How do I set the selected com.google.android.material.chip.Chip color? I don't want it to be the default gray. This is a single selection chip group.
Original documentation here
<com.google.android.material.chip.ChipGroup android:id="@+id/chipgroup" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginStart="16dp" android:layout_marginTop="16dp" android:layout_marginEnd="16dp" app:checkedChip="@+id/chip_program" app:chipSpacingHorizontal="32dp" app:chipSpacingVertical="8dp" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/detailText" app:singleSelection="true"> <com.google.android.material.chip.Chip android:id="@+id/chip_program" style="@style/Widget.MaterialComponents.Chip.Choice" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Program" app:chipEndPadding="16dp" app:chipStartPadding="16dp" /> <com.google.android.material.chip.Chip android:id="@+id/chip_normal" style="@style/Widget.MaterialComponents.Chip.Choice" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/program_normal" app:chipEndPadding="16dp" app:chipStartPadding="16dp" /> </com.google.android.material.chip.ChipGroup>

So you can use the setChipBackgroundColor(ColorStateList cl) method to set the color of your chip and then you can add an setOnClickListener(new ...) to toggle with selection and non-selection like the following code: yourchip. setOnClickListener(new View.
Chip chip = new Chip(context); chip. setBackgroundcolor(getResources(). getColor(R. color.
Chips are compact elements that represent an attribute, text, entity, or action. They allow users to enter information, select a choice, filter content, or trigger an action. The Chip widget is a thin view wrapper around the ChipDrawable , which contains all of the layout and draw logic.
Just set an attribute app:chipBackgroundColor and pass a color state list to it:
<android.support.design.chip.Chip android:id="@+id/test" android:layout_width="wrap_content" android:layout_height="wrap_content" android:checkable="true" android:clickable="true" android:focusable="true" app:chipBackgroundColor="@color/bg_chip_state_list" app:chipText="Test" /> bg_chip_state_list looks like this:
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:color="@color/colorSecondaryLight" android:state_checked="true" /> <item android:color="@color/colorPrimaryDark" /> </selector> However I also had to set android:clickable to true to make this work

Using a ColorStateList is a proper way. The only thing I want to add is using custom defined style much more clear to read especially if you want to customise a bunch of properties.
Among other things, one common style applied to all views allows you to make changes in one place that apply immediately to all views
styles.xml
<style name="CustomChipChoice" parent="@style/Widget.MaterialComponents.Chip.Choice"> <item name="chipBackgroundColor">@color/background_color_chip_state_list</item> <item name="android:textColor">@color/text_color_chip_state_list</item> </style> text_color_chip_state_list.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_checked="true" android:color="@color/color_checked" /> <item android:state_checked="false" android:color="@color/color_unchecked" /> </selector> background_color_chip_state_list.xml
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:color="@color/color1" android:state_checked="true" /> <item android:color="@color/color2" /> </selector> After that all you need is apply your custom style for all the Chip views like this.
<android.support.design.chip.Chip android:layout_width="wrap_content" android:layout_height="match_parent" style="@style/CustomChipChoice" android:checkable="true" android:clickable="true" android:focusable="true" android:text="Chip text" /> If you love us?
