Question

我的应用程序中有多个主题，并且我已经为我的按钮定义了一个形状，我喜欢通过更改应用中的主题来更改颜色。我已经完成了如下操作，但问题是固体标签的颜色，我不能在这里使用colorButtonNormal属性，

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
    <corners android:radius="7dp"/>
    <solid android:color="?attr/colorButtonNormal" />
</shape>

在我的布局中，我定义了按钮标记：

<Button
    android:id="@+id/sendCode"
    android:layout_marginTop="30dp"
    android:layout_width="200dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="@string/sendCode"
    android:textSize="@dimen/TextTwoSize"
    android:textStyle="bold"
    android:textColor="?android:textColorPrimary"
    android:background="@drawable/bot_shape"/>

这是我的style.xml文件的一部分，用于定义主题：

  <style name="myGreen" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimaryGreen</item>
    <item name="colorAccent">@color/colorAccentGreen</item>
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:colorBackground">@color/windowBackground</item>
    <item name="colorButtonNormal">@color/colorAccentGreen</item>

    <item name="colorPrimaryDark">@color/colorPrimaryDarkGreen</item>
    <item name="android:textColorPrimary">@color/textColorPrimary</item>
    <item name="android:textColorPrimaryInverse">@color/textColorPrimaryInverse</item>
    <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
    <item name="android:textColorSecondary">@android:color/white</item>
    <item name="android:windowBackground">@color/windowBackground</item>
    <item name="android:homeAsUpIndicator">@drawable/ic_keyboard_backspace_white_24dp</item>
    <item name="android:itemBackground">@android:color/white</item>
    <item name="android:textColor">@color/TextOneColor</item>
</style>
<style name="myRed" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimaryRed</item>
    <item name="colorAccent">@color/colorAccentRed</item>
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDarkRed</item>
    <item name="android:textColorPrimary">@color/textColorPrimary</item>
    <item name="android:textColorPrimaryInverse">@color/textColorPrimaryInverse</item>
    <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
    <item name="android:textColorSecondary">@android:color/white</item>
    <item name="android:windowBackground">@color/windowBackground</item>
    <item name="android:colorBackground">@color/windowBackground</item>
    <item name="android:itemBackground">@android:color/white</item>
    <item name="android:textColor">@color/TextOneColor</item>
    <item name="colorButtonNormal">?attr/colorPrimary</item>

</style>

我收到错误：

Answer 1

<强> ?attr/ will only work for api>=21 in drawables

对于以下版本，您不能在drawable中使用“？attr /”。

为每个主题尝试 adding separate drawable 并以编程方式进行设置。

您可以在布局xml文件中使用？attr /。所以你可以在按钮

中使用下面一行

android:background="?attr/colorButtonNormal"

如果你想要塑造，每个主题使用单独的drawable是更好的。

使用Android Shape Drawables的不同主题的不同按钮颜色
