I’m following my teachers tutorial and therefore writing exactly the same code that he has in his example. So I just created a new class to learn RecyclerView but I can’t import RecyclerView On mouse-over, it just says “Cannot resolve symbol RecyclerView“. I use Android Studio 2.3.3. Am I missing something obvious?
import android.support.v7.widget.RecyclerView;
public class CustomAdapter extends RecyclerView.Adapter<ComposedAdapter.Holder> {
//stuff
}
Gradle:
apply plugin: 'com.android.application'android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "sofialarsson.customrecyclerview"
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
}
You need to add dependencies in build.gradle
Use this update gradle file
apply plugin: 'com.android.application'android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "sofialarsson.customrecyclerview"
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile "com.android.support:appcompat-v7:25.0.0"
compile "com.android.support:recyclerview-v7:25.0.0"
testCompile 'junit:junit:4.12'
}
Answer：
Add below dependency in build.gradle;
compile 'com.android.support:design:xx.x.x'
Answer：
If you are using androidx artifacts, add the following to your app level build.gradle
dependencies {
implementation 'androidx.recyclerview:recyclerview:1.1.0'
implementation 'androidx.appcompat:appcompat:1.1.0'
}
Answer：
Just add compile 'com.android.support:recyclerview-v7:25.3.1' dependencies in build.gradle app file like below code
dependencies {
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
}
Answer：
Just add these two dependencies and you are good to go.
compile 'com.android.support:design:25.3.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
Make sure always always use same versions everywhere like you use here 25.3.1.
Also update your buildToolsVersion="25.0.0" .
Thanks!!!
Answer：
Add below dependency in build.gradle
implementation ‘androidx.recyclerview:recyclerview:1.1.0-beta02’

Answer：
to give you an up-to-date and comprehensive answer, you have two choices.
Pre Android 9.0 (pre API 28), you have to use the old Support Library:
dependencies {
compile "com.android.support:appcompat-v7:25.0.0"
compile "com.android.support:recyclerview-v7:25.0.0"
}
For these dependencies, you have to use the version number of your Build Tools Version.
In Android 9.0 (API 28+) and above, you have to use the new Support Library (Noted here https://developer.android.com/topic/libraries/support-library/features#v7):
dependencies {
implementation "androidx.appcompat:appcompat:1.1.0"
implementation "androidx.recyclerview:recyclerview:1.1.0"
}
For these dependencies, you have to use the version numbers from the following pages:
