从customView android获取样式引用

我有从LinearLayout扩展的自定义视图。在editText和ImageView内部。 我想为editText设置自定义样式

<resources>
    <declare-styleable name="custom_view">
        <attr name="editTextStyle" format="reference" />
    </declare-styleable>
</resources>

<com.test.CustomView
    xmlns:android="http://schemas.android.com/apk/res"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:editTextStyle="@style/CustomEditTextStyle"
    />

我一直在接受CustomView中的样式引用。 如何从参考中获取样式

---

我很高兴能得到任何帮助！谢谢

您可以按照其中一个Android视图源代码进行操作。 例如，取自TextView.java

/*
     * Look the appearance up without checking first if it exists because
     * almost every TextView has one and it greatly simplifies the logic
     * to be able to parse the appearance first and then let specific tags
     * for this View override it.
