Answer 1

In your styles.xml

<style name="EditTextTheme">
  <item name="colorControlNormal">#ffffff</item>
</style>

apply theme for edittext

<EditText
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:theme="@style/EditTextTheme"/>

其他解决方案：在drawables中创建选择器xml文件

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffff" />
<stroke android:width="1dip" android:color="#ff9900" />
</shape>

在edittext中添加此行

android:background="@drawable/xml name"

Answer 2

转到 styles.xml 并将应用主题更改为：

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/white</item>  CHANGE THIS LINE
</style>

Answer 3

我遇到了更改全局主题的问题，我只想要一个EditText而不是全部，所以设置全局样式不是正确的答案。

相反，我只是这样做了：

<android.support.design.widget.TextInputEditText
    android:id="@+id/car_seller_notes_edit_text"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Hint"
    android:maxLength="1000"
    android:background="@drawable/edit_text_myunderline"/>

<强> edit_text_myunderline.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <!-- Draw a 2dp width border around shape -->
            <stroke android:color="@color/edit_text_underline_color" android:width="2dp" />
        </shape>
    </item>
    <!-- Overlap the left, top and right border using background color  -->
    <item android:bottom="2dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/window_background"/>
        </shape>
    </item>
</layer-list>

使用最新资料库

app / build.gradle

implementation 'com.google.android.material:material:1.2.0-alpha06'

styles.xml

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.Bridge">
    <!-- Customize your theme here. -->
    ...
</style>

布局XML

    <com.google.android.material.textfield.TextInputLayout
        style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox"
        android:id="@+id/text_input_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="16dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        >
        <EditText
            android:id="@+id/edit_text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="User Name"
            android:text="Chandler"
            android:textCursorDrawable="@null"
            />
    </com.google.android.material.textfield.TextInputLayout>

科特琳码

    text_input_layout.boxStrokeColor = Color.CYAN
    text_input_layout.defaultHintTextColor = ColorStateList.valueOf(Color.YELLOW)
    text_input_layout.setErrorTextColor(ColorStateList.valueOf(Color.RED))
    text_input_layout.setErrorIconTintList(ColorStateList.valueOf(Color.RED))
    edit_text.backgroundTintList = ColorStateList.valueOf(Color.LTGRAY)

当文本字段被聚焦/选中/突出显示时：

当文本字段处于错误状态时：

选择edittext时，主题/样式不会更改
