I'm trying to use the method findFirstVisibleItemPosition()
from a LinearLayoutManager
. The apis show that this method exists, but it is not recognized nor shown in autocompletion.
Other methods from this layout work (some at least), and android.support.v7.widget.LinearLayoutManager
is imported.
What could be wrong?
edit: here´s my build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.example.skate.socialskate"
minSdkVersion 21
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.gms:play-services:7.0.0'
compile 'com.android.support:cardview-v7:22.1.0'
compile 'com.android.support:recyclerview-v7:21.0.+'
compile 'com.android.support:support-v13:22.1.0'
compile 'de.hdodenhof:circleimageview:1.2.1'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'org.codehaus.jackson:jackson-mapper-asl:1.9.13'
compile 'org.jsoup:jsoup:1.8.2'
}
您需要将一个appcompat添加到build.gradle
:
compile 'com.android.support:appcompat-v7:22.1.1'
