android-appbarlayout

问题 Working on this Collapsing Toolbar layout everything works fine but the moment I add code in the java class Main activity, error shows up and app crashes. Without java code it was working properly. XML: <?xml version="1.0" encoding="utf-8"?> <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:layout_width="match_parent" android

问题 I have some problems with AppBarLayout and CollapsingToolbarLayout. This is what currently happens: https://www.youtube.com/watch?v=z4yD8rmjSjU The downwards scrolling motion is exactly what I want. However when I scroll up again, the orange bar should appear immediately (which it does), but I want the ImageView to start appearing only when the user has scrolled to the very top. Can anyone help me to achieve this effect? This is my layout xml: <android.support.design.widget.AppBarLayout

问题 So, I am new here just installed Android Studio and then wanted to create a basic activity. But the thing is they want me to install the SDKs and Haxm which is not being installed through SDK manager. I have tried a lot and have used all the ways stated in Stack-overflow to get rid of this but none of their ways has functioned. 回答1: First of all! you need to update your sdk manager that too essential tools are: build tools platform tools tools and android Emulator ..... Now go to LOGCAT ,
