wrapps your RegExp so that it only works if the matching string in inside quotes.
In other words, I do not believe in this case it would work.
A simple String[] newDesc=Description1.split("'"); should work.

Use this please
String[] newDesc=Description1.split("'");

Use the below code to understand the split string you need:
Example : String myText = "I'm a android developer and i'm developing an android app";
String[] strParts = myText.split("'");
Then
String strFirstString = strParts[0]; // I
String strSecondString = strParts[1]; // m a android developer and i
String strThirdString = strParts[2]; // m developing an android
Now display whichever String you want, in your textView.

Parsing a string?

So I have the following string:
String text = "\t\t\torder #168\n\t\t\tpaid\n\t\t\tview 4 items\n\t\t\tpicked up\n\t\t\tcomplete pickup\n\t\t\t2 stops";
How do I parse this string so that I always get the 2 in front of stops? I have tried the following, but it always returns 2 stops.
String substr = "complete pickup";
String numberOfStops = text.substring(text.indexOf(substr) + substr.length());
numberOfStops = numberOfStops.replaceAll("^\\s+","").replaceAll("\\s+$","");

The short way:
numberOfStops = numberOfStops.replaceAll("^\\s+","").replaceAll("\\s+$","").replace("stops","");
The flexible way is using Regex, and Pattern and Match classes. Let me know if you need it

SKipping image while converting html text to string android

Iam converting some Html text from a webpage into a String by doing the following
mydescription =Html.fromHtml(data.getBody()).toString();
This is what data.getBody() returns:-
<div><p>​It's great to have great dynamic companies to work with, and NXP is no exception.</p><p><img alt="This is an image of NXP Logo" src="https://anprodstorage.blob.core.windows.net/b75ef288-0381-45c4-a4cd-809097370bec/untitled.png" style="margin:5px;" /><br></p><div><iframe width="560" height="315" src="https://www.youtube.com/embed/I6191gXXGog" frameborder="0"></iframe> </div><p>​<br></p></div>
But within that html text there is a image source as well. When I do the above I get a square image with obj written inside it instead of the image.
This is myDescription

I just want to get the text and not the image.
How do i just get the text and not the image

Try this way,hope this will help you to solve your problem.
String htmlString = "<div><p>​It's great to have great dynamic companies to work with, and NXP is no exception.</p><p><img alt=\"This is an image of NXP Logo\" src=\"https://anprodstorage.blob.core.windows.net/b75ef288-0381-45c4-a4cd-809097370bec/untitled.png\" style=\"margin:5px;\" /><br></p><div><iframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/I6191gXXGog\" frameborder=\"0\"></iframe> </div><p>​<br></p></div>";
String first = htmlString.substring(0,htmlString.indexOf("<img"));
String second = htmlString.substring(htmlString.indexOf("/>",htmlString.indexOf("<img"))+2,htmlString.length());
textview.setText(Html.fromHtml(first+second));

use this code:
String clippedBody = htmlString.replaceAll("<img[^>]*?>.*?/[^>]*?>", "");

I advise using libraries, like jsoup when working with HTML (with soup you will be able to get only text by calling Jsoup.parse(html).text())
Haven't tried it myself
private static final Pattern REMOVE_TAGS = Pattern.compile("<img>(\\S+)</img>");
public static String removeTags(String string) {
if (string == null || string.length() == 0) {
return string;
}
Matcher m = REMOVE_TAGS.matcher(string);
return m.replaceAll("");
}
If you want to strip down all the HTML code, then you can use:
replaceAll("\\<[^>]*>","")
For your second question (from Source 2):
// the pattern we want to search for
Pattern p = Pattern.compile("<p>(\\S+)</p>");
Matcher m = p.matcher(string);
// if we find a match, get the group
if (m.find())
{
// get the matching group
String codeGroup = m.group(1);
// print the group
System.out.format("'%s'\n", codeGroup);
}

Android: String replace("<\" , "<") returns error

I need to replace all the <\ symbols with < in a HTML String retrieved using JSON.
Apparently,
String correctText = TEXT.replace("<\" , "<");
cannot be performed because the first expression is recognized as an exit statement instead of a Char sequence.
How can I do this?

try this:
String correctText = TEXT.replace("<\\" , "<");

Removing space from Edit Text String

In my android app, I am getting the String from an Edit Text and using it as a parameter to call a web service and fetch JSON data.
Now, the method I use for getting the String value from Edit Text is like this :
final EditText edittext = (EditText) findViewById(R.id.search);
String k = edittext.getText().toString();
Now normally it works fine, but if we the text in Edit Text contains space then my app crashes.
for eg. - if someone types "food" in the Edit Text Box, then it's OK
but if somebody types "Indian food" it crashes.
How to remove spaces and get just the String ?

Isn't that just Java?
String k = edittext.getText().toString().replace(" ", "");

try this...
final EditText edittext = (EditText) findViewById(R.id.search);
String k = edittext.getText().toString();
String newData = k.replaceAll(" ", "%20");
and use "newData"

String email=recEmail.getText().toString().trim();
String password=recPassword.getText().toString().trim();
In the future, I highly recommend checking the Java String methods in the API. It's a lifeline to getting the most out of your Java environment.

You can easily remove all white spaces using something like this. But you'll face another serious problem if you just do that. For example if you have input
String input1 = "aa bb cc"; // output aabbcc
String input2 = "a abbcc"; // output aabbcc
String input3 = "aabb cc"; // output aabbcc
One solution will be to fix your application to accept white spaces in input string or use some other literal to replace the white spaces. If you are using only alphanumeric values you do something like this
String input1 = "aa bb cc"; // aa_bb_cc
String input2 = "a abbcc"; //a_abbcc
String input3 = "aabb cc"; //aabb_cc
And after all if you are don' caring about the loose of information you can use any approach you want.
