我将MaterialCardView用作cardview
布局。现在,Android-studio开始向我显示,我应该更新为implementation "com.google.android.material:material:1.0.0"
而不是当前的1.1.0
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/edit_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical"
android:layout_margin="@dimen/activity_vertical_margin">
<com.google.android.material.card.MaterialCardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="8dp"
app:cardElevation="8dp">
<...more layout>
</com.google.android.material.card.MaterialCardView>
</LinearLayout>
与1.1.0,我得到崩溃
Error inflating class com.google.android.material.card.MaterialCardView
因此,我有3种情况:
1.0.0
并使用MaterialCardView
(有效,但不是首选方法)1.1.0
(或1.2.0-alpha)并使用androidx.CardView
(有效,但不是首选)1.1.0
并更改MaterialCardView
(首选,但不能使用)由于我想使用选项3,并且我没有任何解决方案,因此有人可以提供线索吗?
更新
我的风格(我也有style和style-night。在这里,我仅发布
style
):<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.DayNight">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="ThemeOverlay.AppCompat.navTheme">
<!-- Color of text and icon when SELECTED -->
<item name="colorPrimary">#ffffff</item>
<!-- Background color when SELECTED -->
<item name="colorControlHighlight">@color/colorPrimary</item>
</style>
</resources>
这是错误(来自 Logcat )

最佳答案
您也可以将其保留在materialcardview本身中:
<com.google.android.material.card.MaterialCardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="8dp"
**** android:theme="@style/Theme.MaterialComponents.Light" *****
app:cardElevation="8dp">
关于android - MaterialCard的:1. 1.0导致MaterialCardView崩溃,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/60182380/
