I would work with a piece of layout that isn't shown, the user must scroll to see what I have did. How can I do it? Can I join 2 different layout in one? I prefer to collocate item as I do with default layout. If it can help, I use Android studio. I prefer use elements without code, adding them from palette. An example :
You can use two different layout in main relative layout & whenever u want child layout just set visibility.
You will want to use a ScrollView for this. From the documentation:
Layout container for a view hierarchy that can be scrolled by the user, allowing it to be larger than the physical display.

I have two layouts, manageLayout and mainLayout. They have constraints to the parent on all sides. I need in a one time have manageLayout on the top of mainLayout, and on the other time mainLayout on the top of manageLayout. Of course, there is sense in using visibility=gone on one of them, but i need one layout on the background of another. Problem: layout on the background handle events from top layout. How to make lower layout(and his elements) untouchable when another layout is risen?
Layout tree image:

Code sample, where i want to disable communications with lower layout: https://pastebin.com/PeL7u3YD (not only isSaveEnabled=false had no effect, also isEnabled=false had no effects too)
If you just need an explanation.
Once you've initialized both your views for mainLayout and manageLayout, you will need to set an empty onClickListener on both of them. Basically, layouts should get the click but do nothing. This way you can block the layout and widgets underneath the view on Front from getting clicked.
Now for for switching view to front maintain a boolean to know which view is on the front and on your button click set the other view bringToFront() (Or try some other ways mentioned here if you want) and don't forget to switch the boolean value.
Let me know if this works for you or you have any issues regarding this.
According to my perception, you can make lower layout setEnable(false). I hope it will work.
Is it possible to hide individual views inside a group of a constraint layout.
I tried and failed & ultimately moved that view outside the group.
I did not find any document mentioning this behaviour.
Any one who can confirm?
whats you used for hide a view means INVSIBLE that take space of component and visiblity GONE not take any space of component .. so other component will effect.
can you show me your current code that i can understand properly.
thanks
I have a layout, but I need put more views (Buttons, EditText, etc), but how you know, the layout of the ADT is a bit small and I can't to set more views or know where is it, Somebody know How can I set more of these?
Thank you
Android isn't like iOS how you can just position elements with drag & drop.
RelativeLayout will position elements relative to each other and LinearLayout will lay out elements sequentially in a linear fashion, either vertically or horizontally. Both methods are better executed by actually writing the View XML yourself.
I suggest reading this: http://developer.android.com/guide/topics/ui/declaring-layout.html
If you want to actually see what you are adding to your layout without messing with the XML you could maybe change the device that the renderer is using to preview your layout.
I don't know what IDE you're using but in Eclipse and Android Studio you can change the device that your layout preview is rendered on. That way you can see what you're adding as you add it.
Then just make sure to put everything in a scroll view so users can access all the views and widgets you've put in that layout for your activity or fragment or dialog or whatever else it is.
I have some buttons, textboxes etc. in my android application, but when i drag them with my mouse in the xml file, their place doesn't change, or changes but they are not placed where i exactly wanted. How can i adjust their positions in the screen?
Thanks
Unfortunatly there is no such thing as absolute positionning in android ( RIP AbsoluteLayout deprecated since years.)
instead you have to position views according to their parents and according to other views in the same parent.
first you have to define wich parent you need ( if you want some viens in a single line go for a LinearLayout. a more custom layout: use a RelativeLayout ...)
then you can drag and drop views inside, but they will always snap a position relative to their parent and/or relative to the other views.
you can of course play with margins.
A list of layout type with some advanced techniques can be found on this page
Hope that helps.
You RelativeLayout as a group layout for your layout so positioning can somewhat easy using mouse.
Best is to arrange them from the xml code. Just Learn about using the Relative layout, LinearLayout and TableLayout
Learn how the XML works. For a LinearLayout, the items come in the order listed. For a RelativeLayout, the items are related by the values of their layout_XXX properties. Then you don't have to worry about the WYSIWYG tool not working.
FYI, the tool bundled with eclipse is extremely buggy. Don't count on whats on there being what's on your phone for anything non-trivial.
Like the others wrote it is easier to edit layout using xml editor. You can read more here http://developer.android.com/guide/topics/ui/declaring-layout.html.
I am using Eclipse and a ViewFlipper. In Graphical Layout, I want to see the second, third, and forth layouts of my views - right now, I can only see the first view. Any suggestions?
If I'm understanding you correctly, you want to see each view in the 'Graphical layout' tool? The way I do this, is instead of having all the layout work done in one xml (where your viewflipper is) I make each view a new layout xml. And then have each view (xml file) included into the view flipper by using this....
<include
layout="#layout/layout_media"
android:id="#+id/flipper_media" />
Hope this helps.
just put each layout in relative layout or linear what ever you are working with then with each layout you will work with the first one in the order and etc.. then at the end put each layout in the order you want later
I had to subclass the ViewSwitcher class to display an indeterminate ProgressBar until data is ready to display in the second view. I used isInEditMode() to determine whether I was actually running the app or just previewing in AS.
You should be able to add a custom attribute to choose which child to display. This might look a bit overkill, but if you happen to already have to subclass your ViewSwitcher or ViewFlipper, i think it is not a big deal.
I will try to put an example later.
