I am designing my activity screen using eclipse but whenever I move an object e.g. a button it snaps around and I find it hard to position things where i want them.
Is there some setting I can change as as soon as I add a second button it snaps the other button to another position it is so annoying!
Also if I have an image button why can't i resize this, even with a normal button if i try to make it larger it just fits to the text and wont make the button bigger or it just flicks to a random place on the activity?
thanks
Probably you're trying to place components freely in the View but you're not considering the LayoutManager behavior. If you try to position your component in a LinearLayout, for example, the components will be placed following its rules, and these components will not stay where you drop them.
Try to understand better how the layouts works on Android. But for now, the AbsoluteLayout or RelativeLayout may be what you're looking for.
About the components size, you'll need to understand better how to use layout properties for these components. See the question How to size buttons for more information.

I have a case where have to dynamically change width of a button placed alongside another button in a horizontal linear layout. Button width change depend upon certain condition.
I have already tried many of solutions posted at stackoverflow, but the animation is never smooth. Lags on low-end devices. Some time the text within button seems to be sliding in which I don't want.
Here is what I want to achieve, pls see here how smoothly button width changes in google messages just want to achieve same animation.
Just for reference i've already top voted solutions here, for example Resizing layouts programmatically (as animation)
I have this problem that I have been trying to solve for about an hour now:
I want my app to resize in this fashion. When the window gets smaller, the views should move to stay inside the layout. So I don't need them to necessarily change size, but I do need them the move to stay within the window.
I have already tried GridPane but I want to be more precise than a grid (like AnchorPane) since I will have many views in the layout. However, if there is a workaround involving GridPane, I will be open to those solutions as well.
Thanks for any help and please leave a comment if you need further clarification.
The past few months I've been on a mission to implement widget support in my home screen replacement for Android, and it's proving rather difficult. I can now add and remove widgets to/from the home screen, but they can't be resized or moved yet. Currently what I'm trying to achieve is to resize them. To do this I have every widget embedded in a View, over which I put an overlay to make sure the touch events don't get caught by the widget underneath it (which caused trouble in past attempts).
What I have now is this layout for the container; http://www.hastebin.com/uwocaxukel.xml
The widget is put in the FrameLayout with id widgetContainer. As you can see in the screenshot below there is an orange dot in the middle of every border.
Now what I've always tried to do so far is catch touch events, figure out whether the user is trying to drag one of the borders (MotionEvent.ACTION_MOVE), and if he is, change the required properties in the LayoutParams object and call this.requestLayout () on the view. This is finicky, and less than ideal. Very often the touch events would stop registering because the user dragged faster than the view could refresh = user is no longer on the view which is listening for touch events, or the border would be too thin to hit.
So far it's all been very finicky. But there are other apps which seem to do this pretty much perfectly. Is there a library, a class I've overlooked, or something else I can use to achieve my goal?
This is an example of something that kind of worked, but was very finicky and just not remotely user-friendly; https://github.com/RobinJ1995/be.robinj.ubuntu/blob/869d48af2e7a3d8f0332f84edd2a8cd28564424a/UbuntuLauncher/app/src/main/java/be/robinj/ubuntu/widgets/WidgetHostView.java#L75
I have a custom popup window with a custom image background in which I need to place three custom buttons with their own background images. I have only one set of images for all the components, so I want all the parts to scale appropriately. My question now is how do I make sure that the buttons line up with the appropriate parts of the background image of the popup window. I have been experimenting with all sorts of widths and heights and I can not make it look consistent on all my test devices. Can anyone give me some pointers?
EDIT: Just to make it as clear as possible, the image below illustrates the kind of thing I am talking about:
I want the graphical button to line up with the arrows which are a part of the popup window background image.
arrange buttons in an xml layout and set this view to your custom popup and you can set images to buttons from code.
I am trying to create a layout that can fits my situation where I will need to have a layout that keeps the views like imageview or textview or probably a combination of a few. while on the top right of it, i will need to have two buttons on top.
However, this layout has to be dynamic where I can select whether if I want to show the buttons or not. How should I go about it?
You can use any layout you want really, although it sounds like a horizontal LinearLayout would fit your situation the best.
You can then control visibility of individual elements via setVisibility(View.GONE) and setVisibility(View.VISIBLE), or simply through addView.
