请问：在RecycleView 中作为ITEM使用 并且自定义指示器后,指示器无改变！

[BuMiangYang]

item 布局如下： <cn.bingoogolapple.bgabanner.BGABanner android:id="@+id/banner" android:layout_width="match_parent" android:layout_height="130dp" android:scaleType="fitXY" app:banner_indicatorGravity="bottom|right" app:banner_pointDrawable="@drawable/selector_banner_white" app:banner_placeholderDrawable="@drawable/placeholder_banner" app:banner_pointAutoPlayInterval="3000" app:banner_tipTextColor="@color/color_title_bg" app:banner_tipTextSize="@dimen/textSize_titleSmall" app:banner_transitionEffect="alpha" /> selector_banner_white： <selector xmlns:android="http://schemas.android.com/apk/res/android">

<item>
    <shape android:shape="oval">
        <size android:width="6dp" android:height="6dp" />
        <solid android:color="#000" />
    </shape>
</item>

运行结果：除了指示 其他正常，app:banner_placeholderDrawable 属性添加只显示默认情况，不使用app:banner_placeholderDrawable 显示正常。

不清楚你这边的情况，我再 demo 里将 layout_header.xml 即作为 RecyclerView 的 header 又左右其 item，测试没问题。如果你那边还有问题的话，辛苦写个有问题的 demo 传到 GitHub

• layout_header.xml

  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">
  
  <cn.bingoogolapple.bgabanner.BGABanner
      android:id="@+id/banner"
      android:layout_width="match_parent"
      android:layout_height="100dp"
      android:scaleType="fitXY"
      app:banner_pointDrawable="@drawable/selector_banner_unequal"
      app:banner_indicatorGravity="bottom|right"
      app:banner_pageChangeDuration="1500"
      app:banner_placeholderDrawable="@drawable/holder"
      app:banner_tipTextSize="12sp"
      app:banner_transitionEffect="accordion"/>
  </LinearLayout>
