问题 Nested scroll view scrolls smoothly on scrolling down but on scroll up it is sluggish.Collapsing toolbar(with an image view and framelayout) upon scrolling up doesn't renders its content(remains blank). I have tried every flag in collapsing toolbar. <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/coordinatorLayout"

The problem Even though there is "textDirection", "layoutDirection" and "gravity", I can't find the equivalents for the notification builder, not even in the compatibility library.

问题 I get the following error while the gradle sync/build after switching the compileSdkVersion to 25 and using the latest android.support library versions. compile 'com.android.support:appcompat-v7:25.0.0' compile 'com.android.support:design:25.0.0' compile 'com.android.support:recyclerview-v7:25.0.0' Error: No resource found that matches the given name (at 'android:textColorHint' with value '@color/hint_foreground_material_light'). Any idea? EDIT: I think thats because of Adobe Creative SDK...
