TextInputLayout/TextInputEditText 在提示颜色替换后导致异常

问题描述

我在 TextInputLayout 中使用 TextInputEditText，从今天起它运行良好。我刚刚更改了颜色的属性，它导致了这个错误：

android.view.InflateException: Binary XML file line #97: Binary XML file line #8: Error inflating class com.google.android.material.textfield.TextInputLayout

我正在为我的应用样式使用自定义属性，因此我添加了新属性，并为该属性创建了相同的选择器，但颜色不同。

attrs.xml

<attr name="textInputFieldHint" format="reference"/>

styles.xml

<style name="AppThemeBlueColor" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge">
    ...
    <item name="textInputFieldHint">@color/textinputfield_hint_blue</item>
</style>

textinputfield_hint_blue.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/darkBlue" android:state_focused="true"/>
    <item android:color="@color/darkGrey"/>
</selector>

TextInputEditTextStyles：

<style name="TextInputLayoutStyle" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
    <item name="android:textColor">@color/form_edit_text_color</item>
    <item name="android:textColorHint">?attr/textInputFieldHint</item>
    <item name="hintTextColor">?attr/textInputFieldHint</item>
    <item name="BoxstrokeColor">?attr/textInputFieldOutline</item>
    <item name="errorTextColor">@color/colorRed</item>
    <item name="android:textSize">@dimen/text_normal</item>
    <item name="android:layout_marginBottom">@dimen/textInputLayout_margin_bottom</item>
</style>

<style name="TextInputEditTextStyle">
    <item name="android:layout_height">wrap_content</item>
    <item name="android:textColor">@color/form_edit_text_color</item>
    <item name="android:textColorHint">?attr/textInputFieldHint</item>
    <item name="BoxstrokeColor">?attr/textColorTertiary</item>
    <item name="errorTextColor">@color/colorRed</item>
    <item name="android:textSize">@dimen/text_normal</item>
    <item name="android:paddingStart">@dimen/textInputEditText_padding_start</item>
    <item name="android:singleLine">true</item>
    <item name="android:focusable">true</item>
    <item name="android:focusableInTouchMode">true</item>
    <item name="android:textCursorDrawable">@null</item>
</style>

我刚刚用 textInputFieldOutline 属性替换了 textInputFieldHint 属性。两者都是相同的选择器，但颜色不同。颜色确实存在，因为它用于其他布局组件。看起来像一些 Android 错误，因为当它的代码完全相同但颜色不同时，它没有任何理由无法工作。

解决方法

在你的styles.xml 文件中有一个错误：

<item name="textInputFieldHint">@color/textinputfield_hint_blue</item>

你应该从colors.xml文件而不是“textinputfield_hint_blue”写一个颜色名称，我猜这是一个xml文件本身在drawable文件夹中
