在小米手机无限 requestLayout(), 导致文字抖动、不断恢复初始位置等问题 [BUG]

[sunny-zhang-98]

重新布局导致重新选择Page
重选Page导致Tab的onSelect执行
在OnSelect的时候设置了字体 Bold 导致了再次重新布局

暂时的解决方案：
mReselectWhenLayout = false

我不知道作者在这个字段注释中说的极端情况是什么情况

MagicIndicator/magicindicator/src/main/java/net/lucode/hackware/magicindicator/buildins/commonnavigator/CommonNavigator.java

Line 52 in e14fa79

private boolean mReselectWhenLayout = true; // PositionData准备好时，是否重新选中当前页，为true可保证在极端情况下指示器状态正确

[joymingchen]

极端情况可能是指视图出现错乱的情况，我遇见过这种情况，估计作者是为了确保视图正确
但我很好奇为啥只是小米手机会有这种情况，反复onlayout的情况

[hpdx]

我今天也遇到这个问题了，使用@Doinng提供的方案 commonNavigator.isReselectWhenLayout = false 暂时解决了问题 @joymingchen

[WayneLyn]

@hackware1993 想问下这个mReselectWhenLayout = false这个办法是解决小米手机的方案么？还有其他方法优化么。。小米手机上不停抖动恢复位置也太奇怪了

[hackware1993]

你先试试 mReselectWhenLayout

[WayneLyn]

这样是可以的。但是我看您之前的注释说这个true是为了保证极端情况下选中正确的tab。想问下这个极端情况有多极端...大概都有啥场景会出现，想了解一下。我担心改为false的话会有新的问题

[hackware1993]

这个极端情况可能是早期 Android 版本的 bug。

[SelectSex]

这样应该能保证极端情况，且不会循环layout了，isReselectWhenLayout还是有点用的，但是无限调用太恐怖了，所以，我们在初始化adapter和调用notifyDataSetChanged的时候 将isReselectWhenLayout变成true，且layout只调用一次就改为false防止无限调用，
至于打印 requestLayout() improperly called by *****Fragment$initTabLayout$1$1$1$getTitleView$1{64008db VFED..C.. ......ID 241,0-440,115} during layout: running second layout pass
我们可以

[lhhailong]

不用那么麻烦 在这儿加个判断就好了

[lhhailong]

[Er3c]

今天也遇到这个问题了，应该是修改TextView的字体导致一直requestLayout，只要在onLayout中判断下是否是重复layout就行

[ToFigting]

我按照楼上的写法改了之后确实不会requestLayout，但是也引入了别的问题。初始化不会选择第一个tab下划线不显示出来，tab展示不全的问题。无奈又改了会去

[qweenhool]

如果初始化的时候就要跳到某一个item，那就在setCurrentItem之后调一下就行
new Handler().postDelayed(new Runnable() { @Override public void run() { if (commonNavigator != null) { commonNavigator.setReselectWhenLayout(false); } } }, 1000);

[xiaozhao0331]

大佬们最后的终极方案是什么 为什么按楼上的方案 没有选中效果了

[superoidlau-lgtm]

有人能总结下最后的解决方案吗？这个issue中涉及的两个问题：

1. 在小米手机上requestLayout频繁输出
2. 默认不选中第一个item，如何处理？
