在主题中定义colorControlHighlight,只要您使用默认的appcompat-v7按钮,高亮颜色就应该是开箱即用的.

选项2

这是一个示例,说明如何使用一些交叉渐变动画和阴影向后移植“材质”按钮样式,而不使用外部库.可以帮助你.

如果按钮将是深色背景上的白色文本(@ color / control_normal),并且高亮显示：

值/的themes.xml

在这里,我将覆盖整个主题的默认按钮样式：

<style name="AppTheme" parent="Base.AppTheme">
    <item name="buttonStyle">@style/Widget.AppTheme.Button</item>
</style>

值/ integers.xml

<!-- Some numbers pulled from material design. -->
<integer name="button_pressed_animation_duration">100</integer>
<integer name="button_pressed_animation_delay">100</integer>

值-V21 / styles.xml

Lollipop的按钮样式,它理解主题叠加并默认使用波纹.让我们用适当的颜料为它涂上颜色：

<style name="Widget.AppTheme.Button" parent="Widget.AppCompat.Button">
    <!-- On Lollipop you can define theme via style. -->
    <item name="android:theme">@style/ThemeOverlay.AppTheme.Button</item>
</style>

<style name="ThemeOverlay.AppTheme.Button" parent="ThemeOverlay.AppCompat.Dark">
    <!-- The magic is done here. -->
    <item name="colorButtonNormal">@color/control_normal</item>
</style>

价值观/ styles.xml

在棒棒糖之前它变得棘手.

<style name="Widget.AppTheme.Button" parent="Widget.AppCompat.Button">
    <item name="android:background">@drawable/button_normal_background</item>
</style>

绘制/ button_normal_background.xml

这是整个按钮的复合绘图.

<inset

    android:insetLeft="@dimen/abc_button_inset_horizontal_material"
    android:insetTop="@dimen/abc_button_inset_vertical_material"

                android:exitFadeDuration="@integer/button_pressed_animation_duration">

                <item
                    android:drawable="@drawable/button_shape_highlight"
                    android:state_focused="true"
                    android:state_enabled="true"/>
                <item
                    android:drawable="@drawable/button_shape_highlight"
                    android:state_pressed="true"
                    android:state_enabled="true"/>
                <item

        </item>
        <!-- Inner padding. -->
        <item android:drawable="@drawable/button_padding"/>
    </layer-list>
</inset>

绘制/ button_shadow.xml

这是未按下时的阴影.

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners
        android:bottomLeftRadius="3dp"
        android:bottomRightRadius="3dp"
        android:topLeftRadius="2dp"
        android:topRightRadius="2dp"/>
  <solid android:color="#2000"/>
</shape>

绘制/ button_shadow_pressable.xml

这是按下状态下的扩展阴影.当你近距离观察结果效果看起来很粗糙,但距离远远不够好.

<selector
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:ignore="UnusedAttribute"
    android:enterFadeDuration="@integer/button_pressed_animation_duration"
    android:exitFadeDuration="@integer/button_pressed_animation_duration">
    <item
        android:state_pressed="true"
        android:state_enabled="true">
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle">
            <corners
                android:bottomLeftRadius="5dp"
                android:bottomRightRadius="5dp"
                android:topLeftRadius="3dp"
                android:topRightRadius="3dp"/>
            <solid android:color="#20000000"/>
        </shape>
    </item>
    <item android:drawable="@android:color/transparent"/>
</selector>

绘制/ button_shape_normal.xml

这是主要的按钮形状.

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="@dimen/abc_control_corner_material"/>
    <solid android:color="@color/control_normal"/>
</shape>

绘制/ button_padding.xml

只需额外填充即可与“材质”按钮完全一致.

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@android:color/transparent"/>
    <padding
        android:left="@dimen/abc_button_padding_horizontal_material"
        android:top="@dimen/abc_button_padding_vertical_material"
        android:right="@dimen/abc_button_padding_horizontal_material"
        android:bottom="@dimen/abc_button_padding_vertical_material"/>
</shape>

绘制/ button_shape_highlight.xml

这是在正常按钮形状上绘制的高亮按钮形状.

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="@dimen/abc_control_corner_material"/>
    <solid android:color="@color/control_highlight"/>
</shape>

@ color / control_highlight可以指向

> @ color / ripple_material_dark – 半透明白色,用于深色背景> @ color / ripple_material_light – 半透明黑色,用于浅色背景>您定义的任何其他颜色.
