Android Question DoEvents Replace

[bernardR]

Hello,

I call in Activity_Create subs for calculate size of views. Many use DoEvents.
It is important that all are executed before Activity_Resume.
When I replace DoEvents with 'Wait For ...", it works not more.
I joints an sample (See the log)

Is it possible to get same result with 'Wait For' as DoEvents ?
Thanks

or sleep(0) ?

It is important that all are executed before Activity_Resume.

Calling Sleep or Wait For will cause Activity_Create to be suspended and later resumed. It will only be resumed after Activity_Resume was called.

I call in Activity_Create subs for calculate size of views. Many use DoEvents.

Please post the relevant code.
1. I never seen a case where it is needed.
2. Why must it complete before Activity_Resume?

The relevant code is HERE.
There, it's a concrete problem.

I saw it later. Your solution based on StringUtils is the correct solution. It is better then relying on DoEvents.

Thanks. StringUtils seems a good solution for calculate without doevents the height of a string.
Is it sure that StringUtils don't use no doEvents inside ?

For calculate the width of a string, use a canvas is not sure (many errors in results).
The only sure method that I know is: Label.width=-2 and use reflector with doEvents (or wait For) for get the width.
Is there an other method without doEvents (or wait For), please ?

None of the official libraries call DoEvents inside.

For calculate the width of a string, use a canvas is not sure (many errors in results).

Check this example that uses Canvas.MeasureStringWidth: https://www.b4x.com/android/forum/threads/30642/#content
It is pretty accurate.
