问题描述

找不到从方法android.support.v7.widget.AppCompatImageHelper.hasOverlappingRendering引用的类'android.graphics.drawable.RippleDrawable'

Could not find class 'android.graphics.drawable.RippleDrawable', referenced from method android.support.v7.widget.AppCompatImageHelper.hasOverlappingRendering

推荐答案

检查您的主题配置.所有主题都必须具有AppCompat的父项.

check your themes config. all themes must have a parent from AppCompat.

像这样:

<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:actionMenuTextColor">@android:color/white</item>
</style>

如果未指定父级，则appcompat库将无效.

if you not specify the parent, the appcompat lib would have no effect.
