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?
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
etPhoneNo.getText().toString().replaceAll("\\D", ""); its says that replace all which is not digit.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"
Also, this came from: Android split not working correctly
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);
}
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();
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.
