activity_layout_linear_item.xml

< ?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="wrap_content" > < TextView android:id="@+id/tv_title" android:layout_width="match_parent" android:layout_height="50dp" android:gravity="center" android:textColor="#000" android:textSize="20sp" /> < /LinearLayout>

activity_linear_recycler_view.xml

< ?xml version="1.0" encoding="utf-8"?> < RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".recyclerview.LinearRecyclerViewActivity"> < android.support.v7.widget.RecyclerView android:id="@+id/rv_main" android:layout_width="match_parent" android:layout_height="wrap_content"/> < /RelativeLayout>

activity_recycler_view.xml

< ?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" android:orientation="vertical"> < Button android:id="@+id/btn_linear" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="列表视图"/> < Button android:id="@+id/btn_hor" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="水平滚动"/> < Button android:id="@+id/btn_grid" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="网格结构"/> < /LinearLayout>
