android-discuss, Disable a particular row in list view onCreate

 Hi,
I want to disable a particular row in list view based on some
condition on onCreate.
I can disable the row on itemClick.
But I want to disable that particular row onCreate.

Please provide me some piece of coode.I read in this forum that
override the adapter class but I am confused how to do that?

There's no reason to do this in onCreate - list view rows are created, if
necessary, when shown. That's when you'd disable it.



Um ... no.



Read the documentation and samples to see how to create custom adapters.

 Think about it from the user's perspective. They see a table row, and they 
expect to be able to interact with it. All you'll achieve is frustrating the 
users.

 Why do I want to disable?
 When list items will get created then I wants to disable a particular
item ,so that user cant interact with that particular row.Conditions I
am checking from the database.Once database will get updated then
again that particular row will become enabled based on some
conditions.But on create I am not able to disable that row.For each
row item I will check the conditions from database.

 lists work differently. The process of creating a list cell (and re-using 
it) is de-coupled from the process of updating it. The "disabling" needs to 
be done in the updating part. So when Android asks you to give it this 
particular cell so it can display it you could either try to return null 
(that might backfire) or set the cell's height to zero.

Of course you could disable touch events and key events for that cell but as 
I said before that is bad UI karma.

 Thanks.But my question is how to do that?

 Don't know - by reading the listview documentation maybe?
