Question

你好我创建了片段@ + id / activity_fragment__eventi__aggiunti，其中有一个recycleview @ + id / reciclerView_eventi_aggiunti，当我的实例片段我把cardview的列表放在@ + id / reciclerView_eventi_aggiunti中时，这个片段：

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_fragment__eventi__aggiunti"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.fra87.eudroid.fragment.Fragment_Eventi_Aggiunti">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/reciclerView_eventi_aggiunti"
        android:scrollbars="vertical"
        android:layout_marginTop="20dp"
        android:layout_marginBottom="100dp"
        android:layout_width="320dp"
        android:layout_height="match_parent">

    </android.support.v7.widget.RecyclerView>

</RelativeLayout>

我想把这个片段放在这个布局的relativelayout @ + id / prova中：

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_lista__eventi"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:scrollbars="vertical"
    tools:context="com.example.fra87.eudroid.activity_class.Lista_Eventi">


    <SearchView
        android:layout_width="match_parent"
        android:layout_height="60dp"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_marginLeft="20dp"
        android:layout_marginStart="20dp"
        android:layout_marginEnd="20dp"
        android:layout_marginTop="10dp"
        android:queryHint="Evento"
        android:id="@+id/cercaEvento"/>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/reciclerView_eventi"
        android:scrollbars="vertical"
        android:layout_below="@+id/cercaEvento"
        android:layout_marginTop="20dp"
        android:layout_marginBottom="100dp"
        android:layout_width="320dp"
        android:layout_height="match_parent"
        android:layout_alignLeft="@id/cercaEvento"
        android:layout_alignRight="@id/cercaEvento" >

    </android.support.v7.widget.RecyclerView>

    <RelativeLayout
        android:layout_width="320dp"
        android:layout_height="match_parent"
        android:id="@+id/prova">

    </RelativeLayout>

    <Button
        android:text="Salva"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:id="@+id/salva_eventi"
        android:layout_alignParentBottom="true"
        android:layout_alignRight="@+id/reciclerView_eventi"
        android:layout_alignEnd="@+id/reciclerView_eventi" />


</RelativeLayout>

我想在relativelayout @ + id / prova中填充片段，但我希望relativelayout在@ + id / reciclerView_eventi及以上按钮@ + id / salva_eventi 我该怎么做？

Answer 1

我认为你可以简单地为RecyclerView使用适配器。无需为列表的每个元素创建片段。

Android将片段放在recycleview下
