我在真机上跑了跑，没发现不能滚动的问题。CommonNavigator只是一个HorizontalScrollView + LinearLayout，没有任何理由不滚动啊。对了，你那个RecyclerView的item动画不错！

一直会跳会第一个Fragment。只有点击到其他Fragment时才能正常滑动

我把自己的 CommonPagerTitleView自定义布局代码替换了Demo中ScrollableTabExampleActivity的initMagicIndicator2()中SimplePagerTitleView。发现刚进去也不能正常滑动。CommonPagerTitleView自定义布局中有个bug吧？

navigator.setSkimOver(true);
加上这句就好了=。=这行代码是什么含义

navigator.setSkimOver(true);
只有用于ClipPagerTitleView才有作用。
CommonPagerTitleView还是不行。

@hackware1993 可以正常滚动是因为我把CommonPagerTitleView 暂时先注释掉，换成ClipPagerTitleView了，ClipPagerTitleView是正常的，你试下去掉注释换成CommonPagerTitleView 。我的OPPO真机还是不行，就跟那gif里效果一样，要点击选择其他页面后才可以正常滑动。其他PagerTitleView我还没尝试，暂时只有CommonPagerTitleView 发现这问题。

因为我是想给Tab添加个5.0系统的点击波纹效果，所以才想到用自定义布局。现在折中的处理方法就是ClipPagerTitleView.setBackground(context.getResources().getDrawable(R.drawable.ripple_tab))，自己定义一个ripple.xml来设置背景。

hackware1993 commented on July 30, 2024

@452MJ 还是不行么

from magicindicator.

452MJ commented on July 30, 2024

@hackware1993 是的。CommonPagerTitleView 依旧不行。你把CommonPagerTitleView 注释去掉尝试下。

452MJ commented on July 30, 2024

大概知道原因了。如上面CommonPagerTitleView的监听中，onSelected&OnDeselected中setText，貌似会一直使焦点重置在第一个Tab，我把setText提到监听外，就不会有上述的情况。

之前也有使用过在监听中设置setText，不过Tab的数目比较少且固定3-4个，所以一直没有滑动的问题。

   ClipPagerTitleView titleView = new ClipPagerTitleView(context);
            titleView.setText(titleList.get(index));  这里调用了setText（）方法后相应的父类里onSelected 和onDeselected方法里如果也调用了setText方法就会出现这个问题 好像

一样的问题建议修复 @hackware1993 多谢~

from magicindicator.

CodeK1988 commented on July 30, 2024

原因 onDeselected onSelected 多次回调
解决方式自己维护 list集合加状态

var curItem: Int = -1 // -1 未选中 0 onDeselected 1 onSelected

建议修复~ 多谢 @hackware1993
