Setting Margin for widgets Programmatically. December 03, In this tutorial, I am going to explain how we can set margin for widgets programmatically. Actually, I spent a quite some time in this.
I tried with this class "android. But after trying for quite sometime, I realized the actual class, for that is "android. We can use any layout, not only LinearLayout. But, it should be from widget package.
The function is setMargins left, top, right, bottom ; the four arguments shows the margin for four sides respectively. Android LayoutParams Margin programmatically. Post a Comment.

Here is code that works without margins:. So that works fine, but how on earth do you give the buttons margins so there is space between them? I tried using LinearLayout. Is this impossible?
LayoutParams is a subclass of LinearLayout. MarginLayoutParamsas indicated in the documentation. In fact, by definition, everything has to be doable via Java though not necessarily via SDK-reachable methodssince XML is not executable code.
Due to variation in device screen pixel densities its good to always use DIP unit to set margin programmatically. Only thing here is to notice that LayoutParams should be imported for following package android. LayoutParamsor else there will be an error. February 20, Android Leave a comment.

Here is code that works without margins:. So that works fine, but how on earth do you give the buttons margins so there is space between them? I tried using LinearLayout. MarginLayoutParamsbut that has no weight member so it's no good. And it doesn't work if you pass it lp in its constructor either.
Is this impossible? Because it sure looks it, and it wouldn't be the first Android layout task you can only do in XML. MarginLayoutParams, but that has no weight member so it's no good. LayoutParams is a subclass of LinearLayout. MarginLayoutParamsas indicated in the documentation. In fact, by definition, everything has to be doable via Java though not necessarily via SDK-reachable methodssince XML is not executable code.
But, if you're aware of something, point it out, because that's a bug in the SDK that should get fixed someday. Note the "instanceof" check in case you try and run this against something that doesn't support margins.

Any way to set them in dps?Whenever possible, use Interface Builder to set your constraints. Interface Builder provides a wide range of tools to visualize, edit, manage, and debug your constraints.
By analyzing your constraints, it also reveals many common errors at design time, letting you find and fix problems before your app even runs. Interface Builder can manage an ever-growing number of tasks. You can build almost any type of constraint directly in Interface Builder see Working with Constraints in Interface Builder.
You can also specify size-class-specific constraints see Debugging Auto Layoutand with new tools like stack views, you can even dynamically add or remove views at runtime see Dynamic Stack View. However, some dynamic changes to your view hierarchy can still be managed only in code. You have three choices when it comes to programmatically creating constraints: You can use layout anchors, you can use the NSLayoutConstraint class, or you can use the Visual Format Language.
The NSLayoutAnchor class provides a fluent interface for creating constraints. To use this API, access the anchor properties on the items you want to constrain. Views, on the other hand, expose anchors for their edges, centers, size, and baselines. Layout anchors let you create constraints in an easy-to-read, compact format.
They expose a number of methods for creating different types of constraints, as shown in Listing As described in Anatomy of a Constrainta constraint is simply a linear equation. The layout anchors have several different methods for creating constraints.
Each method includes parameters only for the elements of the equation that affect the results. So in the following line of code:. The layout anchors also provides additional type safety. The NSLayoutAnchor class has a number of subclasses that add type information and subclass-specific methods for creating constraints. This helps prevent the accidental creation of invalid constraints.
For example, you can constrain horizontal anchors leadingAnchor or trailingAnchor only with other horizontal anchors. Similarly, you can provide multipliers only for size constraints. This method explicitly converts the constraint equation into code.
Each parameter corresponds to a part of the equation see The constraint equation. The end result is a considerable amount of boilerplate code, which is usually harder to read. For example, the code in Listing code is functionally identical to the code in Listing Unlike the layout anchor API, the convenience method does not highlight the important features of a particular constraint. As a result, it is easier to miss important details when scanning over the code.
Additionally, the compiler does not perform any static analysis of the constraint. You can freely create invalid constraints. These constraints then throw an exception at runtime. This provides a visually descriptive representation of the constraints. The Visual Formatting Language has the following advantages and disadvantages:.
Auto Layout prints constraints to the console using the visual format language; for this reason, the debugging messages look very similar to the code used to create the constraints.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I'll explain why I rather wouldn't want to use this approach:. I have a custom Button which extends Button. If the background is set to something else than the default background by calling either setBackgroundResource int id or setBackgroundDrawable Drawable dI want the margins to be 0. If I call this:. I want the margins to reset to -3dp I already read here how to convert from pixels to dp, so once I know how to set margins in px, I can manage the conversion myself.
But since this is called in the CustomButton class, the parent can vary from LinearLayout to TableLayout, and I'd rather not have him get his parent and check the instanceof that parent. That'll also be quite inperformant, I imagine. Also, when calling using LayoutParams parentLayout.
Question: Is there any easier way to set the margin of a single Button programmatically besides using LayoutParams? Because this. The mc instance you see is just a MarginContainer which contains offset -3dp margins and oml, omr, omt, omb and the original margins ml, mr, mt, mb. The basic idea is to get margin out and then update it.
The update will be applies automatically and you do not need to set it back. To get the layout parameters, simply call this method:. The LayoutParams comes from the layout of your view. If the view is from a linear layout, you need to import LinearLayout.
If you use relative layout, import LinearLayout. LayoutParamsetc. All two ways of updating margin above are updating in pixels. You need to do a translation of dp to pixels. As today, the best is probably to use Parisa library provided by AirBnB. However it is the parent's role to choose whether to allow margin or not. Consequently, not all ViewGroups respect margin. The most notorious example would be listview, where the margins of items are ignored.
Before you call setMargin to a LayoutParam, you should always make sure that the current view is living in a ViewGroup that supports margin e. LayoutParams does not even have setMargins method! The function below should do the trick.
However make sure you substitute RelativeLayout to the type of the parent view. In Android, how do I set margins in dp programmatically?
