java – Android Split string

Posted by: admin March 10, 2020 Leave a comment

Questions:

I have a string called CurrentString and is in the form of something like this
"Fruit: they taste good".
I would like to split up the CurrentString using the : as the delimiter.
So that way the word "Fruit" will be split into its own string and "they taste good" will be another string.
And then i would simply like to use SetText() of 2 different TextViews to display that string.

What would be the best way to approach this?

How to&Answers:
String currentString = "Fruit: they taste good";
String[] separated = currentString.split(":");
separated[0]; // this will contain "Fruit"
separated[1]; // this will contain " they taste good"

You may want to remove the space to the second String:

separated[1] = separated[1].trim();

If you want to split the string with a special character like dot(.) you should use escape character \ before the dot

Example:

String currentString = "Fruit: they taste good.very nice actually";
String[] separated = currentString.split("\.");
separated[0]; // this will contain "Fruit: they taste good"
separated[1]; // this will contain "very nice actually"

There are other ways to do it. For instance, you can use the StringTokenizer class (from java.util):

StringTokenizer tokens = new StringTokenizer(currentString, ":");
String first = tokens.nextToken();// this will contain "Fruit"
String second = tokens.nextToken();// this will contain " they taste good"
// in the case above I assumed the string has always that syntax (foo: bar)
// but you may want to check if there are tokens or not using the hasMoreTokens method

Answer:

.split method will work, but it uses regular expressions. In this example it would be (to steal from Cristian):

String[] separated = CurrentString.split("\:");
separated[0]; // this will contain "Fruit"
separated[1]; // this will contain " they taste good"

Android split not working correctly

Answer:

android split string by comma

String data = "1,Diego Maradona,Footballer,Argentina";
String[] items = data.split(",");
for (String item : items)
{
    System.out.println("item = " + item);
}

Answer:

     String s = "having Community Portal|Help Desk|Local Embassy|Reference Desk|Site News";
     StringTokenizer st = new StringTokenizer(s, "|");
        String community = st.nextToken();
        String helpDesk = st.nextToken(); 
        String localEmbassy = st.nextToken();
        String referenceDesk = st.nextToken();
        String siteNews = st.nextToken();

Answer:

You might also want to consider the Android specific TextUtils.split() method.

The difference between TextUtils.split() and String.split() is documented with TextUtils.split():

String.split() returns [”] when the string to be split is empty. This returns []. This does not remove any empty strings from the result.

I find this a more natural behavior. In essence TextUtils.split() is just a thin wrapper for String.split(), dealing specifically with the empty-string case. The code for the method is actually quite simple.
