How to import RecyclerView for Android L-preview

Question

Trying to use the new RecyclerView from the support library  I downloaded the 20 update for the support library using the SDK manager   I ve added the jar file to the libs folder - and added to build path - no luck using the RecyclerView   Tried to use also the gradle dependency according to Android Developer s API - not sure if this is the right place to look - this page is related more to AndroidTV     com android support recyclerview-v7 20 0     Cannot gradle sync the project   Any ideas

in my case I fixed it by putting compile  com android support recyclerview-v7 22 0 0  as a dependency into my gradle build   with Android studio v  1 2 1 1 and all sdk s updated    It s really annoying when codes are updated so fast and the IDE can t keep track of them  and you have to manually fix for them  wasting time and resources   But well  at last it works

I used a small hack to use the RecyclerView on older devices  I just went into my local m2 repository and picked up the RecyclerView source files and put them into my project   You can find the sourcecode here       lt Android-SDK gt  extras android m2repository com android support recyclerview-v7 21 0 0-rc1 recyclerview-v7-21 0 0-rc1-sources jar

Figured it out   You ll have to add the following gradle dependency    compile  com android support recyclerview-v7      another issue I had compiling was the compileSdkVersion  Apparently  you ll have to compile it against android-L  Your build gradle file should look something like this   apply plugin   android  android       compileSdkVersion  android-L      buildToolsVersion  19 1 0              dependencies       compile fileTree dir   libs   include      jar        compile  com android support recyclerview-v7

User · Answer

If anyone still has this issue - you don t have to change compileSdkVersion  this just defeats the whole purpose of support libraries    Instead  use these in your gradle build file   compile  com android support cardview-v7    compile  com android support recyclerview-v7    compile  com android support palette-v7

If you using the updated or 2018 Version for Android Studio     compile  com android support recyclerview-v7      will give you an error with following message  Configuration  compile  is obsolete and has been replaced with  implementation  and  api   It will be removed at the end of 2018    Try using this   implementation  com android support recyclerview-v7

If You have Compiled SDK Version 22 2 0 then add below dependency for recycler view and cardview additional for support of cardView     for including all the libarary in the directory lib compile fileTree include      jar    dir   libs      for support appcompat   compile  com android support appcompat-v7 22 2 0     for including google support design  it makes possible of implementing material design theme from 2 3 and higher      compile  com android support design 22 2 0      for adding the recycler view use following dependency         compile  com android support recyclerview-v7 22 2 0       After that click on Build- rebuild project and you are done

Just an update    compile  is obsolete now  it has been replaced with  implementation  and  api   It will be removed at the end of 2018 I believe  For more information see  http   d android com r tools update-dependency-configurations html  Also all com android support libraries must use the exact same version specification  in addition  support libraries such as appcompat-v7 and recyclerview-v7 should not use a different version  than the compileSdkVersion

The steps before me are just missing one step   After altering the build gradle  Module app  and adding the following dependencies      compile  com android support cardview-v7 21 0      compile  com android support recyclerview-v7 21 0       Add cardview if necessary   You must then must go to Build   Clean Project to get rid of any errors

import android support v7 widget RecyclerView    In Android Studio  importing is not as intuitive as one would hope  Try importing this bit and see how it helps

A great way to import the RecyclerView into your project is the RecyclerViewLib  This is an open source library which pulled out the RecyclerView to make it safe and easy implement  You can read the author s blog post here   Add the following line as a gradle dependency in your code   dependencies       compile  com twotoasters RecyclerViewLib library 1 0   aar      More info for how to bring in gradle dependencies   Bosnia you re right about that being annoying  Gradle may seem complicated but it is extremely powerful and flexible  Everything is done in the language groovy and learning the gradle system is learning another language just so you can build your Android app  It hurts now  but in the long run you ll love it    Check out the build gradle for the same app  https   github com twotoasters RecyclerViewLib blob master sample build gradle Where it does the following is where it brings the lib into the module  aka the sample app    compile  project    library          exclude group   com android support   module   support-v4       Pay attention to the location of this file  This is not the top level build gradle  Because the lib source is in the same project it is able to do this with the simple   library   The exclude tells the lib to use the sample app s support v4  That isn t necessary but is a good idea  You don t have or want to have the lib s source in your project  so you have to point to the internet for it  In your module s app s build gradle you would put that line from the beginning of this answer in the same location  Or  if following the samples example  you could replace   library  with   com twotoasters RecyclerViewLib library 1 0   aar   and use the excludes
