有没有办法使用显示入职进度的代码创建白点？

Answer 1

试试这个代码。在代码下方的可绘制对象副本中创建一个 xml。如果您想要不同的颜色，请将 ffffff 更改为 your_color

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="oval">
        <solid android:color="#ffffff" />
        <size
            android:width="8dp"
            android:height="8dp" />
    </shape>
</item>

</layer-list>

Answer 2

那些叫做 ViewPagerIndicator。

This library provide options for a lot of shapes and sizes in viewpager indicator with sample application.

Include one of the widgets in your view. This should usually be placed adjacent to the ViewPager it represents.
<com.viewpagerindicator.TitlePageIndicator
    android:id="@+id/titles"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent" />
In your onCreate method (or onCreateView for a fragment), bind the indicator to the ViewPager.
//Set the pager with an adapter
 ViewPager pager = (ViewPager)findViewById(R.id.pager);
 pager.setAdapter(new TestAdapter(getSupportFragmentManager()));

 //Bind the title indicator to the adapter
 TitlePageIndicator titleIndicator = (TitlePageIndicator)findViewById(R.id.titles);
 titleIndicator.setViewPager(pager);
(Optional) If you use an OnPageChangeListener with your view pager you should set it in the indicator rather than on the pager directly.
 //continued from above
 titleIndicator.setOnPageChangeListener(mPageChangeListener);
