根据错误日志：
com.king.view.splitedittext.SplitEditText.onSelectionChanged(Unknown Source:21)
推测可能是如下代码导致：
@OverRide
protected void onSelectionChanged(int selStart, int selEnd) {
super.onSelectionChanged(selStart, selEnd);
if (selStart == selEnd) {
setSelection(getText() == null ? 0 : getText().length());
}
}

输入的什么内容？emoji吗？

[zhangwenxiang26]

我这边的功能是，输入四位数字的验证码，譬如 1234；
这些错误信息是通过bugly收集的线上错误，我这边测试的时候没有复现这种错误！

那是否有配置 android:inputType="number" ？

[zhangwenxiang26]

配置了：
<com.king.view.splitedittext.SplitEditText
android:id="@+id/et_ver"
android:layout_width="match_parent"
android:layout_height="80dp"
android:background="@null"
android:inputType="number"
android:text=""
android:textSize="24sp"
android:textColor="@color/col_666"
app:setBorderColor="@color/tra"
app:setInputBorderColor = "@color/tra"
app:setBorderSpacing="2dp"
app:setBorderStyle="box"
app:setStrokeWidth = "1dp"
app:setMaxLength="4"
/>

[jenly1314]

配置了： <com.king.view.splitedittext.SplitEditText android:id="@+id/et_ver" android:layout_width="match_parent" android:layout_height="80dp" android:background="@null" android:inputType="number" android:text="" android:textSize="24sp" android:textColor="@color/col_666" app:setBorderColor="@color/tra" app:setInputBorderColor = "@color/tra" app:setBorderSpacing="2dp" app:setBorderStyle="box" app:setStrokeWidth = "1dp" app:setMaxLength="4" />

• 这样的话，目前可能不太好复现问题；
• 我抽空分析下 onSelectionChanged 和 setSelection 相关源码，等有结论了会答复你；
• 在问题没有解决之前，如果你有复现问题的步骤，也可以随时告知我一下，便于快速定位原因。

[zhangwenxiang26]

如果把 onSelectionChanged 这个函数的下面几行代码注掉，对整体功能会有什么影响吗？
if (selStart == selEnd) {
setSelection(getText() == null ? 0 : getText().length());
}

控制光标位置的，保证光标一直在最后
