如何在Android中创建“多设置向导栏”？

Question

我想设置一个“向导栏”，它将显示如下设置过程的步骤。

因此，如果我处于向导的第二阶段，则将填充2个按钮，依此类推。但是，按钮填充和我可以手动完成的所有操作（这意味着它不必自动使用向导步骤），但是我不确定如何实施。

我目前在ViewPager 。 有任何想法吗？

mylayout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent">

</RelativeLayout>

 public void updateIndicators(int position) {
       DisplayMetrics metrics = getResources().getDisplayMetrics();
       int resizeValue = (int) TypedValue.applyDimension(
             TypedValue.COMPLEX_UNIT_DIP, 25, metrics);
       int defaultValue = (int) TypedValue.applyDimension(
             TypedValue.COMPLEX_UNIT_DIP, 15, metrics);

       }

    }

Make indicator view in xml like this.
