Programming in Android, most of the text values are expected in CharSequence.
Why is that ? What is the benefit and what are the main impacts of using CharSequence over String ?
What are the main differences, and what issues are expected, while using them, and converting from one to another ?

I'm looking for a way to convert a string to a charsequence.
My code is:
Code:
public void randText(int r){
r++; //necessary increment
String rs = Integer.toString(r); //random string[code]....
The random int r is created outside the method. This method gives a random string, from my resource file. All of the strings have names q1,q2,q3,... There will be 100+ such strings.
This doesnt work at all. the setText(cs) line fails. Is there any way to convert string -> charsequence? Or to have it read as a resource file and not a string?
In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

I have tried to use the following code:

Evaluate the expression against the XML Document to get the result.
But I get "Cannot be resolved". Eclipse doesn't seem to be able to fix this import. I tried manually entering: javax.xml.xpath.XPath
But this did not work. Does anyone know any good source code that I can utilise, for Android platform? 1.5

Does anybody know of a work around for the android xml file string array inability to process string <item>'s that are not legal java variable names If not, is this not a major bug? Why does an item in an array need to generate a reference id anyway? Isn't this redundant?
View 2 Replies View RelatedGiven that scripting is not natively supported in Android and wrapping libraries like javax.script.ScriptEngine into your app will make it too large, is it possible to send a javascript string to an invisible WebView and have it evaluate the string and return you the results (another string)? I want to go this route because I want to save all my scripts to disk so my app can remain small. edit I need Java code to evaluate javascript strings not the other way around. addJavascriptInterface() doesn't help.
View 2 Replies View RelatedSo I ran into a problem today while working on my Android program. I have a class that turns that an XML string into a Java object (third party) and it works fine in as a regular java project but on Android I get this weird error:
CODE:.......
I hide my application name and my package for obvious reasons but I was wondering if anyone has ever encountered problems like this. Class is in the correct package, which is a library I have added. Other classes that I reference before are there and those can be made. Are there any other reasons a ClassNotFound Exception is thrown?
It would work something like this
someUtility.replace ("Hello, my name is {1}. What is your {2}?", "Mark", "name");

View 5 Replies View RelatedI have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.
