在我的布局中，我会收到以下警告：

无法实例化以下类： -Android.support.v7.widget.appcompattextview(开放类，显示异常，清除缓存(提示：在您的自定义中使用view.isineditmode(( 在IDE中显示以跳过代码或显示示例数据。如果这 是一个意外的错误，您也可以尝试构建项目，然后 手动刷新布局。

Answer 1

以下问题：

java.lang.NoSuchMethodError: android.support.v4.content.res.ResourcesCompat.getFont(Landroid/content/Context;ILandroid/util/TypedValue;ILandroid/widget/TextView;)Landroid/graphics/Typeface;

可能是因为Glide严格使用支持库中不存在的功能26.1.0。Glide使用支持库27.1.0。这似乎与ResourceCompat.getFont((相关，该font((从支持库27.1.0。

开始。

尝试将compileSdkVersion和targetSdkVersion更新为 27 。并将所有支持库更改为 27.1.0 。
