android - Android Studio 构建失败 - “在 [row, col]:[33:57] 处解析错误”
问题描述
我试图编译我的应用程序，但 ide 在“：app：mergeDebugResources”显示错误，即“ParseError at [row,col]:[33,47]”，我认为错误在我的 activity_main.xml 文件中，但我找不到它，请帮助。
这是文件：-
<com.google.android.material.card.MaterialCardView
android:id="@+id/rocketView1"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_marginLeft="4dp"
android:layout_marginTop="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="4dp"
app:cardCornerRadius="10dp"
app:cardElevation="2dp"
app:strokeColor="@color/cardview_shadow_start_color"
app:strokeWidth="1dp"
card_view:cardElevation="5dp">
错误发生在最后一行的最后一个字符处，在 '"5dp">(here)' 之后。
