Chips

A Chip represents a complex entity in a small block, such as a contact. It is a rounded button that consists of a label, an optional chip icon, and an optional close icon. A chip can either be clicked or toggled if it is checkable.

Chips may be placed in a ChipGroup, which can be configured to lay out its chips in a single horizontal line or reflowed across multiple lines. If a chip group contains checkable chips, it can also control the multiple-exclusion scope for its set of chips so that checking one chip unchecks all other chips in the group.

You can also directly use a standalone ChipDrawable in contexts that require a Drawable. For example, an auto-complete enabled text field can replace snippets of text with a ChipDrawable using a span to represent it as a semantic entity.

Class definition
Class overview

Usage

The Chip widget provides a complete implementation of Material Design's chip component. Example code of how to include the widget in your layout:

<com.google.android.material.chip.Chip
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world"/>

Material Styles

Using Chip with an updated Material theme (Theme.MaterialComponents) will provide the correct updated Material styles to your chips by default. If you need to use an updated Material chip and your application theme does not inherit from an updated Material theme, you can apply one of the updated Material styles directly to your widget in XML.

Entry Chip

Use entry chips to represent a complex piece of information in a compact form.

This style usually contains an optional chip icon, optional close icon, and is optionally checkable.

<com.google.android.material.chip.Chip
    style="@style/Widget.MaterialComponents.Chip.Entry"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:chipIcon="@drawable/ic_avatar_circle_24"
    android:text="@string/hello_world"/>

Note: Entry chips are usually used with a standalone ChipDrawable.

Filter Chip

Use filter chips containing tags or descriptive words to filter a collection.

This style usually contains an optional chip icon, an optional close icon, and is always checkable.

<com.google.android.material.chip.Chip
    style="@style/Widget.MaterialComponents.Chip.Filter"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world"/>

Note: Filter chips are usually placed within a ChipGroup.

Choice Chip

Use choice chips to help users make a single selection from a finite set of options.

This style usually contains an optional chip icon and is always checkable.

<com.google.android.material.chip.Chip
    style="@style/Widget.MaterialComponents.Chip.Choice"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world"/>

Note: Choice chips are usually placed within a ChipGroup.

Action Chip (Default)

Use action chips to trigger an action that is contextual to primary content.

This style usually contains an optional chip icon and is never checkable.

<com.google.android.material.chip.Chip
    style="@style/Widget.MaterialComponents.Chip.Action"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:chipIcon="@drawable/ic_action_24"
    android:text="@string/hello_world"/>

Chip Touch Target

To ensure that a Chip is accessible, use a MaterialComponents.Chip style which uses an InsetDrawable to extend chip's touch target (when necessary) to meet Android's recommended accessibility touch target size. Developers can override chip's minimum touch target size using app:chipMinTouchTargetSize.

Handling Clicks

Call setOnClickListener(OnClickListener) to register a callback to be invoked when the chip is clicked.

Chip chip = (Chip) findViewById(R.id.chip);

chip.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View view) {
        // Handle the click.
    }
});

Or, call setOnCheckedChangeListener(OnCheckedChangeListener) to register a callback to be invoked when the chip is toggled.

Chip chip = (Chip) findViewById(R.id.chip);

chip.setOnCheckedChangeListener(new setOnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton view, boolean isChecked) {
        // Handle the toggle.
    }
});

Call setOnCloseIconClickListener(OnClickListener) to register a callback to be invoked when the chip's close icon is clicked.

Chip chip = (Chip) findViewById(R.id.chip);

chip.setOnCloseIconClickListener(new OnClickListener() {
    @Override
    public void onClick(View view) {
        // Handle the click on the close icon.
    }
});

RTL-friendly Chip Layout

Call setLayoutDirection(int) with View.LAYOUT_DIRECTION_LOCALE to ensure that the Chip's ancestor TextView renders the text with proper paddings. Without this, the initial rendering may look like the text has its padding set according to LTR direction.

Chip chip = (Chip) findViewById(R.id.chip);
chip.setLayoutDirection(View.LAYOUT_DIRECTION_LOCALE);

ChipGroup

A ChipGroup contains a set of Chips and manages their layout and multiple-exclusion scope, similarly to a RadioGroup.

Layout Mode

A ChipGroup will by default reflow its chips across multiple lines.

<com.google.android.material.chip.ChipGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

  <!-- Chips can be declared here, or added dynamically. -->

</com.google.android.material.chip.ChipGroup>

A ChipGroup can also constrain its chips to a single horizontal line using the app:singleLine attribute. If you do so, you'll usually want to wrap the ChipGroup in a HorizontalScrollView.

<HorizontalScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
  <com.google.android.material.chip.ChipGroup
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:singleLine="true">

    <!-- Chips can be declared here, or added dynamically. -->

  </com.google.android.material.chip.ChipGroup>
</HorizontalScrollView>

Chip Spacing

A ChipGroup can insert spacing between chips in a row or between rows of chips using the app:chipSpacing attribute. Different horizontal and vertical spacing can be set using the app:chipSpacingHorizontal and app:chipSpacingVertical attributes.

Multiple Exclusion Scope

A ChipGroup can be configured to only allow a single chip to be checked at a time using the app:singleSelection attribute.

<com.google.android.material.chip.ChipGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:singleSelection="true">

  <!-- ... -->

</com.google.android.material.chip.ChipGroup>

Handling Checked Chips

Call setOnCheckedChangeListener(OnCheckedChangeListener) to register a callback to be invoked when the checked chip changes in this group. This callback is only invoked in single selection mode.

ChipGroup chipGroup = (ChipGroup) findViewById(R.id.chip_group);

chipGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(ChipGroup group, @IdRes int checkedId) {
        // Handle the checked chip change.
    }
});

Or, call getCheckedChipId() at any time to get the checked chip. The return value is only valid in single selection mode.

Selection	`app:singleSelection`

Standalone ChipDrawable

A standalone ChipDrawable can be used in contexts that require a Drawable. The most obvious use case is in text fields that "chipify" contacts, commonly found in communications apps.

To use a ChipDrawable, first create a chip resource in res/xml. Note that you must use the <chip tag in your resource file.

res/xml/standalone_chip.xml

<chip
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:chipIcon="@drawable/ic_avatar_circle_24"
    android:text="@string/hello_world"/>

After inflating it dynamically, you can treat it as any other Drawable.

MainActivity.java

// Inflate from resources.
ChipDrawable chip = ChipDrawable.createFromResource(getContext(), R.xml.standalone_chip);

// Use it as a Drawable however you want.
chip.setBounds(0, 0, chip.getIntrinsicWidth(), chip.getIntrinsicHeight());
ImageSpan span = new ImageSpan(chip);

Editable text = editText.getText();
text.setSpan(span, 0, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Styles

Entry Chip is the default Material style for standalone ChipDrawables, but you can apply any of the other styles using a style attribute.

<chip
    xmlns:app="http://schemas.android.com/apk/res-auto"
    style="@style/Widget.MaterialComponents.Chip.Filter"
    app:chipIcon="@drawable/ic_avatar_circle_24"
    android:text="@string/hello_world"/>

Attributes

All the attributes on Chip can be applied to a ChipDrawable resource.
