Android逐渐淘汰support之前的版本,Android studio 导入support.v7也会出错。
在Android developers中找到了添加依赖项的方法:
dependencies {
def recyclerview_version = "1.0.0"
implementation "androidx.recyclerview:recyclerview:$recyclerview_version"
// For control over item selection of both touch and mouse driven selection
implementation "androidx.recyclerview:recyclerview-selection:$recyclerview_version"
}
在build.gradle(Module:app)中找到dependencies,在括号里面输入上述文字。修改布局文件如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
然后就可以使用了
