Question

当我尝试使约束布局可滚动时，我将约束布局包装在ScrollView中。我在XML布局中没有任何视图的情况下对其进行了测试，它可以正常工作（滚动视图有效，一切都很好）。但是，当我添加一些视图时（例如我发布的XML），它崩溃并显示此错误。该错误将我指向main_activity，但我的main_activity很好（我也将其发布了）

这是错误消息：

Answer 1

解决方案：

 Caused by: android.content.res.Resources$NotFoundException: Resource "athleanx.example.org.myapplication:drawable/train_like_athlete" (7f070097)  is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f070097 a=-1 r=0x7f070097}

您附加到ImageView的可绘制对象出了点问题。

请注意使用：app:srcCompat而非android:srcCompat 在build.gradle(app)

将此行vectorDrawables.useSupportLibrary = true添加到defaultConfig { }内

当我将ScrollView添加到ConstraintLayout时，应用程序崩溃
