1- Chip

Chip are new component first introduced in Android SDK version 28. Which is basically an interface component consisting of icon and text, placed in a rectangular background with rounded corners.
In order to use the Chip object in the project you need to install it.
After it has been successfully installed, a library including Chip will be declared in the build.gradle (Module app) file.


implementation 'com.google.android.material:material:1.1.0'
 
Here is an XML code of a simple Chip:
Chip Sample

<!-- IMPORTANT: android:theme is required -->

<com.google.android.material.chip.Chip
    android:id="@+id/chip1"
    style="@style/Widget.MaterialComponents.Chip.Action"

    android:theme="@style/Theme.MaterialComponents.Light"

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Chip Action" />
theme attribute
The android:theme attribute is required for a Chip. Without this attribute, your entire application will not work, and it also will not notify you of that. I was surprised because of that when I first used a Chip.
  • android:theme="@style/Theme.MaterialComponents"
  • android:theme="@style/Theme.MaterialComponents.Light"
  • android:theme="@style/Theme.MaterialComponents.***"
style attribute:
The style attribute has 4 values which helps you to specify the type of Chips:
  • @style/Widget.MaterialComponents.Chip.Action (Default)
  • @style/Widget.MaterialComponents.Chip.Entry
  • @style/Widget.MaterialComponents.Chip.Choice
  • @style/Widget.MaterialComponents.Chip.Filter
Style Default
The style attribute is optional and its default value is known as "@style/Widget.MaterialComponents.Chip.Action".

Here are some characteristics of Chip Choice:
  • When Chip Choice is selected, its background color will look darker.
  • There is no check icon on the left, even if you set checkable=true.
  • Icon - Not displayed even if you set the value for it.

2- Chip Theme

The android:theme attribute is required for a Chip. Your application may not work if Chips do not have this attribute, or if you set an invalid value for them.
Some possible values are:
  • android:theme="@style/Theme.MaterialComponents.Light"
  • android:theme="@style/Theme.MaterialComponents.Bridge"
  • android:theme="@style/Theme.MaterialComponents.DayNight"
  • .....
android:theme="@style/Theme.MaterialComponents.Light"
android:theme="@style/Theme.MaterialComponents.Bridge"

3- Chip Listener

There are many events related to Chips, but basically there are 3 common events as follows:
  1. chip.setOnClickListener(View.OnClickListener)
  2. chip.setOnCloseIconClickListener(View.OnClickListener)
  3. chip.setOnCheckedChangeListener(CompoundButton.OnCheckedChangeListener)

4- ChipGroup

ChipGroup is used to contain multiple Chips. By default, Chips will be sorted on many of lines if one line cannot contain all the Chips.
However, you can set it to ensure that the Chips will be displayed on a single line.

<com.google.android.material.chip.ChipGroup
   app:singleLine="true"  
   ...>
   
</com.google.android.material.chip.ChipGroup>
ChipGroup can also work as a RadioGroup, which means that if one of the Chips is set to be checked, the rest of the Chips will be unchecked.

<com.google.android.material.chip.ChipGroup
   app:singleSelection="true"
   ...>
   
</com.google.android.material.chip.ChipGroup>
