Question

我有一个RelativeLayout，背景是一个有参考颜色的drawable。我想根据样式改变drawable中的颜色。

我尝试了2个选项，但其中任何一个都在运行：

选项1：

RelativeLayout

<RelativeLayout
    style="@style/pink"
    android:background="@drawable/circlebutton"
    android:layout_width="wrap_content"
    android:layout_alignParentLeft="true"
    android:id="@+id/circlebutton_image_map"
    android:layout_height="wrap_content">
            <ImageView
                android:layout_marginTop="20sp"
                android:layout_centerHorizontal="true"
                android:layout_alignParentTop="true"
                android:layout_width="@dimen/icon_size"
                android:layout_height="@dimen/icon_size"
                android:src="@drawable/map_verdelab"/>
</RelativeLayout>

样式（res / values / styles.xml）

<style name="pink">
    <item name="normalcolor">@color/rosa_normal</item>
    <item name="lightcolor">@color/rosa_light</item>
    <item name="shadowcolor">@color/rosa_letter_shadow</item>
</style>

可绘制（res / drawable / circlebutton.xml）

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
    <layer-list >

        <item>
            <shape android:shape="oval">
                <size android:width="200sp" android:height="200sp" />

            </shape>
        </item>
        <item android:top="12sp" android:left="12sp" android:right="6sp" android:bottom="6sp">
            <shape android:shape="oval">
                <solid android:color="?shadowcolor"/>
            </shape>
        </item>
        <item android:top="12sp" android:left="12sp" android:right="8sp" android:bottom="8sp">
            <shape android:shape="oval">
                <gradient android:angle="315" android:startColor="?lightcolor" android:centerColor="?normalcolor" android:endColor="?normalcolor" />
            </shape>
        </item>
    </layer-list>
    </item>
<item  >

    <layer-list >
        <item>
            <shape android:shape="oval">
                <size android:width="200sp" android:height="200sp" />

            </shape>
        </item>
        <item android:top="10sp" android:left="10sp" android:right="6sp" android:bottom="6sp">
            <shape android:shape="oval">
                <solid android:color="?shadowcolor"/>
            </shape>
        </item>
        <!-- Inset -->
        <item android:top="10sp" android:left="10sp" android:right="10sp" android:bottom="10sp">
            <shape android:shape="oval">
                <gradient android:angle="315" android:startColor="?lightcolor" android:centerColor="?normalcolor" android:endColor="?normalcolor" />
            </shape>
        </item>
    </layer-list>
</item>

选项2

Drawable是一样的。我刚刚在android:background

中添加了pink style

RelativeLayout的

<RelativeLayout
    style="@style/pink"
    android:layout_width="wrap_content"
    android:layout_alignParentLeft="true"
    android:id="@+id/circlebutton_image_map"
    android:layout_height="wrap_content">
            ....
</RelativeLayout>

风格

<style name="pink">
    <item name="normalcolor">@color/rosa_normal</item>
    <item name="lightcolor">@color/rosa_light</item>
    <item name="shadowcolor">@color/rosa_letter_shadow</item>
    <item name="android:background">@drawable/circlebutton</item>
</style>

相同的LogCat错误：

我不知道如何仅使用样式将这些颜色引用到drawable。

Answer 1

可绘制目录中是否存在@drawable/circlebutton？错误表示未找到此圆圈按钮，可能不存在资源。

如何使用RelativeLayout中的样式引用drawable中的颜色
