材料组件无法正常工作

我正在尝试使用AppCompact旁边的材料组件，所以我确实遵循了

1-我为AppCompact创建了样式父级，并为我的全局主题将其命名为AppTheme 

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:fontFamily">@font/iranyekanwebregular</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

2-根据这篇（https://material.io/develop/android/docs/getting-started/）文章，我在TextInputLayout中使用outLineBox样式制作了一个TextInputEditText，这正是上述文章所说的。

<com.google.android.material.textfield.TextInputLayout
            android:id="@+id/til_hive_desc"
            style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:inputType="text"
            android:textColorHint="@color/colorPrimaryDark">

            <com.google.android.material.textfield.TextInputEditText
                android:id="@+id/tied_movement_desc"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:hint="@string/add_apiary_desc"
                android:inputType="text"
                android:textColor="@color/colorPrimaryDark"
                android:textColorHint="@color/colorPrimaryDark"
                android:textSize="14sp" />

        </com.google.android.material.textfield.TextInputLayout>

，但是它不起作用，当我尝试打开活动时它崩溃了，这是错误消息：

，它要我提供Theme.MaterialComponents，当我实现它时，它破坏了我所有的自定义设计。 我该怎么办，请回答。

2 个答案:

答案 0 :(得分：1)

将样式父样式更改为材料样式，然后查看它是否起作用？

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

答案 1 :(得分：0)

您mentioned

  

通过将应用主题更改为继承来进行应用范围内的迁移   建议使用“材料组件”主题。但是，   一定要在以后进行彻底测试，作为现有布局中的组件   可能会改变他们的容貌和行为。

我尝试了相同的代码，但崩溃了

更改后

Theme.AppCompat.Light.DarkActionBar

收件人

Theme.MaterialComponents.Light.DarkActionBar

它正在运行，如果您想设置自定义样式，则可以在片段/活动中添加activity!!.setTheme(R.style.textTheme)并应用主题

希望它对您有用。
