How to change the shape of Chips component in android?

Question

When I added ChipGroup and Chips to XML, first it gave me rendering issue which caused activity crash. I solved it by changing the support library version in the gradle.app from implementation 'com.google.android.material:material:1.2.0-alpha05' to alpha02 & changed AppTheme to "Theme.MaterialComponents.Light.DarkActionBar".

**Now the issue is that in the design section of androidStudio shape of the chip is default i.e. rounded but on emulator & actual device it is diamond shaped. I tried the app:chipCornerRadius="5dp" property but it did not gave the desired result.

How to change the shape of the chip to rounded/default?**

    </HorizontalScrollView>

Answer 1

Just add this line in both themes.xml.

<item name="chipCornerRadius">4dp</item>

Answer 2

In the Chip the default value of the corner is defined in the style by the shapeAppearanceOverlay attribute:

<item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.MaterialComponents.Chip</item>

with:

  <style name="ShapeAppearanceOverlay.MaterialComponents.Chip" parent="">
    <item name="cornerSize">50%</item>
  </style>

Just remove in your layout app:chipCornerRadius="5dp".
