Android Question How to avoid GUI Lags/Freezes?

[FrankBerra]

Hello Everyone

In my app i am loading some stuff (Panels, Labels, ImageViews) in a Scrollview.
While loading, the animations of other elements of the GUI get freezed.

I tryied to use Threading in this way

Dim Params(1) As Object
Params(0)="nothing"
ThreadHome.RunOnGuiThread("LoadAllTheStuff", Params)

Where LoadAllTheStuff is the subb that i usually call for loading everything in the ScrollView.

The code above seems to help me a bit. Is there another way to avoid freezes or lags?

You cannot add views from a background thread. Only the main thread can access UI elements.

How many views are you adding?

What is the difference between main and background thread?

I am adding about
- 18 panels
- 19 labels
- 12 different images (loaded with LoadImageSample)
- 1 image loaded one time and recycled 18 times when needed
- 1 edittext
(And in the future there will be more things to load)

This freezes the other animations and touch for about half second

Avoid using the Threading library. Your code will run on the main thread.

How long does it take to load the views without the bitmaps? Shouldn't take more than a few milliseconds.
