android - 在选择器 xml 中使用颜色

Question

我想为点击而不是图像设置颜色。这样做除了在运行时强制关闭外不会产生任何错误。甚至可以这样做，或者选择器只能用于图像吗？

我在下面尝试的代码:

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_focused="true" android:state_pressed="true" android:background="#00C0FF" />
    <item android:state_focused="true" android:state_pressed="false" android:background="#0060FF" />
    <item android:state_focused="false" android:state_pressed="true" android:background="#00C0FF" />
    <item android:state_focused="false" android:state_pressed="false" android:background="#FFFFFF" />

</selector>

Answer 1

不是根据 documentation

<item>
     Defines a drawable to use during certain states, as described by its attributes. Must be a child of a <selector> element.

    android:drawable
        Drawable resource. **Required.** Reference to a drawable resource.

您可以创建一个简单的可绘制形状来保存颜色

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#33FF33"/>
</shape>
