Im trying to add a vertical divider in chipgroup to separate primary chip from other chips. Just like YouTube:

I have attempted to add it through this method. In the Activity:

<HorizontalScrollView
    android:id="@+id/hscroll_categories"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:layout_marginBottom="10dp"
    android:scrollbars="none">
    <com.google.android.material.chip.ChipGroup
        android:id="@+id/chipgroup_categories"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="8dp"
        android:orientation="horizontal"
        app:singleSelection="true"
        app:selectionRequired="true"
        app:singleLine="true" />
</HorizontalScrollView>

item_chip_category.xml:

<com.google.android.material.chip.Chip xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center"
    app:chipStartPadding="18dp"
    app:chipEndPadding="18dp"
    app:chipMinHeight="40dp"
    android:textColor="@color/txt_category_chip_light"
    app:chipBackgroundColor="@color/bg_category_chip_light"
    app:chipStrokeWidth="1dp"
    app:chipStrokeColor="@color/stroke_category_chip_light"
    style="@style/Widget.MaterialComponents.Chip.Choice"
    android:textAppearance="?android:attr/textAppearance" />

vertical_div.xml:

<View xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="1dp"
    android:layout_height="match_parent"
    android:background="#424242"/>

And adding the chips and divider dynamically:

Chip …

我想在 PHP 中验证 URI （不仅仅是 URL），但找不到任何方法来做到这一点。

PHP 确实有parse_url()，但它不适用于 URI，找到一种正确的方法来验证 URI 结构会很有帮助，如下所示：
