ImageButton与图像图标，彩色背景和边框

提问于

我想创建一个ImageButton可绘制资源文件，它既包含图像（不为背景扩展），彩色背景和右边框和下边框 . 此外，我希望state_pressed，state_selected和默认状态具有不同的设置 .

现在我已经设法为所有状态的图像创建xml资源文件：

<item android:state_selected="true" android:drawable="@drawable/emailselected" />
<item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/emailselected" />
<item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/emailselected" />
<item android:state_focused="true" android:drawable="@drawable/emailseleted" />
<item android:state_focused="false" android:state_pressed="false" android:drawable="@drawable/email" />

我还有背景和右边框和下边框xml资源文件：

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/darkgray" />
        </shape>
    </item>

    <item
        android:bottom="1dp"
        android:right="1dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/orange" />
        </shape>
    </item>

    <item
        android:bottom="1dp"
        android:right="1dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/gray" />
        </shape>
    </item>
</layer-list>

我想将所有这些组合在一个资源文件中 . 可能吗？所以基本上我想：

按下

  • 按钮：背景变为蓝色，图标为“email_selected”

  • 选择了按钮：背景变为蓝色，图标为“email_selected”

  • 默认：背景变为灰色，图标为“电子邮件”

我试图将两个资源文件组合在一起，在背景颜色“橙色”和“灰色”的项目中使用“android：state”，但它根本不起作用 .

有人可以帮忙吗？

谢谢 .

    好吧，我不得不使用单独的后台资源文件，并使用状态按下和选择项目的选择器 . 我想你不能在同一资源文件中有“背景”和“可绘制” . 这是我的代码：

    <selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true">
    <layer-list>
        <item>
            <shape android:shape="rectangle">
                <solid android:color="@color/darkgray" />
            </shape>
        </item>

        <item android:state_focused="false" android:state_pressed="false" android:bottom="1dp" android:right="1dp">
            <shape android:shape="rectangle">
                <solid android:color="@color/orange" />
            </shape>
        </item>
    </layer-list>
</item>
<item android:state_focused="true" android:state_pressed="true">
    <layer-list>
        <item>
            <shape android:shape="rectangle">
                <solid android:color="@color/darkgray" />
            </shape>
        </item>

        <item android:state_focused="false" android:state_pressed="false" android:bottom="1dp" android:right="1dp">
            <shape android:shape="rectangle">
                <solid android:color="@color/orange" />
            </shape>
        </item>
    </layer-list>
</item>
<item android:state_focused="false" android:state_pressed="true">
    <layer-list>
        <item>
            <shape android:shape="rectangle">
                <solid android:color="@color/darkgray" />
            </shape>
        </item>

        <item android:state_focused="false" android:state_pressed="false" android:bottom="1dp" android:right="1dp">
            <shape android:shape="rectangle">
                <solid android:color="@color/orange" />
            </shape>
        </item>
    </layer-list>

<item android:state_focused="true">
    <layer-list>
        <item>
            <shape android:shape="rectangle">
                <solid android:color="@color/darkgray" />
            </shape>
        </item>

        <item android:state_focused="false" android:state_pressed="false" android:bottom="1dp" android:right="1dp">
            <shape android:shape="rectangle">

            </shape>

            </shape>
        </item>
    </layer-list>
</item>
