Android Question Resizing for different screens

See here: https://www.b4x.com/android/forum/threads/supporting-multiple-screens-tips-and-best-practices.17647/

What I often do is just to place the views (if my app it tageting phones and there are just simple views) by %x and %y (so you know where they are - no matter how "big" the screen is - for me ot does not matter if it's 5, 6 or 7"). Then I adjust the textsizes Another one: Put all views on a scrollview (if you need more space for the views). Only on very small phones <5" this looks "crap". 99% Have devices >=5". So it's ok for me.

On tablets use another layout (there is "more visible space" so you can arrange the views much nicer). Search the forum for other methods starting from the link above.

I am exercising now with AutoScaleRate and AutoScaleAll. The results are not what I expected. I am testing on my device (960 * 540 and 256 dpi) and a Samsung tablet with a screen width of 21.7 cm ( 1280*800 and 145 dpi?); unfortunately I do not have more phones. I have been playing with the AutoScaleRate:

AutoScaleRate; Result on Tablet; Result on Phone

0.0: Tablet: 9,7 cm of width used; Phone: smaller usage than without AutoScaleAll
0.3: Tablet: 15 cm of width used; Phone: exactly as without AutoScaleAll
0.5: Tablet: 18 cm of width used; Phone: some views on right and bottom runs a little bit of screen
0.7: Tablet: complete screen used; Phone: some views on right and bottom run more of screen
1.0: Tablet: some views on right and bottom run of screen;Phone: some views on right and bottom run evenmore of screen

So 0.3 is best for Phone and 0.7 is best for Tablet.
The usage on tablet is not important; I just did it for testing. The real question is: when I stick to 0.3 will that be effective for other phones, with different size and dpi?

Browse the forum how to allign the views (anchors, etc.) but...

That is the reason why I use %x and %y and add all the views by code.

Example:


The views are exactly where I want. On phones this is absolutely ok (my opinion). Never had issues.

AutoScaleAll slightly increases or decreases the views sizes. Out of the three designer features: anchors, designer script and autoscale, auto scale is the least important.

Anchors are the most important and are very simple to use.
