MaterialButton with specific corners rounded #136

Comments

TanyaYu commented Jun 7, 2018

I am trying to make a button with only one side rounded (left or right).

Since the attribute app:cornerRadius is applied to all four corners of the button, I’ve tried to set the background:

But it didn’t work, because I suppose setting a custom background is not supported for it.

Any ideas how to reach only one rounded side for MaterialButton?

Hi @TanyaYu,
You can achieve this working with MaterialShapeDrawable. You’ll be able to set custom corners treatments to the MaterialShapeDrawable, and apply it to your button.

Try this and modify it.

How do i do this while retaining the onClick feedback animations?
e.g. ripple for api >= 21
e.g. color change api

AndroidDeveloperLB commented Oct 31, 2019 •

@tommybuonomo Pretty sure it’s supposed to be in pixels.
Also, when I choose it this way, it becomes black and without any effect when clicking.
How can I set it to just have this shape for the button, yet keep the color and the clicking effect ?
I’ve also noticed that it’s deprecated and that we should use ShapeAppearanceModel instead:

So I think the correct way to do something like that could be like:

Rounded corners on material button

I’m following the tips from questions like this to create a button style like suggested on Material Design.

However, I need to change the corner radius and haven’t been able to do so by inheriting Widget.AppCompat.Button.Colored style and setting the radius parameter.

How can I have the same style but with rounded corners?

Add the dependency to your build.gradle :

In this case you can use a MaterialButton in your layout file:

Use app:cornerRadius attribute to change the size of corner radius. This will round off the corners with specified dimensions.

You can also customize the corners using the shapeAppearanceOverlay attribute.

The official doc is here and all the android specs here.

With Jetpack Compose 1.0.x use the shape parameter:

OLD Support Library:

With the new Support Library 28.0.0, the Design Library now contains the Material Button .

You can add this button to our layout file with:

You can set the corner radius with this attribute:

• app:cornerRadius : Used to define the radius used for the corners of the button

Create an xml file named roundedbutton.xml in drawable folder

Finally set that as background to your Button as android:background = «@drawable/roundedbutton»

If you want to make it completely rounded, alter the radius and settle for something that is ok for you.

If using Android Studio you can just use:

this works fine for me, hope this helps someone.

Create a drawable/button_states.xml file containing:

Use it in button tag in any layout file

(This library is deprecated and no new development is taking place. Consider using a FAB instead.)

If you want a FAB looking circular button and you are using the official Material Component library you can easily do it like this:

If you change the size of the button, just be careful to use half of the button size as app:cornerRadius .

Set that on your XML drawable resources, and simple use and image button with an round image, using your drawable as background.

and add this to the button code

Used the shape as oval. This makes the button oval

You can make a ImageButton with circular background image.

use ImageButton instead of Button.

and make Round image with transparent background

You can use a MaterialButton :

and apply a circular ShapeAppearanceOverlay with:

For a round button create a shape:

use it as a background of your button link

Yes it’s possible, look for 9-patch on google. Good articles :

I simply use a FloatingActionButton with elevation = 0dp to remove the shadow:

Just use the MaterialButton

• width equal height
• cornerRadius is half of the width or height

look into built in android drawables:

You can use google’s FloatingActionButton

1. Use the Image Buttons and make the background as the image you want.
2. Create the images from the android asset studio link —

and download it, extraxt it , inside that look for mipmap-hdpi folder.

copy the image from the mipmap-hdpi folder and paste it in the drwable folder of your android project.

Now set the background as that image.

I went through all the answers. But none of them is beginner friendly. So here I have given a very detailed answers fully explained with pictures.

Open Android Studio. Go to Project Window and scroll to drawable folder under res folder

Right click, select New —> drawable resource folder

In the window that appears, name the file rounded_corners and click on OK

A new file rounded_corners.xml gets created

Open the file. You are presented with the following code —>

Replace it with the following code —>

Here the design view can be seen on the right side

Adjust the value in android:radius to make the button more or less rounded.

Then go to activity_main.xml

Put the following code —>

Here I have placed the Button inside a RelativeLayout . You can use any Layout you want.

For reference purpose MainActivity.java code is as follows —>

I have a Pixel 4 API 30 avd installed. After running the code in the avd the display is as follows —>

You can use one of Material button styles. For example:

Also starting from the version 1.1.0 you can also change the shape of your button. Just use the shapeAppearanceOverlay attribute in the button style:

The shapeAppearance allows also to have different shape and dimension for each corner:

With Jetpack Compose 1.0.x you can use the shape parameter:
