java.lang.UnsupportedOperationException：无法转换为color：type = 0x2

Question

只有在两台华硕智能手机（华硕Zenfone 5 - API 19和华硕Zenfone 2 - API 21）上充气EditText时才会抛出此异常。其他设备/模拟器工作正常。

布局

        <android.support.design.widget.TextInputLayout
            android:id="@+id/username"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingBottom="5dp"
            app:errorTextAppearance="@style/AppTheme.Error"
            app:hintEnabled="true"
            app:theme="@style/AppTheme.TextInput.White">

            <android.support.design.widget.TextInputEditText
                android:id="@+id/nickname"
                android:textColor="@color/white"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="@string/prompt_username"
                android:inputType="textPersonName"
                android:maxLines="1" />

        </android.support.design.widget.TextInputLayout>

主题

<style name="AppTheme.TextInput.White" parent="TextAppearance.AppCompat">
    <item name="colorControlNormal">@color/whiteC</item>
    <item name="colorControlActivated">@color/white</item>
    <item name="android:textColorHighlight">@color/whiteC</item>
    <item name="android:textColorLink">@color/whiteC</item>
    <item name="android:textColorHint">@color/whiteC</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<!--Error-->
<style name="AppTheme.Error" parent="AppTheme.Text.White">
    <item name="android:textSize">12sp</item>
    <item name="android:textStyle">italic</item>
</style>

我已经尝试过了：

• 用EditText替换TextInputEditText
• 从EditText
中删除textColor =“@ color / white”
• 降级以支持图书馆24,23。 （目前我在25.0.1）

Answer 1

感谢this comment问题通过将文字输入布局的主题更改为ThemeOverlay.AppCompat.Light来解决：

<style name="AppTheme.TextInput.White" parent="ThemeOverlay.AppCompat.Light">
    <item name="colorControlNormal">@color/whiteC</item>
    <item name="colorControlActivated">@color/white</item>
    <item name="android:textColorHighlight">@color/whiteC</item>
    <item name="android:textColorLink">@color/whiteC</item>
    <item name="android:textColorHint">@color/whiteC</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<!--Error-->
<style name="AppTheme.Error" parent="AppTheme.Text.White">
    <item name="android:textSize">12sp</item>
    <item name="android:textStyle">italic</item>
</style>

Answer 2

我遇到了同样的异常，但原因与 OP 问题完全不同，它只出现在 API 级别 21 以下。原因是在布局中使用了 ShapeableImageView；我在里面没有特殊的属性，但是一旦使用普通的ImageView，异常就消失了。

这是我使用的 ShapeableImageView：

<com.google.android.material.imageview.ShapeableImageView
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:padding="10dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toEndOf="@id/btn_change"
    app:layout_constraintTop_toTopOf="parent" />
