style attribute 'attr/progressDrawable ' not find

風吹過wu發表於2018-10-22

Android Studio 升級到3.2.1版本，今天自定義ProgressBar的style的時候，我按照往常的方式編寫程式碼，但是始終編譯不過。下圖是錯誤日誌

Android resource linking failed

複製程式碼

解決方法： 在attrs.xml中編寫如下程式碼即可

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="Theme">
        <attr name="progressDrawable" format="reference"/>
        <attr name="indeterminateDrawable" format="reference"/>
    </declare-styleable>

</resources>
