【问题描述】：

在某些设备中，当我尝试从 edittext 中选择文本进行复制时，会导致

算术异常

我在活动中使用该编辑文本扩展自 AppCompatActivity

这里是例外

此方法中的异常原因

android.widget.Editor.updateShowAsAction (Editor.java:6034)

这是我编辑文本的 xml 代码

            <EditText 
            android:id="@+id/etIdNumber"
            android:hint="@string/user_profile_myInfo_add_identification_dialog_et_hint"
            android:inputType="number"
            style="@style/et_rounded_corner_white_bg"
            />

这是我的风格

    <style name="et_rounded_corner_white_bg" parent="horizontal_margin">
     <item name="android:layout_width">match_parent</item>
     <item name="android:layout_height">wrap_content</item>
     <item name="android:textColor">@color/black</item>
     <item name="android:background">@drawable/editfield_bg</item>
     <item name="android:textColorHint">@color/font_very_light_gray</item>
     <item name="android:padding">@dimen/padding_5dp</item>
     <item name="android:layout_marginBottom">@dimen/padding_10dp</item>
     <item name="android:textCursorDrawable">@null</item>
</style>

【问题讨论】：

贴出相关代码

@johnrao07 没有具体的代码，我把它变成了一个普通的编辑文本

在哪些设备上导致问题？

@johnrao07 三星 Galaxy Note4 和三星 Grand

其他设备也能正常工作？这些设备是什么？

【参考方案1】：

当您双击 EditText 后设备在操作栏中设置复制/粘贴操作按钮时，会发生此错误。它将检索您的 actionButtonStyle 的 minWidth 属性。不要将此设置为 0dp，而是使用 1dp。代码示例：

<item name="android:actionButtonStyle">@style/myTheme.ActionButtonStyle</item>

<style name="myTheme.ActionButtonStyle" parent="@android:style/Widget.Holo.Light.ActionButton">
    <item name="android:background">@drawable/actionbutton_bg</item>
    <item name="android:textColor">@color/title_foreground</item>
    <item name="android:textSize">16sp</item>
    <item name="android:textStyle">normal</item>
    <item name="android:minWidth">1dp</item>
    <item name="android:paddingLeft">12dp</item>
    <item name="android:paddingStart">12dp</item>
    <item name="android:paddingRight">12dp</item>
    <item name="android:paddingEnd">12dp</item>
</style>

【参考方案2】：

它会做的工作！

<EditText 
 android:id="@+id/etIdNumber"
 android:hint="@string/user_profile_myInfo_add_identification_dialog_et_hint"
 android:inputType="number"
 style="@style/et_rounded_corner_white_bg"/>

从样式中移除这一行：

<item name="android:textCursorDrawable">@null</item>

【讨论】：

当我添加此行时它不起作用，键盘没有打开
