[android-developers] Re: Move buttons within Layout
I'm still stuck on this problem. I tried to solve it by making the
whole activity dynamic. But still the button is positioned at top
left.
I can't see why
ok.layout(k.getLeft(), k.getTop(), k.getRight(),k.getBottom());
isn't repositioning the button, even if it shows the right Values on
LogCat.
I really need some help on that !

Ok. Here's some more information about my App.
I'm going to create a keyboard app. Or rather an App where you can
define your own keyboard. Therefore I have two Activities A and B.
Activity A:
Here I want to create a single key. This is currently realized by
configuring a button.
The buttons size can be customized with a progress bar. One for height
and one for width. Also some letters/text can be added.
Then, height, width and the text of the button is send via an Intent
to Activity B.
Activity B:
On Activity B the current Button gets its properties out of the Intent
and via Gesture you can set it somewhere on the screen.
Afterwards the button get saved in an Arraylist.
Everytime I call Activity B the Arraylist is read and the buttons
should be shown on their position as before defined.
So the screen should be filled with buttons until the keyboard is
ready.
Then I want to create the keyboard (but I have no idea how yet ;) )
But as mentioned before, after reading the Arraylist the buttons loose
their position.

Thank you for your replies. But I still don't get it... Could you please explain how I should use the LayoutParams ? I thouht I only can use them with FILL_PARENT, WRAP_CONTENT and addRule() but not to define a position with specific values. @pskink How would you do that ?

I thouht I only can use them with FILL_PARENT, WRAP_CONTENT and addRule() but not to define a position with specific values. That's because you can't define a position with specific values. Step #1: Design the layout in XML the way the widgets are originally. You probably already have this already. Step #2: Create an equivalent layout in XML the way the widgets will be after your move. Step #3: Figure out the right changes to LayoutParams, margins, and whatnot to change your widgets, in Java, from the state the widgets start in (Step #1) to the state you want the widgets in after the move (Step #2). You cannot just arbitrarily position widgets wherever you want -- their position is dictated by their layouts. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training in US: 26-30 April 2010: http://onlc.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

That's because you can't define a position with specific values. Um, why not ? It worked well in onGesturePerformed-Method. That's why I'm thinking it also should be working. And I can't create a layout in XML, cause I don't know how many and where the widgets would be moved. err, well, LinearLayout.java ? :-) ok, will have a look at it. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Move buttons within Layout
You cannot pass a Button via an Intent. You're right. I only pass the height, width and text of the button I customized in Activity A. Activity B cannot modify the UI of Activity A. Activity B cannot safely reuse the widgets of Activity A. I don't want to modify the UI of Activity A. Activity B has its own UI or rather Activity B's Ui is made of those buttons. Therefore I want to move and show the buttons on Activity B. Maybe I schould post some more code for clarification ?
