以下是recyclerview的布局：

<?xml version="1.0" encoding="utf-8"?>

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="match_parent"

            android:layout_height="480dp"
          android:scaleType="fitXY"
            android:id="@+id/imageView1"/>

            <TextView

                android:layout_height="60dp"
                android:id="@+id/textView1"

                android:layout_centerHorizontal="true"
                android:layout_below="@+id/imageView1"

                android:textSize="20sp"

    </RelativeLayout>

RecyclerView的课程：

尝试使用Picasso

从资源可绘制文件夹加载图片

可以使用以下代码完成此操作：

Picasso.with(context).load(R.drawable.drawableName).into(imageView);
