Change Chip Widget style programmatically not working - Android

Question

I\'m doing a list with Chips. I want this chips can be selected, so, taking a look to https://material.io/develop/android/components/chip/ I see I can have a \"Choice Chip\"

Answer 1

the CustomChipChoice is not a style it is just a reference to a style. therefore change R.style.CustomChipChoice to it : R.attr.CustomChipChoice

val newChip = Chip(context, null, R.attr.CustomChipChoice)

but before it you should add this CustomChipChoicein values.xml file in your project. for this. if your project does not have the values.xml create it in values directory.

then add CustomChipChoice like this.

values.xml

now in styles.xml add your style like this.

styles.xml

now that CustomChipChoice attr references to this style and now you can create your custom style in styles.xml file.

styles.xml

if you want to change text appearance of chip. here is ChipTextStyleAppearance. you can add it like this.

styles.xml

dont forget to add the AppTheme in androidManifest.xml on application or activity tags.

androidManifest.xml
