我正在跟随我的老师的教程,所以我正在完全按照他在示例中的代码编写。因此,我只是创建了一个新类来学习
RecyclerView
,但我无法导入RecyclerView
。鼠标悬停时,它只会显示“无法解析符号RecyclerView”。我使用的是Android Studio 2.3.3。
我是否漏掉了一些明显的东西?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'
}
compile "com.android.support:recyclerview-v7
