问题
I have read the documentation on the official website. But I was unable to implement Chip in my project following the documentation. Android Studio can't find and import Chip class as well as Chip view.
I have also noticed that on Google Developer site there is no reference for Chip class.
There are some similar questions. But all answers point to use a third-party library. But I am trying to use Chips component from android support library.
回答1:
The feature is included in support library version 28.0.0-alpha1. To use the feature:
In app gradle file:
android {
compileSdkVersion 'android-P'
}
dependencies {
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support:design:28.0.0-alpha1'
// OR
implementation 'com.android.support:design-chip:28.0.0-alpha1'
}
In Layout file:
<android.support.design.chip.Chip
style="@style/Widget.MaterialComponents.Chip.Entry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:chipIcon="@drawable/ic_arrow_drop_down_black_24dp"
app:chipText="hello"/>

If you are using the material library
You can use material chip com.google.android.material.chip.Chip
and implementation 'com.google.android.material:material:1.0.0'
add in build.gradle
Filter style="@style/Widget.MaterialComponents.Chip.Filter"
Choice Chips style="@style/Widget.MaterialComponents.Chip.Choice"
Entry input: style="@style/Widget.MaterialComponents.Chip.Entry"
