问题描述
我测试了新的API 21,我尝试创建一个RecyclerView,但我坚持了依赖问题。
I'm testing the new API 21, I try to create a RecyclerView but I'm stuck with a dependency problem.
该错误看起来像
我的布局:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin">
<!-- A RecyclerView with some commonly used attributes -->
<android.support.v7.widget.RecyclerView
android:id="@+id/mRecyclerView"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
和我的摇篮文件
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "com.agonist.samplify"
minSdkVersion 17
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:cardview-v7:+'
compile 'com.android.support:recyclerview-v7:+'
}
我不知道该怎么办。我试图清理/生成项目,但它留在这儿。你知道吗?
I don't know what to do. I tried to clean/build the project but it stay here. Any idea ?
编辑:Finnaly它只是一个IDE preVIEW问题。在执行过程中一切正常。
EDIT : Finnaly it's only an IDE preview problems. During execution everything works
