Reuse inflated views

Question

I am building a complex view based on dynamic data. Depending on the number of data elements in collections I am adding more views. Each of these subviews are complex and get inflated in the loop through the data collection.

This is of course inefficient and I would like to figure out a way to inflate the subview only once and then reusing them instead. Is this possible somehow?

PS: I do not want to build up the subviews in code (I know I could) because that would make things even messier due to the complexities and number of subviews, but if the performance would increase considerably I might take a look at that.

PPS: There is no visible performance problem but traceview that most of the time is spent inflating and if I can make it faster I would love to ;-)

Answer 1

you can check out the Google IO Session entitled 'The world of ListView'.

It explains very nicely how to prevent inflating the same view again and again, and how to reuse a particular view if it has been already inflated earlier.

Here is the link.

You can either download the .pdf file or view the video.

Hope it helps.
