首先,对不起,如果这是一个愚蠢的问题.我不是很懒.所以,问题是,我试图在Android应用程序中实现CardView/RecyclerView.我做到了,但问题是卡片彼此隔开,我不知道如何解决它.我探索了代码,但一切似乎都很好.

代码 :

RecyclerView

<android.support.v7.widget.RecyclerView
        android:id="@+id/collapsing_recyclerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"
        android:padding="@dimen/activity_horizontal_margin">

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

CardView项目

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v7.widget.CardView
    android:id="@+id/card_view"
    card_view:cardBackgroundColor="@color/colorAccent"
    android:layout_gravity="center"
    android:layout_width="fill_parent"
    android:layout_height="100dp"
    android:layout_margin="5dp"
    card_view:cardCornerRadius="2dp">

    <TextView
        android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="New Text"
        android:id="@+id/cardview.name" />

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


</LinearLayout>

适配器:

public class MyRecyclerViewAdapter extends RecyclerView
    .Adapter<MyRecyclerViewAdapter
    .DataObjectHolder> {
private static String LOG_TAG = "MyRecyclerViewAdapter";
private ArrayList<CardViewItem> mDataset;
private static MyClickListener myClickListener;

public static class DataObjectHolder extends RecyclerView.ViewHolder
        implements View
        .OnClickListener {
    TextView label;

    public DataObjectHolder(View itemView) {
        super(itemView);
        label = …
