java.lang.UnsupportedOperationException：无法转换为颜色：对于 InputTextLayout，setErrorEnabled 上的 type=0x2

Question

我有一个 TextInputLayout：

<android.support.design.widget.TextInputLayout
    android:id="@+id/passwordLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColorHint="#FFF"
    android:theme="@style/TextInputLayoutWhite"
    app:errorTextAppearance="@style/ErrorText"
    app:hintTextAppearance="@style/TextInputLayoutWhite">

    <EditText
        android:id="@+id/passwordInput"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Password"
        android:imeOptions="actionGo"
        android:singleLine="true"
        android:textColor="#FFF"
        app:theme="@style/WhiteEditText">

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

我在我的活动中设置了一个错误，如下所示：

passwordLayout.setErrorEnabled(true);

这是在抛出java.lang.UnsupportedOperationException: Can't convert to color: type=0x2

如果我在我的 xml 布局中的 TextInputLayout 上设置 app:errorEnabled，则会显示错误文本，但是我不希望它始终“启用”，因为它为 textview 添加了额外的空间，这在我之前是不必要的需要显示错误。

任何想法为什么会抛出java.lang.UnsupportedOperationException？这是完整的堆栈跟踪：

更新

这是我的ErrorText 风格。请注意，即使我没有设置主题，也会引发上述错误：

<style name="ErrorText" parent="TextAppearance.AppCompat.Small">
    <item name="android:textColor">#FFF</item>
</style>

这是我的密码布局的声明：

TextInputLayout passwordLayout = (TextInputLayout) view.findViewById(R.id.passwordLayout);

Answer 1

this answer 表明问题出在您的android:theme="@style/TextLabelWhite" 上。删除它或将样式应用于您的父 AppTheme。
