Android material 芯片组件崩溃应用。无法充气xml

Question

尝试了来自两个支持库的芯片组件
com.google.android.support:design:28.0.0-rc01 和 material
com.google.android.material:material:1.0.0-rc01

StackTrace

android.view.InflateException: Binary XML file line #72: Binary XML file 
      line #72: Error inflating class com.google.android.material.chip.Chip 
      at android.view.LayoutInflater.inflate(LayoutInflater.java:551)
      at android.view.LayoutInflater.inflate(LayoutInflater.java:429)`

布局

<com.google.android.material.chip.Chip
    android:id="@+id/chip"
    style="style/Widget.MaterialComponents.Chip.Entry"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/account"
    app:closeIconEnabled="true" />`

Answer 1

终于找到了如何使用新的 material 筹码动态生成筹码的解决方案

Google 没有提供任何有关 chipsInput 布局或如何制作类似布局的 gmail 地址的文档。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 HorizontalScrollView、ChipGroup 和 EditText

这是我的代码示例：

将以下新主题属性添加到您现有的应用主题中：

<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 3

更新您的应用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">

Note: Using a Material Components theme enables a custom view inflater

Answer 4

您可以像这样在 xml 布局中添加 @style/Theme.MaterialComponents.Light 样式属性：

<com.google.android.material.chip.Chip
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="chip"
android:theme="@style/Theme.MaterialComponents.Light"/>

Answer 5

您可以使用Theme.MaterialComponents.**.Bridge替换您之前的主题。

例如，如果旧主题是 Theme.AppCompat.DayNight.NoActionBar，则新主题将是 Theme.MaterialComponents.DayNight.NoActionBar.Bridge。
