Answer 1

更新您的应用主题以继承其中一个主题：

Theme.MaterialComponents
Theme.MaterialComponents.NoActionBar
Theme.MaterialComponents.Light
Theme.MaterialComponents.Light.NoActionBar
Theme.MaterialComponents.Light.DarkActionBar

例如：

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">

注意：使用“材料组件”主题可启用自定义视图inflater

最后得到了如何使用新材料芯片动态生成芯片的解决方案

谷歌没有提供chipsInput布局的任何文档或如何制作像布局一样的gmail地址。使用ChipDrawable不会给出芯片上的删除操作选项，因为无法调用setOnCloseIconClickListener。我能够使用Horizo​​ntalScrollView，ChipGroup和EditText

这是我的代码示例：

将以下新主题属性添加到现有应用主题：

<style name="Theme.MyApp" parent="Theme.AppCompat">

    <!-- Original AppCompat attributes. -->
    <item name="colorPrimary">@color/my_app_primary_color</item>
    <item name="colorPrimaryDark">@color/my_app_primary_dark_color</item>
    <item name="colorAccent">@color/my_app_accent_color</item>

    <!-- New MaterialComponents attributes. -->
    <item name="colorSecondary">?attr/colorPrimary</item>
    <item name="scrimBackground">@color/mtrl_scrim_color</item>
    <item name="textAppearanceHeadline1">@style/TextAppearance.MaterialComponents.Headline1</item>
    <item name="textAppearanceHeadline2">@style/TextAppearance.MaterialComponents.Headline2</item>
    <item name="textAppearanceHeadline3">@style/TextAppearance.MaterialComponents.Headline3</item>
    <item name="textAppearanceHeadline4">@style/TextAppearance.MaterialComponents.Headline4</item>
    <item name="textAppearanceHeadline5">@style/TextAppearance.MaterialComponents.Headline5</item>
    <item name="textAppearanceHeadline6">@style/TextAppearance.MaterialComponents.Headline6</item>
    <item name="textAppearanceSubtitle1">@style/TextAppearance.MaterialComponents.Subtitle1</item>
    <item name="textAppearanceSubtitle2">@style/TextAppearance.MaterialComponents.Subtitle2</item>
    <item name="textAppearanceBody1">@style/TextAppearance.MaterialComponents.Body1</item>
    <item name="textAppearanceBody2">@style/TextAppearance.MaterialComponents.Body2</item>
    <item name="textAppearanceCaption">@style/TextAppearance.MaterialComponents.Caption</item>
    <item name="textAppearanceButton">@style/TextAppearance.MaterialComponents.Button</item>
    <item name="textAppearanceOverline">@style/TextAppearance.MaterialComponents.Overline</item>

</style>

添加包含在android支持库中的chip组件。

实现'com.android.support:design:28.0.0-rc01'

<android.support.design.chip.Chip
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 

    />

将其添加到您的gradle文件中

XML

    <com.google.android.material.chip.Chip
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:chipText="MATERIAL CHIP" />
