I have a scrollview with a lot of components in the layout that there is inside it. The result is like that:
I want to know if is there a way to view all components in Android Studio because I need to make changes in the design and currently, by this way it is so difficult.
Thanks for your help.
Set the android:scrollY property on the ScrollView, say 50dp in the beginning and then keep on increasing as you move further down. Make sure you remove this property before production ;)
Did you try to add a new device definition,
Setting it with a bigger height,
And using that one in your preview ?
I've just give it a try and it works nicely !
You should set gone property with for view on top of layout, so you can see view below to edit it.
Let fun with android studio preview!

I created an empty activity for 'My Testing App' and it looks like the following in the preview section:
But when I generated a build apk and used the same in my cell phone the result was like the following:
I can only view the exit button on the very top left but the two other buttons, that should be above it are missing.
I tried to rearrange the icons on the screen as well. I made them to go to the bottom, to the right most, but I see no change when the apk is reinstalled.
How do I make them visible on the hardware?
Here is the snap of the code for this activity:
To quickly add constraints to your layout just click on the Infer Constraints button in the Layout Editor toolbar. Learn more about the feature here: https://developer.android.com/training/constraint-layout/index.html#use-autoconnect-and-infer-constraints
Right Click on you Layout and select "Convert View" Option.
then select "LinearLayout" Option.
it will show all three buttons in the output.
You have to learn about ConstrainLayout in Android
View in ConstrainLayout is not only drag and drop. You should link the constrain line in each view to reference with somewhere on the screen.
Any XML attributes prefixed with tools are removed when the app is compiled and are only rendered by Android Studio layout editor.
You need to properly set constraints in your ConstraintLayout, not use absolute positioning.
Or you may instead use RelativeLayout, LinearLayout, etc.
https://developer.android.com/training/constraint-layout/index.html
Start by reading this. Most of what you need is answered here. The problem is that your views are not properly constrained (basically they aren't linked to anything so when you run your app it doesn't know where to place them and just defaults to the upper left).
I am trying to use the new features of how to build a layout in ConstraintLayout in Android Studio 2.2.
When I try to use Adjust the view margins nothing happens. Margins are not added to any View, neither of these that I have already added or those which I would like to add.
The margins change only when I change the parameters InControl the margin for each view in the Properties window for every View individually. Have you already used this feature?
Thanks in advance for your help.
The margin value in the toolbar applies to newly created connections (with the exception of connections to the parent). It's also the value we use when you use some of the placement tools (spread, etc.).
I want to make a similar layout in Android with two additional button in bottom right and left corner. I'm new to android development GUI. Is grid layout the best option to achieve this or I should use any other layout.
I would not suggest using GridLayout. If you can, try to use Constraints layout, if that is not an option, use combination of RelativeLayout and LinearLayout where needed.
There is no 100% correct answer, try multiple ways and you will find one that suits you the best.
I am creating an Android app in Eclipse, but when I drag around a TextView, everything below it moves around as well.
This is when I haven't dragged anything.

This is when I drag the TextView just a bit.

The layout designer doesn't work very well in Eclipse. You could try Android Studio's layout designer (the new early access preview), that one is a bit better, but not by much.
The most common practice is to use the layout designer to only get started with and perhaps to use the Outline view panel to tweak some of the nesting of the layouts/views by dragging some of the nodes inside it, but then it's to dive directly into the xml code yourself. There is really no other substitute for doing that. The tool just isn't very good yet.
This is called a Relative Layout. In this case, the components are placed relative to the TextView, which is not so unexpected. It depends how you set relations in the layout XML. What layout you want to achieve?
You can either set that all the components are placed relative to the whole view, or use some specialized layout types like LinearLayout. It all depends on the effect you want to achieve.
I basically want to have several views aligned with each other using a relative layout. I can do so using xml, but unfortunately I can't find any documentation that tells me what methods I need to call to get the same effect in code (All the examples and things just use xml). Since the imageviews are being made dynamically xml isn't an option for what I want to do. I've looked at layoutparameters which seems to let me change some options, but I'm not seeing a method that will let me change alignment relative to another view. Any help is appreciated.
After playing around with it some more found that addRule is the method I need. Couldn't find it because I was looking for something with the term alignment in it.
Check out setLayoutParams in the Android documentation:
