Listview...how to conditionally replace a value with a string

Question

Hi, my ANDROID app presents a listview, from a database cursor and XML, that needs to replace the values in a column with various words based on the integer value contained in the cursor. For example, if the value is -1, replace it with the word "Invalid", but if the value is >= 0 then just display the value.

I was under the impression this could magically be done via XML... TIA.

Answer 1

you can either use JS regular expressions (regexp) to replace them or use PHP Class

Answer 2

Since you don't state what language you are using, there might be some difference to the language of your choice:

yourValue = ( '-1' == yourValue ) ? 'Invalid' : yourValue;

This will replace the contents of yourValue with 'Invalid' if it is -1 or let it stay the same.

You need to modify this depending on how you access your variables (i.e. dollar signed prefixed: $yourValue).

If your language is type-aware, you might want to make sure that yourValue is already a string.

This is what you should do when printing the output or while reading the content of your file. XML itself does not change the values for you.
