Answer 1

更新您的应用程序主题以继承以下主题之一：

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”主题可以启用自定义视图充气器

最后获得了一种解决方案，该方法是如何使用新材料切屑动态生成切屑

Google尚未提供关于chipsInput布局或如何生成Gmail地址（如layout）的任何文档。使用ChipDrawable不会对芯片选项进行删除操作，因为无法调用setOnCloseIconClickListener。我能够使用Horizo​​ntalScrollView，ChipGroup和EditText进行操作

这是我的代码示例：

在您现有的应用程序主题中添加以下新主题属性：

<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>

Answer 5

添加chip组件，该组件包含在android支持库中。

  

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" 

    />
