Question

我想创建一个ImageButton可绘制资源文件，它既包含图像（不为背景展开），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＆＃34; email_selected＆＃34;
选择了按钮：背景变为蓝色，图标为＆＃34; email_selected＆＃34;
默认：背景变为灰色，图标为＆＃34;电子邮件＆＃34;

我试图通过拥有＆＃34; android：state＆＃34;将两个资源文件合二为一。在背景颜色的项目＆＃34;橙＆＃34;和＆＃34;灰＆＃34;但它根本不起作用。

有人可以帮忙吗？

谢谢。

好吧，我必须使用单独的后台资源文件，并使用带有按下和选中状态的选择器。我想你不能在同一资源文件中拥有“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>
<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">
                <solid android:color="@color/orange" />
            </shape>
        </item>
    </layer-list>
</item>
<item android:state_focused="false" android:state_pressed="false">
    <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/gray" />
            </shape>
        </item>
    </layer-list>
</item>
