Android：TextInputLayout--为提示、底线和错误消息定制颜色

Question

我的布局如下所示：

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/email_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/email"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="E-mail"
            android:imeOptions="actionDone"
            android:inputType="textEmailAddress"
            android:maxLines="1" />

    </com.google.android.material.textfield.TextInputLayout>

</LinearLayout>

当我验证用户输入时，如果输入无效，我会添加一条错误消息，如下所示：

email_container.setError("You must fill this field!");

结果是：

...和其他解决方案试图解决android.support.design.widget.TextInputLayout包装简单的edittext时的情况。

email_container.setError("You must fill this field!");
email_container.setErrorTextColor(new ColorStateList(states, colors));
email_container.setDefaultHintTextColor(new ColorStateList(statesHint, colorsHint));

// Also tried with other states, but nothing
int[][] states = new int[][] {
        new int[] { android.R.attr.state_enabled},
        new int[] {-android.R.attr.state_enabled},
};

int[][] statesHint = new int[][] {
        new int[] { android.R.attr.state_enabled},
        new int[] {-android.R.attr.state_enabled},
};


int[] colors = new int[] {
        R.color.yellow,
        R.color.green,
};


int[] colorsHint = new int[] {
        R.color.black90,
        R.color.bt_text_blue,
};

有人知道怎么处理这个吗？

我们可以自定义样式来自定义TextInputLayout颜色。尝试此代码根据您的需要更改TextInputLayout颜色代码

style.xml

<style name="TextInputCustonColor" 
  parent="Widget.MaterialComponents.TextInputLayout.FilledBox">
    <!-- The color of the label  -->
    <item name="android:textColorHint">@color/colorPrimaryGolden</item>
    <!-- The color of the label -->
    <item name="android:colorError" tools:targetApi="o">@color/colorError</item>
    <!--the color of text-->
    <item name="android:textColor">@color/colorPrimaryGolden</item>
    <!--the color of background-->
    <item name="boxBackgroundColor">@android:color/transparent</item>

</style>

activity.xml

    <android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    card_view:errorEnabled="true"
    style="@style/TextInputCustonColor">

    <android.support.design.widget.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Password"
        style="@style/TextInputCustonColor"
        android:imeOptions="actionDone"
        android:inputType="textEmailAddress"
        android:maxLines="1" />

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