[SOLVED] Problems with the positioning of controls in a multi-field
form

Dear ALL,

I am developing an app using LAMW that has just one form with a
spinner control, an imageviewer, and several textviewer and edit
controls (see the attached image).

Needless to say, I have had problems getting the controls aligned. I
followed the instructions from here: https://github.com/jmpessoa/lazan
droidmodulewizard/blob/master/docs/GUIDesignWYSIWYG.md, but they cover
just a very simple case (one textviewer, one edit control and one
button) and therefore I did not find it much helpful.

I also followed the Contact Manager LAMW demo, which was much more
helpful, but even anchoring the controls as shown in the demo (ie,
with each control anchored to the previous one) I could not get
anything right. The interface of this demo is in fact fairly similar
to that of my app, except that I have a different disposition of the
controls in my form.

Could someone out there give a hand with getting the controls in this
form right? I attach my project files for your perusal.

Thanks in advance!

With best regards,

you have to try another method not laying your all control on 1 panel,
LAMW on android 10 had panel child control anchoring problem i think,
this problem disappear if you use android 9 or 12,13

thank you.

Hi, @Mongkey,

Quoteyou have to try another method not laying your all control on 1

think, this problem disappear if you use android 9 or 12,13
What "other method"? Please elaborate. I have the same problem (ie,
all controls overlapping) in both Android 10 and 5.5. On the other
side, the LAMW "Contact Manager" demo works well in both.

Regards,

Dear ALL,

With a little bit of patience and some trial-and-error, I got it
working fine! 

Therefore I will mark this question as SOLVED.

Thank you!

Dear ALL,

Although I have already marked this question as SOLVED, here am I
again to present the results of my efforts of the last few days in
developing a multi-field Android app using LAWM.

It is not a study in beauty, but it has the intended functionality and
demonstrates a few interesting features. I am not entirely satisfied
with the disposition of the components on the form, especially the
lack of spaces between the rows of components. Anyway, this is just an
experiment for the development of a similar, but more 'serious' and
sophisticated scientific app with more or less the same look-and-feel.

The full source code is attached. I will appreciate any cosmetic
and/or functional improvements.

With warmest regards,
