问题Android Studio找不到与给定名称匹配的资源

Question

I've been searching for hours and I can't figure what's happening on my Android studio project that is broken.

I've just started a new project, did some coding and when I get to layout development just tried to add a custom toggle buton, have add a png file to drawables and a selector XML to change background, of course I've selected it on main layout XML.

Anyway when I try to run it, I get always the same error

Error:(13, 30) No resource found that matches the given name (at 'background' with value '@drawable/boton_on').

That's my selector if this helps:

 <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@drawable/boton_on" android:state_checked="true"/>
        <item android:drawable="@drawable/boton_on" android:state_checked="false"/>
    </selector>

Answer 1

buton_on，未找到图片或xml：此处可能不存在或拼写错误（可能是button_on）（使用ctrl +空格建议可避免此类问题）
