android - 圆形进度指示器忽略宽度/高度属性并且不缩放

Question

我需要水平放置 4 个圆形进度条，如下所示:

所以我决定使用新的 Material 组件循环进度指示器(https://material.io/components/progress-indicators/android)。我传播链这4个进度条
在约束布局中，但它们不会缩放。看起来他们仍然有默认的 24dp 大小。例如，即使我尝试将宽度和高度硬编码为 200dp，输出仍然是小的进度条。

您必须使用 indicatorSize 属性:

   <com.google.android.material.progressindicator.CircularProgressIndicator
            android:indeterminate="true"
            android:layout_width="100dp"
            android:layout_height="100dp"
            app:indicatorSize="90dp"
            app:indicatorColor="@color/colorPrimary"
            ../>
