How to Round the Corners of a Button

How to make the corners of a button round?

If you want something like this

here is the code.

1.Create a xml file in your drawable folder like mybutton.xml and paste the following markup:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true" >
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#5e7974" />
            <gradient android:angle="-90" android:startColor="#345953" android:endColor="#689a92"  />            
        </shape>
    </item>
    <item android:state_focused="true">
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#5e7974" />
            <solid android:color="#58857e"/>       
        </shape>
    </item>  
    <item >
       <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#5e7974" />
            <gradient android:angle="-90" android:startColor="#8dbab3" android:endColor="#58857e" />            
       </shape>
    </item>
</selector>

2.Now use this drawable for the background of your view. If the view is button then something like this:

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:textColor="#ffffff"
    android:background="@drawable/mybutton"
    android:text="Buttons" />

Can`t round the corners of the button

Alright, I tested on my Studio with my launcher icon as the image inside and I got the required result. Here's the entire xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 android:layout_width="match_parent"
 android:layout_height="match_parent">

<ImageButton
    android:id="@+id/bottle"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:contentDescription="@null"
    app:srcCompat="@mipmap/ic_launcher"
    android:background="@drawable/rouncorners"/>

</android.support.constraint.ConstraintLayout>

And the xml to be placed in the drawable file is:

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="3dip" android:color="@color/profile_cover" />
    <corners android:radius="10dp" />
 </shape>

The result was as follows:

This is what you're looking for right? It have rounded corner and an image inside.

How to round the corners of a button

I tried the following solution with the UITextArea and I expect this will work with UIButton as well.

First of all import this in your .m file -

#import <QuartzCore/QuartzCore.h>

and then in your loadView method add following lines

    yourButton.layer.cornerRadius = 10; // this value vary as per your desire
    yourButton.clipsToBounds = YES;

Button with rounded corners and border with color

This one is what you need.

    public static void setRoundedDrawable(Context context, View view, int backgroundColor, int borderColor) {
    GradientDrawable shape = new GradientDrawable();
    shape.setShape(GradientDrawable.RECTANGLE);
    shape.setCornerRadius(20f);
    shape.setColor(backgroundColor);
    if (borderColor != 0){
        shape.setStroke(2f, borderColor);
    }
    view.setBackgroundDrawable(shape);
}

You can change corner radius and stroke width depends on what you need.
Hope it helps!

Rounded corners on material button

Update:

Answer by Gabriele Mariotti below is now better.

Old answer:

You need to inherit that style.

Add into your styles.xml:

 <style name="AppTheme.RoundedCornerMaterialButton" parent="Widget.AppCompat.Button.Colored">
        <item name="android:background">@drawable/rounded_shape</item>
 </style>

Add file drawable/rounded_shape.xml:

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"   >

    <solid
        android:color="@color/colorAccent" >
    </solid>

    <corners
        android:radius="11dp"   >
    </corners>

</shape>

And finally in your layout:

 <Button
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="Test Text"
       style="@style/AppTheme.RoundedCornerMaterialButton"/>

Edit: updated answer to use theme's color rather than hardcoded one.

Create a rounded button / button with border-radius in Flutter

1. Solution Summary

FlatButton and RaisedButton are deprecated.

So, you can use shape which placed in the style property, for TextButton and ElevatedButton.

There are some changes since Flutter 2.0:

• style: the property type has changed to ButtonStyle
• shape: the property type has changed to MaterialStateProperty<T>

2. Rounded Button

Inside the style property exists the shape property:

style: ButtonStyle(
  shape: MaterialStateProperty.all<RoundedRectangleBorder>(
    RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(18.0),
      side: BorderSide(color: Colors.red)
    )
  )
)

Square Button

For a square button you can use ElevatedButton or otherwise add:

style: ButtonStyle(
  shape: MaterialStateProperty.all<RoundedRectangleBorder>(
    RoundedRectangleBorder(
      borderRadius: BorderRadius.zero,
      side: BorderSide(color: Colors.red)
    )
  )
)

Complete Example

Row(
  mainAxisAlignment: MainAxisAlignment.end,
  children: [
    TextButton(
      child: Text(
        "Add to cart".toUpperCase(),
        style: TextStyle(fontSize: 14)
      ),
      style: ButtonStyle(
        padding: MaterialStateProperty.all<EdgeInsets>(EdgeInsets.all(15)),
        foregroundColor: MaterialStateProperty.all<Color>(Colors.red),
        shape: MaterialStateProperty.all<RoundedRectangleBorder>(
          RoundedRectangleBorder(
            borderRadius: BorderRadius.circular(18.0),
            side: BorderSide(color: Colors.red)
          )
        )
      ),
      onPressed: () => null
    ),
    SizedBox(width: 10),
    ElevatedButton(
      child: Text(
        "Buy now".toUpperCase(),
        style: TextStyle(fontSize: 14)
      ),
      style: ButtonStyle(
        foregroundColor: MaterialStateProperty.all<Color>(Colors.white),
        backgroundColor: MaterialStateProperty.all<Color>(Colors.red),
        shape: MaterialStateProperty.all<RoundedRectangleBorder>(
          RoundedRectangleBorder(
            borderRadius: BorderRadius.zero,
            side: BorderSide(color: Colors.red)
          )
        )
      ),
      onPressed: () => null
    )
  ]
)

Googles new buttons - how to do rounded ends in CSS

I think you're in the right track, just set it as larger as it makes you safe thinking about maximum height of button/item/div/whatever. I've checked Google Drive button by inspecting it, its border-radius is set to be 66px.

Notice that I've set the 4 corners in the same border-radius property, 2 of them being 0 just like the example. The border-radius are defined in the following order: top-left, top-right, bottom-right, bottom-left.

.button {  padding: 10px 30px;  background: red;  border: none;  border-radius: 0 100px 100px 0;}  

<button class="button">Hello world</button>

How to add rounded corners to a single side in HTML-CSS]

Try like following snippet, for more info take a look here:

.button {
  border: 1px solid #00bfff;
  border-bottom-right-radius: 30%;
  border-top-right-radius: 30%;
  padding: 20px;
  background: #00bfff;
}

<button type="button" class="button">Button</button>

Xamarin iOS Round only some corners of a Button

You can use MaskedCorners in your iOS class to control the display of graphics.

Here is my implementation class for your reference:

[assembly: ExportRenderer(typeof(CustomButton),typeof(CurvedCornersButtonRenderer))]
namespace xxx.iOS
{
    class CurvedCornersButtonRenderer : ButtonRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<Button> e)
        {
            base.OnElementChanged(e);
            Control.BackgroundColor = UIColor.Blue;
            Control.ClipsToBounds = true;
            Control.Layer.CornerRadius = 15;
            Control.Layer.MaskedCorners = CoreAnimation.CACornerMask.MaxXMinYCorner | CoreAnimation.CACornerMask.MaxXMaxYCorner;
        }
   
    }
}
