Question

我的CirclePageIndicator没有显示圆圈，而是在我更改pageColor等时停滞不前。

我没有看到什么错误，并尝试了与我的问题相关的所有堆栈溢出答案。抱歉这个弱问题。

这是我的styles.xml

<style name="CustomCirclePageIndicator">
    <item name="fillColor">#FF000000</item>
    <item name="strokeColor">#FF000000</item>
    <item name="pageColor">#FF000000</item>
    <item name="strokeWidth">2dp</item>
    <item name="radius">10dp</item>
    <item name="centered">true</item>
</style>

Answer 1

你忘记了

myIndicator.setViewPager(myPager);

Answer 2

无法添加myIndicator.onPageScrolled(myViewPager.getCurrentItem(), 0, 0);也可能导致此问题。

例如：myViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { @Override public void onPageSelected(int position) { myIndicator.onPageScrolled(myViewPager.getCurrentItem(), 0, 0); } });

布局中的CirclePageIndicator没有改变？
