如何使用Android支持库中的Chips组件? [英] How to use Chips component from android support library?

问题描述

我已阅读官方网站上的文档.但是，根据文档，我无法在我的项目中实现Chip. Android Studio无法找到和导入 Chip 类以及 Chip 视图.

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.

我还注意到，在 Google Developer网站上，没有关于Chip类的参考

I have also noticed that on Google Developer site there is no reference for Chip class.

还有一些类似的问题.但是所有答案都指向使用第三方库.但是我正在尝试使用android支持库中的Chips组件.

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.

推荐答案

该功能包含在支持库版本28.0.0-alpha1中. 要使用该功能:

The feature is included in support library version 28.0.0-alpha1. To use the feature:

在应用gradle文件中:

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'
}

在布局文件中:

<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"/>
