Hello Everyone,
I am working on a Screen , the height of Screen reduced after click on CheckBox (when change listener call).
Here is the code :-

Note : the code is working fine in 5.0 OS but in 6.0 & 7.0 it creates problem.
Please let me know why I am getting the issue .

Answer 1

The problem is that you have made the app specific for a particular device on OS 5.0 which was obviously non-touch. Now on Touch devices, the sizes of buttons and checkboxes are much larger whereas you are trying to constrain them to smaller sizes. So the checkboxes will normally take whatever setextent you have done, but when focussed, they will try to make space for themselves which would disturb your screen layout. Remove the artificial constraining in the checkboxes and your immediate problem may get solved.
However, There are a LOT of issues in this code that may give rise to problems later.
Use of Screen.USE_ALL_HEIGHT will not make the take up the entire display.
You are unnecessarily overriding each and every field to somehow constrain their height. And you are doing it wrong. For example, in iaDescriptionEditField you have given full width for layout but then constrained its size. This will result in a the field not getting painted at the ends.
You have hardcoded widths and heights - including the fonts in pixels, this will make your app look very bad on high pixel density devices like the bold 3.
You are overriding a HorizontalFieldManager and then completely recreating the sublayout method. Better to simply extend the Manager class since you do not seem to using any facility of HorizontalFieldManager.
Remember that not all fields will give the correct getPreferredWidth/Height and you should only use these methods to make estimations during layout.
I would suggest that you rethink and rewrite your entire code after taking into account the different devices you would need to target. Use point based fonts and measurements instead of pixel based measurements.
All the best.
