阅读更多关于 AppBarLayout child doesn't collapse when scrolling

问题 I have a AppBarLayout which contains an horizontal RecyclerView among its children. The sibling of the AppBarLayout is a ViewPager (which contains a vertical RecyclerView ).

阅读更多关于 patch support library using Android Studio

问题 I've moved my project to Android Studio a month ago, and I'm glad I did, despite the need to switch to a new (and more powerful) build system (gradle).

阅读更多关于 @IntDef annotation and return value from other's code that cannot be annotated or how to temporarily disable annotation from affecting the code?

I am using IntDef from Android Support annotation in my code (but my question is wider in scope so please keep reading :) like this: public class UiLockMode { @IntDef({DEFAULT, NONE, VISIBLE, TRANSPARENT}) @Retention(RetentionPolicy.SOURCE) public @interface AllowedValues {} public static final int DEFAULT = 0; public static final int NONE = 1; public static final int VISIBLE = 2; public static final int TRANSPARENT = 3; } Next, I got some other methods annotated with it like this: protected void setLockMode(@UiLockMode.AllowedValues int lockMode) { ... At that point is all fine and nice but

I upgraded to Android Support Library 23.2.0 and added vectorDrawables.useSupportLibrary = true to my build.gradle, so that I have vector drawable support for apis lower than 21.

The app compiles and works perfectly fine, but code analysis reports: Error:(56, 9) Unexpected namespace prefix "app" found for tag ImageView Why is this the case? Why is it compiling although I am getting errors? EDIT: I have added
